Installation

-

phpMyAdmin does not apply any special security methods to the MySQL -database server. It is still the system administrator’s job to grant -permissions on the MySQL databases properly. phpMyAdmin’s Users -page can be used for this.

-
-

Warning

-

Mac users should note that if you are on a version before -Mac OS X, StuffIt unstuffs with Mac formats. So you’ll have -to resave as in BBEdit to Unix style ALL phpMyAdmin scripts before -uploading them to your server, as PHP seems not to like Mac-style -end of lines character (“\r”).

-
-
-

Linux distributions

-

phpMyAdmin is included in most Linux distributions. It is recommended to use -distribution packages when possible - they usually provide integration to your -distribution and you will automatically get security updates from your distribution.

-
-

Debian and Ubuntu

-

Debian’s package repositories include a phpMyAdmin package, but be aware that -the configuration file is maintained in /etc/phpmyadmin and may differ in -some ways from the official phpMyAdmin documentation. Specifically, it does:

- -
-

See also

-

More information can be found in README.Debian -(it is installed as /usr/share/doc/phmyadmin/README.Debian with the package).

-
-
-
-

OpenSUSE

-

OpenSUSE already comes with phpMyAdmin package, just install packages from -the openSUSE Build Service.

-
-
-

Gentoo

-

Gentoo ships the phpMyAdmin package, both in a near-stock configuration as well -as in a webapp-config configuration. Use emerge dev-db/phpmyadmin to -install.

-
-
-

Mandriva

-

Mandriva ships the phpMyAdmin package in their contrib branch and can be -installed via the usual Control Center.

-
-
-

Fedora

-

Fedora ships the phpMyAdmin package, but be aware that the configuration file -is maintained in /etc/phpMyAdmin/ and may differ in some ways from the -official phpMyAdmin documentation.

-
-
-

Red Hat Enterprise Linux

-

Red Hat Enterprise Linux itself and thus derivatives like CentOS don’t -ship phpMyAdmin, but the Fedora-driven repository -Extra Packages for Enterprise Linux (EPEL) -is doing so, if it’s -enabled. -But be aware that the configuration file is maintained in -/etc/phpMyAdmin/ and may differ in some ways from the -official phpMyAdmin documentation.

-
-
-
-

Installing on Windows

-

The easiest way to get phpMyAdmin on Windows is using third party products -which include phpMyAdmin together with a database and web server such as -XAMPP.

-

You can find more of such options at Wikipedia.

-
-
-

Installing from Git

-

In order to install from Git, you’ll need a few supporting applications:

-
    -
  • Git to download the source, or you can download the most recent source directly from Github
  • -
  • Composer
  • -
  • Node.js (version 8 or higher)
  • -
  • Yarn
  • -
-

You can clone current phpMyAdmin source from -https://github.com/phpmyadmin/phpmyadmin.git:

-
git clone https://github.com/phpmyadmin/phpmyadmin.git
-
-
-

Additionally you need to install dependencies using Composer:

-
composer update
-
-
-

If you do not intend to develop, you can skip the installation of developer tools -by invoking:

-
composer update --no-dev
-
-
-

Finally, you’ll need to use Yarn to install some JavaScript dependencies:

-
yarn install
-
-
-
-
-

Installing using Composer

-

You can install phpMyAdmin using the Composer tool, since 4.7.0 the releases -are automatically mirrored to the default Packagist repository.

-
-

Note

-

The content of the Composer repository is automatically generated -separately from the releases, so the content doesn’t have to be -100% same as when you download the tarball. There should be no -functional differences though.

-
-

To install phpMyAdmin simply run:

-
composer create-project phpmyadmin/phpmyadmin
-
-
-

Alternatively you can use our own composer repository, which contains -the release tarballs and is available at -<https://www.phpmyadmin.net/packages.json>:

-
composer create-project phpmyadmin/phpmyadmin --repository-url=https://www.phpmyadmin.net/packages.json --no-dev
-
-
-
-
-

Installing using Docker

-

phpMyAdmin comes with a Docker image, which you can easily deploy. You can -download it using:

-
docker pull phpmyadmin/phpmyadmin
-
-
-

The phpMyAdmin server will listen on port 80. It supports several ways of -configuring the link to the database server, either by Docker’s link feature -by linking your database container to db for phpMyAdmin (by specifying ---link your_db_host:db) or by environment variables (in this case it’s up -to you to set up networking in Docker to allow the phpMyAdmin container to access -the database container over the network).

-
-

Docker environment variables

-

You can configure several phpMyAdmin features using environment variables:

-
-
-PMA_ARBITRARY
-

Allows you to enter a database server hostname on login form.

- -
- -
-
-PMA_HOST
-

Hostname or IP address of the database server to use.

- -
- -
-
-PMA_HOSTS
-

Comma-separated hostnames or IP addresses of the database servers to use.

-
-

Note

-

Used only if PMA_HOST is empty.

-
-
- -
-
-PMA_VERBOSE
-

Verbose name of the database server.

- -
- -
-
-PMA_VERBOSES
-

Comma-separated verbose name of the database servers.

-
-

Note

-

Used only if PMA_VERBOSE is empty.

-
-
- -
-
-PMA_USER
-

User name to use for Config authentication mode.

-
- -
-
-PMA_PASSWORD
-

Password to use for Config authentication mode.

-
- -
-
-PMA_PORT
-

Port of the database server to use.

-
- -
-
-PMA_PORTS
-

Comma-separated ports of the database server to use.

-
-

Note

-

Used only if PMA_PORT is empty.

-
-
- -
-
-PMA_ABSOLUTE_URI
-

The fully-qualified path (https://pma.example.net/) where the reverse -proxy makes phpMyAdmin available.

- -
- -

By default, Cookie authentication mode is used, but if PMA_USER and -PMA_PASSWORD are set, it is switched to Config authentication mode.

-
-

Note

-

The credentials you need to log in are stored in the MySQL server, in case -of Docker image, there are various ways to set it (for example -MYSQL_ROOT_PASSWORD when starting the MySQL container). Please check -documentation for MariaDB container -or MySQL container.

-
-
-
-

Customizing configuration

-

Additionally configuration can be tweaked by /etc/phpmyadmin/config.user.inc.php. If -this file exists, it will be loaded after configuration is generated from above -environment variables, so you can override any configuration variable. This -configuration can be added as a volume when invoking docker using --v /some/local/directory/config.user.inc.php:/etc/phpmyadmin/config.user.inc.php parameters.

-

Note that the supplied configuration file is applied after Docker environment variables, -but you can override any of the values.

-

For example to change the default behavior of CSV export you can use the following -configuration file:

-
<?php
-$cfg['Export']['csv_columns'] = true;
-
-
-

You can also use it to define server configuration instead of using the -environment variables listed in Docker environment variables:

-
<?php
-/* Override Servers array */
-$cfg['Servers'] = [
-    1 => [
-        'auth_type' => 'cookie',
-        'host' => 'mydb1',
-        'port' => 3306,
-        'verbose' => 'Verbose name 1',
-    ],
-    2 => [
-        'auth_type' => 'cookie',
-        'host' => 'mydb2',
-        'port' => 3306,
-        'verbose' => 'Verbose name 2',
-    ],
-];
-
-
-
-

-

See Configuration for detailed description of configuration options.

-
-
-
-

Docker Volumes

-

You can use the following volumes to customize image behavior:

-

/etc/phpmyadmin/config.user.inc.php

-
-
Can be used for additional settings, see the previous chapter for more details.
-

/sessions/

-
-
Directory where PHP sessions are stored. You might want to share this -for example when using Signon authentication mode.
-

/www/themes/

-
-
Directory where phpMyAdmin looks for themes. By default only those shipped -with phpMyAdmin are included, but you can include additional phpMyAdmin -themes (see Custom Themes) by using Docker volumes.
-
-
-

Docker Examples

-

To connect phpMyAdmin to a given server use:

-
docker run --name myadmin -d -e PMA_HOST=dbhost -p 8080:80 phpmyadmin/phpmyadmin
-
-
-

To connect phpMyAdmin to more servers use:

-
docker run --name myadmin -d -e PMA_HOSTS=dbhost1,dbhost2,dbhost3 -p 8080:80 phpmyadmin/phpmyadmin
-
-
-

To use arbitrary server option:

-
docker run --name myadmin -d --link mysql_db_server:db -p 8080:80 -e PMA_ARBITRARY=1 phpmyadmin/phpmyadmin
-
-
-

You can also link the database container using Docker:

-
docker run --name phpmyadmin -d --link mysql_db_server:db -p 8080:80 phpmyadmin/phpmyadmin
-
-
-

Running with additional configuration:

-
docker run --name phpmyadmin -d --link mysql_db_server:db -p 8080:80 -v /some/local/directory/config.user.inc.php:/etc/phpmyadmin/config.user.inc.php phpmyadmin/phpmyadmin
-
-
-

Running with additional themes:

-
docker run --name phpmyadmin -d --link mysql_db_server:db -p 8080:80 -v /custom/phpmyadmin/theme/:/www/themes/theme/ phpmyadmin/phpmyadmin
-
-
-
-
-

Using docker-compose

-

Alternatively, you can also use docker-compose with the docker-compose.yml from -<https://github.com/phpmyadmin/docker>. This will run phpMyAdmin with an -arbitrary server - allowing you to specify MySQL/MariaDB server on the login page.

-
docker-compose up -d
-
-
-
-
-

Customizing configuration file using docker-compose

-

You can use an external file to customize phpMyAdmin configuration and pass it -using the volumes directive:

-
phpmyadmin:
-    image: phpmyadmin/phpmyadmin
-    container_name: phpmyadmin
-    environment:
-     - PMA_ARBITRARY=1
-    restart: always
-    ports:
-     - 8080:80
-    volumes:
-     - /sessions
-     - ~/docker/phpmyadmin/config.user.inc.php:/etc/phpmyadmin/config.user.inc.php
-     - /custom/phpmyadmin/theme/:/www/themes/theme/
-
-
- -
-
-

Running behind haproxy in a subdirectory

-

When you want to expose phpMyAdmin running in a Docker container in a -subdirectory, you need to rewrite the request path in the server proxying the -requests.

-

For example, using haproxy it can be done as:

-
frontend http
-    bind *:80
-    option forwardfor
-    option http-server-close
-
-    ### NETWORK restriction
-    acl LOCALNET  src 10.0.0.0/8 192.168.0.0/16 172.16.0.0/12
-
-    # /phpmyadmin
-    acl phpmyadmin  path_dir /phpmyadmin
-    use_backend phpmyadmin if phpmyadmin LOCALNET
-
-backend phpmyadmin
-    mode http
-
-    reqirep  ^(GET|POST|HEAD)\ /phpmyadmin/(.*)     \1\ /\2
-
-    # phpMyAdmin container IP
-    server localhost     172.30.21.21:80
-
-
-

When using traefik, something like following should work:

-
defaultEntryPoints = ["http"]
-[entryPoints]
-  [entryPoints.http]
-  address = ":80"
-    [entryPoints.http.redirect]
-      regex = "(http:\\/\\/[^\\/]+\\/([^\\?\\.]+)[^\\/])$"
-      replacement = "$1/"
-
-[backends]
-  [backends.myadmin]
-    [backends.myadmin.servers.myadmin]
-    url="http://internal.address.to.pma"
-
-[frontends]
-   [frontends.myadmin]
-   backend = "myadmin"
-   passHostHeader = true
-     [frontends.myadmin.routes.default]
-     rule="PathPrefixStrip:/phpmyadmin/;AddPrefix:/"
-
-
-

You then should specify PMA_ABSOLUTE_URI in the docker-compose -configuration:

-
version: '2'
-
-services:
-  phpmyadmin:
-    restart: always
-    image: phpmyadmin/phpmyadmin
-    container_name: phpmyadmin
-    hostname: phpmyadmin
-    domainname: example.com
-    ports:
-      - 8000:80
-    environment:
-      - PMA_HOSTS=172.26.36.7,172.26.36.8,172.26.36.9,172.26.36.10
-      - PMA_VERBOSES=production-db1,production-db2,dev-db1,dev-db2
-      - PMA_USER=root
-      - PMA_PASSWORD=
-      - PMA_ABSOLUTE_URI=http://example.com/phpmyadmin/
-
-
-
-
-
-

Quick Install

-
    -
  1. Choose an appropriate distribution kit from the phpmyadmin.net -Downloads page. Some kits contain only the English messages, others -contain all languages. We’ll assume you chose a kit whose name -looks like phpMyAdmin-x.x.x -all-languages.tar.gz.
  2. -
  3. Ensure you have downloaded a genuine archive, see Verifying phpMyAdmin releases.
  4. -
  5. Untar or unzip the distribution (be sure to unzip the subdirectories): -tar -xzvf phpMyAdmin_x.x.x-all-languages.tar.gz in your -webserver’s document root. If you don’t have direct access to your -document root, put the files in a directory on your local machine, -and, after step 4, transfer the directory on your web server using, -for example, FTP.
  6. -
  7. Ensure that all the scripts have the appropriate owner (if PHP is -running in safe mode, having some scripts with an owner different from -the owner of other scripts will be a problem). See 4.2 What’s the preferred way of making phpMyAdmin secure against evil access? and -1.26 I just installed phpMyAdmin in my document root of IIS but I get the error “No input file specified” when trying to run phpMyAdmin. for suggestions.
  8. -
  9. Now you must configure your installation. There are two methods that -can be used. Traditionally, users have hand-edited a copy of -config.inc.php, but now a wizard-style setup script is provided -for those who prefer a graphical installation. Creating a -config.inc.php is still a quick way to get started and needed for -some advanced features.
  10. -
-
-

Manually creating the file

-

To manually create the file, simply use your text editor to create the -file config.inc.php (you can copy config.sample.inc.php to get -a minimal configuration file) in the main (top-level) phpMyAdmin -directory (the one that contains index.php). phpMyAdmin first -loads libraries/config.default.php and then overrides those values -with anything found in config.inc.php. If the default value is -okay for a particular setting, there is no need to include it in -config.inc.php. You’ll probably need only a few directives to get going; a -simple configuration may look like this:

-
<?php
-// use here a value of your choice at least 32 chars long
-$cfg['blowfish_secret'] = '1{dd0`<Q),5XP_:R9UK%%8\"EEcyH#{o';
-
-$i=0;
-$i++;
-$cfg['Servers'][$i]['auth_type']     = 'cookie';
-// if you insist on "root" having no password:
-// $cfg['Servers'][$i]['AllowNoPassword'] = true;
-
-
-

Or, if you prefer to not be prompted every time you log in:

-
<?php
-
-$i=0;
-$i++;
-$cfg['Servers'][$i]['user']          = 'root';
-$cfg['Servers'][$i]['password']      = 'cbb74bc'; // use here your password
-$cfg['Servers'][$i]['auth_type']     = 'config';
-
-
-
-

Warning

-

Storing passwords in the configuration is insecure as anybody can then -manipulate your database.

-
-

For a full explanation of possible configuration values, see the -Configuration of this document.

-
-
-

Using the Setup script

-

Instead of manually editing config.inc.php, you can use phpMyAdmin’s -setup feature. The file can be generated using the setup and you can download it -for upload to the server.

-

Next, open your browser and visit the location where you installed phpMyAdmin, -with the /setup suffix. The changes are not saved to the server, you need to -use the Download button to save them to your computer and then upload -to the server.

-

Now the file is ready to be used. You can choose to review or edit the -file with your favorite editor, if you prefer to set some advanced -options that the setup script does not provide.

-
    -
  1. If you are using the auth_type “config”, it is suggested that you -protect the phpMyAdmin installation directory because using config -does not require a user to enter a password to access the phpMyAdmin -installation. Use of an alternate authentication method is -recommended, for example with HTTP–AUTH in a .htaccess file or switch to using -auth_type cookie or http. See the ISPs, multi-user installations -for additional information, especially 4.4 phpMyAdmin always gives “Access denied” when using HTTP authentication..
  2. -
  3. Open the main phpMyAdmin directory in your browser. -phpMyAdmin should now display a welcome screen and your databases, or -a login dialog if using HTTP or -cookie authentication mode.
  4. -

-

Setup script on Debian, Ubuntu and derivatives

-

Debian and Ubuntu have changed the way in which the setup script is enabled and disabled, in a way -that single command has to be executed for either of these.

-

To allow editing configuration invoke:

-
/usr/sbin/pma-configure
-
-
-

To block editing configuration invoke:

-
/usr/sbin/pma-secure
-
-
-
-
-

Setup script on openSUSE

-

Some openSUSE releases do not include setup script in the package. In case you -want to generate configuration on these you can either download original -package from <https://www.phpmyadmin.net/> or use setup script on our demo -server: <https://demo.phpmyadmin.net/master/setup/>.

-

-

Verifying phpMyAdmin releases

-

Since July 2015 all phpMyAdmin releases are cryptographically signed by the -releasing developer, who through January 2016 was Marc Delisle. His key id is -0xFEFC65D181AF644A, his PGP fingerprint is:

-
436F F188 4B1A 0C3F DCBF 0D79 FEFC 65D1 81AF 644A
-
-
-

and you can get more identification information from <https://keybase.io/lem9>.

-

Beginning in January 2016, the release manager is Isaac Bennetch. His key id is -0xCE752F178259BD92, and his PGP fingerprint is:

-
3D06 A59E CE73 0EB7 1B51 1C17 CE75 2F17 8259 BD92
-
-
-

and you can get more identification information from <https://keybase.io/ibennetch>.

-

Some additional downloads (for example themes) might be signed by Michal Čihař. His key id is -0x9C27B31342B7511D, and his PGP fingerprint is:

-
63CB 1DF1 EF12 CF2A C0EE 5A32 9C27 B313 42B7 511D
-
-
-

and you can get more identification information from <https://keybase.io/nijel>.

-

You should verify that the signature matches the archive you have downloaded. -This way you can be sure that you are using the same code that was released. -You should also verify the date of the signature to make sure that you -downloaded the latest version.

-

Each archive is accompanied by .asc files which contain the PGP signature -for it. Once you have both of them in the same folder, you can verify the signature:

-
$ gpg --verify phpMyAdmin-4.5.4.1-all-languages.zip.asc
-gpg: Signature made Fri 29 Jan 2016 08:59:37 AM EST using RSA key ID 8259BD92
-gpg: Can't check signature: public key not found
-
-
-

As you can see gpg complains that it does not know the public key. At this -point, you should do one of the following steps:

- -
$ gpg --import phpmyadmin.keyring
-
-
-
    -
  • Download and import the key from one of the key servers:
  • -
-
$ gpg --keyserver hkp://pgp.mit.edu --recv-keys 3D06A59ECE730EB71B511C17CE752F178259BD92
-gpg: requesting key 8259BD92 from hkp server pgp.mit.edu
-gpg: key 8259BD92: public key "Isaac Bennetch <bennetch@gmail.com>" imported
-gpg: no ultimately trusted keys found
-gpg: Total number processed: 1
-gpg:               imported: 1  (RSA: 1)
-
-
-

This will improve the situation a bit - at this point, you can verify that the -signature from the given key is correct but you still can not trust the name used -in the key:

-
$ gpg --verify phpMyAdmin-4.5.4.1-all-languages.zip.asc
-gpg: Signature made Fri 29 Jan 2016 08:59:37 AM EST using RSA key ID 8259BD92
-gpg: Good signature from "Isaac Bennetch <bennetch@gmail.com>"
-gpg:                 aka "Isaac Bennetch <isaac@bennetch.org>"
-gpg: WARNING: This key is not certified with a trusted signature!
-gpg:          There is no indication that the signature belongs to the owner.
-Primary key fingerprint: 3D06 A59E CE73 0EB7 1B51  1C17 CE75 2F17 8259 BD92
-
-
-

The problem here is that anybody could issue the key with this name. You need to -ensure that the key is actually owned by the mentioned person. The GNU Privacy -Handbook covers this topic in the chapter Validating other keys on your public -keyring. The most reliable method is to meet the developer in person and -exchange key fingerprints, however, you can also rely on the web of trust. This way -you can trust the key transitively though signatures of others, who have met -the developer in person. For example, you can see how Isaac’s key links to -Linus’s key.

-

Once the key is trusted, the warning will not occur:

-
$ gpg --verify phpMyAdmin-4.5.4.1-all-languages.zip.asc
-gpg: Signature made Fri 29 Jan 2016 08:59:37 AM EST using RSA key ID 8259BD92
-gpg: Good signature from "Isaac Bennetch <bennetch@gmail.com>" [full]
-
-
-

Should the signature be invalid (the archive has been changed), you would get a -clear error regardless of the fact that the key is trusted or not:

-
$ gpg --verify phpMyAdmin-4.5.4.1-all-languages.zip.asc
-gpg: Signature made Fri 29 Jan 2016 08:59:37 AM EST using RSA key ID 8259BD92
-gpg: BAD signature from "Isaac Bennetch <bennetch@gmail.com>" [unknown]
-
-

phpMyAdmin configuration storage

-
-

Changed in version 3.4.0: Prior to phpMyAdmin 3.4.0 this was called Linked Tables Infrastructure, but -the name was changed due to the extended scope of the storage.

-
-

For a whole set of additional features (Bookmarks, comments, SQL-history, -tracking mechanism, PDF-generation, Transformations, Relations -etc.) you need to create a set of special tables. Those tables can be located -in your own database, or in a central database for a multi-user installation -(this database would then be accessed by the controluser, so no other user -should have rights to it).

-
-

Zero configuration

-

In many cases, this database structure can be automatically created and -configured. This is called “Zero Configuration” mode and can be particularly -useful in shared hosting situations. “Zeroconf” mode is on by default, to -disable set $cfg['ZeroConf'] to false.

-

The following three scenarios are covered by the Zero Configuration mode:

-
    -
  • When entering a database where the configuration storage tables are not -present, phpMyAdmin offers to create them from the Operations tab.
  • -
  • When entering a database where the tables do already exist, the software -automatically detects this and begins using them. This is the most common -situation; after the tables are initially created automatically they are -continually used without disturbing the user; this is also most useful on -shared hosting where the user is not able to edit config.inc.php and -usually the user only has access to one database.
  • -
  • When having access to multiple databases, if the user first enters the -database containing the configuration storage tables then switches to -another database, -phpMyAdmin continues to use the tables from the first database; the user is -not prompted to create more tables in the new database.
  • -
-
-
-

Manual configuration

-

Please look at your ./sql/ directory, where you should find a -file called create_tables.sql. (If you are using a Windows server, -pay special attention to 1.23 I’m running MySQL on a Win32 machine. Each time I create a new table the table and column names are changed to lowercase!).

-

If you already had this infrastructure and:

-
    -
  • upgraded to MySQL 4.1.2 or newer, please use -sql/upgrade_tables_mysql_4_1_2+.sql.
  • -
  • upgraded to phpMyAdmin 4.3.0 or newer from 2.5.0 or newer (<= 4.2.x), -please use sql/upgrade_column_info_4_3_0+.sql.
  • -
  • upgraded to phpMyAdmin 4.7.0 or newer from 4.3.0 or newer, -please use sql/upgrade_tables_4_7_0+.sql.
  • -
-

and then create new tables by importing sql/create_tables.sql.

-

You can use your phpMyAdmin to create the tables for you. Please be -aware that you may need special (administrator) privileges to create -the database and tables, and that the script may need some tuning, -depending on the database name.

-

After having imported the sql/create_tables.sql file, you -should specify the table names in your config.inc.php file. The -directives used for that can be found in the Configuration.

-

You will also need to have a controluser -($cfg['Servers'][$i]['controluser'] and -$cfg['Servers'][$i]['controlpass'] settings) -with the proper rights to those tables. For example you can create it -using following statement:

-

And for any MariaDB version:

-
CREATE USER 'pma'@'localhost' IDENTIFIED VIA mysql_native_password USING 'pmapass';
-GRANT SELECT, INSERT, UPDATE, DELETE ON `<pma_db>`.* TO 'pma'@'localhost';
-

For MySQL 8.0 and newer:

-
CREATE USER 'pma'@'localhost' IDENTIFIED WITH caching_sha2_password BY 'pmapass';
-GRANT SELECT, INSERT, UPDATE, DELETE ON <pma_db>.* TO 'pma'@'localhost';
-
-
-

For MySQL older than 8.0:

-
CREATE USER 'pma'@'localhost' IDENTIFIED WITH mysql_native_password AS 'pmapass';
-GRANT SELECT, INSERT, UPDATE, DELETE ON <pma_db>.* TO 'pma'@'localhost';
-
-
-

Note that MySQL installations with PHP older than 7.4 and MySQL newer than 8.0 may require -using the mysql_native_password authentication as a workaround, see -1.45 I get an error message about unknown authentication method caching_sha2_password when trying to log in for details.

Upgrading from an older version

-
-

Warning

-

Never extract the new version over an existing installation of -phpMyAdmin, always first remove the old files keeping just the -configuration.

-

This way, you will not leave any old or outdated files in the directory, -which can have severe security implications or can cause various breakages.

-
-

Simply copy config.inc.php from your previous installation into -the newly unpacked one. Configuration files from old versions may -require some tweaking as some options have been changed or removed. -For compatibility with PHP 5.3 and later, remove a -set_magic_quotes_runtime(0); statement that you might find near -the end of your configuration file.

-

You should not copy libraries/config.default.php over -config.inc.php because the default configuration file is version- -specific.

-

The complete upgrade can be performed in a few simple steps:

-
    -
  1. Download the latest phpMyAdmin version from <https://www.phpmyadmin.net/downloads/>.
  2. -
  3. Rename existing phpMyAdmin folder (for example to phpmyadmin-old).
  4. -
  5. Unpack freshly downloaded phpMyAdmin to the desired location (for example phpmyadmin).
  6. -
  7. Copy config.inc.php` from old location (phpmyadmin-old) to the new one (phpmyadmin).
  8. -
  9. Test that everything works properly.
  10. -
  11. Remove backup of a previous version (phpmyadmin-old).
  12. -
-

If you have upgraded your MySQL server from a version previous to 4.1.2 to -version 5.x or newer and if you use the phpMyAdmin configuration storage, you -should run the SQL script found in -sql/upgrade_tables_mysql_4_1_2+.sql.

-

If you have upgraded your phpMyAdmin to 4.3.0 or newer from 2.5.0 or -newer (<= 4.2.x) and if you use the phpMyAdmin configuration storage, you -should run the SQL script found in -sql/upgrade_column_info_4_3_0+.sql.

-

Do not forget to clear the browser cache and to empty the old session by -logging out and logging in again.

-
-
-

Using authentication modes

-

HTTP and cookie authentication modes are recommended in a multi-user -environment where you want to give users access to their own database and -don’t want them to play around with others. Nevertheless, be aware that MS -Internet Explorer seems to be really buggy about cookies, at least till version -6. Even in a single-user environment, you might prefer to use HTTP -or cookie mode so that your user/password pair are not in clear in the -configuration file.

-

HTTP and cookie authentication -modes are more secure: the MySQL login information does not need to be -set in the phpMyAdmin configuration file (except possibly for the -$cfg['Servers'][$i]['controluser']). -However, keep in mind that the password travels in plain text unless -you are using the HTTPS protocol. In cookie mode, the password is -stored, encrypted with the AES algorithm, in a temporary cookie.

-

Then each of the true users should be granted a set of privileges -on a set of particular databases. Normally you shouldn’t give global -privileges to an ordinary user unless you understand the impact of those -privileges (for example, you are creating a superuser). -For example, to grant the user real_user with all privileges on -the database user_base:

-
GRANT ALL PRIVILEGES ON user_base.* TO 'real_user'@localhost IDENTIFIED BY 'real_password';
-
-
-

What the user may now do is controlled entirely by the MySQL user management -system. With HTTP or cookie authentication mode, you don’t need to fill the -user/password fields inside the $cfg['Servers'].

- -
-

HTTP authentication mode

- -
-

Note

-

There is no way to do proper logout in HTTP authentication, most browsers -will remember credentials until there is no different successful -authentication. Because of this, this method has a limitation that you can not -login with the same user after logout.

-
-
- -
-

Signon authentication mode

- -

The very basic example of saving credentials in a session is available as -examples/signon.php:

-
<?php
-/* vim: set expandtab sw=4 ts=4 sts=4: */
-/**

-/* Create signon session */
-$session_name = 'SignonSession';
-session_name($session_name);
-// Uncomment and change the following line to match your $cfg['SessionSavePath']
-//session_save_path('/foobar');
-@session_start();
-

-if (isset($_POST['user'])) {
-    /* Store there credentials */

If you intend to pass the credentials using some other means than, you have to -implement wrapper in PHP to get that data and set it to -$cfg['Servers'][$i]['SignonScript']. There is a very minimal example -in examples/signon-script.php:

-/**
- * This function returns username and password.

- * @param string $user User name
- *
- * @return array
- */
-function get_login_credentials($user)
-{
-    /* Optionally we can use passed username */
-    if (! empty($user)) {
-        return [
-            $user,
-            'password',
-        ];
-    }
-
-    /* Here we would retrieve the credentials */
-    return [
-        'root',
-        '',
-    ];
-}
-
-
- -
-
-

Config authentication mode

-
    -
  • This mode is sometimes the less secure one because it requires you to fill the -$cfg['Servers'][$i]['user'] and -$cfg['Servers'][$i]['password'] -fields (and as a result, anyone who can read your config.inc.php -can discover your username and password).
  • -
  • In the ISPs, multi-user installations section, there is an entry explaining how -to protect your configuration file.
  • -
  • For additional security in this mode, you may wish to consider the -Host authentication $cfg['Servers'][$i]['AllowDeny']['order'] -and $cfg['Servers'][$i]['AllowDeny']['rules'] configuration directives.
  • -
  • Unlike cookie and http, does not require a user to log in when first -loading the phpMyAdmin site. This is by design but could allow any -user to access your installation. Use of some restriction method is -suggested, perhaps a .htaccess file with the HTTP-AUTH directive or disallowing -incoming HTTP requests at one’s router or firewall will suffice (both -of which are beyond the scope of this manual but easily searchable -with Google).
  • -

-

-

Securing your phpMyAdmin installation

-

The phpMyAdmin team tries hard to make the application secure, however there -are always ways to make your installation more secure:

-
    -
  • Follow our Security announcements and upgrade -phpMyAdmin whenever new vulnerability is published.

    -
  • -
  • Serve phpMyAdmin on HTTPS only. Preferably, you should use HSTS as well, so that -you’re protected from protocol downgrade attacks.

    -
  • -
  • Ensure your PHP setup follows recommendations for production sites, for example -display_errors -should be disabled.

    -
  • -
  • Remove the test directory from phpMyAdmin, unless you are developing and need a test suite.

    -
  • -
  • Remove the setup directory from phpMyAdmin, you will probably not -use it after the initial setup.

    -
  • -
  • Properly choose an authentication method - Cookie authentication mode -is probably the best choice for shared hosting.

    -
  • -
  • Deny access to auxiliary files in ./libraries/ or -./templates/ subfolders in your webserver configuration. -Such configuration prevents from possible path exposure and cross side -scripting vulnerabilities that might happen to be found in that code. For the -Apache webserver, this is often accomplished with a .htaccess file in -those directories.

    -
  • -
  • Deny access to temporary files, see $cfg['TempDir'] (if that -is placed inside your web root, see also Web server upload/save/import directories.

    -
  • -
  • It is generally a good idea to protect a public phpMyAdmin installation -against access by robots as they usually can not do anything good there. You -can do this using robots.txt file in the root of your webserver or limit -access by web server configuration, see 1.42 How can I prevent robots from accessing phpMyAdmin?.

    -
  • -
  • In case you don’t want all MySQL users to be able to access -phpMyAdmin, you can use $cfg['Servers'][$i]['AllowDeny']['rules'] to limit them -or $cfg['Servers'][$i]['AllowRoot'] to deny root user access.

    -
  • -
  • Enable Two-factor authentication for your account.

    -
  • -
  • Consider hiding phpMyAdmin behind an authentication proxy, so that -users need to authenticate prior to providing MySQL credentials -to phpMyAdmin. You can achieve this by configuring your web server to request -HTTP authentication. For example in Apache this can be done with:

    -
    AuthType Basic
    -AuthName "Restricted Access"
    -AuthUserFile /usr/share/phpmyadmin/passwd
    -Require valid-user
    -
    -
    -

    Once you have changed the configuration, you need to create a list of users which -can authenticate. This can be done using the htpasswd utility:

    -
    htpasswd -c /usr/share/phpmyadmin/passwd username
    -
    -
    -
  • -
  • If you are afraid of automated attacks, enabling Captcha by -$cfg['CaptchaLoginPublicKey'] and -$cfg['CaptchaLoginPrivateKey'] might be an option.

    -
  • -
  • Failed login attemps are logged to syslog (if available, see -$cfg['AuthLog']). This can allow using a tool such as -fail2ban to block brute-force attempts. Note that the log file used by syslog -is not the same as the Apache error or access log files.

    -
  • -
  • In case you’re running phpMyAdmin together with other PHP applications, it is -generally advised to use separate session storage for phpMyAdmin to avoid -possible session-based attacks against it. You can use -$cfg['SessionSavePath'] to achieve this.

    -

Using SSL for connection to database server

-

It is recommended to use SSL when connecting to remote database server. There -are several configuration options involved in the SSL setup:

-
-
$cfg['Servers'][$i]['ssl']
-
Defines whether to use SSL at all. If you enable only this, the connection -will be encrypted, but there is not authentication of the connection - you -can not verify that you are talking to the right server.
-
$cfg['Servers'][$i]['ssl_key'] and $cfg['Servers'][$i]['ssl_cert']
-
This is used for authentication of client to the server.
-
$cfg['Servers'][$i]['ssl_ca'] and $cfg['Servers'][$i]['ssl_ca_path']
-
The certificate authorities you trust for server certificates. -This is used to ensure that you are talking to a trusted server.
-
$cfg['Servers'][$i]['ssl_verify']
-
This configuration disables server certificate verification. Use with -caution.
-
- -
-
-

Known issues

-
-

Users with column-specific privileges are unable to “Browse”

-

If a user has only column-specific privileges on some (but not all) columns in a table, “Browse” -will fail with an error message.

-

As a workaround, a bookmarked query with the same name as the table can be created, this will -run when using the “Browse” link instead. Issue 11922.

-
-
-

Trouble logging back in after logging out using ‘http’ authentication

-

When using the ‘http’ auth_type, it can be impossible to log back in (when the logout comes -manually or after a period of inactivity). Issue 11898.
