We recommend the following setup for Apache -servers running in safe mode, to enable uploads of files while being -reasonably secure: - -* create a separate directory for uploads: :command:`mkdir /tmp/php` -* give ownership to the Apache server's user.group: :command:`chown - apache.apache /tmp/php` -* give proper permission: :command:`chmod 600 /tmp/php` -* put ``upload_tmp_dir = /tmp/php`` in :file:`php.ini` -* restart Apache - -.. _faq1_9: - -1.9 (withdrawn). ----------------- - -.. _faq1_10: - -1.10 I'm having troubles when uploading files with phpMyAdmin running on a secure server.

Please modify your column names to -align with current standards. - -.. _faq1_16: - -1.16 I cannot upload big dump files (memory, HTTP or timeout problems). ------------------------------------------------------------------------ - -Starting with version 2.7.0, the import engine has been re–written and -these problems should not occur. If possible, upgrade your phpMyAdmin -to the latest version to take advantage of the new import features. - -The first things to check (or ask your host provider to check) are the values -of ``max_execution_time``, ``upload_max_filesize``, ``memory_limit`` and -``post_max_size`` in the :file:`php.ini` configuration file. All of these -settings limit the maximum size of data that can be submitted and handled by -PHP. Please note that ``post_max_size`` needs to be larger than -``upload_max_filesize``. There exist several workarounds if your upload is too -big or your hosting provider is unwilling to change the settings: - -* Look at the :config:option:`$cfg['UploadDir']` feature. This allows one to upload a file to the server - via scp, FTP, or your favorite file transfer method. PhpMyAdmin is - then able to import the files from the temporary directory. More - information is available in the :ref:`config` of this document. -* Using a utility (such as `BigDump - `_) to split the files before - uploading. We cannot support this or any third party applications, but - are aware of users having success with it. -* If you have shell (command line) access, use MySQL to import the files - directly. You can do this by issuing the "source" command from within - MySQL: - - .. code-block:: mysql - - source filename.sql; - -.. _faq1_17: - -1.17 Which Database versions does phpMyAdmin support? ------------------------------------------------------ - -For `MySQL `_, versions 5.5 and newer are supported. -For older MySQL versions, our `Downloads `_ page offers older phpMyAdmin versions -(which may have become unsupported). - -For `MariaDB `_, versions 5.5 and newer are supported. - -.. _faq1_17a: - -1.17a I cannot connect to the MySQL server. It always returns the error message, "Client does not support authentication protocol requested by server; consider upgrading MySQL client" ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- - -You tried to access MySQL with an old MySQL client library. The -version of your MySQL client library can be checked in your phpinfo() -output. In general, it should have at least the same minor version as -your server - as mentioned in :ref:`faq1_17`. This problem is -generally caused by using MySQL version 4.1 or newer. MySQL changed -the authentication hash and your PHP is trying to use the old method. -The proper solution is to use the `mysqli extension -`_ with the proper client library to match -your MySQL installation. More -information (and several workarounds) are located in the `MySQL -Documentation `_. - -.. _faq1_18: - -1.18 (withdrawn). ------------------ - -.. _faq1_19: - -1.19 I can't run the "display relations" feature because the script seems not to know the font face I'm using! --------------------------------------------------------------------------------------------------------------- - -The :term:`TCPDF` library we're using for this feature requires some special -files to use font faces. Please refers to the `TCPDF manual -`_ to build these files. - -.. _faqmysql: - -1.20 I receive an error about missing mysqli and mysql extensions. ------------------------------------------------------------------- - -To connect to a MySQL server, PHP needs a set of MySQL functions -called "MySQL extension". This extension may be part of the PHP -distribution (compiled-in), otherwise it needs to be loaded -dynamically. Its name is probably *mysqli.so* or *php\_mysqli.dll*. -phpMyAdmin tried to load the extension but failed. Usually, the -problem is solved by installing a software package called "PHP-MySQL" -or something similar. - -There are currently two interfaces PHP provides as MySQL extensions - ``mysql`` -and ``mysqli``. The ``mysqli`` is tried first, because it's the best one. - -This problem can be also caused by wrong paths in the :file:`php.ini` or using -wrong :file:`php.ini`. - -Make sure that the extension files do exist in the folder which the -``extension_dir`` points to and that the corresponding lines in your -:file:`php.ini` are not commented out (you can use ``phpinfo()`` to check -current setup): - -.. code-block:: ini - - [PHP] - - ; Directory in which the loadable extensions (modules) reside. - extension_dir = "C:/Apache2/modules/php/ext" - -The :file:`php.ini` can be loaded from several locations (especially on -Windows), so please check you're updating the correct one. If using Apache, you -can tell it to use specific path for this file using ``PHPIniDir`` directive: - -.. code-block:: apache - - LoadFile "C:/php/php5ts.dll" - LoadModule php5_module "C:/php/php5apache2_2.dll" - - PHPIniDir "C:/PHP" - - AddType text/html .php - AddHandler application/x-httpd-php .php - - - -In some rare cases this problem can be also caused by other extensions loaded -in PHP which prevent MySQL extensions to be loaded. If anything else fails, you -can try commenting out extensions for other databses from :file:`php.ini`. - -.. _faq1_21: - -1.21 I am running the CGI version of PHP under Unix, and I cannot log in using cookie auth. -------------------------------------------------------------------------------------------- - -In :file:`php.ini`, set ``mysql.max_links`` higher than 1. - -.. _faq1_22: - -1.22 I don't see the "Location of text file" field, so I cannot upload. ------------------------------------------------------------------------ - -This is most likely because in :file:`php.ini`, your ``file_uploads`` -parameter is not set to "on". - -.. _faq1_23: - -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! ------------------------------------------------------------------------------------------------------------------------------- - -This happens because the MySQL directive ``lower_case_table_names`` -defaults to 1 (``ON``) in the Win32 version of MySQL. You can change -this behavior by simply changing the directive to 0 (``OFF``): Just -edit your ``my.ini`` file that should be located in your Windows -directory and add the following line to the group [mysqld]: - -.. code-block:: ini - - set-variable = lower_case_table_names=0 - -.. note:: - - Forcing this variable to 0 with --lower-case-table-names=0 on a - case-insensitive filesystem and access MyISAM tablenames using different - lettercases, index corruption may result. - -Next, save the file and restart the MySQL service. You can always -check the value of this directive using the query - -.. code-block:: mysql - - SHOW VARIABLES LIKE 'lower_case_table_names'; - -.. seealso:: `Identifier Case Sensitivity in the MySQL Reference Manual `_ - -.. _faq1_24: - -1.24 (withdrawn). ------------------ - -.. _faq1_25: - -1.25 I am running Apache with mod\_gzip-1.3.26.1a on Windows XP, and I get problems, such as undefined variables when I run a SQL query. ----------------------------------------------------------------------------------------------------------------------------------------- - -A tip from Jose Fandos: put a comment on the following two lines in -httpd.conf, like this: - -.. code-block:: apache - - # mod_gzip_item_include file \.php$ - # mod_gzip_item_include mime "application/x-httpd-php.*" - -as this version of mod\_gzip on Apache (Windows) has problems handling -PHP scripts. Of course you have to restart Apache. - -.. _faq1_26: - -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. ----------------------------------------------------------------------------------------------------------------------------------------- - -This is a permission problem. Right-click on the phpmyadmin folder and -choose properties. Under the tab Security, click on "Add" and select -the user "IUSR\_machine" from the list. Now set his permissions and it -should work. - -.. _faq1_27: - -1.27 I get empty page when I want to view huge page (eg. db\_structure.php with plenty of tables). --------------------------------------------------------------------------------------------------- - -This was caused by a `PHP bug `_ that occur when -GZIP output buffering is enabled. If you turn off it (by -:config:option:`$cfg['OBGzip']` in :file:`config.inc.php`), it should work. -This bug will has been fixed in PHP 5.0.0. - -.. _faq1_28: - -1.28 My MySQL server sometimes refuses queries and returns the message 'Errorcode: 13'. What does this mean? ------------------------------------------------------------------------------------------------------------- - -This can happen due to a MySQL bug when having database / table names -with upper case characters although ``lower_case_table_names`` is -set to 1. To fix this, turn off this directive, convert all database -and table names to lower case and turn it on again. Alternatively, -there's a bug-fix available starting with MySQL 3.23.56 / -4.0.11-gamma. - -.. _faq1_29: - -1.29 When I create a table or modify a column, I get an error and the columns are duplicated. ---------------------------------------------------------------------------------------------- - -It is possible to configure Apache in such a way that PHP has problems -interpreting .php files. - -The problems occur when two different (and conflicting) set of -directives are used: - -.. code-block:: apache - - SetOutputFilter PHP - SetInputFilter PHP - -and - -.. code-block:: apache - - AddType application/x-httpd-php .php - -In the case we saw, one set of directives was in -``/etc/httpd/conf/httpd.conf``, while the other set was in -``/etc/httpd/conf/addon-modules/php.conf``. The recommended way is -with ``AddType``, so just comment out the first set of lines and -restart Apache: - -.. code-block:: apache - - #SetOutputFilter PHP - #SetInputFilter PHP - -.. _faq1_30: - -1.30 I get the error "navigation.php: Missing hash". ----------------------------------------------------- - -This problem is known to happen when the server is running Turck -MMCache but upgrading MMCache to version 2.3.21 solves the problem. - -.. _faq1_31: - -1.31 Which PHP versions does phpMyAdmin support? ------------------------------------------------- - -Since release 4.5, phpMyAdmin supports only PHP 5.5 and newer. Since release -4.1 phpMyAdmin supports only PHP 5.3 and newer. For PHP 5.2 you can use 4.0.x -releases. - -PHP 7 is supported since phpMyAdmin 4.6, PHP 7.1 is supported since 4.6.5, -PHP 7.2 is supported since 4.7.4. - -HHVM is supported up to phpMyAdmin 4.8. - -Since release 5.0, phpMyAdmin supports only PHP 7.1 and newer. - -.. _faq1_32: - -1.32 Can I use HTTP authentication with IIS? --------------------------------------------- - -Yes. This procedure was tested with phpMyAdmin 2.6.1, PHP 4.3.9 in -:term:`ISAPI` mode under :term:`IIS` 5.1. - -#. In your :file:`php.ini` file, set ``cgi.rfc2616_headers = 0`` -#. In ``Web Site Properties -> File/Directory Security -> Anonymous - Access`` dialog box, check the ``Anonymous access`` checkbox and - uncheck any other checkboxes (i.e. uncheck ``Basic authentication``, - ``Integrated Windows authentication``, and ``Digest`` if it's - enabled.) Click ``OK``. -#. In ``Custom Errors``, select the range of ``401;1`` through ``401;5`` - and click the ``Set to Default`` button. - -.. seealso:: :rfc:`2616` - -.. _faq1_33: - -1.33 (withdrawn). ------------------ - -.. _faq1_34: - -1.34 Can I directly access a database or table pages? ------------------------------------------------------ - -Yes. Out of the box, you can use a :term:`URL` like -``http://server/phpMyAdmin/index.php?server=X&db=database&table=table&target=script``. -For ``server`` you can use the server number -which refers to the numeric host index (from ``$i``) in -:file:`config.inc.php`. The table and script parts are optional. - -If you want a URL like -``http://server/phpMyAdmin/database[/table][/script]``, you need to do some additional configuration. The following -lines apply only for the `Apache `_ web server. -First, make sure that you have enabled some features within the Apache global -configuration. You need ``Options SymLinksIfOwnerMatch`` and ``AllowOverride -FileInfo`` enabled for directory where phpMyAdmin is installed and you -need mod\_rewrite to be enabled. Then you just need to create the -following :term:`.htaccess` file in root folder of phpMyAdmin installation (don't -forget to change directory name inside of it): - -.. code-block:: apache - - RewriteEngine On - RewriteBase /path_to_phpMyAdmin - RewriteRule ^([a-zA-Z0-9_]+)/([a-zA-Z0-9_]+)/([a-z_]+\.php)$ index.php?db=$1&table=$2&target=$3 [R] - RewriteRule ^([a-zA-Z0-9_]+)/([a-z_]+\.php)$ index.php?db=$1&target=$2 [R] - RewriteRule ^([a-zA-Z0-9_]+)/([a-zA-Z0-9_]+)$ index.php?db=$1&table=$2 [R] - RewriteRule ^([a-zA-Z0-9_]+)$ index.php?db=$1 [R] - -.. seealso:: :ref:`faq4_8` - -.. _faq1_35: - -1.35 Can I use HTTP authentication with Apache CGI? ---------------------------------------------------- - -Yes. However you need to pass authentication variable to :term:`CGI` using -following rewrite rule: - -.. code-block:: apache - - RewriteEngine On - RewriteRule .* - [E=REMOTE_USER:%{HTTP:Authorization},L] - -.. _faq1_36: - -1.36 I get an error "500 Internal Server Error". ------------------------------------------------- - -There can be many explanations to this and a look at your server's -error log file might give a clue. - -.. _faq1_37: - -1.37 I run phpMyAdmin on cluster of different machines and password encryption in cookie auth doesn't work. ------------------------------------------------------------------------------------------------------------ - -If your cluster consist of different architectures, PHP code used for -encryption/decryption won't work correct. This is caused by use of -pack/unpack functions in code. Only solution is to use mcrypt -extension which works fine in this case. - -.. _faq1_38: - -1.38 Can I use phpMyAdmin on a server on which Suhosin is enabled? ------------------------------------------------------------------- - -Yes but the default configuration values of Suhosin are known to cause -problems with some operations, for example editing a table with many -columns and no :term:`primary key` or with textual :term:`primary key`. - -Suhosin configuration might lead to malfunction in some cases and it -can not be fully avoided as phpMyAdmin is kind of application which -needs to transfer big amounts of columns in single HTTP request, what -is something what Suhosin tries to prevent. Generally all -``suhosin.request.*``, ``suhosin.post.*`` and ``suhosin.get.*`` -directives can have negative effect on phpMyAdmin usability. You can -always find in your error logs which limit did cause dropping of -variable, so you can diagnose the problem and adjust matching -configuration variable. - -The default values for most Suhosin configuration options will work in -most scenarios, however you might want to adjust at least following -parameters: - -* `suhosin.request.max\_vars `_ should - be increased (eg. 2048) -* `suhosin.post.max\_vars `_ should be - increased (eg. 2048) -* `suhosin.request.max\_array\_index\_length `_ - should be increased (eg. 256) -* `suhosin.post.max\_array\_index\_length `_ - should be increased (eg. 256) -* `suhosin.request.max\_totalname\_length `_ - should be increased (eg. 8192) -* `suhosin.post.max\_totalname\_length `_ should be - increased (eg. 8192) -* `suhosin.get.max\_value\_length `_ - should be increased (eg. 1024) -* `suhosin.sql.bailout\_on\_error `_ - needs to be disabled (the default) -* `suhosin.log.\* `_ should not - include :term:`SQL`, otherwise you get big - slowdown -* `suhosin.sql.union `_ must be disabled (which is the default). -* `suhosin.sql.multiselect `_ must be disabled (which is the default). -* `suhosin.sql.comment `_ must be disabled (which is the default). - -To further improve security, we also recommend these modifications: - -* `suhosin.executor.include.max\_traversal `_ should be - enabled as a mitigation against local file inclusion attacks. We suggest - setting this to 2 as ``../`` is used with the ReCaptcha library. -* `suhosin.cookie.encrypt `_ should be enabled. -* `suhosin.executor.disable_emodifier `_ should be enabled. - -You can also disable the warning using the :config:option:`$cfg['SuhosinDisableWarning']`. - -.. _faq1_39: - -1.39 When I try to connect via https, I can log in, but then my connection is redirected back to http. What can cause this behavior? ------------------------------------------------------------------------------------------------------------------------------------- - -This is caused by the fact that PHP scripts have no knowledge that the site is -using https. Depending on used webserver, you should configure it to let PHP -know about URL and scheme used to access it. - -For example in Apache ensure that you have enabled ``SSLOptions`` and -``StdEnvVars`` in the configuration. - -.. seealso:: - -.. _faq1_40: - -1.40 When accessing phpMyAdmin via an Apache reverse proxy, cookie login does not work. ---------------------------------------------------------------------------------------- - -To be able to use cookie auth Apache must know that it has to rewrite -the set-cookie headers. Example from the Apache 2.2 documentation: - -.. code-block:: apache - - ProxyPass /mirror/foo/ http://backend.example.com/ - ProxyPassReverse /mirror/foo/ http://backend.example.com/ - ProxyPassReverseCookieDomain backend.example.com public.example.com - ProxyPassReverseCookiePath / /mirror/foo/ - -Note: if the backend url looks like ``http://server/~user/phpmyadmin``, the -tilde (~) must be url encoded as %7E in the ProxyPassReverse\* lines. -This is not specific to phpmyadmin, it's just the behavior of Apache. - -.. code-block:: apache - - ProxyPass /mirror/foo/ http://backend.example.com/~user/phpmyadmin - ProxyPassReverse /mirror/foo/ http://backend.example.com/%7Euser/phpmyadmin - ProxyPassReverseCookiePath /%7Euser/phpmyadmin /mirror/foo - -.. seealso:: , :config:option:`$cfg['PmaAbsoluteUri']` - -.. _faq1_41: - -1.41 When I view a database and ask to see its privileges, I get an error about an unknown column. --------------------------------------------------------------------------------------------------- - -The MySQL server's privilege tables are not up to date, you need to -run the :command:`mysql_upgrade` command on the server. - -.. _faq1_42: - -1.42 How can I prevent robots from accessing phpMyAdmin? --------------------------------------------------------- - -You can add various rules to :term:`.htaccess` to filter access based on user agent -field.

To do this, -connect to your server and go to the MySQL bin directory. In this directory -there should be a file named *mysqladmin*. Type ``./mysqladmin variables``, and -this should give you a bunch of info about your MySQL server, including the -socket (*/tmp/mysql.sock*, for example). You can also ask your ISP for the -connection info or, if you're hosting your own, connect from the 'mysql' -command-line client and type 'status' to get the connection type and socket or -port number. - -Then, you need to tell PHP to use this socket. You can do this for all PHP in -the :file:`php.ini` or for phpMyAdmin only in the :file:`config.inc.php`. For -example: :config:option:`$cfg['Servers'][$i]['socket']` Please also make sure -that the permissions of this file allow to be readable by your webserver. - -On my RedHat-Box the socket of MySQL is */var/lib/mysql/mysql.sock*. -In your :file:`php.ini` you will find a line - -.. code-block:: ini - - mysql.default_socket = /tmp/mysql.sock - -change it to - -.. code-block:: ini - - mysql.default_socket = /var/lib/mysql/mysql.sock - -Then restart apache and it will work. - -Have also a look at the `corresponding section of the MySQL -documentation `_. - -.. _faq2_4: - -2.4 Nothing is displayed by my browser when I try to run phpMyAdmin, what can I do? ------------------------------------------------------------------------------------ - -Try to set the :config:option:`$cfg['OBGzip']` directive to ``false`` in the phpMyAdmin configuration -file. It helps sometime. Also have a look at your PHP version number: -if it contains "b" or "alpha" it means you're running a testing -version of PHP. That's not a so good idea, please upgrade to a plain -revision. - -.. _faq2_5: - -2.5 Each time I want to insert or change a row or drop a database or a table, an error 404 (page not found) is displayed or, with HTTP or cookie authentication, I'm asked to log in again. What's wrong? ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- - -Check your webserver setup if it correctly fills in either PHP_SELF or REQUEST_URI variables. - -If you are running phpMyAdmin behind reverse proxy, please set the -:config:option:`$cfg['PmaAbsoluteUri']` directive in the phpMyAdmin -configuration file to match your setup. - -.. _faq2_6: - -2.6 I get an "Access denied for user: 'root@localhost' (Using password: YES)"-error when trying to access a MySQL-Server on a host which is port-forwarded for my localhost. ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------- - -When you are using a port on your localhost, which you redirect via -port-forwarding to another host, MySQL is not resolving the localhost -as expected. Erik Wasser explains: The solution is: if your host is -"localhost" MySQL (the command line tool :command:`mysql` as well) always -tries to use the socket connection for speeding up things. And that -doesn't work in this configuration with port forwarding. If you enter -"127.0.0.1" as hostname, everything is right and MySQL uses the -:term:`TCP` connection. - -.. _faqthemes: - -2.7 Using and creating themes ------------------------------ - -See :ref:`themes`. - -.. _faqmissingparameters: - -2.8 I get "Missing parameters" errors, what can I do? ------------------------------------------------------ - -Here are a few points to check: - -* In :file:`config.inc.php`, try to leave the :config:option:`$cfg['PmaAbsoluteUri']` directive empty. See also - :ref:`faq4_7`. -* Maybe you have a broken PHP installation or you need to upgrade your - Zend Optimizer. See . -* If you are using Hardened PHP with the ini directive - ``varfilter.max_request_variables`` set to the default (200) or - another low value, you could get this error if your table has a high - number of columns. Adjust this setting accordingly. (Thanks to Klaus - Dorninger for the hint). -* In the :file:`php.ini` directive ``arg_separator.input``, a value of ";" - will cause this error. Replace it with "&;". -* If you are using `Suhosin `_, you - might want to increase `request limits `_. -* The directory specified in the :file:`php.ini` directive - ``session.save_path`` does not exist or is read-only (this can be caused - by `bug in the PHP installer `_). - -.. _faq2_9: - -2.9 Seeing an upload progress bar ---------------------------------- - -To be able to see a progress bar during your uploads, your server must -have the `APC `_ extension, the -`uploadprogress `_ one, or -you must be running PHP 5.4.0 or higher. Moreover, the JSON extension -has to be enabled in your PHP. - -If using APC, you must set ``apc.rfc1867`` to ``on`` in your :file:`php.ini`. - -If using PHP 5.4.0 or higher, you must set -``session.upload_progress.enabled`` to ``1`` in your :file:`php.ini`.

To bypass this problem: just close all the opened browser -windows and then go back to phpMyAdmin. You should be able to log in -again. - -.. _faq3_2: - -3.2 When dumping a large table in compressed mode, I get a memory limit error or a time limit error. ----------------------------------------------------------------------------------------------------- - -Compressed dumps are built in memory and because of this are limited -to php's memory limit. For gzip/bzip2 exports this can be overcome -since 2.5.4 using :config:option:`$cfg['CompressOnFly']` (enabled by default). -zip exports can not be handled this way, so if you need zip files for larger -dump, you have to use another way. - -.. _faq3_3: - -3.3 With InnoDB tables, I lose foreign key relationships when I rename a table or a column. -------------------------------------------------------------------------------------------- - -This is an InnoDB bug, see . - -.. _faq3_4: - -3.4 I am unable to import dumps I created with the mysqldump tool bundled with the MySQL server distribution. -------------------------------------------------------------------------------------------------------------- - -The problem is that older versions of ``mysqldump`` created invalid -comments like this: - -.. code-block:: mysql - - -- MySQL dump 8.22 - -- - -- Host: localhost Database: database - --------------------------------------------------------- - -- Server version 3.23.54 - -The invalid part of the code is the horizontal line made of dashes -that appears once in every dump created with mysqldump.

How can this be fixed? ------------------------------------------------------------------------------------------------------------------------------------------------------------ - -Your table neither have a :term:`primary key` nor an :term:`unique key`, so we must -use a long expression to identify this row. This causes problems to -parse\_url function. The workaround is to create a :term:`primary key` -or :term:`unique key`. - -.. _faq3_8: - -3.8 I cannot use (clickable) HTML-forms in columns where I put a MIME-Transformation onto! ------------------------------------------------------------------------------------------- - -Due to a surrounding form-container (for multi-row delete checkboxes), -no nested forms can be put inside the table where phpMyAdmin displays -the results. You can, however, use any form inside of a table if keep -the parent form-container with the target to tbl\_row\_delete.php and -just put your own input-elements inside.

For the -time being, you will have to break apart :term:`CSV` files containing multiple -tables. - -.. _faq3_19: - -3.19 When I import a file and have phpMyAdmin determine the appropriate data structure it only uses int, decimal, and varchar types. ------------------------------------------------------------------------------------------------------------------------------------- - -Currently, the import type-detection system can only assign these -MySQL types to columns. In future, more will likely be added but for -the time being you will have to edit the structure to your liking -post-import. Also, you should note the fact that phpMyAdmin will use -the size of the largest item in any given column as the column size -for the appropriate type. If you know you will be adding larger items -to that column then you should manually adjust the column sizes -accordingly. This is done for the sake of efficiency. - -.. _faq3_20: - -3.20 After upgrading, some bookmarks are gone or their content cannot be shown. -------------------------------------------------------------------------------- - -At some point, the character set used to store bookmark content has changed. -It's better to recreate your bookmark from the newer phpMyAdmin version. - -.. _faq3_21: - -3.21 I am unable to log in with a username containing unicode characters such as á. ------------------------------------------------------------------------------------ - -This can happen if MySQL server is not configured to use utf-8 as default -charset.

Can I setup one central copy of phpMyAdmin or do I need to install it for each customer? --------------------------------------------------------------------------------------------------------- - -Since version 2.0.3, you can setup a central copy of phpMyAdmin for all your -users. The development of this feature was kindly sponsored by NetCologne GmbH. -This requires a properly setup MySQL user management and phpMyAdmin -:term:`HTTP` or cookie authentication. - -.. seealso:: :ref:`authentication_modes` - -.. _faq4_2: - -4.2 What's the preferred way of making phpMyAdmin secure against evil access? ------------------------------------------------------------------------------ - -This depends on your system. If you're running a server which cannot be -accessed by other people, it's sufficient to use the directory protection -bundled with your webserver (with Apache you can use :term:`.htaccess` files, -for example). If other people have telnet access to your server, you should use -phpMyAdmin's :term:`HTTP` or cookie authentication features. - -Suggestions: - -* Your :file:`config.inc.php` file should be ``chmod 660``. -* All your phpMyAdmin files should be chown -R phpmy.apache, where phpmy - is a user whose password is only known to you, and apache is the group - under which Apache runs. -* Follow security recommendations for PHP and your webserver. - -.. _faq4_3: - -4.3 I get errors about not being able to include a file in */lang* or in */libraries*. --------------------------------------------------------------------------------------- - -Check :file:`php.ini`, or ask your sysadmin to check it. The -``include_path`` must contain "." somewhere in it, and -``open_basedir``, if used, must contain "." and "./lang" to allow -normal operation of phpMyAdmin. - -.. _faq4_4: - -4.4 phpMyAdmin always gives "Access denied" when using HTTP authentication. ---------------------------------------------------------------------------- - -This could happen for several reasons: - -* :config:option:`$cfg['Servers'][$i]['controluser']` and/or :config:option:`$cfg['Servers'][$i]['controlpass']` are wrong. -* The username/password you specify in the login dialog are invalid. -* You have already setup a security mechanism for the phpMyAdmin- - directory, eg. a :term:`.htaccess` file. This would interfere with phpMyAdmin's - authentication, so remove it. - -.. _faq4_5: - -4.5 Is it possible to let users create their own databases? ------------------------------------------------------------ - -Starting with 2.2.5, in the user management page, you can enter a -wildcard database name for a user (for example "joe%"), and put the -privileges you want. For example, adding ``SELECT, INSERT, UPDATE, -DELETE, CREATE, DROP, INDEX, ALTER`` would let a user create/manage -his/her database(s). - -.. _faq4_6: - -4.6 How can I use the Host-based authentication additions? ----------------------------------------------------------- - -If you have existing rules from an old :term:`.htaccess` file, you can take them and -add a username between the ``'deny'``/``'allow'`` and ``'from'`` -strings. Using the username wildcard of ``'%'`` would be a major -benefit here if your installation is suited to using it. Then you can -just add those updated lines into the -:config:option:`$cfg['Servers'][$i]['AllowDeny']['rules']` array. - -If you want a pre-made sample, you can try this fragment.
