phpMyAdmin is a web-based tool to help manage MySQL databases using an Apache/PHP frontend.

Installation

Install the phpmyadmin package.

Running

PHP

Make sure the PHP mysql extension(s) have been enabled.

Optionally you can enable extension=bz2 and extension=zip for compression support.

Note: If open_basedir has been set, make sure to include /etc/webapps to open_basedir in /etc/php/php.ini.

Apache

Set up Apache to use PHP as outlined in the Apache HTTP Server#PHP article.

Create the Apache configuration file:

/etc/httpd/conf/extra/phpmyadmin.conf
Alias /phpmyadmin "/usr/share/webapps/phpMyAdmin"
<Directory "/usr/share/webapps/phpMyAdmin">
    DirectoryIndex index.php
    AllowOverride All
    Options FollowSymlinks
    Require all granted
</Directory>

And include it in /etc/httpd/conf/httpd.conf:

# phpMyAdmin configuration
Include conf/extra/phpmyadmin.conf
Note: By default, everyone who can reach the Apache Web Server can see the phpMyAdmin login page under this URL. To change this, edit /etc/httpd/conf/extra/phpmyadmin.conf to your liking. For example, if you only want to be able to access it from the same machine, replace Require all granted by Require local. Beware that this will disallow connecting to PhpMyAdmin on a remote server. If you still want to access PhpMyAdmin on a remote server securely, you might want to consider setting up a Secure Shell#Encrypted SOCKS tunnel.

Lighttpd

Configuring Lighttpd is similar to Apache. Make sure Lighttpd is setup to serve PHP files (see Lighttpd).

Make an alias for phpmyadmin in your Lighttpd config.

 alias.url = ( "/phpmyadmin" => "/usr/share/webapps/phpMyAdmin/")

Then enable mod_alias, mod_fastcgi and mod_cgi in your config ( server.modules section )

Restart Lighttpd and go to [1].

Nginx

Make sure to set up nginx#FastCGI.

Subdomain

Set up a separate configuration file for PHP as shown in nginx#PHP configuration file and use a server block such as:

server {
    server_name     phpmyadmin.<domain.tld>;
    root    /usr/share/webapps/phpMyAdmin;
    index   index.php;
    include php.conf;
}

Subdirectory using location

This will allow access to PhpMyAdmin as in https://domain.tld/phpMyAdmin:

/etc/nginx/sites-available/domain.tld
location /phpMyAdmin {
   server_name domain.tld;
   listen 443 ssl http2;
   root /srv/http/domain.tld;
   index index.php;  
  
   location / {
      try_files $uri $uri/ =404;
   }

   # Deny static files
   location ~ ^/phpMyAdmin/(README|LICENSE|ChangeLog|DCO)$ {
      deny all;
   }

   # Deny .md files
   location ~ ^/phpMyAdmin/(.+\.md)$ {
      deny all;
   }

   # Deny setup directories
   location ~ ^/phpMyAdmin/(doc|sql|setup)/ {
      deny all;
   }

   #FastCGI config for phpMyAdmin
   location ~ /phpMyAdmin/(.+\.php)$ {
      fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
      fastcgi_pass   unix:/run/php-fpm/php-fpm.sock;
      fastcgi_index  index.php;
      include        fastcgi.conf;
   }
}

Configuration

The main configuration file is located at /etc/webapps/phpmyadmin/config.inc.php.

If the MySQL server is not on localhost, append the following line:

$cfg['Servers'][$i]['host'] = 'localhost';

Using setup script

To allow the usage of the phpMyAdmin setup script (e.g. http://localhost/phpmyadmin/setup), make sure /usr/share/webapps/phpMyAdmin is writable for the http user:

# mkdir /usr/share/webapps/phpMyAdmin/config
# chown http:http /usr/share/webapps/phpMyAdmin/config
# chmod 750 /usr/share/webapps/phpMyAdmin/config

Add blowfish_secret passphrase

It is required to enter an unique string (32 characters are recommended) to fully use the blowfish algorithm used by phpMyAmdin, thus preventing the message ERROR: The configuration file now needs a secret passphrase (blowfish_secret):

/etc/webapps/phpmyadmin/config.inc.php
$cfg['blowfish_secret'] = '...';

Enabling Configuration Storage

Extra options such as table linking, change tracking, PDF creation, and bookmarking queries are disabled by default, displaying The phpMyAdmin configuration storage is not completely configured, some extended features have been deactivated. on the homepage.

Note: This example assumes you want to use the default username pma as the controluser, and pmapass as the controlpass.

In /etc/webapps/phpmyadmin/config.inc.php, uncomment (remove the leading "//"s), and change them to your desired credentials if needed:

/etc/webapps/phpmyadmin/config.inc.php
/* User used to manipulate with storage */
// $cfg['Servers'][$i]['controlhost'] = 'my-host';
// $cfg['Servers'][$i]['controlport'] = '3306';
$cfg['Servers'][$i]['controluser'] = 'pma';
$cfg['Servers'][$i]['controlpass'] = 'pmapass';

/* Storage database and tables */
$cfg['Servers'][$i]['pmadb'] = 'phpmyadmin';
$cfg['Servers'][$i]['bookmarktable'] = 'pma__bookmark';
$cfg['Servers'][$i]['relation'] = 'pma__relation';
$cfg['Servers'][$i]['table_info'] = 'pma__table_info';
$cfg['Servers'][$i]['table_coords'] = 'pma__table_coords';
$cfg['Servers'][$i]['pdf_pages'] = 'pma__pdf_pages';
$cfg['Servers'][$i]['column_info'] = 'pma__column_info';
$cfg['Servers'][$i]['history'] = 'pma__history';
$cfg['Servers'][$i]['table_uiprefs'] = 'pma__table_uiprefs';
$cfg['Servers'][$i]['tracking'] = 'pma__tracking';
$cfg['Servers'][$i]['userconfig'] = 'pma__userconfig';
$cfg['Servers'][$i]['recent'] = 'pma__recent';
$cfg['Servers'][$i]['favorite'] = 'pma__favorite';
$cfg['Servers'][$i]['users'] = 'pma__users';
$cfg['Servers'][$i]['usergroups'] = 'pma__usergroups';
$cfg['Servers'][$i]['navigationhiding'] = 'pma__navigationhiding';
$cfg['Servers'][$i]['savedsearches'] = 'pma__savedsearches';
$cfg['Servers'][$i]['central_columns'] = 'pma__central_columns';
$cfg['Servers'][$i]['designer_settings'] = 'pma__designer_settings';
$cfg['Servers'][$i]['export_templates'] = 'pma__export_templates';
Setup database

Two options are available to create the required tables:

  • Import /usr/share/webapps/phpMyAdmin/sql/create_tables.sql by using PhpMyAdmin.
  • Execute mysql -u root -p < /usr/share/webapps/phpMyAdmin/sql/create_tables.sql in the command line.
Setup database user

To apply the required permissions for controluser, execute the following query:

Note: Make sure to replace all instances of pma and pmapass to the values set in config.inc.php. If you are setting this up for a remote database, then you must also change localhost to the proper host.
GRANT USAGE ON mysql.* TO 'pma'@'localhost' IDENTIFIED BY 'pmapass';
GRANT SELECT (
    Host, User, Select_priv, Insert_priv, Update_priv, Delete_priv,
    Create_priv, Drop_priv, Reload_priv, Shutdown_priv, Process_priv,
    File_priv, Grant_priv, References_priv, Index_priv, Alter_priv,
    Show_db_priv, Super_priv, Create_tmp_table_priv, Lock_tables_priv,
    Execute_priv, Repl_slave_priv, Repl_client_priv
    ) ON mysql.user TO 'pma'@'localhost';
GRANT SELECT ON mysql.db TO 'pma'@'localhost';
GRANT SELECT ON mysql.host TO 'pma'@'localhost';
GRANT SELECT (Host, Db, User, Table_name, Table_priv, Column_priv)
    ON mysql.tables_priv TO 'pma'@'localhost';

In order use the bookmark and relation features, set the following permissions:

GRANT SELECT, INSERT, UPDATE, DELETE ON <pma_db>.* TO 'pma'@'localhost';

Re-login to ensure the new features are activated.

Enabling templates catching

Create the tmp directory:

# mkdir /usr/share/webapps/phpMyAdmin/tmp

Set read/write permissions for the http user:

# chmod 750 /usr/share/webapps/phpMyAdmin/tmp
# chown http:http /usr/share/webapps/phpMyAdmin/tmp

Refresh PhpMyAdmin to apply changes.
