PhpMyAdmin

zh-CN:PhpMyAdmin

phpMyAdmin is a web-based tool to help manage MySQL databases using an Apache/PHP frontend. It requires a working LAMP setup.

Installation

Install the phpmyadmin and php-mcrypt packages:

# pacman -S phpmyadmin php-mcrypt

Configuration

Ensure you do not have an older copy of phpMyAdmin.

# rm -r /srv/http/phpMyAdmin

Copy the example configuration file to your httpd configuration directory.

# cp /etc/webapps/phpmyadmin/apache.example.conf /etc/httpd/conf/extra/httpd-phpmyadmin.conf

Add the following lines to /etc/httpd/conf/httpd.conf:

# phpMyAdmin configuration
Include conf/extra/httpd-phpmyadmin.conf

Adjust access rights

To allow access from any host, edit /etc/webapps/phpmyadmin/.htaccess and change deny from all into

allow from all

Alternatively, you can restrict access to localhost and your local network only. Replace 192.168.1.0/24 with your network's IP block.

deny from all
allow from localhost
allow from 127.0.0.1
allow from ::1
allow from 192.168.1.0/24

Note: The ::1 is required when using IPv6. Otherwise you might get an error similar to "Error 403 - Access forbidden!" when you attempt to access your phpMyAdmin installation.

Review apache phpmyadmin configuration

Your /etc/httpd/conf/extra/httpd-phpmyadmin.conf should have the following information:

        Alias /phpmyadmin "/usr/share/webapps/phpMyAdmin"
        <Directory "/usr/share/webapps/phpMyAdmin">
                AllowOverride All
                Options FollowSymlinks
                Order allow,deny
                Allow from all
                php_admin_value open_basedir "/srv/:/tmp/:/usr/share/webapps/:/etc/webapps:/usr/share/pear/"
        </Directory>

You need the mysqli and mcrypt (if you want phpMyAdmin internal authentication) modules, so uncomment the following in /etc/php/php.ini:

extension=mysqli.so
extension=mcrypt.so

Restart httpd.

Add blowfish_secret passphrase

If you see the following error message at the bottom of the page when you first log in to /phpmyadmin (using a previously setup MySQL username and password) :

ERROR: The configuration file now needs a secret passphrase (blowfish_secret)

You need to add a blowfish password to the phpMyAdmin's config file. Edit /etc/webapps/phpmyadmin/config.inc.php and insert a random blowfish "password" in the line

$cfg['blowfish_secret'] = ; /* YOU MUST FILL IN THIS FOR COOKIE AUTH! */

Go here to get a nicely generated blowfish_secret and paste it between the marks. It should now look something like this:

$cfg['blowfish_secret'] = 'qtdRoGmbc9{8IZr323xYcSN]0s)r$9b_JUnb{~Xz'; /* YOU MUST FILL IN THIS FOR COOKIE AUTH! */

The error should go away if you refresh the phpmyadmin page.

Enabling Configuration Storage (optional)

Now that the basic database server has been setup, it is functional, however by default, extra options such as table linking, change tracking, PDF creation, and bookmarking queries are disabled. You will see a message at the bottom of the main phpMyAdmin page, "The phpMyAdmin configuration storage is not completely configured, some extended features have been deactivated. To find out why...", This section addresses how to to enable these extra features.

Note: This example assumes you want to use the username pma as the controluser, and pmapass as the controlpass. These should be changed (the very least, you should change the password!) to something more secure.

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

// $cfg['Servers'][$i]['controluser'] = 'pma';
// $cfg['Servers'][$i]['controlpass'] = 'pmapass';

You will need this information later, so keep it in mind.

Beneath the controluser setup section, uncomment these lines:

/* 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]['tracking'] = 'pma_tracking';
// $cfg['Servers'][$i]['designer_coords'] = 'pma_designer_coords';
// $cfg['Servers'][$i]['userconfig'] = 'pma_userconfig';
// $cfg['Servers'][$i]['recent'] = 'pma_recent';

Next, create the user with the above details. Don't set any permissions for it just yet.

Note: If you can't login to phpmyadmin, make sure that your mysql server is started.

creating phpMyAdmin database

Using the phpMyAdmin web interface: Import /usr/share/webapps/phpMyAdmin/examples/create_tables.sql from phpMyAdmin -> Import. or Using command line: mysql -u root -p < /usr/share/webapps/phpMyAdmin/examples/create_tables.sql.

creating phpMyAdmin database user

Now to apply the permissions to your controluser, in the SQL tab, 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 to take advantage of the bookmark and relation features, you will also need to give pma some additional permissions:

Note: as long as you did not change the value of $cfg['Servers'][$i]['pmadb'] in /etc/webapps/phpmyadmin/config.inc.php, then <pma_db> should be phpmyadmin

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

Log out, and back in to ensure the new features are activated. The message at the bottom of the main screen should now be gone.

Accessing your phpMyAdmin installation

Finally your phpmyadmin installation is complete. Before you start using it you need to restart httpd (Apache)

You can access your phpmyadmin installation using the following url:

http://localhost/phpmyadmin/

If you want to access it using http://localhost/phpmyadmin, open '/etc/httpd/conf/extra/httpd-phpmyadmin.conf' and change:

Alias /phpmyadmin/ "/usr/share/webapps/phpMyAdmin/"

to

Alias /phpmyadmin "/usr/share/webapps/phpMyAdmin"

You should also read this thread.

If you get the error "#2002 - The server is not responding (or the local MySQL server's socket is not correctly configured)" then you might want to change "localhost" in /etc/webapps/phpmyadmin/config.inc.php to your hostname:

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

If you would like to use phpmyadmin setup script by calling http://localhost/phpmyadmin/setup you will need to create a config directory that's writeable by the httpd in the /usr/share/webapps/phpmyadmin as follows:

cd /usr/share/webapps/phpMyAdmin
mkdir config
chgrp http config
chmod g+w config

Lighttpd Configuration

Configurating 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 )

Update open_basedir in /etc/php/php.ini and add "/usr/share/webapps/".

 open_basedir = /srv/http/:/home/:/tmp/:/usr/share/pear/:/usr/share/webapps/:/etc/webapps/

Restart Lighttpd and go to [1].

Nginx Configuration

Configurating Nginx is similar to Apache (and Lighttpd, for that matter). Make sure Nginx is setup to serve PHP files (see Nginx).

You can setup a sub domain (or domain) with a server block like so (if using php-fpm):

 server {
         server_name     phpmyadmin.<domain.tld>;
 
         root    /usr/share/webapps/phpMyAdmin;
         index   index.php;
 
         location ~ \.php$ {
                 try_files      $uri =404;
                 fastcgi_pass   unix:/var/run/php-fpm/php-fpm.sock;
                 fastcgi_index  index.php;
                 include        fastcgi.conf;
         }
 }

To access this url on your localhost, you can simply add an entry in /etc/hosts:

 127.0.0.1	phpmyadmin.<domain.tld>

You need to update PHP's open_basedir option to add the appropriate directories. Either in /etc/php/php.ini:

 open_basedir = /srv/http/:/home/:/tmp/:/usr/share/pear/:/usr/share/webapps/:/etc/webapps/

Or if running php-fpm with a separate entry for phpmyadmin, you can overwrite this value in your pool definition (in /etc/php/fpm.d/<pool file>):

 php_admin_value[open_basedir] = /tmp/:/usr/share/webapps/:/etc/webapps/

If the above doesn't fix it try adding the following to your NGINX Configuration below the other fastcgi_param (I think its something to do with the Suhosin-Patch)

 fastcgi_param  PHP_ADMIN_VALUE  open_basedir="/srv/http/:/home/:/tmp/:/usr/share/pear/:/usr/share/webapps/:/etc/webapps/";

While you can enter anything for the blowfish password, you may want to choose a randomly generated string of characters (most likely for security reasons). Here's a handy tool that will do that for you on the web[2].

When using SSL, you might run into the problem that the links on the pages generated by phpMyAdmin incorrectly start with "http" instead of "https" which may cause errors. To fix this, you can add the following fcgi_param to your SSL-enabled server section (in addition to your usual fastcgi params):

 fastcgi_param HTTPS on;

Other (Older) information

This page holds a sample 'config.inc.php' file that you can place in the main phpMyAdmin directory so that it immediately starts working

Things you should do first

Create a 'controluser', so that phpmyadmin can read from the main mysql database.

mysql -u root -p YOURROOTPASSWORD
mysql> grant usage on mysql.* to controluser@localhost identified by 'CONTROLPASS';

Where is phpmyadmin

in phpmyadmin 3.2.2-3 the file is missing /srv/http/ create this symlik

ln -s /usr/share/webapps/phpMyAdmin/ /srv/http/phpmyadmin

Things you should change

controluser is set to controluser
controlpass is set to password
verbose is set to name_of_server
