Connect to external server by using phpMyAdmin

问题:

I have phpMyAdmin installed on my local machine. How can I make it connect to an external server?

回答1:

In the config file, change the "host" variable to point to the external server. The config file is called config.inc.php and it will be in the main phpMyAdmin folder. There should be a line like this:

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

Just change localhost to your server's IP address.

Note: you may have to configure the external server to allow remote connections, but I've done this several times on shared hosting so it should be fine.

回答2:

To set up an external DB and still use your local DB, you need to edit the config.inc.php file:

On Ubuntu: sudo gedit /etc/phpmyadmin/config.inc.php

The file is roughly set up like this:

if (!empty($dbname)) {

    //Your local db setup

     $i++;
}

What you need to do is duplicate the "your local db setup" by copying and pasting it outside of the IF statement I've shown in the code below, and change the host to you external IP. Mine for example is:

$cfg['Servers'][$i]['host'] = '10.10.1.90:23306';

You can leave the defaults (unless you know you need to change them)

Save and refresh your PHPMYADMIN login page and a new dropdown should appear. You should be good to go.

EDIT: if you want to give the server a name to select at login page, rather than having just the IP address to select, add this to the server setup:

$cfg['Servers'][$i]['verbose'] = 'Name to show when selecting your server'; 

It's good if you have multiple server configs.

at version 4.0 or above, we need to create one 'config.inc.php' or rename the 'config.sample.inc.php' to 'config.inc.php';

In my case, I also work with one mysql server for each environment (dev and production):

/* others code*/  
$whoIam = gethostname();
switch($whoIam) {
    case 'devHost':
        $cfg['Servers'][$i]['host'] = 'localhost';
        break;
    case 'MasterServer':
        $cfg['Servers'][$i]['host'] = 'masterMysqlServer';
        break;
} /* others code*/

using PhpMyAdmin version 4.5.4.1deb2ubuntu2, you can set the variables in /etc/phpmyadmin/config-db.php

so set $dbserver to your server name, e.g. $dbserver='mysql.example.com';

<?php
##
## database access settings in php format
## automatically generated from /etc/dbconfig-common/phpmyadmin.conf
## by /usr/sbin/dbconfig-generate-include
##
## by default this file is managed via ucf, so you shouldn't have to
## worry about manual changes being silently discarded.  *however*,
## you'll probably also want to edit the configuration file mentioned
## above too.
##
$dbuser='phpmyadmin';
$dbpass='P@55w0rd';
$basepath='';
$dbname='phpmyadmin';
$dbserver='localhost';
$dbport='';
$dbtype='mysql';

You can use the phpmyadmin setup page (./phpmyadmin/setup) to generate a new config file (config.inc.php) for you. This file is found at the root of the phpMyAdmin directory.

Just create the config folder as prompted in setup page, add your servers, then click the 'Save' button. This will create a new config file in the config folder you just created.

You now have only to move the config.inc.php file to the main phpMyAdmin folder, or just copy the lines concerning the servers if you got some old configuration done already you'd like to keep.

Don't forget to delete the config folder afterwards.

in the config.inc.php, remove all lines with "$cfg['Servers']" , and keep ONLY the "$cfg['Servers'][$i]['host']"
