phpMyAdmin is an open source tool used for the administration of MySQL. In addition to offering the capability to perform administration tasks such as creating, editing, or deleting databases, and managing users and permissions, phpMyAdmin provides a graphical user interface to do all of these tasks and more.

Pre-Flight Check

These instructions are intended specifically for installing phpMyAdmin on CentOS 7.
I’ll be working from a Liquid Web Self Managed CentOS 7 server, and I’ll be logged in as root.
A LAMP stack, meaning Linux, Apache, MySQL and PHP, must be installed on your server. If you’re working from a Liquid Web Core Managed CentOS server, then the LAMP stack is already installed!

Step 1: Add the EPEL Repository

phpMyAdmin is part of Extra Packages for Enterprise Linux (EPEL), which is a community repository of non-standard packages for the RHEL distribution. First, we’ll install the EPEL repository:

rpm -iUvh http://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm

Step 2: Install phpMyAdmin

First, you’ll follow a simple best practice: ensuring the list of available packages is up to date before installing anything new.

yum -y update

Then it’s a matter of just running one command for installation via apt-get:

yum -y install phpmyadmin

Step 3: Find Your IP Address

Find your IP address with any of the following sites:

Step 4: Basic Configuration for phpMyAdmin

To secure phpMyAdmin we should lock down access to a specific IP address. When the phpMyAdmin package is installed, an Apache Virtual Host file is added to configure web access. Let’s edit that file:

vim /etc/httpd/conf.d/phpMyAdmin.conf

For a refresher on editing files with vim see: New User Tutorial: Overview of the Vim Text Editor

By default, the configuration for phpMyAdmin only allows access from the server on which it is installed. Find the following sections and change each IP address to the one you found in Step 3, or another IP address that will be connecting to phpMyAdmin remotely:

Require ip 127.0.0.1

Allow from 127.0.0.1

Require ip 127.0.0.1

Allow from 127.0.0.1

Then exit and save the file with the command :wq .

Restart Apache:

systemctl restart httpd

Verify that phpMyAdmin is working by visiting http://the_IP_of_your_server/phpmyadmin. For example: http://1.2.3.4/phpmyadmin
