Installing phpmyadmin and PHP 5.2.* on a Centos 5.2 Server (updated)

February 17, 2009

So I spent the better part of last night (12-3:30am) trying to figure out just exactly how to get phpmyadmin installed on my Centos 5.2 Server. Now, I’m no dummy when it comes to linux, package management etc… But this was a task which apparently many other people have had trouble with. I finally gave up on it and went to bed, woke up this morning and went back to it… At which point I actually figured everything out and now have PHP 5.2.8 installed working with phpmyadmin 3.1.2 (which to day, all the most recent stuff) using mysql-server 5.1.31.

So here’s how I did it: Apparently the repositories that Centos 5.2 uses by default still have php 5.1.* so you can just do a yum update or yum install php. The first step here is to set up the Remi repository. He maintains a repository that has the most up to date version oh php and all of its extensions. You can set this up by doing the following:

$ wget

$ wget

$ rpm -Uvh remi-release-5-7.el5.remi.noarch.rpm epel-release-5.3.noarch.rpm

This will set up the Remi repository for yum. By default it is disabled so you’ll have to use the –enablerepo option with yum when you are using it to install or update anything. So in order to update to php 5.2.* you just say:

$ yum –enablerepo=remi install php

To verify that you have php 5.2.8 installed issue a

$ php -v

And you’ll get a response like:

PHP 5.2.8 (cli) (built: Dec  9 2008 14:11:33)
Copyright (c) 1997-2008 The PHP Group
Zend Engine v2.2.0, Copyright (c) 1998-2008 Zend Technologies

At this point I assume you already have mysql and mysql-server installed and configured. If not just issue:

$ yum –enablerepo=remi install mysql-server

It will install all of the necessary dependencies including mysql. Configuring mysql server using mysqladmin is actually out of the scope of this but there are plenty of tutorials online for that. Make sure you set up your   and passwords for accessing it otherwise you’ll have issues later.

Now, you’ll want to install php-mysql. Again use the remi repository for this, otherwise you’ll end up with tons and tons of dependency issues. Trust me, I learned this the hard way…

$ yum –enablerepo=remi install php-mysql

This will install the module for you and add it to php.ini so you don’t need to add the It does the same for mysqli.

So now you’ve got everything you need set up properly, so install phpmyadmin. Get the tar ball from the server, extract it somewhere in your htdocs folder, create a system link called phpmyadmin.  Go into the phpmyadmin and create a folder called config. Issue:

$ chmod o+rw config

Now because you’ve already set everything else up, you won’t receive the errors that I got on my first attempts. Now go to http:/ and follow the steps there. It’s a very nice little graphical interface that helps you set the configuration file. After this is done, move the file in the config directory to the head of the phpmyadmin directory. Then remove the permissions you set before:

$ chmod o-rw config

That’s it. Now you can go to and log in using your credentials for mysql-server.

Hope this saves everyone from running into all of the issues I had.
