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

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.

    Worked like a charm and thanks I have been at it for a while and this saved me a ton of time. Awesome!

  2. John Van Haastert says:

    Having a difficult time with mcrypt extension. Did you have this problem?

  3. Tim says:

    I installed it using the remi repository as well. Have you attempted that yet?

  5. Tim says:

    Have you checked your php.ini configuration to see that mcrypt is being loaded. Then restart httpd.

  6. John Van Haastert says:

    There is no entry in /etc/php.ini for mcrypt. Do you have the syntax in your php.ini file?

  7. Tim says:

    Just add the line:

    To your /etc/php.ini file and it should work fine. You may need to restart httpd.

    Thanks that worked. I installed “mcrypt” instead of “php-mcrypt”;(.

  10. Dan says:

    Yea this doesn’t work for me.

    I have the exact same problem, but I’m getting this output (php remains as 5.1.6 from 2006):

    Transaction Check Error:
    file /etc/my.cnf from install of mysql-libs-5.1.32-1.el5.remi conflicts with file from package mysql-5.0.45-7.el5

    • timt881 says:

      Remove all of your current php related packages including php itself, then use the steps listed above. You’re getting conflicts because of previously installed packages.

  11. Dan says:

    Yea that did it. Thanks alot.

  12. ken says:

    except that removing the php packages will not clean it up. I have the same error. removed php and now I’m stuck in an odd state.

  13. Dan says:

    Wow I’ve found myself referring to this page a lot while setting up my new lamp server. Thanks so much for writing this.

  14. Tim says:

    Can you do the equivalent of –replacefiles in rpm with yum? Or do I have to uninstall the old el5 rpms?

  15. Dan says:

    This repository installs MySQL 5.1.32. I’m having a great deal of trouble transferring my stored routines from a production server running 5.0.67. I wonder if anyone has been able to successfully use stored procedures with this installation?

  16. steward says:

    Connecting to||:80… connected.
    HTTP request sent, awaiting response… 404 Not Found
    14:19:10 ERROR 404: Not Found.

    … so much for Step One.
    Is this a temporary problem I wonder?

  17. The Squad says:

    Great Tutorial. I have another method to install phpmyadmin from the newest version at sourceforge on my site.

    I was SO excited when I finally started making progress and then I ran into the mcrypt issue. I have tried everything suggested here, as well as the yum-utils suggested below…

    You could try using –skip-broken to work around the problem
    You could try running: package-cleanup –problems
    package-cleanup –dupes
    rpm -Va –nofiles –nodigest
    [root@localhost phpmyadmin]#

    I imagine I am having trouble due to something that has changed in the repos since these previous posts.

    Any suggestions?

      Since the original writing of this article, those repos have been updated… Please refer to this same article at for a more updated copy. If that doesn’t help, feel free to touch base again and I’ll get back to you and see if I can help.
