Support Portal  »  Knowledgebase  »  Viewing Article


NOTE: If you use the REMI repository (sited below) the default PHP will be PHP 5.3.x - THIS WILL BREAK JOOMAL and MANY Web Apps

See bottom for using alternative Atomic Repository

REMI Repository Method

Installing PHP 5.3.x on RedHat ES5, CentOS 5, etc (original link below)
I’ve had to follow this tutorial a few times myself now so decided I should share it with the world.

A few of our applications which make use of SOAP get a Segmentation Fault if run with PHP 5.1.x or lower. We believe this is due to a bug in PHP but can’t be sure, regardless it works fine in PHP 5.2.4 and above.

Problem is, RedHat ES5 does not have support at this time for anything higher than 5.1.6, and we didn’t want to break RPM dependancys etc by installing from source.

To install PHP 5.2.5 (Highest in repository at this time) you can make use of a RPM repository maintained by Remi. He has a repository for each distro, but to save you translating for the ES5 one I’ll give you the commands here. Run the following to get up and running:

rpm -Uvh remi-release-5*.rpm epel-release-5*.rpm
You now have the Remi repository on your system, however it is disabled by default. Obviously you don’t want all of your packages been effected by this repository, however to enable it for a specific package, run the following:

yum --enablerepo=remi update php
You should now have the latest PHP5 installed:

# php -v

Update 12th Aug ‘08:
There is now an English page on the Remi site on how to configure repositories for all sorts of distros:

Atomic Repository Method

Install Atomic Repository On a CentOS Server:

At Your Linux command line type:

The above command will download the script and then execute it. First the script installs the Atomic GPG key. Unless you have a Plesk server that you want packages for you can answer “n” when asked if you want to enable the Plesk yum repository. After this it will install the atomic.repo file in /etc/yum.repos.d/ directory.

At the command prompt type:
# yum --enablerepo=atomic update php*

Once it is finishe run:
# php -v
and you should see:

PHP 5.2.12 (cli) (built: Jan 31 2010 12:53:32)
