Trying to install OpenX, we encountered a segmentation fault that caused the Apache httpd daemon to crash. The problem was caused by the libphp library. So we decided to upgrade from PHP version 5.1 to 5.2.
We start by creating a new file /etc/yum.repos.d/CentOS-Testing.repo:
# CentOS-Testing: # !!!! CAUTION !!!! # This repository is a proving grounds for packages on their way to CentOSPlus and CentOS Extras. # They may or may not replace core CentOS packages, and are not guaranteed to function properly. # These packages build and install, but are waiting for feedback from testers as to # functionality and stability. Packages in this repository will come and go during the # development period, so it should not be left enabled or used on production systems without due # consideration. [c5-testing] name=CentOS-5 Testing baseurl=http://dev.centos.org/centos/$releasever/testing/$basearch/ enabled=1 gpgcheck=1 gpgkey=http://dev.centos.org/centos/RPM-GPG-KEY-CentOS-testing includepkgs=php*
The last line makes sure that only PHP and related packages will be selected from the Testing repository. As long as you have deployed only the standard PHP packages, this should do the job. You can check out which packages are installed using this command:
rpm -qa |grep php
Updating
Now we are ready to perform the actual upgrade:

[root@services ~]#
New Configuration Files
As you can see, two .rpmnew files were created in the process. So we check whether the new /etc/php.ini.rpmnew file is different from the original /etc/php.ini:
diff php.ini.rpmnew php.ini.org
There are a lot of differences between the two, so we do another diff on our own current configuration and the original file:
diff php.ini php.ini.org
and we work the differences into the .rpmnew file:
cp php.ini.rpmnew php.ini.new mv php.ini.org php.ini.org.old vim php.ini.new
After which we put the new configuration file in place:
mv php.ini php.ini.old mv php.ini.new php.ini mv php.ini.rpmnew php.ini.org
We do the same for /etc/httpd/conf.d/php.conf:
[root@services conf.d]# diff php.conf.org php.conf.rpmnew [root@services conf.d]#
Since there were no changes to this file made between the two versions, we can simply remove the .rpmnew file:
rm php.conf.rpmnew
Restarting the Web Server
Now we are ready to restart the web server:
[root@services conf.d]# /etc/init.d/httpd restart Stopping httpd: [ OK ] Starting httpd: [ OK ]
And version 5.2 of PHP should be in place:
[root@services conf.d]# rpm -qa |grep php php-mysql-5.2.10-1.el5.centos php-cli-5.2.10-1.el5.centos php-pear-1.8.1-2.el5.centos php-gd-5.2.10-1.el5.centos php-pdo-5.2.10-1.el5.centos php-bcmath-5.2.10-1.el5.centos php-pgsql-5.2.10-1.el5.centos php-devel-5.2.10-1.el5.centos php-5.2.10-1.el5.centos php-soap-5.2.10-1.el5.centos php-common-5.2.10-1.el5.centos php-ldap-5.2.10-1.el5.centos php-mbstring-5.2.10-1.el5.centos php-xml-5.2.10-1.el5.centos php-ncurses-5.2.10-1.el5.centos php-odbc-5.2.10-1.el5.centos
