The following outlines the old way to upgrade/downgrade IUS packages. These processes still work, but have been replaced by the usage of the ‘yum-replace-plugin’:
Contents
Admittedly, upgrading from stock RHEL packages to IUS is not exactly an easy transition, but trust us it’s worth it in the long run. Because of the way IUS packages are created, you can not simply do a ‘yum upgrade <package>’ because the IUS packages actually conflict with the stock RHEL packages. What you really need to do is first remove the stock RHEL packages, and then install the corresponding IUS package you want. Lets use php on my stock RHEL5 box and first see what packages we need to remove:
[root@el5-i386 ~]# rpm -qa | grep php
php-gd-5.1.6-23.2.el5_3
php-cli-5.1.6-23.2.el5_3
php-odbc-5.1.6-23.2.el5_3
php-mbstring-5.1.6-23.2.el5_3
php-pear-1.4.9-4.el5.1
php-pdo-5.1.6-23.2.el5_3
php-5.1.6-23.2.el5_3
php-xml-5.1.6-23.2.el5_3
php-common-5.1.6-23.2.el5_3
php-ldap-5.1.6-23.2.el5_3
php-mysql-5.1.6-23.2.el5_3
php-imap-5.1.6-23.2.el5_3
Note: php-pear is not part of the php package set. It is it’s own package.
Looking at this list I can see that I want to remove everything but ‘php-pear’. You can do this by ‘rpm -e –nodeps...’ but a cleaner, safer, more appropriate way would be to use yum shell:
Short version with no output:
[root@el5-i386 ~]# yum shell
> remove php-gd php-cli php-odbc php-mbstring php-pdo php php-xml php-common php-ldap php-mysql php-imap
Setting up Remove Process
> install php52-gd php52-cli php52-odbc php52-mbstring php52-pdo php52 php52-xml php52-common php52-ldap php52-mysql php52-imap
> transaction solve
> transaction run
NOTE: It is *very important that you run ‘transaction solve’ to ensure all dependencies are being met with the new packages. Removing packages with unmet dependencies in Yum can lead to a nightmare of packages being removed.*

And now, you should have a working install of PHP 5.2 on RHEL5:
[root@el5-i386 ~]# php -v
PHP 5.2.10 (cli) (built: Jul 28 2009 14:54:01)
Copyright (c) 1997-2009 The PHP Group
Zend Engine v2.2.0, Copyright (c) 1998-2009 Zend Technologies
But don’t forget to check and restart Apache:
[root@el5-i386 ~]# httpd -t
Syntax OK
[root@el5-i386 ~]# /etc/init.d/httpd restart
Stopping httpd: [ OK ]
Starting httpd: [ OK ]
Downgrading is really the same process but backwards. You first want to determine which packages you want/need to remove:
[root@el5-i386 ~]# rpm -qa | grep php52
php52-common-5.2.10-1.2.ius.el5
php52-mbstring-5.2.10-1.2.ius.el5
php52-xml-5.2.10-1.2.ius.el5
php52-cli-5.2.10-1.2.ius.el5
php52-mysql-5.2.10-1.2.ius.el5
php52-ldap-5.2.10-1.2.ius.el5
php52-pdo-5.2.10-1.2.ius.el5
php52-odbc-5.2.10-1.2.ius.el5
php52-5.2.10-1.2.ius.el5
php52-gd-5.2.10-1.2.ius.el5
php52-imap-5.2.10-1.2.ius.el5
You then need to remove, and replace with stock packages:
[root@el5-i386 ~]# yum shell
> remove php52-gd php52-cli php52-odbc php52-mbstring php52-pdo php52 php52-xml php52-common php52-ldap php52-mysql php52-imap
> install php-gd php-cli php-odbc php-mbstring php-pdo php php-xml php-common php-ldap php-mysql php-imap
Setting up Remove Process
> transaction solve
> transaction run
And of course we once again have stock PHP for EL5:
[root@el5-i386 ~]# php -v
