You have PHP 5.1.6 installed on CentOS 5.6 and want to update to PHP 5.3 like this:

The update aborts with the following error:

Enable the Epel and IUS repositories on your system.

For 64bit systems, you can find the correct packages here:

For 32bit systems, the correct packages are here:

After you have found out the correct links for the Epel and IUS rpm packages, you can install them like this:

rpm -Uvh
rpm -Uvh

Then import the GPG keys for both repositories:

rpm –import /etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL
rpm –import /etc/pki/rpm-gpg/IUS-COMMUNITY-GPG-KEY

Install the yum-plugin-replace package:.

yum install yum-plugin-replace

You can now replace your PHP 5.1.6 packages with the PHP 5.3 packages from IUS like this:

yum replace php –replace-with php53u

You can search for further php53u packages like this:

yum search php53u

If you find php53u packages that you’d also like to install, pick them from the search result list and install them as follows:

yum install php53u-pear php53u php53u-cli php53u-common php53u-devel php53u-gd php53u-mbstring php53u-mcrypt php53u-mysql php53u-pdo php53u-soap php53u-xml php53u-xmlrpc php53u-bcmath php53u-pecl-apc php53u-pecl-memcache php53u-snmp

Check your PHP version afterwards – it should display 5.3:

php -v

[root@server1 ~]# php -v

Finally restart your web server. For Apache, this can be done as follows:

/etc/init.d/httpd restart
