Installing Yum on CentOS 5.3

Here are the simple steps to install yum on plain centos 5.3 x86_64 bit server.  login into the server with root user and execute the following commands.

rpm –import http://mirror.centos.org/centos-5/5.3/os/x86_64/RPM-GPG-KEY-CentOS-5

rpm -ihv http://mirror.centos.org/centos/5.3/os/x86_64/CentOS/libxml2-2.6.26-2.1.2.7.i386.rpm
rpm -ihv http://mirror.centos.org/centos/5.3/os/x86_64/CentOS/libxml2-python-2.6.26-2.1.2.7.x86_64.rpm
rpm -ihv http://mirror.centos.org/centos-5/5.3/os/x86_64/CentOS/python-elementtree-1.2.6-5.x86_64.rpm
rpm -ihv http://mirror.centos.org/centos-5/5.3/os/x86_64/CentOS/python-iniparse-0.2.3-4.el5.noarch.rpm
rpm -ihv http://mirror.centos.org/centos-5/5.3/os/x86_64/CentOS/python-sqlite-1.1.7-1.2.1.x86_64.rpm
rpm -ihv http://mirror.centos.org/centos-5/5.2/os/x86_64/CentOS/m2crypto-0.16-6.el5.2.x86_64.rpm
rpm -ihv http://mirror.centos.org/centos-5/5.2/os/x86_64/CentOS/python-urlgrabber-3.1.0-2.noarch.rpm
rpm -ihv http://mirror.centos.org/centos-5/5.2/os/x86_64/CentOS/sqlite-3.3.6-2.x86_64.rpm
rpm -ihv http://mirror.centos.org/centos-5/5.2/os/x86_64/CentOS/yum-metadata-parser-1.1.2-2.el5.x86_64.rpm
rpm -ihv http://mirror.centos.org/centos-5/5.2/os/x86_64/CentOS/yum-3.2.8-9.el5.centos.1.noarch.rpm

Then finally you can execute yum update command to update the rpms.
