How to Install vim on CentOS 6.2

When I try to edit a file using vim instead of vi, the following error appeared. How to fix this?

[root@centos6 ~]# vim /etc/httpd/conf/httpd.conf
-bash: vim: command not found

Solution:

Simply run yum install command to install vim on CentOS 6.2. This steps has been tested on CentOS 6.2. Assume that you have installed minimal installation type CentOS 6.2 and has setup your own local yum repository. You can use internet CentOS yum repository instead if you have direct internet connection to your server.
