How do you install MySQL 5.1.34 on CentOS 5.5? I am trying to install Mysql 5.1 on cent OS. I researched  a lot but could not find any link which gives step by step procedure. Everywhere, there are vague answers. Can someone please give me steps to be followed to install Mysql 5.1 ?
While I would normally not recommend this

CAVEAT
When running the download for MySQL 5.1.34, if the RPMs for the MySQL Binaries do not get retrieved, change this line
MYSQL_MIRROR_INDEX=0

to
MYSQL_MIRROR_INDEX=1

One value or the other will work.
