Currently I have mysql 5.5 installed localy.
How can I install and use mysql 5.1 server?
I also need to be able to go back to 5.5. at one point.

It will not downgrade with 5.5 config files.
apt-get purge mysql* -y
find / |grep -i mysql
And backup and remove all folders, then install mysql 5.1.
As for upgrading to 5.5, use apt-get upgrade
.
Don't forget to DUMP all your databases (mysqldump or phpmyadmin)!
