For some reason you need to downgrade MySQL 5 to MySQL 4.1 to achieve this you will have to do the following:

To check the which all mysql rpm’s are available use the command:

rpm -qa | grep -i mysql-

First of all take a backup of /var/lib/mysql, and also ask the other users to keep a backup it with them. This can also be a .sql file. The command to take a backup is:

cp /var/lib/mysql /var/lib/mysql.bk

Now, you will have to edit the cPanel config file and make manual changes under this, so edit it with the command:

nano /var/cpanel/cpanel.config

And here, find for the line “mysql-version=5.0” and change it to “mysql-version=4.1”

Now, we will forcefully install mysql by the following command:

/scripts/mysqlup --force

You can now check again with the command:

rpm -qa | grep -i mysql-

This is done and worked for me.
