I recently migrated from MySQL 5.0 to Percona Server 5.1. I used
yum remove mysql-server mysql-client
to remove the old version. Then I installed Percona Server using
Since then, everyday at the same time, my
mysqld would shut down and restart on its own. The strange thing is that when it comes back up, it would no longer be Percona Server 5.1 but the previous version: MySQL 5.0!
And then I'd remove MySQL 5.0 and install Percona Server 5.1 once again. But the same thing would happen the next day at the same time: shut down, revert to old version, and restart.
I guess something is shutting down MySQL everyday at the same time. And then it reinstall the old version of MySQL and startup the old version.
How do I find out what is going on? And how do I fix this? This is driving me crazy.
Thank you for your help.
OK so it seems like cpanel is the problem here. Can anyone tell me what is cpanel doing here and how can it "bring back" the old version of MySQL? And how could I fix it?
