My cpanel WHM kept failing on upgradeing cause i still had mysql 5.0 installed. I upgraded and now I have sites down. Can I go back? If not how do I fix my sites that are down?!?!?!?!??!
Do you see any errors in mysql logs or during starting of mysql service? A close look at it will help to correct the issue. A mysql upgrade should not cause any problems.
After upgrading Mysql, please make sure that you have compiled Apache+PHP+Mysql using Easyapache.
You can perform it through WHM after Mysql upgradation or manually on shell by running /script/easyapache.
