I have installed MySQL manually using rpm and familiar with process.
However, I would like to know how does yum update process works for MySQL.
- How do I check which MySQL version yum is going to pickup ? How to I know whether it is going to pickup Percona or Community ? How do I check this ?
- When we do yum update, what process does it follows for mysql upgrade e.g. lets say If I have MySQL 5.5.42-37.1 Percona Server , would it be upgraded to MySQL 5.5.42-37.3 version or 5.6 some version ?
- Normal upgrade process requires that we unistall previous version and then install new version and do mysql_upgrade process, does yum follows same process.
- What about backup before upgrade ?
Thanks a lot.
