Error installing newer version of MySQL on red hat enterprise 5.6
I install the distribution fine and then issue the command:
service mysql statusCode:
Service mysql restart
MySQL is not running, but lock exists [FAILED]Code:
MySQL manager or server PID file could not be found! Starting MySQL ........... Manager of pid-file quit without updating file.
Since this post I tried installing again but this time I couldn't complete this:
ERROR 2002 (HY000): can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)

It looks like the mysql server has not started up. I'm not used to installing MySQL from scratch, but maybe you can rectify this error by blowing away (or backing up and then blowing away) /var/lib/mysql/* and then start over.
As to the lockfile error, the mysql that ships w/RH typically keeps a lockfile at:
Your newer version of mysql may have installed an initscript (/etc/init.d/mysqld) that does not use this lock file, or uses a different one, but the original one still existed.
In any case, make sure your mysql server is stopped (you may have to kill processes outright), remove any lock files manually, install the new version, then check out the initscript (if one is included) and make sure you understand how the lock file is used.
