[mysql] 安裝後出現 [ERROR] Fatal error: Can't open and lock privilege tables

Uninstall mysql using yum remove mysql*

Recursively delete /usr/bin/mysql and /var/lib/mysql

Delete the file /etc/my.cnf.rmp

Use ps -e to check the processes to make sure mysql isn't still running.

Reboot server with reboot

Run yum install mysql-server. This also seems to install the mysql client as a dependency.

Give mysql ownership and group priveleges with:

chown -R mysql /var/lib/mysql

chgrp -R mysql /var/lib/mysql

Use service mysqld start to start MySQL Daemon.
