I need help on how to start the mysql server. The problem arise when the root directory was full. To be able to login to directadmin and start mysql, I added a soft link of the /var/lib/mysql/ to /home/mysql. Since my database used up the database. / directory has 50Gb and /home has 1.5Gb. But still I cannot start mysql.
/etc/init.d/mysqld status, below is the result:
MySQL is not running, but lock file (/var/lock/subsys/mysql)
I tried removing the file /var/lock/subsys/mysql
But when I tried to start mysql, it give me this result below:
[root@fst /]# /etc/init.d/mysqld start Starting MySQL.The server quit without updating PID file (/var/lib/mysql/fst.srv.net.pid).
I already check the permissions and file owner of mysql but with the same result.
chmod 755 -R /var/lib/mysql chown mysql:root /var/lib/mysql
I also cannot locate mysql.sock. But I guess it will be created by mysql when it starts.
Below is the content of the error logs

It puzzles me what the problem is. Kindly extend your help to me. I have been researching this problem for two days now.
