Unable to start MySQl

We are not able to start MySQL because of the error below.

I tried to remove the /etc/my.cnf. Always remember to back up the file first :). When i tried to start again the MySQL service still getting the errors. I tried to find some solutions in the web but i cannot find any related problems. I tried to set again the mysql configuration file. And when i tried to start MySQL and kaboom it started. hehehe.. I don't know why but i am able to start the MySQL :)

When i was starting the server i am seeing some weird logs before the MySQl started.

[root@TESTING01 etc]# service mysql start
/usr/bin/my_print_defaults: unknown option '--use-mysqld_safe'
