-To set the proper ownership for the MySQL directories and data files, so that only MySQL (and root) can do anything with them.

***Default options are read from the following files in the given order:
/etc/my.cnf /etc/mysql/my.cnf /usr/local/mysql/etc/my.cnf ~/.my.cnf
[root@vps mysql-5.5.0-m2]# cp support-files/my-medium.cnf /etc/my.cnf
[root@vps mysql-5.5.0-m2]# chown root:sys /etc/my.cnf
[root@vps mysql-5.5.0-m2]# chmod 644 /etc/my.cnf
[root@vps ~]# cd /usr/local/mysql/bin
[root@vps ~]# for file in *; do ln -s /usr/local/mysql/bin/$file /usr/bin/$file; done
-To set up symlinks for all the MySQL binaries, so they can be run from anyplace without having to include/specify long paths.
Create Startup service for mysql
[root@vps ~]# echo "/usr/local/mysql/lib/mysql" >> /etc/
***Do not issue the above command more than once.

[root@vps ~]# ldconfig
[root@vps ~]# cp ./support-files/mysql.server /etc/rc.d/init.d/mysql
[root@vps ~]# chmod +x /etc/rc.d/init.d/mysql
[root@vps ~]# chkconfig mysql on

Here my server hostname is and therefore the error log name og mysql is . You can use find the error log in the var directory of mysql installation. Here in my case it is /usr/local/mysql/var/
You can set new mysql root password using the followiing command.
[root@vps ~]# mysqladmin -u root password <newpassword>
