Its merely a reminder so i dont go through the search to restart mysql on one of my stupid servers:
Usually (i think) its like this:
/etc/init.d/mysqld start /etc/init.d/mysqld stop /etc/init.d/mysqld restart
On that server of mine, because of some config:
/etc/rc.d/init.d/mysqld start /etc/rc.d/init.d/mysqld stop /etc/rc.d/init.d/mysqld restart
