Help, I am trying to setup a cron job that checks mysql status every few minutes and it down restarts it.
Currently running the Ubuntu 12.10 WP Stack and have applied the swapfile tutorial too.
So if yall can help, please do.
Script mysql-check.sh
#!/bin/bash /usr/bin/mysqladmin ping| grep ‘mysqld is alive’ > /dev/null 2>&1 if [ $? != 0 ] then sudo service mysql restart fi
Added to cron

-
-
- sh -x /homesys-checks/mysql-check.sh
-
-

However it does not work and have know idea why.

Are you sure that the script’s path is correct? <code>/homesys-checks/mysql-check.sh</code> Shouldn’t <code>/homesys-checks</code> be <code>/home/sys-checks</code>?
How about this in your /etc/crontab
# Restart MySQL if it's down
* * * * * root service mysql status || service mysql start
