To monitor running services and restart them if they stop working you can use Monit.

Here is the guide to install it:
https://www.digitalocean.com/community/t...gure-monit

But for a basic install run:

Code:
apt-get install monit

My setup:

Code:
nano /etc/monit/monitrc

And edit:

Code:
set httpd port 2812
    use address 12.34.56.789 or monit.YourDomain.com # only accept connection from localhost
    allow 0.0.0.0/0.0.0.0        # allow localhost to connect to the server and
    allow admin:*password*      # require user 'admin' with password 'monit'

And add this to the bottom of the file.

Code:
#Apache Monitor
check process apache with pidfile /var/run/apache2/apache2.pid
    start program = "/etc/init.d/apache2 start" with timeout 60 seconds
    stop program  = "/etc/init.d/apache2 stop"
    if failed host YourDomain.com port 80 protocol http then restart

#MySQL Monitor
check process mysqld with pidfile /var/run/mysqld/mysqld.pid
    start program = "/etc/init.d/mysql start"
    stop program = "/etc/init.d/mysql stop"
    if failed unixsocket /run/mysqld/mysqld.sock then restart

Code:
service monit restart

Here is an example of Monit restarting Apache when it went down 7hrs ago.

I can not over state how well this has worked for me.
