Keepalive of Nginx

gistfile1.sh

#!/bin/bash
# shell script which checks if nginx is still running 
# if not then it restarts the processes, including php-fpm
# this script should be called by a Cronjob every minute


# change the process name to whatever you want to keep alive:
PROCESS="nginx"  

if ps ax | grep -v grep | grep $PROCESS > /dev/null
then
        echo "$PROCESS is running"
else
        echo "$PROCESS is NOT running"
        # change the next line to the command you want to run for restarting:
        sudo /etc/init.d/php5-fpm restart && sudo /etc/init.d/nginx restart
