If you’re getting 502 Bad Gateways from your WordPress site when using Nginx then the following cron job might help:
Add a .sh script with this content and set it to trigger every ten minutes:
#!/bin/bash
PHPCOUNT=`ps aux | grep ‘.php.sock’ | grep ‘php5.cgi’ | wc -l`
echo $PHPCOUNT
while [ “$PHPCOUNT” -eq 0 ]
do
/etc/init.d/nginx startphp
PHPCOUNT=`ps aux | grep ‘.php.sock’ | grep ‘php5.cgi’ | wc -l`
done
That should check the number of processes, and if it’s not correct restart them.
The script is /root/nginx_php.sh
The cronjob is installed under root, and this is the content:
ps19952:/var/spool/cron/crontabs# crontab -l
