Bash Script to check if services are running and restart if not. Sends email to you. Tested with Ubuntu 14.04 and 16.04
##INSTALL:
- put into your scripts folder
- set your email address
- set the services you want to keep an eye on (by default it has mysql and apache2..you can add or take away whatever you need)
- save your changes
- create a cronjob as root (sudo crontab -e) and add something like this, which runs every minute (adjust to your needs):
#check on services
*/1 * * * * /your/path/to/scripts/services
The script will check the status of each service. If the service is stopped, it tries to restart the service. If the service starts, it sends you an email saying the service stopped but was restarted.
If the service does not start for some reason, it sends you an email telling you it was not started.
After that, it will continue to try and start, but not send any more emails until the service is finally started.
