Computer Tips - Linux: How can I restart a service/daemon when it dies?

Date: 2010jun1 OS: Linux Language: bash Warning: This doesn't work with systemd Q. Linux: How can I restart a service/daemon when it dies? A. Of course, its best to locate the reason why its dying. But as a Bandaid you can do this. If your service MYSERVICE is at issue make file /etc/cron.hourly/check_MYSERVICE that contains:
#!/bin/sh if /sbin/service MYSERVICE status | grep -q 'is running'; then : else echo "MYSERVICE seems to be down -- restarting" /sbin/service MYSERVICE restart fi
And make it executable:
chmod a+x /etc/cron.hourly/check_MYSERVICE
You'll get mail when it restarts the service (no mail when checks it and its OK). You can do this for multiple services.
