CentOS 6.8. How to add autostart to a service?

Question

FreeSWITCH

I got a virtual machine, from an old system administrator, with CentOS 6.8 it has a freeswitch on it. Service keeps dropping. you have to restart it manually with the command: service freeswitch restart. Actually a noob question: how can I set an automatic restart after a service crash? I'm not good with Linux, but I've never used CentOS at all.

Answer 1

You can use monit to monitor the service and restart it.
But it is better to understand why it falls.

Answer 2

The easiest way is to add service freeswitch start to cron and run it once a minute.
You can roll the zabbix agent onto this machine, and on the server already monitor the state of the daemon, and if it falls, start it on a trigger. But that's probably overkill.
In general, if you had a newer CentOS, there would already be systemd, where this issue is solved much more gracefully :)
But it is important to remember that all this is crutches, and you need to look for the cause of the daemon's fall for good.
