linux - How to automatically restart the service when crush on CentOS?

Question

I have a docker service on centos, and I found that the docker service will crush in sometimes.

I have to run the command service docker start manually.

So how to watch the service and automatically restart when the services crush?

Thank you!

Answer 1

yes! use monit. Seems work

check process docker with pidfile /var/run/docker.pid
    start program = "/bin/systemctl start docker"
    stop program = "/bin/systemctl stop docker"
