start cron service with supervisor

Question

I have the following in my supervisord.conf:

[program:cron]
command=service cron start
autostart=true
autorestart=false
stderr_logfile=/var/log/cron.err.log
stdout_logfile=/var/log/cron.out.log

Seems like it's failing?:

root@srv:/# supervisorctl
cron                             FATAL     Exited too quickly (process log may have details)

However it's running:

root@srv:/# ps aux | grep cron
root        52  0.0  0.1  26068  2464 ?        Ss   13:07   0:00 /usr/sbin/cron
root      3053  0.0  0.0  11284   936 ?        S+   13:08   0:00 grep --color=auto cron

Am I starting cron correctly with supervisor?

Answer 1

Possible to run cron in foreground?

command=service cron start

Should be instead:

command=cron -f

Answer 2

With supervisor the program you want to run, needs to stay on the foreground. You start cron as a service, so the program exits, and supervisor sees it as it stopped.
