cron job for Linux servers to restart cf-execd when it dies

[Aleksey Tsalolikhin]

Hi,

This is the cron job I use to make sure I always have CFEngine running.  cf-execd process may die (like any daemon), and the following cron job, run once every five minutes, will bring it back up if the /etc/init.d/cfengine3 script is executable. 

[ -x /etc/init.d/cfengine3 ] && if ! pgrep cf-execd > /dev/null ; then /etc/init.d/cfengine3 restart >/dev/null ; fi # keep cfengine3 service running. If you want to turn off CFEngine, run: chmod -x /etc/init.d/cfengine3 && /etc/init.d/cfengine 3 stop

I haven't tested this on anything but RHEL.

Best,

I think the thing I miss most after years of Solaris administration and moving to Linux is SMF. It completely eliminated the need for things like this. And I haven't quite worked up the nerve to venture into systemd-land yet, myself, but going back to cron jobs to ensure services being up feels (to me) much like getting rid of the automobile and going back to a horse and carriage :-)

I don't mean to sound negative on your solution, though, don't get me wrong - I'm just feeling nostalgic :-) Hopefully, some will find it useful, thanks for sharing!

After talking to Brian and now you, I'm starting to get nostalgic. I got my professional start on Solaris.  I remember being amazed at dynamic reconfiguration -- ability to migrate processes of a RAM/CPU board in a mid-range server, power off that board only, replace it while the server is live, and then power it back on and migrate processes back onto it -- back in 2001.  Advanced technology!

Thanks, Jason.  :)

Hi Martin,

You can write policy code al you want, but if CFEngine isn't running it cant promise anything.
That sounds like A false promise to me ;-)

Cheers,
Patrick
