Title: Cron, Apache and a script
Post by: Thomas on July 23, 2003, 05:14:14 PM

Hi,

I'm using SME 5.6u4. Yesterday my Apache crashed for no apparent reason. I was able to restart it right away, as I was sitting right next to the machine when it happened.

But what If I had been away?

That got me thinking (I'm trying not to hurt myself): Could it be possible to make a script that checked if Apache is up and running, and the let Cron run that script every 5-10 minutes? If the script finds out Apache is either dead or crashed, then it does a apachectl restart.

What say all you SME wise people? Doable, or downright stupid?

Regards
Thomas

Easily done, however, instead of creating a band-aid, why not investigate as to why Apache is crashing to begin with.

Hello Nathan,

I'm sure Apache crashed due to some "system hiccup", since this server is only running pure and VERY simple HTML. I haven't been able to find anything odd in the logs either.

So this band-aid will be for those very rare situations where Apache just decides to shut down for no apparent reason.

Sincerely,
Thomas

Sounds like a winner to me:

Script you'll want to use is:
http://www.stickit.nu/utils/apachemon.pl

It's a perl script that runs in an infinite loop, you won't want to cron this, but rather add it to /etc/rc.d/rc.local
