Despite my best efforts, my media streaming server still dies sometimes and I am in a random place trying to ssh into the server to restart it on my cell phone after customers start calling.... I tried using google to track down a script that would do the following
Every 5 min execute:
sudo /etc/init.d/WowzaMediaServer status
Then it would grep the returned text for "started" and if it isn't found would execute:
sudo /etc/init.d/WowzaMediaServer start
I am not sure how to setup the script + it is going to ask for a password to use the sudo command.
Anybody able to give me a hand? Seems like a nice script that many people should have on hand anyway.
You probably don't need sudo just to do /etc/init.d/service status. Which is fortunate since running sudo every five minutes could fill your logfiles with pointless junk.
sudo can be configured to let a certain user run a certain program without a password.
I'd just have cron run a script file. If checking every hour is fine, you could just put the script in /etc/cron.hourly/check-mediaserver.sh and it'd run it hourly under the cron user.
In the script file:
Code:
#!/bin/sh
source /etc/profile
/etc/init.d/WowzaMediaServer status || sudo /etc/init.d/WowzaMediaServer start
Depending on your init system this may generate output that'd get mailed by your cron daemon if it can, or end up in dead.letter if it can't.
You can edit your sudo permissions as root with visudo. You could add a line like:
Code:
cron ALL=NOPASSWD: /etc/init.d/WowzaMediaServer
...which would let the cron user run /etc/init.d/WozxaMediaServer as root without a password.

I wrote a quick little script that will eventually end up as a cron job to export rrd files for my cacti server.
Here is the script:
#!/bin/bash
rm -rf /backup/cacti_xml/*
cd /var/www/html/rra
ls -1 *.rrd | awk '{print "rrdtool dump "$1" > /backup/cacti_xml/"$1".xml"}' | sh -x
Is there... (5 Replies)

Hi!
I'm using a script to start a process that might run forever if some parameters are given wrong (it's part of an optimization). I would now like to have the process killed after a certain walltime in that case. So far I get it done with the following lines

Thanks for the all the help last evening on CRON jobs. It's now working.
Is it possible with cron to save a backup of a file to a different server or location? The idea being that if one host goes arse over tit, I'll have a backup of the DB on another server?
Many thanks,
