Start services on a restart automatically..

Skillz · 04-02-2009, 12:23 PM

How would I run scripts automatically if a server gets rebooted/restarted from the user who owns those scripts?

Say I have a teamspeak server running under the users tsclient and the startup script to start the server is

./teamspeak2-server_startscript start

How would I execute that script, with that user, automatically on a server reboot?

I'm not sure if this is the best solution, but you could add to /etc/rc.d/rc.local (in Slackware, I don't know about other distributions) something like this:

Code:

su owner_user
./teamspeak2-server_startscript start

Seems like it would work, are there any drawbacks to doing it that way, specifically security issues with it?

On an RPM-based distro use the rc.local file. I've been told Deb-based distros don't use rc.local though so YMMV. I'm a Mandriva/Fedora/SuSE guy.

If you using Redhat/CentOS/Fedora/Mandriva/Suse/Slackware, then you can add the script to /etc/rc.local like this

su - username -c 'cd /path/to/the/script; ./teamspeak2-server_startscript start'

and if not then u will have to build a small start/stop script which you can add to /etc/init.d if in case you are using Debian/Ubuntu and then just run:

update-rc.d -n script_name defaults

Its quite simple, Good luck!

Example:

Code:

#!/bin/sh

USER=teamspeakuser
SCRIPTPATH=/path/to/the/script

case $1 in
     start)
     echo -en "Start Teamspeak: "
     su - $USER -c 'cd $SCRIPTPATH; ./teamspeak2-server_startscript start' >/dev/null 2>&1
     echo -e "\t done"
     ;;
     stop)
     echo -en "Stop Teamspeak: "
     su - $USER -c 'cd $SCRIPTPATH; ./teamspeak2-server_startscript stop' >/dev/null 2>&1
     echo -e "\t done"
     ;;
     *)
     echo "Usage: $0 {start|stop}"
     exit 1
esac

exit 0

Thx, but I hope he's gonna use it or its gonna work for him.

If the user has a shell, you could simply add

@reboot commands_go_here

to the user's crontab

Thanks for the suggestions guys!! I did what Robert said, seemed to be the easiest way.

I would like to point out that anyone who wants to use it for starting teamspeak on a server reboot, you need to use restart. Since teamspeak creates a file with the PID and a graceful shut down of teamspeak deletes this file, a server reboot doesn't. So teamspeak thinks it's still running when the server is rebooted. Using restart forces it to attempt to stop the server, but then it starts it again.
