Hallo,
how do you start your OpenSim/Robust-installation under linux so it runs
under the correct user and the screen-console stays accessible?
When I try to start after doing a "su opensim -c screen ....." and try
to switch to the console I get "screen cannot open your terminal
'/dev/pts/1' - please check". I have also tried putting the su into the
command of the screen but it still does not work. The same occurs when
my monit tries to restart it with user opensim configured.
I'm not using monit, so I cannot say about that, but this works for me
(in Ubuntu 12.04 LTS):
root@opensim:~# cat /etc/init/opensim.conf
start on (local-filesystems and net-device-up and runlevel [2345])
stop on runlevel [!2345]
pre-start exec /usr/bin/screen -p 0 -d -m -S opensim su - opensim -c "cd
/data/opensim/opensim/bin/ && /data/opensim/opensim/bin/OpenSim.exe"
post-stop script
PID=$(cat /data/opensim/opensim.pid)
screen -r opensim -p 0 -X stuff "shutdown$(printf \\r)"
while kill -0 $PID 2>/dev/null; do
sleep 1
done
exit 0
end script
You need a PID file of course or the stop will not work at all. Also
upstart does not monitor if it dies...
The screen options:
-d -m forks screen into the background and forces it to open a new session
-S opensim gives the screen session a name (screen -r opensim will
connect to it)
The screen command in the post-stop script sends the command "shutdown"
to opensim and therefore shuts down opensim normally.
The kill & sleep is just there to pause the shutdown of the system until
opensim has completely shutdown, which can take a couple of seconds. You
could extend it with a timeout, but I didn't go there.
Regards,
Daniel
