Shell scripting and me

[william_hunter]

I am having a terrible time getting my server to restart after a crash or after calling reset. I have tried a variety of shell scripts and nothing seems to work. Can someone give me a complete shell script that fires up NWNx and then makes sure the server instance restarts when it goes down? This is very frustrating to me. I keep thinking I have it right and then...nothing..

Yes, I know I should just learn shell scripting, but my time is being consumed right now by life. I just don't have time right now.

Hi,

You can try this script as a start. It is a small script called nwnkicker.sh my husband wrote for me around the nwnstartup.sh script. The script will need to be executable of course and any paths changed to meet your needs.
This is simple and could use modifications. As it is you should run it in screen and then detach the screen session. When I want to end the server I reattach to the screen session issue an exit and hit control-c after the "nwn server exited..." is printed but before the server restarts.



#!/bin/sh
echo "Starting the nwn server for the first time..."
while ( true )
do
echo "Restarting the nwn server..."
/opt/nwn/nwnstartup.sh
echo "nwn server exited..."
sleep 5
done

Ah, so you actually call the nwnstartup.sh...sadly I never thought to do that. This makes sense to me now. Thanks.

Alright, so I am running the server on the above named script, but it seems the reset plugin is not fully killing the server process when reset is called. It shuts down but remains in the running processes list of the machine...any insights on that anyone?

I'm not sure. When I use the reset plugin with the script above the reset plugin kills the server and the script reloads the server. Is yours behaving differently or did you expect different behavior?

The script is restarting the server, that may be why you see a running process.

If the shell script is rebooting nwserver, something is not working right, because the mod isnt loading..it works fine the first time, but when I call reset, it shuts down and does not return, even though the nwserver process is running.

ok. I don't have the first line in my script.
Would you mind removing the #!/bin/sh from your nwnkicker.sh
Did you change the path for nwnstartup.sh in the script if needed?

Where is your nwserver installed, as well as the nwnstartup.sh script, and the nwnkicker script? Are they all in the same directory?

I take it the reset plugin works correctly when you do not use the nwnkicker.sh script? i.e. the server exits but does not restart.

The server not exiting fully is a known bug in relation to NWNX, that I dont have the details on.

You can work around it by tail'ing the nwserver log file and kill -9 the server when it says "Server exiting".

I really need to learn more about linux....I have no idea what that means (*grins sheepishly*)
