Need auto restart script
- Thread starter ficolas
- Start date
ok, on my linux setup i spawn the minecraft jar inside a tmux session (that is a terminal emulator), (just make sure you have the -nogui flag when executing the jar.) that way i can easily setup cron-jobs to execute commands inside the tmux session, like automatic backups and stuff like that, the same way you can use cron-jobs to execute a server restart, and also give a warning 30sec before the restart, so that people can get ready for the restart. if you would like i can pastebin some scripts for you, but they will be tmux based. i can provide you a: "server start script", "server stop script" and "restart server" cron-job script, that you drop in your "/etc/cron.hourly/" folder in your linux server. does this sound like a good solution for your setup? are you looking for something simpler?
hmm.. i cant help with something simpler. sorry, i dont know java, so cant make a mod for that.
If you want a dirty way, you could always make a custom startup script. eg:
its a very dirty hack, but very simple, just modify the original "Server Start.sh" to contain the "code block section", i do not recommend that solution. as it does not make sure that the server properly save the world. it might corrupt your world.

echo "Stopping Server"
ps axa |grep " -jar FTB-Beta-A.jar" | awk '{print $1}' | xargs kill &>/dev/null
sleep 5

Put this in your minecraft-server dir
startserver.sh: http://pastebin.com/heR8RW5L
stopserver.sh: http://pastebin.com/6h26Vsne
put this in /etc/cron.hourly/:
http://pastebin.com/MDR0J5Fw
it has to be executable.
until someone release a better solution, this is the solution I would use.
Modify the scripts to match your needs/system. good luck.

Easiest way is to use screen and just make a shell script telling FTB console in screen to start and restart. Then just add it to your crontab once every hour.
That way you don't need to kill the process in an forced way.
Copy this script and name it what-you-want.sh
What is your linux distro? Depends on how to get screen but as Debiansystem you type:
To open a screen session with the name FTB type:
Start your server at the first time and detach the screen session with ctrl+a+d.
Add what-you-wish.sh (the shell script you just created) to your hourly crontab.
And you can just change the value of sleep to increase the time to wait for server restart. Don't forget to change the message also.
Edit: changed start command beginning with ./

screen -S FTB -X stuff "say Server restart in 5 minutes $(printf '\r')"

sleep 300
# Stops the server
screen -S FTB -X stuff "stop $(printf '\r')"
# Wait 10 seconds just to give the server time to shut down and save
sleep 10
# Starts the server
screen -S FTB -X stuff "./Server Start.sh $(printf '\r')"What is your linux distro? Depends on how to get screen but as Debiansystem you type:

to do hourly restarts in windows, just write a batch file to shut down your server, wait, then restart it. Then, tell taskmanager to run that batch file at your chosen time.
Or, install a real OS like Linux and stop trying to run an MC server in faildows...
Thanks for this. I'm struggling at the moment. I notice when watching the 'screen' that it enters the lines necessary but won't actually 'enter' / execute them. It just types the line, sleeps, then types the next line.
Any advice?
