Minetestserver Deamon

[JPRuehmann]

Hello

It would be fine if minetestserver could work in the Background without any User loged in (deamon).
As now, the user that has created the server has to be logged in all the time.
The init scripts you find in the net wont work, because minetestserver wont find anything.

Thanks,
JPR

Just run minetestserver --world <path to your world> --config <path to minetest.conf> --logfile <path to debug.txt> from the initscripts.
Here's how you would do it for Arch Linux:
1) Create user minetest
2) mkdir -p /home/minetest/world
3) touch /home/minetest/minetest.conf
4) chown -R minetest /home/minetest
5) Write to /etc/systemd/system/minetestserver.service:

Your phone or window isn't wide enough to display the code box. If it's a phone, try rotating it to landscape mode.

Code: Select all

[Unit]
Description=Minetest server
After=network.target

[Service]
Type=simple
User=minetest
ExecStart=/usr/bin/minetestserver --world /home/minetest/world --config /home/minetest/minetest.conf --logfile /home/minetest/debug.txt

[Install]
WantedBy=multi-user.target


6) systemctl enable minetestserver && systemctl start minetestserver

Hi
Thanks for your infos
since none of the init scripts on the internet nor your description works complete for me
I will post my way. It is based on all the information i got.

1) sudo adduser -s minetest
2) sudo -u minetest mkdir /home/minetest/.minetest

copy the script to /etc/init.d

Your phone or window isn't wide enough to display the code box. If it's a phone, try rotating it to landscape mode.

:


edit the PROGRAMPATH and DATAPATH as needed
sudo chown root:root /etc/init.d/minetestserver
sudo chmod 775 /etc/init.d/minetestserver
sudo ln /etc/init.d/minetestserver /etc/rc2.d/S21minetestserver
repeat that for rc3, 4, 5.d
sudo ln /etc/init.d/minetestserver /etc/rc0.d/K21minetestserver
repeat that for rc1 and 6.d

that worked for me on Kubunte 12.04 LTS
Thanks,

@JPRuehmann thank you, I used your example to configure minetestserver for automatic startup at boot in Debian 8 (Jessie/testing). Could you please indicate what licence this piece of code is licensed under? I'd like to submit it for inclusion in the minetest-server package in Debian.

I believe you forgot one last step:

Your phone or window isn't wide enough to display the code box. If it's a phone, try rotating it to landscape mode.

Code: Select all

sudo update-rc.d minetestserver enable

I had to change the heading of the file, I used the example in /etc/init.d/skeleton. I also changed several paths, the minetest-server package in Debian puts it in /usr/games/.

The resulting final file is as follows:

Your phone or window isn't wide enough to display the code box. If it's a phone, try rotating it to landscape mode.

Code: Select all

#!/bin/sh
# kFreeBSD do not accept scripts as interpreters, using #!/bin/sh and sourcing.
if [ true != "$INIT_D_SCRIPT_SOURCED" ] ; then

Hello
It is based itself on Code that I've found on the Net.
Since theyŕe all free.

I think I can put it under the WTFPL.

Have Fun with it.
JPR

P.S. I prefer to create the links in /etc/rc.* myself.

[MagicFab]

Actually minetest-server is under "LGPLv2.1 and later"
http://metadata.ftp-master.debian.org/c ... _copyright

If you see no objection I'll submit it using that licence instead. There was some discussion about licensing minetest contributions in Debian here:
viewtopic.php?id=7163

I see I could probably do WTF I'd like with it, but as a matter of principle I prefer asking than doing.
