Systemd Unit file for Minecraft Server
- Connect to the server or if you want to run the server on your machine, open a terminal
- Become root using
su
orsudo
- To validate that you're now root, run
id
- To validate that you're now root, run
- Next install the necessary packages
apt-get install -y openjdk-11-jre-headless curl screen nano bash grep
- Create the
/opt
folder if it doesn't already existmkdir /opt
- Now you need to create the user for the service
adduser --system --shell /bin/bash --home /opt/minecraft --group minecraft chmod +t /opt/minecraft
- Create the Systemd Unit file:
or
nano /etc/systemd/system/[email protected] # paste the contents of [email protected]
curl https://raw.githubusercontent.com/agowa338/MinecraftSystemdUnit/master/minecraft%40.service > /etc/systemd/system/[email protected]
Each server has it's own subdirectory of /opt/minecraft
. This means that when a new server is being added, the following steps need to be followed:
- Create a subdirectory of
/opt/minecraft
for your Minecraft server, we'll be usingfeed-the-beast
as an example- It is recommended to use a name which only includes lowercase characters, spaces should be replaced with dashes
cd /opt/minecraft mkdir feed-the-beast
- Upload your files to the
/opt/minecraft/feed-the-beast
directory- Note: All uploaded files should be owned by the
minecraft
user
chown -R minecraft:minecraft /opt/minecraft/feed-the-beast
- Note: All uploaded files should be owned by the
- Accept the Minecraft server's EULA
echo 'eula=true' > eula.txt
With [email protected]
it's possible to specify the RAM allocation per server. This can be done using a server.conf
file in the server's directory.
Example
# /opt/minecraft/ftb-beyond/server.conf
MCMINMEM=512M
MCMAXMEM=2048M
Some Feed the Beast packs include a FTBInstall.sh
. This script needs to be executed before starting the server.
cd /opt/minecraft/ftb-beyond
su -c 'bash /opt/minecraft/ftb-beyond/FTBInstall.sh' minecraft
systemctl enable minecraft@ftb-beyond
systemctl disable minecraft@ftb-beyond
systemctl start minecraft@ftb-beyond
systemctl stop minecraft@ftb-beyond
To enter the console, screen
is used.
All screen sessions are owned by the minecraft
user and are prefixed with mc-
.
# This will attach to the Minecraft server called `ftb-beyond`
su -c 'screen -r mc-ftb-beyond' minecraft
Note: To detach (exit) from the session, press CTRL + A followed by D.
