# Distributed under The MIT License (MIT) # A shell script for updating the minecraft server jar file on Linux Servers The main script itself does all the heavy lifting, and has many configurable parameters based upon your setup. JAR_PATH='/home/minecraft/server/server.jar' # Change this to point to your server.jarĬhown minecraft:minecraft $JAR_PATH #Change your user & group if needed While these scripts worked when originally posted, anyone can edit the wiki, and furthermore your system or setup may be different than was used to create them.

The following is a simple example wrapper script for a setup using a separate user and group for the server, and a server that is started and stopped through systemd. Should you need to stop the server, change permissions on the newly downloaded file, and start the server again afterwards, a wrapper script is recommended. This script only handles updating the server JAR file itself.

To Install the required dependencies on a Debian platform perform the following commands To Install the required dependencies on CentOS 7 perform the following commands On other distributions it may be available, or may require installation from source. On CentOS 7 jq is available through the EPEL repository. The JSON parser jq is used to extract the relevant information out of the manifests. This script relies on cURL to handle downloading of Mojang manifests and the server JAR file itself. This script was written on CentOS 7 but should work for any POSIX compliant Linux distribution so long as the dependencies are available. Target installation version will default to the latest release, though any version can be specified. Default parameters can be modified within the script, or passed in as parameters.

This is a detailed bash script to update a vanilla Minecraft server. Yes, usually /etc/systemd/system/ if added by the sysadmin.This tutorial is exclusive to Java Edition. The socket-file (in this case minecraft.socket?) has to be placed in the same directory as the service? Sockets=xxx contains the name of the Socket you created above, correct? It will still send SIGKILL after a certain time unless you add some more parameters (man systemd.kill). This prevent sending SIGTERM to the server process and cause a premature stopping of the process. Why do we have to use KillSignal=SIGCONT? Here are some clarifications from suggestions of the original author. service file, it is automatically added by the Sockets= option, the BindsTo= option will take care of stopping the socket and cleaning up the FIFO file when the service stops.

You don't have to take care of adding dependencies to the. ĮxecStart=/bin/sh -c 'exec /usr/local/bin/services/minecraft/run.sh /run/ntrol'īonus, you'll be able to send command to the server using echo '/command' > /run/ntrol anytime. Then ExecStop will simply write to the new socket to send '/stop ' to the input.

Then modify your rvice file to not send SIGTERM, bind standard input to the socket by modifying ExecStart with an exec wrapper. Additionally, the unit's ExecStop command echo '/stop' > /run/ntrolĭoes not work either and the server gets killed by the sigkill signal instead.Īdd a new minecraft.socket file (assuming your service is named rvice) to bind your server's input to: If there's no output in the fifo, the journal of the rvice unit displays Unknown command. Sometimes gives me an output when viewing the ntrol fifo (with cat) and sometimes not.

When sending a command using echo '/help' > /run/ntrol Unfortunately, the commands passed through the ntrol fifo do not work.

Unfortunately I could not figure out how to modify the ExecStop command to send internal commands to the minecraft process.ĮxecStart=/bin/sh -c 'java -Xms2G -Xmx4G -XX:+UseConcMarkSweepGC -jar spigot-1.14.4.jar /run/ntrol' I've read that simply using the kill command will not terminate the server gracefully and one should use the minecraft-internal 'stop' command instead. WorkingDirectory=/usr/local/bin/services/minecraft/ĮxecStart=/usr/local/bin/services/minecraft/run.sh Everything seems to work but I assume the way I'm terminating the server on stop command is not the best one. I'm building up my linux knowledge (at least I'm trying) by setting up services for different game servers.Ĭurrently I'm working on a Minecraft Server that shall be started automatically on a server restart.
