(→Minecraft Server: Both of the "two" AUR packages referred to the same package, so removed one and added a section for the "manual" install (as well as a "request" to delete that). Cleaned up the remaining systemd instructions.)
(→Minecraft Server: SalGnt in #archlinux-arm couldn't get minecraft-server to work with OpenJDK; as soon as he switched to Oracle's, it worked. A similar notion is mentioned at http://minecraft.gamepedia.com/Tutorials/Setting_up_a_server#Arch_Linux_ARM)

AUR. This package includes the official game launcher plus a script to launch it.AUR is available in the
Otherwise, just get the launcher on the official download site.
If you installed Minecraft from the AUR, you can use the included script:
Otherwise, you will need to manually launch Minecraft:
$ java -jar Minecraft.jar
There are several programs and editors which can make your Minecraft experience a little easier to navigate. The most common of these programs are map generators. Using one of these programs will allow you to load up a Minecraft world file and render it as a 2D image, providing you with a top-down map of the world.
AMIDST (Advanced Minecraft Interface and Data/Structure Tracking) is a program that aids in the process of finding structures, biomes, and players in Minecraft worlds. It can draw the biomes of a world out and show where points of interest are likely to be by either giving it a seed, telling it to make a random seed, or having it read the seed from an existing world (in which case it can also show where players in that world are). AUR.AUR is available in the
Mapcrafter is a high performance Minecraft map renderer which renders worlds to maps with an 3D-isometric perspective. You can view these maps in any webbrowser and you can host them with a webserver for example for the players of your server. Mapcrafter has a simple configuration file format to specify worlds to render, different rendermodes such as day/night/cave and can also render worlds from different rotations. AUR.AUR is available in the
Minutor is described as a minimalistic map generator for Minecraft. Do not let this mislead you, it generates maps of existing worlds, not the other way around. You are provided with a simple GTK based interface for viewing your world. Several rendering modes are available, as well as custom coloring modes and the ability to slice through z-levels. AUR.AUR is available in the
Installing the server
To start the server via systemd:
$ systemctl start minecraftd
To start the server automatically during boot:
$ systemctl enable minecraftd
See systemd for more examples on how to use systemd to manage the server.
The screen session. You can monitor the Minecraft server by running this command:AUR systemd script starts the server in a
# sudo screen -r
(Remember that you can exit screen sessions with
/srv/minecraft/eula.txtwill be created. You will need to edit this file to state that you have agreed to the EULA to run the server.
/srv/minecraft. Add your user to the
minecraftgroup and add group write permission to the directory
/srv/minecraftto modify Minecraft settings.
/srv/minecraftdirectory are either owned by user Minecraft, or have r/w permissions for all three groups (user,group,other), otherwise server will error out.
You can also run a dedicated Minecraft server:
- Follow the steps above to install Java
- Download the multiplayer server from the Minecraft site
- Run the server:
$ java -Xmx2048M -Xms2048M -jar minecraft_server.jar nogui
(You can sub the -Xmx and -Xms values for the amount of memory you want your server to use. A good rule of thumb is one GB per ten users.)
- To configure the server, take a look at this wiki page.
- Establishing a Minecraft-specific user is recommended for security. By running Minecraft under an unprivileged user account, anyone who successfully exploits your Minecraft server will only get access to that user account, and not yours.
- To leave the server running unattended, look into tmux or screen.
- You may wish to modify your server, to provide additional features:
- You might even set up a cron job with a mapper to generate periodic maps of your world.
- ...or you could use rsync to perform routine backups.
