I needed to setup a Minecraft server so that one of my kids could play online against a friend who had moved to another continent and they wanted a few different ways to stay in touch. Since one half of the friendship doesn’t have Xbox Live, but both have the PC / Mac version I figured I could sort out a hosted server for them to play on. There are plenty of places around that will host one for you for a small fee, but since I had some monthly Windows Azure credits via my MSDN subscription I figured I’d have a go setting up my own one and see how that went.
Initially I looked at deploying a pre-packaged Minecraft server from the Azure Marketplace, but the first two attempts failed to deploy so I looked at other possible options.
It seemed a popular choice when people were setting up their own was a Spigot version, partly because it looks like there are loads of different plugins which can be added at a later date. So I went down that route.
Deploying an Ubuntu VM
From the Azure portal I selected to deploy a new VM from the Gallery:
Then picked the latest version of Ubuntu available in there:
Fill out the Virtual Machine configuration dialogue. Note: to use SSH key authentication you need to supply an X.509 certificate.
Enter some more configuration details on the next page, including which datacenter region to host the VM in. Also be sure to add an additional port as an endpoint to include that which the Minecraft game needs, 25565.
On the last page, check you are happy with the selections and then tick to go!
Sit back in comfort and wait for the VM to deploy:
Once complete, you’ll have a nice VM ready for you:
I hadn’t used Azure before and found it to be quite a nice experience overall.
Connect with SSH to the VM and check whether Java is installed:
sudo apt-get install openjdk-7-jre-headless
then confirm it is installed:
Install Minecraft Spigot
*Full details can be found here*
Make a directory for downloading the Spigot build tools to and download the file:
sudo mkdir -p /opt/Minecraft/build cd /opt/Minecraft/build/ sudo wget https://hub.spigotmc.org/jenkins/job/BuildTools/lastSuccessfulBuild/artifact/target/BuildTools.jar
Run BuildTools.jar from the terminal – this took about 10+ mins for me:
sudo git config --global --unset core.autocrlf sudo java -jar BuildTools.jar
Eventually you should get something like this for a successful completion:
Create a new directory to host the compiled jar file and copy it there:
sudo mkdir /opt/Minecraft/play sudo cp /opt/Minecraft/build/spigot-1.8.7.jar /opt/Minecraft/play/spigot.jar
Create a new startup script (start.sh) in the directory to launch the the JAR:
sudo vi /opt/Minecraft/play/start.sh
paste the following code into the start.sh file:
#!/bin/sh java -Xms512M -Xmx1024M -XX:MaxPermSize=128M -jar spigot.jar
Add run capabilities to the start.sh script. Run the start.sh script to start the initial run of the server, you’ll be prompted that the EULA needs agreeing to:
sudo chmod +x start.sh sudo ./start.sh
Edit eula.txt and set eula=true
sudo vi eula.txt
Run the startup script again and this time the server will start fully:
Typing help at this point will give a list of commands that can be used interactively. You can also set the configuration of the game by issuing a stop then editing the server.properties file.
Now would be a good time to test you have set things up correctly. Fire up the Minecraft game and head into Multiplayer. Add a server and enter the details:
Once complete, the server should appear as available to connect to:
Oh no, it’s night time already!
Run Spigot as a service
Now all we need to do is run the Spigot server as a service, rather than interactively, otherwise the game dies when we drop the SSH session.
(Note: I expect there is a better way to do this than what I came up with, but I’m by no means a Linux expert, so feel free to leave a comment if you have a better way)
Create a minecraft.service file
sudo vi /etc/systemd/system/minecraft.service
Paste the following into that file:
[Unit] Description=Minecraft Server [Service] WorkingDirectory=/opt/Minecraft/play ExecStart=/opt/Minecraft/play/start.sh [Install] WantedBy=multi-user.target
Start the service and check the status:
sudo systemctl start minecraft.service sudo systemctl status minecraft.service
All being well you should see the service begin to start up:
