Raspberry Pi 2 or 3 - Minecraft Server

The new Raspberry Pi 2 has got twice the RAM and a load more processing power, so will it make a better Minecraft server?  The old Pi made an adequate Minecraft server providing you only had a few players and you kept the view distance low.

Update - The Pi 3 takes it up a step and provides more stability and connectivity is a lot easier.


I tried both the vanilla server and a spigot server, both similar results, both performed reasonably well, but Spigot seemed a little more stable (but this is only based on feeling).  I was only able to test with up to 3 players but it worked well under those conditions.


Setting up your own server is pretty simple.

You will need to download either the vanilla server from Mojang or build your own spigot server jar file.

Note - The instructions below, will take you through how to create a vanilla server, if you have built spigot the only difference will be the name of the 'jar file' you put into the start.sh file

1. Make a directory for your Minecraft server

mkdir ~/MinecraftServer
cd ~/MinecraftServer

2. Download the 1.8.1 vanilla Minecraft server jar file

wget https://s3.amazonaws.com/Minecraft.Download/versions/1.8.1/minecraft_server.1.8.1.jar

3. Create a script to run the server jar file

nano start.sh

Enter the following command which will run the server

java -Xmx1024M -Xms512M -jar minecraft_server.1.8.1.jar nogui

Ctrl X to exit & save

4. Make the script executable:

chmod +x start.sh

5. Run the server

./start.sh

You should receive a message asking you to accept the EULA.



6. Accept the EULA (end user license agreement), open eula.txt

nano eula.txt

Change:

eula=false

To:

eula=true

Ctrl X to save and exit

7. Run the server

./start.sh

The first time the server runs it will take a while to start as it creates a new world.

Once you see the word "Done", the server is up and running and you should be able to connect to the server using Minecraft choosing Multiplayer, Direct Connect and entering the IP address of the Pi.


You can shutdown the server by typing the command "stop" in the command window .

If you find the server is slow, particularly when generating chunks (i.e. creating new bits of the world when you get to the edge), you could try reducing the view distance.  I reduced it from 10 to 7 and this seemed to make the server more responsive.

8. Edit view-distance in server.properties

nano server.properties

Change:

view-distance=10

To:

view-distance=7

Ctrl X to save and exit

Restart the server for the change to take effect.

      Got it running ... couple things. I was running Apache, PHP, MySQL and PostSwitch on it ... it would load up, and run for a few minutes, but as I started walking around the server kept falling behind and would eventually crash.

      At first it was doing it regularly, so I Overclocked it - roughly the same effect. Then I changed the memory swap ... all the way down to 16 for GNU - this died quick ...then all the way up to 256.

      at 256 it lasted about 5 minutes longer. I think a fresh install will be my next test, and ONLY running Minecraft.

      I'll update with results

      I tried using the vanilla server on my B+ but it was super slow to start up and crashed when I went on it. I then disabled a lot of extras like animals, mobs, and villages in the server.properties file. I also overclocked my Pi to "turbo." Even then, it crashed after about a minute. I wasn't running anything else at the time. The only other thing I have installed is the tightvncserver. What could I try to make the server work?

      I have previous run a Minecraft server on a Raspberry Pi 1 (not the 2 which this post is about) http://www.stuffaboutcode.com/2013/09/raspberry-pi-setup-minecraft-server.html using Spigot.

      I had to change the memory config and turn the view distance down considerably to make it stable.

      in the terminal:

      I would also recommend trying the spigot build, it does tend to be perform better than the vanilla build but in my limited tested I didnt really notice a big difference.

      Thanks, i used a view distance of 5 and allowed flight but if i flew to far and to fast it crashed. I did try the spigot build but ran into difficulties. I followed your link and eventually it seemed to of built but going to the spigot folder shows no .jar files

    You can also use MCServer. It's a C++ Minecraft server. We managed to get around 7 players with the previous Pi (although we did disable some things like entities, water/lava physics and redstone).

      MCServer... I thought I was running that, but mine is the 1.8.3 .jar...
      That sounds like java, not C++...
      Where can I download a C++ MCServer from? That should (could) be a lot faster than the Java-server!

      There are six people (me included) playing on MCServer every day now, and we had only very few problems. There are some bugs, but everyone is enjoying, and willing to wait. I just wish the thing had version numbering. I never know when a new version is out. With actual changes, not a snapshot.

      Bugs: Doors fall out of frames if they're not placed in a specific way. Chests, doors and beds multiply or re-appear in your inventory. We have monsters disabled after we encountered invisible creepers. Pictures disappear, and item frames cause errors and nearby blocks get deleted.

      But once you know these things you're good! I just wish I knew when something is fixed so I could redownload.

      No problem! This time it should really create a world.ini for you, that you can modify as well. By default the world has a specific default seed, is endless, has monsters, and is uncompressed - and really large. My world.ini download link in the older comment should still work.

      It'll have no monsters at night (they are horribly bugged), a max world radius of about 70 chunks, and compression enabled.

      On a sidenote, it makes sense to download the plugin "NoChunkFall" from the link below, for installations on the Pi, so people do not fall through the empty world or suffocating in rocks when spawning, and it loads too slow.

      https://github.com/DevToaster/NoChunkFall/archive/master.zip

      There is a Plugins directory with subdirectories for each. Unzip this one into a folder called NoChunkFall, and then edit settings.ini -- find the plugins section and add what you need:

      [Plugins]
      ; Plugin=Debuggers
      ; Plugin=HookNotify
      ; Plugin=ChunkWorx
      ; Plugin=APIDump
      ; Plugin=NoFireSpread
      Plugin=Core
      Plugin=TransAPI
      Plugin=ChatLog
      Plugin=NoChunkFall

      Delete
    10. Unknown5 March 2015 at 10:05

      @Jammet
      When installing the NoChunkFall stuff, as you suggested, it looks like I get a NoChunkFall-master (not a NoChunkFall) so the settings.ini should be edited adding: Plugin=NoChunkFall-master
      Is that correct?

      When I start the server using that I see:
      [10:57:30] -- Loading Plugins --

      Seems to be running well and fast! I have one question though…
      We live in The Netherlands and my son, the real MineCraft Player here, prefers a flat world to build on. I have tried to set: level-type=FLAT in the [general] part of the world.ini and also in the settings.ini, but that doesn't seem to work.
      Can you give me a hint? Is there any docs somewhere about the structure and possibilities of both .ini-files?

      I have created a script that installs MCServer from scratch and I am having quite some fun building and rebuilding it just about everyday… It takes about an hour on my Pi2, which is connected to the internet over a 4Mbps ADSL link.

      Delete
    13. Jammet6 March 2015 at 12:56

      To be honest, I have no idea. Maybe - just maybe, you could pre-generate a flat world in standard Minecraft, spend some time wandering and generating a lot of chunks, before then copying the world data to MCServer, and see if that works out reasonably well? The world files are compatible, even if the generators don't produce the same results.

      Maybe using a search-engine you could find seeds that generate a world that's more level than other ones, but the world generator here is not at all likethe one in original Minecraft and it could look awkward.

      Amazing work on the build script. I could imagine the people at the MCserver Forum (the actively developing people there) might be interested in such a thing as well. At the very least they'll be able to provide definite answers world generator questions. :)

      Delete
    14. Jammet6 March 2015 at 16:30

      I've asked for what you are looking for on the MCServer Forum. Here is how you do it:

      You do that by going to your world's world.ini and changing the values in [Generator] to:
      BiomeGen=Constant
      ConstantBiome=Plains
      HeightGen=Flat
      FlatHeight=5
      CompositionGen=Classic
      ClassicSeaLevel=0
      ClassicBeachHeight=-1
      Finishers=

    I used to run a Spigot server with a reduced map distance and pre-generated light map with reduced max-height test with 5 players, ran well... but i wonder, there used to be automatic builds of Spigot jars.. They don't exist anymore? I guess i'm gonna try to build the server later. Just in case, would you be nice enough to provide the build of Spigot you ran? :)

      Just in case it could help someone else, i could finally build Spigot.
      From the buildtool page, they say to do
      "sudo apt-get install git openjdk-7-jdk tar"
      So i had installed openjdk-7-jdk and i don't know which version was installed before that. By removing that package (and autoremove the rest) and because i couldn't run a vanilla server anymore, i could then successfuly build Spigot.

    Since all the original Java based servers keep crashing no matter what, I gave MCServer a go (mentioned above) and this one really blows them all out of the water with how performant it is. Set the view distance to 7, like here, and edited the world.ini file so that compression was set to 6 (best setting, really).

    And that's that. Seriously, if anyone else, like me, fiddled around with spigot, vanilla and Java for hours and hours, only to see them crashing time and time again, get MCServer instead.

      Once you started MCServer once, and it has created a new world, stop it with the stop command.

      It will have created that new world in a directory called "world".
      Inside that directory is the world.ini file.
      It contains the compression setting as well as the seed for that world.
      Remove everything here except the world.ini file, change the compression setting to 6, and - if you want - change the seed, save the file, and restart MCServer to get the new world in compressed format, and the seed of your choice.

    5. Jammet26 February 2015 at 13:59

      Oh yes, and one more thing: Right now, the monsters in the game are very buggy. You should change the difficulty setting to 0 (peaceful) and then you can enjoy the basic survival mode. Chests, doors, and beds have placement and dublication bugs in many positions, but once I figured that out, it was alright. And I am sure these bugs are going to be fixed in the coming releases.

      This isn't a server for Minecraft: Pi Edition is a server for the full PC version of Minecraft.

      If you want to play multiplayer on the Pi Edition just start a game on one Pi and the 'Join' the game from the other Pi(s).

      An alternative would be to start a Minecraft Pocket Edition game or server from version 0.3.3 if MCPE. That is Pi version compatible, or largely so.

    ReplyDelete
  21. Unknown21 April 2015 at 19:20

    If you're running om a Pi2 then use these values:
    STARTMEM = 512M
    MAXMEM = 896M

    Also: There is a 1.8.4 available! Try that!

    Also: I installed both the Java and the C++ version. My son, the MC-player, prefers the java-variant because he know how to control it (commands and stuff).
    And believe me, on a Pi2 it works. Although you do need to make some adjustments to the server.properties file.
    My son uses (don't ask me why):
    gamemode=1
    difficulty=0
    max-tick-time=-1
    view-distance=7

      It looks like you are trying to run the minecraft server 'gui'. This wont run on an ARM computer as it requires an x86 java library liblwjgl.

      You have to run the jar file directly using the command java -Xmx1024M -Xms512M -jar minecraft_server.1.8.1.jar nogui

      Your pi is fine. Sometimes you need a very specific Java runtime environment. I rid myself of these troubles by using the MCServer instead of the original Minecraft server. Though it's changing it's name to Cuberite. www.cuberite.org

      If nothing else helps, give it a go.

      Thanks. Looks like I've got MCServer running okay. I've a port clash / forwarding issue going on at the moment but it should be easy to resolve that. I'd still like to know where I went wrong on the vanilla and Spigot installs but I'll leave my investigations to another day! Thanks again.

    NoSpawnChunks doesn't work I repeat NoSpawnChunks DOES NOT WORK. It's all a placebo. This plugins only loads up and pretends to unload chunks but the memory still fills up with time until it uses up all the swap and crashes the server.

    You can try it yourself by removing the plugin and comparing the perfromance, it will be identical.

    Install htop:

    sudo apt-get install htop

    That way you can monitor closely the memory and cpu usage.
