Is there an "idiots guide" to getting a vanilla MC server up and running - specifically for someone who doesn't play the game itself?

 

My son has been badgering me to get him the Java edition and so I have doe today but him and his mates want to play on a dedicated server.

 

I don't play the game myself and my only experience in using my unraid machine for a server is for 7 Days to Die - which has a very handy "config" file - this seems to have something similar but I can't see things such as what I want to call the server and a password field to join - are these doable?

 

Sorry if this is basic stuff, all I want is to host a dedicated server for 4 or 5 players!

Minecraft keeps crashing and I need to constantly restart the server for my kid. I'm wondering if there is a way to export his world data, save it, then delete/reinstall the binhex minecraft server to see if that fixes the issue. I've tried googling but haven't found exactly what I'm looking for. TIA.

OK, the issue is all around glibc and the upgrade to the package on arch linux, this caused failure when attempting to build arch linux docker images, but looks to also cause other side effects, such as the ones above. The fix is actually included in the latest runc (part of docker) but unraid has not upgraded yet to the latest version, thus you are seeing the issues caused by glibc upgrade.

 

To manually upgrade you simply replace the existing statically built runc with the latest, this can be achieve by going to the unraid terminal and executing the following:-
 

curl -o '/usr/bin/runc' -L 'https://github.com/binhex/arch-packages/raw/master/static/x86-64/runc' && chmod +x '/usr/bin/runc'

 

Then start the container without privileged flag set and it should start fine (works for me). The reason i wasn't seeing the issue before was that i had completely forgotten i had upgraded by version of runc, thus i was not seeing any of these issues, doh!.

 

note:- the above command will need to be executed each time you reboot the server as everything is in ram, but you can automate this by adding that line into your 'go' file located at

\\<server ip>\flash\config\go

 

 

@binhex I have been unable to get the :latest version to work even when starting from scratch. I am running on ubuntu 20.04 (not unraid) I tried your above code but it didn't help. When I attempt to connect I just get a connection refused error if I try logging into the webUI terminal it logs in but then says "There is no screen to be attached matching minecraft."

 

If I instead use 1.16.5-02 everything works fine. No idea what is going on logs don't seem to be helpful.

 

Also just a heads up your docker/github template example has "-e WEBUI_CONSOLE_TITLE=Minecraft Server \" and the space in "Minecraft Server" throws an error. I think you used to have it as "Minecraft_Server"

 

Really appreciate your help I have been running 5 or 6 minecraft containers over the last year and everything has been great.

can you please attach the log /config/supervisord.log

I just updated it now fails with:

Doh! Sorry for not reading first. Confirmed resolved by the updated runc version.

I don't understand this reply?  I had a docker update and it is now no longer starting with the same error(s)

Hey guys,

Where am I going wrong?

see the pinned post at the top. it runs you through the fix.

@binhex could you elaborate on how to get the change to be persistent? I'm not familiar at all with the go file.

@jamerperson

open the unraid terminal

cmd: cd /boot/config (my flash drive is mounted as /boot.  seems other installs could be /flash, so YMMV.)

cmd: nano go

go to the first blank line, and type/paste:

curl -o '/usr/bin/runc' -L 'https://github.com/binhex/arch-packages/raw/master/static/x86-64/runc' && chmod +x '/usr/bin/runc'

type <ctrl+o>

type <y> to save

type <ctrl+x> to exit

close the console.

flash is the default share name if it's exposed over SMB, so the go file would be \\tower\flash\config\go if you wanted to edit it over the network, and the flash share was enabled.

ah....

I don't expose myself, I mean my flash, via SMB.

Just a quick shout out for for some guidance.

 

I used the @SpaceInvaderOne video to setup a Minecraft server and also used Cloudflare. Worked a treat. Ran for a week or so. Then had an update for Binhex's container (great work on all your containers, use them for everything!) and it updated with no errors but then the minecraft server was not available on the local network or via the internet. When you connect to the WebUI for the container (user name and password work fine) you get the following message in the window:

 

"There is no screen to be attached matching minecraft." 

 

and that's it. Previously the WebUI showed all the data for the minecraft server, who connected, what the world was doing, etc.

 

There was another container update and I had the glibc error which I corrected with the post in this thread and that's all fixed so no problems there. However, I still get the console window error and the minecraft server not being able to connect. The container starts and runs, had a look through logs and couldn't see anything obvious.

Log posted below. Any help is greatly appreciated (username and password deleted from logs).

Is it possible to use a custom jar with this container?

 

I tried adding "CUSTOM_JAR_PATH: /config/minecraft/spigot-1.16.5.jar" as a variable but it still launches the minecraft default jar.

yes, that was added in and tested so it should work, please can you attach the file /config/supervisord.log

try a different browser, i have a funny feeling ive seen this before and it was browser related, if you are using firefox try chrome, if chrome try firefox.

no, it was introduced later on, but if you run latest then you can run whatever version of minecraft you want right :-).

Ahhh I didn't know it was such a new feature. I was trying to avoid the current workaround for the current glibc issue, but I guess thats no longer an option for me. Thanks.

Hi,
