How to install MineOS-node in a jail (alternative to using the MineOS plugin)

[bal0an]

This recipe still works for TrueNAS 12.2-RELEASE jails. Migration from 11.3-RELEASE using iocage upgrade -r 12.2.-RELEASE mineos-jail failed, so I decided to setup a new jail and migrate the servers.

I used the UI for creating the new jail. It should be roughly equivalent to:

Code:

iocage create -n mineos-jail -r 12.2-RELEASE
iocage set mount_procfs=1 boot=on allow_raw_sockets=1 mineos-jail
iocage start mineos-jail

The linprocfs flag does not exist but is required. It needs to be added by

Code:

mount -t linprocfs linprocfs /mnt/tank/iocage/jails/mineos-jail/root/usr/compat/linux/proc

which I added as a POSTINIT scripts of the TrueNAS host. Otherwise the WebUI fails to work properly.
I created my users using parameters (instead of interactively):

Code:

pw user add -n john -G games,wheel -m -s /usr/local/bin/bash

In the webui for a minecraft server you need to use the the group john to hide your servers from other users. Use group games in your servers if you want them visible to others. My three sons have a use case if one wants to set up a "private" server for himself and his friends.

The linprocfs flag does not exist but is required. It needs to be added by

iocage set mount_linprocfs=1 mineos

 

[bal0an]

Setting linprocfs using iocage works on TrueNAS 12.0, it is not available through the UI, though.
Also, I wonder where mount_linprocfs actually mounts the filesystem, and whether it will be visible at /usr/compat/linux/proc?

 

[Jurgen Segaert]

Hmmm... you are correct; both flags mount_procfs and mount_linprocfs do not show in the UI of TrueNAS-12.0-U1
This is a regression from FreeNAS 11.3. Use the command line as per @Patrick M. Hausen 's post above until this gets sorted out.

iocage mounts procfs on /proc and linprocfs in /compat/linux/proc in your jail.

Code:

➜  ~ mount | grep procfs | grep mineos
procfs on /mnt/ssd/iocage/jails/mineos/root/proc (procfs, local)
linprocfs on /mnt/ssd/iocage/jails/mineos/root/compat/linux/proc (linprocfs, local)

Just out of interest i've got the server working but have a couple of people on bedrock clients who would like to play.

They could do this with GeyserMC, but i'm just wondering how you handle this. I'm not up to speed enough to know if I can just create a second MC instance and forward the traffic or if GeyserMC will even run on TrueNAS.

I create a new server in the web interface - called mineos-Geyser and then in the jail shell did:

Code:

mkdir -p /usr/local/games/GeyserMC
cd /usr/local/games/GeyserMC
fetch httpsci.opencollab.dev/job/GeyserMC/job/Geyser/job/master/lastSuccessfulBuild/artifact/bootstrap/standalone/target/Geyser.jar
screen
java -jar Geyser.jar

Stop/ edit config.yml

I think I may have an issue

1) because the jail is running NAT. Will i have to translate the bedrock ports as well?

2) Now getting a cert error on the mine-os web interface. Assuming this is something to do with Geyser settings or not running very latest version of the server?

3) Assuming ponting to remote host at 127.0.0.1 in config.yml won't work?

Any help/tips appreciated.

 

[Jurgen Segaert]

I haven't heard about GeyserMC, but it looks like it's a proxy that allows a BedRock Minecraft client to connect to a Java Server.

DragonProxy is a very similar solution; a while ago I managed to get that one to work with MineOS, see post #107 in this thread.

You can run multiple servers/instances simultaneously, as long as you increment the port when you create additional servers so that they all listen on a different port. By default, Java servers use port 25565. The unofficial MineOS plugin and instructions in post #1 forward ports 25565 through 25570; if you have more servers and you use NAT, you'll have to add and additional ports to the nat_forwards option.

The same goes for GeyserMC/DragonProxy; you'll also have to forward that port, probably the standard BedRock port 19132.

I just went through this ordeal. I tried to get all the commands in order for someone else attempting to run MineOS on there TrueNAS system.

Code:

iocage create -n mineos-jail -r 12.2-RELEASE
iocage set mount_procfs=1 boot=on allow_raw_sockets=1 mineos-jail
iocage set mount_linprocfs=1 mineos
iocage start mineos-jail
iocage console mineos

pkg
y

pkg update
pkg upgrade -y
pkg install -y py37-rdiff-backup rsync gmake screen git-lite python37 py37-supervisor node npm openjdk8-jre wget bash nano

mkdir -p /usr/compat/linux/proc
mkdir -p /usr/local/games
cd /usr/local/games
git clone git://github.com/hexparrot/mineos-node minecraft
cd minecraft
chmod +x *.sh

Will give it a shot over the weekend on a blank dev box. Thanks!

As an alternative to the ordeal, you can just install the community plugin.

 

[0nighthawk0]

Are you all installing screen for a reason over tmux? Does the install actually need it anywhere.

 

[Jurgen Segaert]

The upstream project needs screen.

I made a new 12.2 jail with MineOs as the latest and greatest code would not build in the older jail, but MineOs will not list my old Minecraft servers.

Everything under /var/games/minecraft/ is owned by mcserver:games

# id mcserver
uid=199(mcserver) gid=199(mcserver) groups=199(mcserver),13(games)

”Refresh Server List” does nothing. “Create New server” had an old Server join the list. “Create New server” again had the new server join the list. If I log off and back in the server list is empty.

Something is also wrong with the “Profiles" as it only list three sources, and sometimes when hitting “Refresh Profile List” it adds another source to the list that it in the log had issues with. If I log off and back in the list is again three sources.

“Import a Server” list everything as expected though.

I have tried to figure out how I did solve these familiar issues in the past but I can’t remember, or if I never knew how it was fixed.

I do not think the log is saying anything useful.

made a new 12.2 freebsd jail with MineOs in as the latest and greatest code ( fixed forge json profiles list from 404 · hexparrot/mineos-node@603d9c5 · GitHub) would not build in the older jail.

The mcserver user started getting issues with the Web-UI already in the old jail when adding new servers, Web-UI would not list my old Minecraft servers, or the new one, anymore, so I tried to get them back by updating the code, but got other issues aswell with the new code.

I was able to fix my issues on my old servers in the new jail by simply

Code:

chown -R jimstein:mcserver /var/games/minecraft/* 

This is counter intuitive and the reverse of what I want (mcserver:games) but this allows me personally edit files through a SMB share and mcserver can be used to login and manage the list of Minecraft servers. This setup do not allow me to have anyone else log in to MineOS or anyone else edit the files on the SMB share. This is not needed but I want it to be setup to allow that.

The problem with the Profiles was also solved by doing this.

But still:
* I can not start my old server even if they now are listed in the webgui.
* I can create a new server from import and run it but it will not start on reboot.
* The problems remains with the new servers that never was started that they are not listed in gui. I had one join the server list but it was lost again after restarting the webgui.

The stupidity of computers…

As an alternative to the ordeal, you can just install the community plugin.

My problem with the MineOs community plugin has always been this:
Error: mineos-plugin-jail had a failure Exception: RuntimeError Message: pkg error: - py37-rdiff-backup : Refusing to fetch artifact and run post_install.sh! Partial plugin destroyed

 

[Jurgen Segaert]

This just started a while ago, as the default version of Python switched from 3.7 to 3.8. See the post below.

MineOS plugin install error - py37-rdiff-backup failed to install

Hello Everyone, I am very new to both TrueNAS and MineOS. About a month ago, I installed them both and had no problem getting a MC server up and running. After attempting to get a Fabric install to work, things seem to be very messed up. Long story short, I have tried to start from scratch...

www.truenas.com

 

[Jimstein Perrless]

That is not the only thing that has updated. The cause of all pain was that Java was updated to openjdk11.

Check your java version.

Code:

java -version

openjdk version "11.0.10" 2021-01-19
OpenJDK Runtime Environment (build 11.0.10+9-1)
OpenJDK 64-Bit Server VM (build 11.0.10+9-1, mixed mode)

To fix that one needs to downgrade:

Code:

pkg delete -y openjdk11-jre
pkg install -y openjdk8-jre

If your jail is v12 you should also do some mounting from the host.

Code:

mount -t fdescfs null /mnt/red/iocage/jails/mineos-12-jail/dev/fd
mount -t procfs null /mnt/red/iocage/jails/mineos-12-jail/proc

The mounting needs to be done permanent by adding it to fstab or as a postinit script

 

[Jurgen Segaert]

Most of the profiles now require Java 11. The issue isn't Forge itself, I just tested that, but some of the mods you use or install may be fussier than others. There is another thread in this forum also pointing this out; if I remember correctly that related to a mod that was using sqlite/sqlitejdbc and that pkg is build for Java 8.

 

[Jimstein Perrless]

That is good to know. I can keep mineos-jails around for the different needs depending on the age of the profiles used. I mainly is dealing with Forge profiles for 1.12.2 and 1.14.4 btw.

 

[Patrick M. Hausen]

If your jail is v12 you should also do some mounting from the host.

Code:

mount -t fdescfs null /mnt/red/iocage/jails/mineos-12-jail/dev/fd
mount -t procfs null /mnt/red/iocage/jails/mineos-12-jail/proc

The mounting needs to be done permanent by adding it to fstab or as a postinit script

These are easily available in the jail settings in the UI. No need to script it on the host.

 

[Jimstein Perrless]

Actually, the fdescfs flag does not exist in gui. It can be set by
iocage set mount_fdescfs=1 mineos-jail
You can just aswell do when your at it
iocage set mount_procfs=1 mineos-jail
I did also need to create the folders /dev/fd and /proc in the jail before I could mount, ofc.
