mccli

This is a small program and library that makes it much easier to manage minecraft servers on GNU/Linux (and probably other) OSes. It provides some easy to use commands that allows you to for example, upgrade the server binary, create a new server or change the server port etc. just with one command. It also makes it easy to attach to the server console from the command line.

Install

Before installing, make sure the dependencies are installed.

# Ubuntu/Debian:
sudo apt install python3-libtmux python3-dbus python3-requests dbus-user-session tmux python3-pip
# You would probably want a java runtime too: 
sudo apt install openjdk-11-jre-headless

# Arch:
sudo pacman -S python-libtmux python-dbus python-requests
# JRE: jre-openjdk-headless

Then just follow these steps for a standard installation:

sudo useradd minecraft
sudo mkdir /home/minecraft && sudo chown minecraft:minecraft /home/minecraft
sudo mkdir /opt/mccli && sudo chown minecraft:minecraft /opt/mccli
sudo -u minecraft git clone https://github.com/alvesvaren/mccli.git /opt/mccli
cd /opt/mccli
sudo ./install.sh

Update

cd /opt/mccli
sudo ./update.sh

Note: If upgrading from 0.0.14 or earlier, run sudo systemctl disable /etc/systemd/system/minecraft-server@.service and sudo rm /usr/bin/mccli before upgrading

Another note: If upgrading from between 0.1.6 and 0.1.9, you might need to run sudo -u minecraft git reset --hard origin/master and then re-run the script ./update.sh

Help! My server doesn't start!

You are probably using the wrong java version or you are missing some dependency. Try running the server using mccli runner <name> and see why it errors out.

Develop

This is sort of broken right now but it should work after you've installed mccli at least once using the "Install" instructions

1. Clone the repository wherever you'd like
2. cd mccli

3. git checkout dev
   python -m venv env
   source env/bin/activate
   pip install -r requirements.txt

4. Make sure the mccli binary is correct (whereis mccli should return something that's in this repository)

Project status

Planned features:

• Code to interface with server files
  • Vanilla support
  • Paper support
  • Waterfall support
• Code to manage virtual console sessions (for example tmux)
• Systemd service (template) to start minecraft servers
• Code to manage systemd service
• Backup system (both automatic and manual)
• LXC (or possibly systemd-nspawn) support for running the servers in separate file systems (safer and easier to backup)
• Colors when running some commands

Other features that I might add in the future

• Web interface
• Spigot/Buildtools support
• Bungeecord support
• SSH server that just handles mccli
  • Client that can communicate using said ssh server
• REST api for use with some sort of client
• Command scheduling (you could probably do this with crontab already)
• FTP server
• Access policies to manage user access to different servers
• Automatic port forwarding using UPnP
• YML file support when using modify command
• Plugin manager
• CLI autocompletion
