Arma3 Linux Server Tools

A package of tools i made for managing an Arma3 server on Linux.

If you have any questions, feel free to contact me or open an issue, although the support on this will be minimal.

My server structure:

Everything is stored inside the home directory for the steam user.

• Steam/ (directory for steam downloads (arma mods, etc))
• arma3/ (directory containing arma3 dedicated server)
• steamcmd/ (folder where steamcmd is installed)
• (all of the tools included here)

Setup

Create a steam user

useradd -m -s /bin/bash steam
sudo -i -u steam

Download SteamCMD

mkdir ~/steamcmd && cd ~/steamcmd

sudo apt-get install lib32gcc-s1 # SteamCMD deps
curl -sqL "https://steamcdn-a.akamaihd.net/client/installer/steamcmd_linux.tar.gz" | tar zxvf -

Download Arma3 dedicated server.

bash ~/steamcmd/steamcmd.sh
force_install_dir ./arma3/
login (user) (password)
app_update 233780 validate
exit

Install mods

Install/update mods:

bash ~/steamcmd/steamcmd.sh
login (user) (password) # Account must own Arma3

# Do this for each mod:
workshop_download_item 107410 (modId) validate
# If the download timeouts, or errors, just repeat the command. It'll continue where it left off.

After installing/updating mods:

python ~/syncmods.py

Some info about syncmods.py:

• Creates a symlink between arma3 downloads, and the game dir
• Renames mod path's so that they work with linux
• Creates a mods.txt file and automatically passes it to run.sh (so that all the installed mods are loaded on startup)

Run server:

I suggest you run the server in a seperate terminal (for ex. using screen) so that it doesnt stop working when you disconnect your terminal from the server (check out the code below). But if you still want to run the server in the current window, then just do this:

bash ~/run.sh

Run server with screen

screen -r # open a new screen
bash ~/run.sh # in the new screen

# If your connected to the server, you can close the window now, the server should continue working.

Kill server (if its not running in your current terminal)

ps -ef | grep steam # get the arma server pid from here
sudo kill (arma3server_x64 pid)
