ArmA 3 Linux Dedicated Server Steam Install tutorial instructions.

Go to your home directory. Make “steam/” directory there.

mkdir steam

Make “arma3/” directory there.

mkdir arma3

Go to steam directory and download the steam client.

wget http://media.steampowered.com/installer/steamcmd_linux.tar.gz

Unpack it.

tar xvf steamcmd_linux.tar.gz

And run it the first time when it should upgrade itself automatically.

./steamcmd.sh

Exit steam shell by using “quit” command.

Go to your arma3 directory and create upgrade-arma-3 file there.

nano upgrade-arma-3

Write the following line there.

/home/<NAME>/steam/steamcmd.sh +runscript /home/<NAME>/arma3/update-arma-3.txt

Where you obviously replace <NAME> with your name or fix the path with where ever you installed steam/ dir.

Now create permissions for that file.

chmod 755 upgrade-arma-3

Now open the update-arma-3.txt file and write there the following.

// Stop the script if any commands fail
@ShutdownOnFailedCommand 1

// Do not prompt for a password, use the one specified in the login command
@NoPromptForPassword 1

// Login to the given steam account
login <steam login> <steam password>

// Set the directory where A3 is/will be installed
force_install_dir /home/<NAME>/arma3

// Install or update the files for App ID 233780, the A3 server
app_update 233780 validate

// Exit the Steam shell
quit

Again you obviously replace <steam login> <steam password> with your login/password and <NAME> with the proper directory.

Now install ArmA 3 files from steam using upgrade-arma-3 command.

./upgrade-arma-3

At this time it will download whole ArmA 3 game/server files for you. Some of the files have been already prepared for specific linux server use which is nice.

At the time this tutorial was written, the ArmA 3 development branch “beta” is not available for Linux Steam install.

Here you also replace <NAME> with whatever directory you are using. Also note the “logs_pmc/” directory this example uses, you should change this to what directory you prefer.
