[CentOS 7] How to install a Arma 3 server

Please note, our virtual dedicated servers are unmanaged, these guides are just to get you started

You’re going to first start of by updating Ubuntu to ensure the latest bug and security updates are patched.

sudo yum upgrade

You will next need to install some dependencies for Arma 3 and steamcmd to use, we will also be installing screen

sudo yum install glibc.i686 libstdc++.i686 gcc screen -y

You will now need to open the following ports to allow your players to connect

firewall-cmd --zone=public --add-port=2302/udp --permanent

firewall-cmd --zone=public --add-port=2303/udp --permanent

firewall-cmd --zone=public --add-port=2304/udp --permanent

firewall-cmd --zone=public --add-port=2305/udp --permanent

firewall-cmd --zone=public --add-port=2306/udp --permanent

firewall-cmd --reload

We advise against using the root user for security reasons, so we will be creating a new user for the server

sudo adduser arma3

passwd arma3

Now we can switch to our new user to start creating the server

su arma3

We will now create a new directory for SteamCMD

mkdir ~/steamcmd && cd ~/steamcmd

Start the download of the steamcmd installer by entering the following:

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

We can extract the contents of the steamcmd installer simply by entering:

tar -xvzf steamcmd_linux.tar.gz

Running the SteamCMD command line is the next step. Once the extraction has completed we can start with the download of the Arma 3 server files.:

./steamcmd.sh

You will then need to login to Steamcmd using a valid steam account (Note this does not need to have Arma installed, Valve recommends using a blank steam account for this)

login myusername

Next we will specify where to install the server:

force_install_dir ./arma3/

Next we will download the Arma 3 Linux dedicated server files:

app_update 233780 validate

We can now exit SteamCMD:

exit

We will now create the directories for the profile files and Arma3.cfg file

mkdir -p ~/".local/share/Arma 3" && mkdir -p ~/".local/share/Arma 3 - Other Profiles"

To launch the server run the following

script /dev/null

screen -S armaserver

cd arma3

./arma3server -name=server -config=server.cfg

You can then exit screen using Control + A + D

[Configuring the server]

You can edit most the server settings in the config file

cd ~/steamcmd/arma3

vi server.cfg
