Hosting a Linux Server – DayZ

⚠

Do not run the server as root! This way, if your DayZ server is compromised, the attacker will find it more difficult to access the rest of the operating system.
All actions in this guide were performed as a normal user or under sudo.

Download SteamCMD

Debian:

sudo apt-get install lib32gcc-s1

RHEL:

sudo yum install glibc.i686 libstdc++.i686

Arch Linux:

sudo pacman -Syy glibc lib32-glibc nano

After installing these packages, do the following:

mkdir -p ~/servers/steamcmd && cd ~/servers/steamcmd
curl -sqL "https://steamcdn-a.akamaihd.net/client/installer/steamcmd_linux.tar.gz" | tar zxvf -

cd ~/servers/dayz-server/
ln -s ~/servers/dayz-server/steamapps/workshop/content/221100/1559212036 ~/servers/dayz-server/1559212036
ln -s ~/servers/dayz-server/steamapps/workshop/content/221100/1564026768 ~/servers/dayz-server/1564026768
ln -s ~/servers/dayz-server/steamapps/workshop/content/221100/1559212036/keys/* ~/servers/dayz-server/keys/
./DayZServer -config=serverDZ.cfg -port=2301 "-mod=1559212036;1564026768;" -BEpath=battleye -profiles=profiles -dologs -adminlog -netlog -freezecheck
