7 Days To Die work very well as Client or Server instance on Linux.  Player can choice single or multiplay on own local PC, and can to play on dedicade servers. Here is example how really fast make dedicade 7dtd server on Debian 9 GNU/Linux.

At the beginning of my trip I wrote my script, but later I found the perfect script from Allocs and me just make Debian package (7dtd-installer). I add package in my Debian repository and if wont to make 7dtd server You can with:

echo "# Jurišić Stretch " >> /etc/apt/sources.list
echo "deb http://apt.jurisic.org/debian/ stretch main contrib non-free" >> /etc/apt/sources.list
wget -q http://apt.jurisic.org/Release.key -O- | apt-key add -
apt-get update
apt-get install 7dtd-installer

That is all, installer will bring Allocs script (bootstrap.sh) and start automatic installation.
