What are the system requirements for a CS2 server on Linux?
A Counter-Strike 2 server can basically be self-hosted, even on your own computer. However, to ensure a smooth gaming experience for all players, there are some minimum requirements that a Linux host system must meet:- CPU: 4 hardware threads (cores), i.e. Intel Core i5 750 or better
- RAM: 8 GB
- GPU: AMD or Nvidia GPU with GCN or Kepler architecture or better; current Vulkan drivers must be installed
- Storage space: 85 GB
Which CS2 server is right for you?
You can host your CS2 server on your own computer, but this is not recommended for several reasons. Firstly, home internet speed is usually not good enough to provide a smooth gaming experience for all players. Secondly, the server will only be online when the host computer is turned on. And thirdly, from a performance point of view, it is not recommended to host the server on the same device you want to play on.This is why it makes sense to take advantage of a hosting provider so you can ensure that the gaming experience is smooth and consistent for all players.

It is also possible to host your CS2 server on Windows.
Step 1: Install Steam and SteamCMD
First, start the command line tool SteamCMD. If you don’t have it on your system yet, you need to install SteamCMD first. You will also need the Steam client. To do this, enter this command into your shell:sudo apt install steam
bash Note
Don’t run SteamCMD as the root user, as this could cause serious damage. Instead, you should create a separate user account with sudo privileges, which you can then use to execute the following commands.
Step 2: Download CS2 game files
Entersteamcmd
to start SteamCMD. To download the Counter-Strike 2 game files, first log in to your Steam account. To do this, enter the following command into SteamCMD (replace [username] with your Steam username):login [username]
Note
To create a CS2 server, you need to enable Steam Guard in your Steam account.
/path
with the path to the location you want to use):force_install_dir /path
app_update 730 validate
steamclient.so
file is in the ~/.steam/sdk64
directory. If it isn’t there, you will need to create a link to another directory. Check if steamclient.so
exists in the ~/.local/share/Steam/steamcmd/linux64
directory. If so, enter the following command to create the link:ln -s ~/.local/share/Steam/steamcmd/linux64/steamclient.so ~/.steam/sdk64/
bash Tip
If you do not see the folders
.local
and .steam
, have a look in the hidden files section. You can enable this option in File Explorer by pressing [Ctrl] + [H]. If you only see the .local
folder, you still need to install Steam. If you’ve already tried that, it could mean that something went wrong with the installation.Step 3: Generate login token
The next step is to generate a login token. This can be done on the Steam game server account management page. Go to where the downloaded game files are located and then to the configuration fileSteam/steamapps/common/cs2/game/csgo/cfg/server.cfg
. If you did not specify a location when downloading, you should be able to find this file at ~/Steam/steamapps/common/cs2/game/csgo/cfg/server.cfg
. Open the file and copy the following text into it (replace [token]
with the token you just generated):sv_setsteamaccount "[token]"
Step 4: Start the CS2 server
Your server should now be ready to run. Go to the~/Steam/steamapps/common/cs2/game/csgo/bin/linuxsteamrt64
directory and open a terminal window there. Execute the following command in it:./cs2 -dedicated -usercon +game_type 0 +game_mode 1 +map de_overpass -port 27016
bashgame_type
, game_mode
, map
and port
parameters to your liking to get a different game experience or to make the server accessible through a different port. However, when connecting to the server, you must specify the same port as when you started the server. To connect to the server, enter the command connect [IP]:[Port]
in the CS2 console on another computer (with a different Steam account) (replace [IP]
and [Port]
with the IP of the host computer and the port you specified when you started the server). Alternatively, you can save this data in the Steam client under View > Game Server. Tip
Want to play on a different map but you’re not sure what details to enter? You can find the different maps and their names in the
~/Steam/steamapps/common/cs2/game/csgo/maps
folder..gg
, others will take notice of your server and manually setting up the connection to your server will be easy. Get started right away and check whether the domain you want is available with Domain Checker from IONOS!
