Counter-Strike 2/Dedicated Servers

This page outlines how to setup and run an Counter-Strike 2 Dedicated Server.

Recommended system requirements

Stub

This article or section is a stub. You can help by expanding it.

Linux:

• Minimum RAM: 2GB
• Storage: 33GB
• Requires Glibc 2.31

Note:The Glibc requirement means a minimum of Ubuntu 20.04, Debian 11, or Enterprise Linux 9 is required.

Download the CS2 Dedicated server

Note:The CS2 dedicated server and game client have been merged together (appid 730). Previously the CSGO client (appid 730) and dedicated server (appid 740) were separate.

Important:The total size of Counter-Strike 2 download is approximately 33GB

This describes the process of installing/updating the CS2 dedicated server. These steps are required every time the game is updated. To automate this process for future updates, see SteamCMD#Automating SteamCMD.

1. Download and install SteamCMD.

2. Start SteamCMD. At the Steam> prompt, set your CS2 Dedicated Server install directory.

Bug:On some Linux distributions the path cannot contain any capital letters  [todo tested in ?]

Examples:

• Windows:

force_install_dir c:\cs2-ds\
force_install_dir .\cs2-ds\

• Linux:

force_install_dir /full/path/to/cs2-ds/

3. Install or Update CS2. If this is your first time installing or if you are trying to verify the integrity of the server files:

app_update 730 validate

If this is simply an update to an existing CS2 dedicated server:

app_update 730

4. Once finished, type quit at the Steam> prompt to properly log off of the Steam servers.

Registering Game Server Login Token

Confirm:The server auto generates the GSLT on startup, stores it locally, and renews when able to.

No. GSLT must be created just like with CSGO. Seem to be able to use the same one from CSGO. I was unsure how to add/use it properly. Using +sv_setsteamaccount <TOKEN> on command line. With CSGO you set this in autoexec.cfg

No Steam account token was specified. Logging into anonymous game server account. Connections will be restricted to LAN only. To create a game server account go to http://steamcommunity.com/dev/managegameservers

Starting the Server

Note:For information about ports to be forwarded see the general SRCDS page.

Note:Default gamemode when starting the server is competitive. See #Game_Modes_&_Types for all game modes

Note:You need to add the parameter -dedicated for it to launch the dedicated server, else it launches the game.

Windows

Head to the folder where you downloaded the application and open a terminal there.

Head to the executable for the server that is stored in game/bin/win64/cs2.exe - But don't click on it as it will just launch the game.

In the terminal run the following command to start the server:

.\cs2.exe -dedicated +map de_dust2

Linux

Head to the folder where you downloaded the application.

Head to the executeable that is stored in game/bin/linuxsteamrt64/cs2

Run the following command to start the server:

./cs2 -dedicated +map de_dust2

Tools and Helpers

Docker

If your server is running Docker, you can simply use:

docker run -d --name=cs2 -p 27015:27015 -p 27020:27020 joedwards32/cs2

The container will automatically update the game on startup, so if there is a game update just restart the container.

The config is located within the container here: /home/steam/cs2-dedicated/cs2/cfg

You can find the associated Docker Hub page

CS2 Multiserver

A launch and update script for Linux and WSL to run multiple game servers on one machine. It was originally made to run CS:GO LAN tournaments as painlessly and efficiently as possible.

It includes:

• Guided setup and game update (cs2-server setup, cs2-server update)
• Game files are shared between instances, saving disk space and bandwidth
• Additional control upon launch via environment variables (MAP="de_inferno" cs2-server @lan01 start)
• Console access and support for logfiles

More Info and Download: CS2 Multiserver on GitHub. Testing, feedback and contributions are welcome!

Troubleshooting

Linux

steamservice.so missing/failed to load

This is a common issue with a fairly easy fix.

The reason for this error is that SteamCMD doesnt place the file in the folder it should, as the games typically look for it there. So what you need todo is the following.

Create a symlink (shortcut) for each of the files like this: (run each seprately)

ln -s /home/your_user/.local/share/Steam/steamcmd/linux64/steamclient.so /home/your_user/.steam/sdk64/
ln -s /home/your_user/.local/share/Steam/steamcmd/linux32/steamclient.so /home/your_user/.steam/sdk32/

Replace your_user with the username you are using.

Note:If you are using multiple steam instances make sure the accounts that run them have also done the steps for above.
