Launch a Counter Strike: Global Offensive (CS:GO) server on Ubuntu 14.04

Counter Strike: Global Offensive (CS:GO) is a first-person shooter by Valve. Hosting your own server gives you full control over your game and game modes, so you can play the exact flavor of CS:GO you want. This guide contains instructions on how to download the dedicated server and launch the game server.

Before You Begin

1. You will need a Steam account and a copy of Counter Strike: Global Offensive . A game server token is required to host a public CS:GO server. Without the token, client connections are restricted to the LAN only.

2. Complete our guide: Install SteamCMD for a Steam Game Server . This will get SteamCMD installed and running on your Linode and this guide will pick up where the SteamCMD page leaves off.

Prerequisites for Counter-Strike: Global Offensive

From the SteamCMD guide, one additional step is needed specifically for CS:GO.

1. Replace a firewall rule to slightly extend the port range available to the game. This command assumes that you have only the iptables rules in place from the SteamCMD guide:

   sudo iptables -R INPUT 5 -p udp -m udp --sport 26900:27030 --dport 1025:65355 -j ACCEPT
   

Install Counter Strike: Global Offense

1. Be sure you are in the directory ~/Steam, then access the Steam> prompt.

   cd ~/Steam && ./steamcmd.sh
   

2. From the SteamCMD prompt, login anonymously:

   login anonymous
   

   Or log in with your Steam username:

   login example_user
   

3. Install CS:GO to the Steam user’s home directory:

   force_install_dir ./csgo-ds
   app_update 740 validate
   

   This can take some time. If the download looks as if it has frozen, be patient. Once the download is complete, you should see this output:

   Success! App '740' fully installed.
   
   Steam>
   

4. Exit SteamCMD.

   quit
   

   Note

   To update CS:GO, run the above 4 commands again.

Game Server Login Token

CS:GO requires a server token unless you want to limit players to only clients connecting from within the server’s LAN. This requires having a Steam account and owning CS:GO. See Valve’s CS:GO wiki for more info on the GSLT.

Configure the Server

1. Create a file called server.cfg using your preferred text editor. Choose a hostname and a unique RCON password that you don’t use elsewhere.

   File: ~/Steam/csgo-ds/csgo/cfg/server.cfg

   1 2 3 4 5 6 7 8

   hostname "server_hostname" sv_password "server_password" sv_timeout 60 rcon_password "rcon_password" mp_autoteambalance 1 mp_limitteams 1 writeid writeip

   For an extensive list of server.cfg options, see this page .

2. Create a startup script for CS:GO with the contents given below. Be sure to replace YOUR_GSLT in the script’s command with your game server login token.

   File: ~/startcsgo.sh

   1 2 3 4

   #!/bin/sh cd ./Steam/csgo-ds screen -S "Counter-Strike: Global Offensive Server" ./srcds_run -game csgo -usercon +game_type 0 +game_mode 1 +mapgroup mg_bomb +map de_dust2 +sv_setsteamaccount YOUR_GSLT -net_port_try 1

   When run, the script will change directories to ~/Steam/csgo-ds and execute a Dust2 server in competitive game mode in a Screen session. For more startup modes and game options, see Valve’s CS:GO wiki .

3. Make the script executable:

   chmod +x ~/startcsgo.sh
   

Start the Server

1. Now that your server is installed and configured, it can be launched by running the startcsgo.sh script from your steam user’s home directory.

   cd ~/ && ./startcsgo.sh
   

   Important

   From this point, do not press the Control+C keys while in the console unless you want to stop CS:GO.

2. To detach from the screen session running the server console, press these two key combinations in succession:

   Control+A
   Control+D

3. To bring the console back, type the following command:

   screen -r
   

4. To stop the server, bring back the CS:GO console and press CONTROL + C.

2. Once launched, go to Play and click Browse Community Servers.

3. Click on the Favorites tab and then click Add a Server at the bottom.

4. Type in the IP address of your Linode and click Add this address to favorites.
