Guide to Install Counter-Strike 2 Server Using LinuxGSM on Linux

This guide will walk you through setting up a Counter-Strike 2 (CS2) server using LinuxGSM on a Linux system.

Prerequisites

• A Linux server (Ubuntu, Debian, CentOS, etc.).
• Basic knowledge of Linux command-line operations.
• Dependencies installed (e.g., curl, wget, tar, lib32gcc-s1).

Step 1: Update Your System

Ensure your system is up to date:

sudo apt update && sudo apt upgrade -y

Step 2: Install Dependencies

Install the required dependencies for SteamCMD and LinuxGSM:

sudo apt install curl wget tar lib32gcc-s1

Step 3: Install SteamCMD

SteamCMD is required to download the CS2 server files.

1. Create a directory for SteamCMD:

   mkdir ~/steamcmd && cd ~/steamcmd

2. Download and extract SteamCMD:

   wget https://steamcdn-a.akamaihd.net/client/installer/steamcmd_linux.tar.gz
   tar -xvzf steamcmd_linux.tar.gz

3. Run SteamCMD to ensure it works:

   ./steamcmd.sh

   Exit SteamCMD by typing quit.

Step 4: Install LinuxGSM

LinuxGSM simplifies the installation and management of game servers.

1. Download and install LinuxGSM:

   wget -O linuxgsm.sh https://linuxgsm.sh && chmod +x linuxgsm.sh

2. Create a CS2 server instance:

   ./linuxgsm.sh cs2server

3. Install the CS2 server:

   ./cs2server install

   This will download and set up the CS2 server files using SteamCMD.

Step 5: Configure the CS2 Server

1. Edit the server configuration file:

   nano ~/lgsm/config-lgsm/cs2server/cs2server.cfg

2. Adjust settings like:
   • hostname: Server name.
   • rcon_password: Remote console password.
   • sv_password: Server password (if you want a private server).
   • map: Default map (e.g., de_dust2).
3. Save and exit the file.

Step 6: Start the CS2 Server

Start the server using LinuxGSM:

./cs2server start

Check the server status:

./cs2server details

Step 7: Open Firewall Ports

Allow traffic on the default CS2 port (UDP 27015):

sudo ufw allow 27015/udp
sudo ufw reload

Step 8: Connect to Your Server

1. Launch Counter-Strike 2 on your PC.
2. Open the console and type:

   connect YOUR_SERVER_IP:27015

   Replace YOUR_SERVER_IP with your server's public IP address.

Optional: Automate Server Startup

To ensure the server starts automatically on system reboot, create a systemd service:

1. Create a service file:

   sudo nano /etc/systemd/system/cs2server.service

2. Add the following content:

   [Unit]
   Description=Counter-Strike 2 Server
   After=network.target
   
   [Service]
   User=YOUR_USERNAME
   WorkingDirectory=/home/YOUR_USERNAME
   ExecStart=/home/YOUR_USERNAME/cs2server start
   ExecStop=/home/YOUR_USERNAME/cs2server stop
   Restart=always
   
   [Install]
   WantedBy=multi-user.target

   Replace YOUR_USERNAME with your Linux username.

3. Enable and start the service:

   sudo systemctl enable cs2server
   sudo systemctl start cs2server

Troubleshooting

• Check logs in ~/lgsm/log for errors.
• Ensure SteamCMD and LinuxGSM are up to date.
• Verify that the firewall is not blocking the server.

Additional Notes

• LinuxGSM is actively maintained. Check the official documentation for the latest updates.
• Customize your server further by editing the server.cfg file located in the CS2 server directory.

Enjoy Your CS2 Server!
