Deployment Overview of Counter-Strike 2 Server on Server¶

Prerequisites and Basic Requirements¶

The deployment of the Counter-Strike 2 server requires the following system specifications and configurations:

Operating System: Ubuntu (compatible with apt package manager).
Architecture: Support for both amd64 and i386 architectures is required.
Privileges: Root access or sudo privileges are necessary for installation and configuration.
Domain: The server utilizes the hostkey.in zone.
Ports: The server requires network access for game traffic and management; specific ports are detailed in the Available Ports section.

FQDN of the Final Panel¶

The fully qualified domain name (FQDN) for accessing the server panel follows the format: plane<Server ID>.hostkey.in:<port>

Where:

plane is the configured prefix.
<Server ID> is the unique identifier for the specific server instance.
<port> is the port number assigned for the service.

File and Directory Structure¶

The application and its components are organized within the following directory structure:

Installation Directory: /opt/cs2
Contains the steamcmd tools and the game files.
Game Files: /opt/cs2/game
Contains the Counter-Strike 2 binaries and game data.
Configuration Files: /opt/cs2/game/game/csgo/cfg/cs2server.cfg
Stores the server configuration settings.
Steam SDK: /root/.steam/sdk64
Contains the steamclient.so library required for the server.
Management Script: /root/cs2server.sh
The shell script used to control the server lifecycle.
Log File: /var/log/cs2server.log
Stores runtime logs for the server.
PID File: /tmp/cs2server.pid
Stores the process ID of the running server.
Nginx Configuration: /data/nginx/user_conf.d
Contains custom Nginx configuration files.
Nginx Environment: /data/nginx/nginx-certbot.env
Contains environment variables for the Nginx container.

Application Installation Process¶

The Counter-Strike 2 server is installed using the steamcmd utility. The process involves the following steps:

Repository Configuration: The multiverse repository is added to the system, and the i386 architecture is enabled to support 32-bit libraries.
Package Installation: The steamcmd package is installed via the apt package manager.
SteamCMD Setup: The steamcmd binary is downloaded and extracted to /opt/cs2.
Game Installation: The steamcmd tool is executed to download and validate the Counter-Strike 2 application (App ID 730) into the /opt/cs2/game directory.
Library Configuration: The steamclient.so library is copied from the installation directory to /root/.steam/sdk64.
Configuration Deployment: The server configuration file cs2server.cfg is placed in the game configuration directory.
Management Script Deployment: The cs2server.sh script is installed in /root with executable permissions.

Docker Containers and Their Deployment¶

The deployment includes a Docker container for the Nginx web server and SSL management. The container is defined using a Docker Compose configuration.

Container Details:

Image: jonasal/nginx-certbot:latest
Restart Policy: unless-stopped
Network Mode: host
Environment:
CERTBOT_EMAIL: Set to [email protected]
Additional environment variables are loaded from /data/nginx/nginx-certbot.env.
Volumes:
nginx_secrets: Mounted to /etc/letsencrypt for SSL certificate storage.
/data/nginx/user_conf.d: Mounted to /etc/nginx/user_conf.d for custom Nginx configurations.

The Docker Compose file is located at the path specified in the deployment context, managing the lifecycle of the Nginx service.

Proxy Servers¶

The server utilizes Nginx as a reverse proxy and SSL termination point.

Software: Nginx with Certbot integration.
SSL Management: Automated via the jonasal/nginx-certbot container image.
Custom Domains: Configured through the nginx_secrets volume and user configuration directory.
Configuration Location: Custom Nginx configurations are stored in /data/nginx/user_conf.d.

Permission Settings¶

File and directory permissions are set as follows to ensure proper operation:

Installation Directory (/opt/cs2): 0755 (rwxr-xr-x).
Steam SDK Directory (/root/.steam/sdk64): 0755 with recursive permissions.
Configuration File (/opt/cs2/game/game/csgo/cfg/cs2server.cfg): Owned by root:root with mode 0755.
Management Script (/root/cs2server.sh): Owned by root:root with mode 0755.

Location of Configuration Files and Data¶

Key configuration and data files are located at the following paths:

Server Configuration: /opt/cs2/game/game/csgo/cfg/cs2server.cfg
Management Script: /root/cs2server.sh
Nginx Environment Variables: /data/nginx/nginx-certbot.env
Nginx Custom Configs: /data/nginx/user_conf.d
SSL Certificates: /etc/letsencrypt (mounted volume)
Server Logs: /var/log/cs2server.log
Process ID: /tmp/cs2server.pid

Available Ports for Connection¶

The specific ports for game connection and management are defined within the cs2server.cfg configuration file and the Nginx proxy settings. The Nginx container operates in host network mode, allowing direct access to configured ports.

Starting, Stopping, and Updating¶

The Counter-Strike 2 server is managed using the cs2server.sh script located at /root/cs2server.sh. The script supports the following commands:

Start:
```
/root/cs2server.sh start
```
Initiates the server process in the background, logs output to /var/log/cs2server.log, and saves the PID to /tmp/cs2server.pid.
Stop:
```
/root/cs2server.sh stop
```
Terminates the running server process and removes the PID file.
Restart:
```
/root/cs2server.sh restart
```
Stops the server, waits for 2 seconds, and then starts it again.
Status:
```
/root/cs2server.sh status
```
Checks if the server process is running based on the PID file and reports the current status.

The server binary is executed from /opt/cs2/game/game/bin/linuxsteamrt64/cs2 with the +exec cs2server.cfg argument.
