- Game Design Server Configuration
This article details the recommended server configuration for hosting a dedicated Game Design server within our environment. It is geared toward new administrators and aims to provide a clear, technical overview of the necessary components and settings. Proper configuration is vital to ensure a smooth and enjoyable experience for all players. This guide assumes a base installation of a standard Linux distribution (e.g., Ubuntu Server 22.04 LTS) and familiarity with basic server administration tasks. See Server Administration Basics for an introductory guide.
Understanding Game Design Server Requirements
The Game Design server is resource-intensive, particularly regarding CPU and RAM. It utilizes a client-server architecture, where the server handles game logic, world persistence, and player interactions. Insufficient resources can lead to lag, disconnections, and overall poor performance. Before proceeding, ensure you have reviewed the Resource Allocation Policy to understand available server quotas. This server differs from a Database Server in its processing needs. It’s also separate from a Web Server which handles the front-end interface.
Hardware Specifications
The following table outlines the minimum, recommended, and optimal hardware specifications. These specifications are based on supporting up to 64 concurrent players. Performance will degrade significantly with higher player counts without scaling the hardware accordingly. Consult the Performance Scaling Guide for more details.
| Specification | Minimum | Recommended | Optimal |
|---|---|---|---|
| CPU | Intel Xeon E3-1225 v3 or AMD Ryzen 5 1600 | Intel Xeon E5-2680 v4 or AMD Ryzen 7 3700X | Intel Xeon Gold 6248R or AMD EPYC 7543 |
| RAM | 16 GB DDR4 | 32 GB DDR4 | 64 GB DDR4 ECC |
| Storage | 500 GB SSD | 1 TB NVMe SSD | 2 TB NVMe SSD (RAID 1) |
| Network | 1 Gbps Ethernet | 10 Gbps Ethernet | 10 Gbps Ethernet (bonded) |
Software Configuration
The Game Design server requires specific software packages to function correctly. These include the game server binary itself, a Java Runtime Environment (JRE), and potentially a process manager like `systemd`.
Java Runtime Environment (JRE)
The Game Design server is written in Java and requires a compatible JRE. We recommend using the latest OpenJDK version 17. Ensure the `JAVA_HOME` environment variable is correctly set. See Setting Environment Variables for detailed instructions.
Server Startup Script
Create a startup script (e.g., `start_server.sh`) to launch the server with the appropriate Java arguments. This script should handle memory allocation and other critical parameters. A sample script is shown below:
```bash
- !/bin/bash
java -Xms8G -Xmx16G -jar GameDesignServer.jar nogui ```
This script allocates 8GB of initial heap space and a maximum of 16GB. Adjust these values based on your server’s RAM capacity. Remember to make the script executable using `chmod +x start_server.sh`. Refer to the Scripting Guide for more information about bash scripting.
Process Management with Systemd
Using `systemd` ensures the server automatically restarts upon crashes or server reboots. Create a service file (e.g., `gameserver.service`) in `/etc/systemd/system/`:
``` [Unit] Description=Game Design Server After=network.target
[Service] User=gameserver WorkingDirectory=/opt/gameserver ExecStart=/opt/gameserver/start_server.sh Restart=on-failure
[Install] WantedBy=multi-user.target ```
Replace `gameserver` with the appropriate user account and `/opt/gameserver` with the server’s installation directory. Then, enable and start the service:
```bash sudo systemctl enable gameserver.service sudo systemctl start gameserver.service ```
Check the service status with `sudo systemctl status gameserver.service`. See Systemd Service Management for more details.
Firewall Configuration
The Game Design server requires specific ports to be open in the firewall to allow client connections. The default port is 25565.
| Port | Protocol | Description |
|---|---|---|
| 25565 | TCP & UDP | Game Client Connection |
| 22 | TCP | SSH Access (for administration) - RESTRICT ACCESS! |
| 80 | TCP | Web Administration Interface (if enabled) |
Use `ufw` (Uncomplicated Firewall) to configure the firewall. For example, to allow connections on port 25565:
```bash sudo ufw allow 25565 sudo ufw enable ```
Always restrict SSH access to authorized IP addresses only. See Firewall Security Best Practices for further guidance.
Server Configuration File
The Game Design server’s behavior is controlled by a configuration file (e.g., `server.properties`). This file allows you to customize various settings, such as the server name, game mode, maximum players, and more. Understanding these settings is crucial for tailoring the server to your needs. Refer to the Server Configuration Options document for a comprehensive list of available parameters.
Important Configuration Parameters
The following table highlights some essential configuration parameters:
| Parameter | Description | Default Value |
|---|---|---|
| server-name | The name of the server, displayed in the server list. | "My Game Design Server" |
| max-players | The maximum number of players allowed on the server. | 64 |
| gamemode | The game mode to be played on the server. | "Creative" |
| level-name | The name of the world to load. | "world" |
| enable-command-block | Enables or disables command blocks. | false |
Monitoring and Maintenance
Regularly monitor the server’s performance and logs to identify and address potential issues. Use tools like `top`, `htop`, and `tail -f server.log` to monitor CPU usage, memory consumption, and server output. Implement a regular backup schedule to protect against data loss. See Server Backup Procedures for detailed instructions. Consider using a monitoring solution like Nagios Server Monitoring for automated alerts and historical data analysis.
