Network Configuration Guide
# Network Configuration Guide
This guide details the network configuration requirements and best practices for running a MediaWiki 1.40 installation. Proper network setup is crucial for performance, security, and accessibility of your wiki. This document is geared towards system administrators and individuals responsible for server maintenance.
1. Network Topology Considerations
The ideal network topology for a MediaWiki installation depends on the expected traffic and user base. A basic setup involves a single web server directly accessible via the internet. Larger installations benefit from load balancing and dedicated database servers. Consider the following:
- Firewall - A firewall is *essential* to protect your wiki from unauthorized access. See Security Best Practices for more details.
- Load Balancer - Distributes traffic across multiple web servers for increased capacity and redundancy. See Load Balancing Setup.
- Database Server - Ideally, the database server (typically MySQL or PostgreSQL) should be located on a separate machine for improved performance and security. Refer to Database Configuration.
- Caching Server - Using a caching server like Varnish or Memcached drastically improves performance by reducing database load. See Caching Strategies.
- Content Delivery Network (CDN) - For globally distributed users, a CDN can significantly reduce latency. See CDN Integration.
- DNS - Correct DNS records are vital for resolving your wiki's domain name to the server's IP address. Ensure both A and potentially AAAA records are configured. See DNS Configuration.
- HTTP/HTTPS - MediaWiki requires a web server, such as Apache or Nginx, to handle HTTP and HTTPS requests. HTTPS is *strongly recommended* for security. See Web Server Configuration.
- SSH - Secure Shell (SSH) is used for remote server administration. Ensure it is properly secured with strong passwords or key-based authentication. See SSH Security.
- SMTP - For sending email notifications (password resets, new user registration, etc.), an SMTP server must be configured. See Email Configuration.
- Keep-Alive - Enable Keep-Alive on your web server to reduce connection overhead. See Apache Keep-Alive and Nginx Keep-Alive.
- TCP Tuning - Adjust TCP parameters (e.g., `tcp_tw_reuse`, `tcp_fin_timeout`) to optimize network performance. See TCP Optimization.
- Network Bandwidth - Ensure sufficient network bandwidth is available to handle peak traffic. Monitor network usage with tools like iftop or nload.
- Database Connection Pooling - Use database connection pooling to reduce the overhead of establishing new connections. See Database Connection Pooling.
- Connectivity Problems - Use `ping` and `traceroute` to diagnose connectivity issues. See Network Troubleshooting.
- DNS Resolution Errors - Verify your DNS records are correct and your DNS servers are reachable.
- Slow Page Load Times - Investigate network latency, server load, and database performance. See Performance Monitoring.
- Firewall Blocking Traffic - Check your firewall rules to ensure traffic on the necessary ports is allowed.

2. Essential Network Services
Several network services must be correctly configured for MediaWiki to function properly.
3. Server Hardware Specifications
The following table outlines recommended hardware specifications for different MediaWiki installation sizes. These are estimates and may vary depending on content complexity and usage patterns.
| Installation Size | Web Server CPU | Web Server RAM | Database Server CPU | Database Server RAM | Storage |
|---|---|---|---|---|---|
| Small ( < 100 Users) | 2 Core | 4 GB | 2 Core | 4 GB | 100 GB SSD |
| Medium (100-1000 Users) | 4 Core | 8 GB | 4 Core | 8 GB | 500 GB SSD |
| Large ( > 1000 Users) | 8+ Core | 16+ GB | 8+ Core | 16+ GB | 1+ TB SSD (RAID) |
4. Network Interface Configuration
Your server(s) will have one or more network interfaces. Proper configuration is essential.
| Interface | IP Address | Netmask | Gateway | DNS Server(s) |
|---|---|---|---|---|
| eth0 (Primary) | 192.168.1.100 | 255.255.255.0 | 192.168.1.1 | 8.8.8.8, 8.8.4.4 |
| eth1 (Optional - Internal) | 10.0.0.10 | 255.255.255.0 | N/A | N/A |
Note: Replace these example values with your actual network configuration. Ensure your firewall allows traffic on the necessary ports (80 for HTTP, 443 for HTTPS, 22 for SSH, 3306 for MySQL, 5432 for PostgreSQL, etc.). See Firewall Configuration.
5. Performance Tuning
Optimizing network settings can significantly improve MediaWiki performance.
6. Security Considerations
Network security is paramount.
| Security Measure | Description | Importance |
|---|---|---|
| Firewall | Blocks unauthorized access to your server. | Critical |
| HTTPS | Encrypts communication between the user and the server. | Critical |
| Intrusion Detection System (IDS) | Detects malicious activity on your network. | High |
| Regular Security Audits | Identifies and addresses vulnerabilities in your system. | High |
| SSH Key Authentication | Securely access your server without passwords. | Medium |
Remember to regularly update your server software and security patches. See Server Security Updates.
