  1. Nginx Configuration for MediaWiki

This article details configuring Nginx as a reverse proxy and web server for a MediaWiki 1.40 installation. Nginx is a popular choice due to its performance, stability, and low resource consumption. This guide assumes you have a basic understanding of server administration and Linux command-line interface. It also assumes you have a functioning PHP installation and a MariaDB or MySQL database server set up for MediaWiki.

== Why Use Nginx with MediaWiki?

While MediaWiki can be served directly by Apache, using Nginx as a reverse proxy provides several benefits:

  • **Improved Performance:** Nginx excels at serving static content and efficiently handling concurrent connections.
  • **Load Balancing:** Nginx can distribute traffic across multiple backend MediaWiki instances for increased scalability.
  • **Security:** Nginx can act as a first line of defense against common web attacks.
  • **SSL/TLS Termination:** Nginx can handle SSL/TLS encryption and decryption, reducing the load on the MediaWiki server.
  • **Caching:** Nginx can cache frequently accessed content, further improving performance.

== Prerequisites

Before you begin, ensure you have:

  • A server with a Linux distribution (e.g., Ubuntu, Debian, CentOS).
  • Nginx installed and running. Instructions vary depending on your distribution.
  • PHP installed with the necessary extensions for MediaWiki (e.g., `php-mysql`, `php-gd`, `php-xml`).
  • MediaWiki 1.40 installed and configured, but *not* directly accessible via the web.
  • Root or sudo access to the server.


== Basic Nginx Configuration

The core of the Nginx configuration involves creating a server block that listens for incoming requests and proxies them to the MediaWiki backend. Here's a basic configuration example:

```nginx server { 

   listen 80;
   server_name your.mediawiki.domain;

   location / {
       proxy_pass http://127.0.0.1:8080;  # Assuming MediaWiki runs on port 8080
       proxy_set_header Host $host;
       proxy_set_header X-Real-IP $remote_addr;
       proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
       proxy_set_header X-Forwarded-Proto $scheme;
   }

} ```

Replace `your.mediawiki.domain` with your actual domain name and `8080` with the port MediaWiki is listening on. This basic configuration forwards all requests to the MediaWiki server running on the same machine.

== Advanced Configuration Options

Several advanced options can enhance the Nginx configuration for MediaWiki:

  • **SSL/TLS:** Enable HTTPS by configuring SSL/TLS certificates.
  • **Caching:** Cache static assets (images, CSS, JavaScript) to reduce server load.
  • **Gzip Compression:** Compress responses to reduce bandwidth usage.
  • **Security Headers:** Add security headers to protect against common web vulnerabilities.
  • **File Serving:** Serve static files directly from Nginx for optimal performance.

== Key Configuration Parameters

Here's a table detailing important Nginx configuration parameters for MediaWiki:

Parameter Description Default Value
`listen` The port Nginx listens on. 80
`server_name` The domain name or IP address Nginx responds to. `_` (any hostname)
`proxy_pass` The URL of the backend MediaWiki server. N/A
`proxy_set_header` Sets HTTP headers to be passed to the backend server. N/A
`client_max_body_size` The maximum allowed size of the client request body. Important for file uploads. 1MB
`gzip` Enables Gzip compression for responses. Off

== Example: Configuring SSL/TLS

To enable SSL/TLS, you'll need an SSL certificate. Let's Encrypt is a popular free option. Here's an example configuration:

```nginx server { 

   listen 443 ssl;
   server_name your.mediawiki.domain;

   ssl_certificate /etc/letsencrypt/live/your.mediawiki.domain/fullchain.pem;
   ssl_certificate_key /etc/letsencrypt/live/your.mediawiki.domain/privkey.pem;

   location / {
       proxy_pass http://127.0.0.1:8080;
       proxy_set_header Host $host;
       proxy_set_header X-Real-IP $remote_addr;
       proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
       proxy_set_header X-Forwarded-Proto $scheme;
   }

}

server { 

   listen 80;
   server_name your.mediawiki.domain;
   return 301 https://$host$request_uri;

} ```

This configuration redirects all HTTP traffic to HTTPS and uses the specified SSL certificates.

== Example: Configuring Caching

Nginx can cache static assets to improve performance. Here is an example snippet:

```nginx location ~* \.(jpg|jpeg|png|gif|css|js|ico)$ { 

   expires 30d;
   add_header Cache-Control "public";

} ```

This configuration sets a cache expiry of 30 days for common static file types.

== Important Considerations and Troubleshooting

  • **`$wgServer` in LocalSettings.php:** In your MediaWiki `LocalSettings.php` file, ensure the `$wgServer` variable is set correctly to your public Nginx address (e.g., ` $wgServer = "https://your.mediawiki.domain";`).
  • **`$wgScriptPath` in LocalSettings.php:** Verify `$wgScriptPath` is set appropriately. Usually, this is `/`.
  • **File Uploads:** Increase `client_max_body_size` in your Nginx configuration if you experience issues with file uploads.
  • **Permissions:** Ensure Nginx has the necessary permissions to access the MediaWiki files.
  • **Logs:** Check the Nginx error logs (`/var/log/nginx/error.log`) and MediaWiki logs for troubleshooting.
  • **PHP-FPM:** If you're using PHP-FPM, ensure it's properly configured and running.

== Nginx Configuration File Locations

Operating System Default Nginx Configuration Directory
Ubuntu/Debian `/etc/nginx/sites-available/` and `/etc/nginx/sites-enabled/`
CentOS/RHEL `/etc/nginx/conf.d/`
Fedora `/etc/nginx/conf.d/`

== Performance Tuning

Parameter Description Suggested Value
`worker_processes` Number of worker processes. Number of CPU cores
`worker_connections` Maximum number of connections per worker process. 1024 - 4096
`keepalive_timeout` Timeout for keep-alive connections. 65
`proxy_buffer_size` Initial buffer size for proxying. 128k
`proxy_buffers` Number and size of proxy buffers. 4 256k
