  1. OVHcloud Server Configuration for MediaWiki 1.40

This article details configuring an OVHcloud server for running MediaWiki 1.40. It is aimed at newcomers seeking a robust and scalable hosting solution. OVHcloud offers a variety of server options, but this guide will focus on general principles applicable across their offerings, with some specific notes for common setups. This guide assumes you have basic command-line familiarity and a working knowledge of Linux server administration.

Understanding OVHcloud Offerings

OVHcloud provides several server options suitable for MediaWiki. The most common include:

  • **Public Cloud Instances:** Flexible, scalable, and pay-as-you-go. Ideal for projects with fluctuating traffic. Requires more configuration.
  • **Dedicated Servers:** Provide exclusive hardware resources. Good for high-traffic wikis or those requiring specific hardware configurations. More expensive but offer greater control.
  • **VPS (Virtual Private Servers):** A middle ground between Public Cloud and Dedicated Servers, offering a balance of cost and control.

Choosing the right option depends on your wiki's size, traffic, and budget. For a small to medium-sized wiki, a VPS is often a good starting point. For larger wikis, consider Public Cloud Instances or Dedicated Servers. See Choosing a Hosting Provider for more general advice.

Server Specifications and Recommendations

Here's a table outlining recommended server specifications for different wiki sizes:

Wiki Size CPU RAM Storage (SSD) Bandwidth
Small (Under 10,000 pages) 2 vCores 4 GB 80 GB 1 TB
Medium (10,000 - 100,000 pages) 4 vCores 8 GB 160 GB 3 TB
Large (Over 100,000 pages) 8+ vCores 16+ GB 320+ GB 5+ TB

These are starting points. Monitor your server's resource usage regularly using tools like `top`, `htop`, or OVHcloud's monitoring dashboard and adjust accordingly. Consider using a Database server separate from the web server for better performance, especially for larger wikis.

Software Installation and Configuration

The core software stack for MediaWiki includes:

  • **Operating System:** A Linux distribution like Ubuntu Server, Debian, or CentOS. Ubuntu is often preferred for its ease of use and large community support.
  • **Web Server:** Apache or Nginx. Nginx is often more performant for static content and can handle higher concurrency.
  • **Database Server:** MySQL or MariaDB. MariaDB is a popular, open-source fork of MySQL.
  • **PHP:** The scripting language MediaWiki is built upon. MediaWiki 1.40 requires PHP 7.3 or higher.
  • **PHP Extensions:** Essential extensions for MediaWiki functionality.

Here's a table detailing the required PHP extensions:

PHP Extension Description
php-cli Command-line interface for PHP
php-mysql MySQL database support
php-gd Image manipulation library
php-mbstring Multibyte string support
php-xml XML processing support
php-json JSON support
php-curl Client URL library
php-intl Internationalization support
php-zip ZIP archive support

Installation commands will vary depending on your chosen Linux distribution. For example, on Ubuntu: `sudo apt update && sudo apt install apache2 mariadb-server php php-cli php-mysql php-gd php-mbstring php-xml php-json php-curl php-intl php-zip`

Security Considerations

Securing your server is crucial. Implement the following measures:

  • **Firewall:** Configure a firewall (e.g., `ufw` on Ubuntu) to allow only necessary ports (80 for HTTP, 443 for HTTPS, 22 for SSH - restrict SSH access to specific IP addresses). See Firewall configuration.
  • **SSL/TLS:** Enable HTTPS using a certificate from Let's Encrypt or a commercial provider. See Setting up SSL.
  • **Regular Updates:** Keep your operating system and all software packages up-to-date with the latest security patches. Use `sudo apt update && sudo apt upgrade` on Debian/Ubuntu.
  • **MediaWiki Security:** Follow the security recommendations outlined in the MediaWiki security documentation.
  • **Database Security:** Use strong passwords for your database user and restrict access to the database server.

Here's a table summarizing key security practices:

Security Measure Description Priority
Firewall Configuration Restrict network access to essential ports. High
SSL/TLS Encryption Secure communication between server and clients. High
Regular Software Updates Patch security vulnerabilities. High
Strong Passwords Protect database and server accounts. High
MediaWiki Security Practices Implement MediaWiki-specific security measures. Medium

Optimizing Performance

  • **Caching:** Enable caching mechanisms like APC, Memcached, or Redis to reduce database load.
  • **Database Optimization:** Regularly optimize your MariaDB/MySQL database using tools like `OPTIMIZE TABLE`.
  • **OPcache:** Ensure PHP OPcache is enabled for faster script execution.
  • **HTTP Compression:** Enable Gzip compression in your web server configuration to reduce bandwidth usage.
  • **Content Delivery Network (CDN):** Consider using a CDN to serve static content from geographically distributed servers. See CDN integration.

Remember to monitor your server's performance and adjust your configuration as needed. Regularly review your server logs for errors or performance bottlenecks. Performance tuning is a continuous process.
