  1. Manual:Configuration settings

This article details the configuration settings available in MediaWiki 1.40, aimed at users new to wiki administration. Understanding these settings is crucial for tailoring your wiki to specific needs, enhancing performance, and ensuring security. This guide will cover the primary configuration file, `$wgConfigCacheType`, important settings categories, and common troubleshooting steps.

Introduction to `LocalSettings.php`

The heart of MediaWiki configuration lies within the `LocalSettings.php` file. This file, located in the root directory of your MediaWiki installation, contains PHP code defining various settings that control the wiki's behavior. It’s created during the initial installation process, but can be modified afterward to adjust the wiki’s functionality. It's **extremely** important to back up this file before making any changes. Incorrect configuration can lead to a broken wiki. Never edit this file directly from a web browser; always use a text editor or an FTP client.

Basic Configuration Concepts

Before diving into specific settings, let's understand some core concepts:

  • **Variables:** Settings are defined as PHP variables (e.g., `$wgTitle = "My Wiki";`).
  • **Comments:** Lines starting with `//` are comments and are ignored by the PHP interpreter. Use comments liberally to explain your changes.
  • **Case Sensitivity:** PHP is case-sensitive. `$wgTitle` is different from `$wgtitle`.
  • **Quotes:** String values must be enclosed in single (`'`) or double (`"`) quotes. Double quotes allow variable interpolation (e.g., `"Hello, $wgTitle"`).
  • **Boolean Values:** `true` and `false` are used for boolean settings. You can also use `1` for true and `0` for false.

The `$wgConfigCacheType` Setting

One of the most important settings for performance is `$wgConfigCacheType`. This setting determines how MediaWiki caches the configuration settings read from `LocalSettings.php`.

  • `'cache'` (default): Uses the standard PHP caching mechanism. Simple to set up, but can be slower for large wikis.
  • `'redis'`: Uses a Redis server for caching. Significantly faster than the default, especially for high-traffic wikis. Requires a Redis server to be installed and configured. See Manual:Redis for more information.
  • `'memcached'`: Uses a Memcached server for caching. Another fast option, similar to Redis. Requires a Memcached server to be installed and configured.
  • `'apc'`: Uses APC (Alternative PHP Cache) for caching. Requires APC to be installed and enabled. Often used in shared hosting environments.
  • `'eaccelerator'`: Uses eAccelerator for caching. Requires eAccelerator to be installed and enabled. Less common now than APC.

Choosing the right `$wgConfigCacheType` can dramatically improve wiki performance. For most wikis, `'redis'` or `'memcached'` are recommended if available.

Key Configuration Categories

The `LocalSettings.php` file can be logically divided into several categories.

1. Site Identification

These settings define the basic identity of your wiki.

  • `$wgSitename`: The name of your wiki, used in page titles and elsewhere. (e.g., `$wgSitename = "My Awesome Wiki";`)
  • `$wgMetaDirectory`: The directory where MediaWiki's core files are located (relative to the web server's document root). Usually `/`.
  • `$wgScriptPath`: The path to the `index.php` file (relative to the web server's document root). Usually `/`.
  • `$wgUploadDirectory`: The directory where uploaded files are stored. (e.g., `$wgUploadDirectory = "/images";`)
  • `$wgUploadPath`: The URL path to the upload directory. (e.g., `$wgUploadPath = "/images";`)

2. Database Settings

These settings configure the connection to your wiki's database.

  • `$wgDBtype`: The database type (e.g., `'mysql'`, `'postgresql'`, `'mysqli'`).
  • `$wgDBserver`: The database server hostname or IP address.
  • `$wgDBname`: The name of the database.
  • `$wgDBuser`: The database username.
  • `$wgDBpassword`: The database password.
  • `$wgDBtableprefix`: A prefix to add to all database table names. Useful for running multiple wikis on the same database.

Incorrect database settings will prevent your wiki from functioning. Double-check these carefully.

3. Authentication and User Accounts

These settings control user login and account creation.

  • `$wgAllowEmailLogin`: Whether to allow users to log in with their email address.
  • `$wgAllowCreateAccount`: Whether to allow new users to create accounts.
  • `$wgNewAccountMailText`: The email sent to new users upon account creation.
  • `$wgPasswordSalt`: A salt used to hash passwords. **Important:** Change this from the default value for security reasons.
  • `$wgAuthTokenExpiration`: How long authentication tokens are valid for (in seconds).

Consider enabling two-factor authentication (see Manual:Two-factor authentication for enhanced security.

4. Wiki Features

This category controls various wiki features.

  • `$wgEnableEmail`: Whether to enable email functionality (e.g., sending notifications).
  • `$wgEnableCategories`: Whether to enable categories.
  • `$wgEnableTalkPages`: Whether to enable talk pages.
  • `$wgEnableWikiFarm`: Whether to enable wiki farm functionality (creating subwikis).
  • `$wgUseTrackbacks`: Whether to enable trackbacks.
  • `$wgParserCacheType`: Controls how the parser cache is handled. Similar to `$wgConfigCacheType`, consider using `'redis'` or `'memcached'` for performance.

5. Security Settings

These settings enhance the security of your wiki.

  • `$wgSecretKey`: A secret key used for various security purposes. **Important:** Change this from the default value.
  • `$wgCookiePath`: The path for wiki cookies.
  • `$wgCookieDomain`: The domain for wiki cookies.
  • `$wgCookieSecure`: Whether to require cookies to be transmitted over HTTPS.
  • `$wgRateLimits`: Configure rate limits to prevent abuse. See Manual:Rate limiting for details.
  • `$wgSpamRegex`: Regular expressions to detect and block spam.

6. Appearance and User Interface

These settings control the look and feel of your wiki.

  • `$wgDefaultSkin`: The default skin for the wiki. (e.g., `$wgDefaultSkin = 'Vector';`)
  • `$wgLogo`: The URL or path to the wiki logo.
  • `$wgFavicon`: The URL or path to the favicon.
  • `$wgDisableAtomicWrites`: Disables atomic writes. Can improve performance under some circumstances but may lead to data corruption if the server crashes during a write operation.

7. Extensions

This is where you include and configure extensions.

  • `wfLoadExtension()`: This function is used to load extensions. (e.g., `wfLoadExtension( 'SemanticMediaWiki' );`)
  • Extension-specific settings: Many extensions have their own configuration settings that must be defined in `LocalSettings.php`. Refer to the extension's documentation for details.

Common Troubleshooting Steps

  • **Error Messages:** Pay close attention to any error messages displayed on the wiki. They often provide clues about the problem. Check the wiki's error log for more detailed information.
  • **PHP Errors:** Enable PHP error reporting to display errors on the screen. Add the following lines to `LocalSettings.php` (remove them after debugging):
   ```php
   ini_set( 'display_errors', 1 );
   ini_set( 'error_reporting', E_ALL );
   ```
  • **Caching Issues:** If you've made changes to `LocalSettings.php` and they aren't reflected on the wiki, try clearing the cache. The method for clearing the cache depends on your `$wgConfigCacheType` setting. Using Redis or Memcached typically requires clearing the cache directly on the server.
  • **Database Connection Errors:** Double-check your database settings. Ensure that the database server is running and that the username and password are correct.
  • **Permissions Errors:** Ensure that the web server has the necessary permissions to read and write to the wiki's files and directories.
  • **Extension Conflicts:** If you're experiencing problems after installing an extension, try disabling it to see if that resolves the issue. Check the extension's documentation for known conflicts.

Advanced Configuration Considerations

  • **Load Balancing:** For high-traffic wikis, consider using a load balancer to distribute traffic across multiple servers. See Manual:Load balancer for details.
  • **HTTPS:** Always configure your wiki to use HTTPS for secure communication.
  • **Regular Backups:** Regularly back up your wiki's files and database to prevent data loss.
  • **Monitoring:** Monitor your wiki's performance and resource usage to identify potential problems.
