Multisite

Overview

WordPress Multisite is a feature built into WordPress that allows us to run multiple websites from a single WordPress installation. Here’s a breakdown of how it works under the hood:

1. Single Codebase, Multiple Sites

Only one set of WordPress core files.
All sites share plugins and themes (though individual sites can enable/disable them).

2. Database Structure

All sites share a single database, but WordPress creates separate tables per site.
Table structure:
- Main site: wp_options, wp_posts, etc.
- Sub-sites: wp_2_options, wp_2_posts, wp_3_options, etc.
Global/shared tables include:
- wp_users and wp_usermeta (users are shared across the network)
- wp_site, wp_blogs, wp_sitemeta for network management

3. Domain Mapping

Sites can be:
- Subdomains: site1.example.com
- Subdirectories: example.com/site1
With a plugin or custom configuration, you can map custom domains (e.g., site1.com, site2.net).

4. .htaccess and wp-config.php

Multisite modifies both:
- wp-config.php: defines MULTISITE, SUBDOMAIN_INSTALL, and other constants.
- .htaccess: rewrites URLs to route traffic correctly to each site.

5. Admin Interface

Two admin layers:
- Network Admin (/wp-admin/network): For managing the entire network (users, themes, plugins, sites).
- Site Admin: Each site has its own admin dashboard (/wp-admin) with scoped permissions.

6. Security and Isolation

Sites are not fully isolated like containerized apps.
Plugins and themes are network-wide, so a faulty plugin can affect all sites.
User roles and capabilities can be restricted per site, but full sandboxing is not native.

7. Performance and Caching

Because of shared resources and a single DB, high-traffic multisites often need:
- Advanced object caching (e.g., Redis)
- CDN and page caching
- DB scaling (e.g., using HyperDB or shard-based plugins)
