Multi-site WordPress operations

Multi-site hosting amplifies both good patterns and bad ones.

Core patterns

• Hosting multiple WordPress sites on one Apache server
• Using PHP-FPM pools per WordPress site

Common multi-site failures

• PHP version drift on multi-site servers
• Fixing Apache ↔ PHP-FPM socket mismatches

Scaling and growth

• Standardizing server documentation (for future you)

When moving sites or changing URLs, see changing WordPress site URL or hosting folder, migrating a WordPress database between servers, and full WordPress site migration (files + DB + config). If redirects break after a move, see fixing redirect loops after migration.

If you run more than one site on a box, this hub should feel uncomfortably familiar.
