What is WordPress Multisite?
WordPress Multisite (WPMS) is a feature that allows you to create a network of multiple websites using a single WordPress installation and database. All sites share the same core WordPress files, but each has its own content, users, and themes/plugins.
Enable Multisite
# In wp-config.php, above 'That's all, stop editing' line:
define('WP_ALLOW_MULTISITE', true);
# After running Tools > Network Setup in WordPress admin,
# add the provided code to wp-config.php and .htaccessSubdomain vs Subdirectory Networks
Subdomain: each site gets its own subdomain (site1.yourdomain.com). Subdirectory: each site is a path (yourdomain.com/site1). Subdomains provide better separation but require wildcard DNS. Subdirectories are simpler to configure.
FAQ
Can each Multisite site have its own theme and plugins?
Yes. The network admin activates themes and plugins globally, then individual site admins can activate/deactivate them per site. Some plugins can be forced active on all sites.
