Subdirectory Multisite in a Subdirectory

A proof-of-concept for WordPress subdirectory multisite in a subdirectory of the web root:

• Web server root at ./web.
• WordPress added as a Composer dependency at ./web/wp.
• WordPress multisite configured as subdirectory install.

See nginx.conf for the relevant Nginx configuration and specifically the rewrite rules.

Requirements

• Docker
• PHP and Composer

Setup

1. Install Composer dependencies:

    composer install
   

2. Start the server environment:

    composer start
   

3. Setup the WP sub-directory network:

    composer setup
   

Visit the environment at subdir.wpenv.net or subdir.wpenv.net:8033 to view PHPMyAdmin.

Login at subdir.wpenv.net/wp-login.php using admin as username and password as password.

Create a new site on the network such as subdir.wpenv.net/example:

composer cli -- wp site create --slug=example

and visit its admin area at subdir.wpenv.net/example/wp-admin/ while the site is available at subdir.wpenv.net/example/.
