Multisite Configuration on Linux App Service

[sanichol]

Hello! I just installed this image on a new Azure App Service and was configuring it for multiple sites.

It works great for my root site. I can add a second site, but unable to access it at all.

Here are my steps:

1. Create a new App Service in Azure (linux)
2. Login to the site to ensure it works.
3. Open FTP cline and add define('WP_ALLOW_MULTISITE', true); to the wp-config.php.
4. Restart App Service
5. Log back into the site and go to tools -> Network Setup & follow the instructions
6. Added these lines to my wp-config.php:

define( 'MULTISITE', true );
define( 'SUBDOMAIN_INSTALL', false );
define( 'DOMAIN_CURRENT_SITE', 'mytempsite.azurewebsites.net' );
define( 'PATH_CURRENT_SITE', '/' );
define( 'SITE_ID_CURRENT_SITE', 1 );
define( 'BLOG_ID_CURRENT_SITE', 1 );

(above the comment "/* That's all, stop editing! Happy blogging. */")
Note: this was the directory multisite and not the subdomain multisite.
7. Restart App Service again
8. Log in
9. The Network is setup and the second site is available (see below)

10. Clicking on the second site results in the following error:
    

What I've Tried:

1. Looking into the Network setup, WordPress has detected an nginx config. However, when I ssh into the machine then run service nginx status I get:

• status: stopped

2. Tried starting the nginx config but I get the following output:

 * ERROR: nginx failed to start

Unsure how to proceed or what to try next.

For anyone looking for the result, there is now a checkbox in the WordPress on Azure App Service for multisite:

This issue can now be closed. Thank you!
