Default NGINX File for a Drupal 6/7/8 Site on a Virtualmin Server

Background

Although NGINX doesn’t have the concept of .htaccess, getting Drupal 8 working on a Virtualmin NGINX certainly is possible. You have to take the default NGINX conf file produced for every new NGINX virtual server, and then append the official NGINX recipe to the end. There are three other changes also documented below.

This guide has mostly been tested for Drupal 8, but it might also work with other versions. The three changes to be made are:

1. Ignore root directory path location.

In the Drupal NGINX recipe, ignore `root /var/www/drupal8; ## <– Your only path reference.` as this will already be set for you in Virtualmin.

The line from the default recipe that you don’t need, is the one that says root (3rd line from the top). The reason why you can exclude this from the official NGINX recipe is because Virtualmin already has it in and then some (DOCUMENT_ROOT & SCRIPT_FILENAME).

2. In the Drupal NGINX recipe, the socket location can be ignored. This has already been set in Virtualmin. The line to commented out is this one:

#fastcgi_pass unix:/var/run/php/php7.0-fpm.sock;

3. There is one other change that you might have to do. If you get An AJAX HTTP error occurred 404 for core/authorize.php/core/authorize.php then make a note of the rewrite addition below as per comment in this article.

rewrite ^/core/authorize.php/core/authorize.php(.*)$ /core/authorize.php$1;

Continuing on, if you look below, everything below fastcgi_read_timeout 90; is the official recipe including the above line and everything above fastcgi_read_timeout 90; is the default Virtualmin setup. We included a bigger timeout value as an example of a configuration value that one might do post Drupal install.

Without further adieu, here it is:
