Nginx HTTP Server - Fourth Edition

Configuration module

The Nginx configuration module is a simple module enabling file inclusions with the include directive, as previously described in the Organization and inclusions section. The directive can be inserted anywhere in the configuration file and accepts a single parameter—a file path:

include /file/path.conf;
include sites/*.conf; 

If you do not specify an absolute path, the file path is relative to the configuration directory. By default, include sites/example.conf will include the following file:/usr/local/nginx/conf/sites/example.conf
