Now that you know how to manage the service itself, you should take a few minutes to familiarize yourself with a few important directories and files.
Content
/var/www/html: The actual web content, which by default only consists of the default Nginx page you saw earlier, is served out of the/var/www/htmldirectory. This can be changed by altering Nginx configuration files.
Server Configuration
/etc/nginx: The Nginx configuration directory. All of the Nginx configuration files reside here./etc/nginx/nginx.conf: The main Nginx configuration file. This can be modified to make changes to the Nginx global configuration./etc/nginx/sites-available/: The directory where per-site "server blocks" can be stored. Nginx will not use the configuration files found in this directory unless they are linked to thesites-enableddirectory (see below). Typically, all server block configuration is done in this directory, and then enabled by linking to the other directory./etc/nginx/sites-enabled/: The directory where enabled per-site "server blocks" are stored. Typically, these are created by linking to configuration files found in thesites-availabledirectory./etc/nginx/snippets: This directory contains configuration fragments that can be included elsewhere in the Nginx configuration. Potentially repeatable configuration segments are good candidates for refactoring into snippets.
Server Logs
/var/log/nginx/access.log: Every request to your web server is recorded in this log file unless Nginx is configured to do otherwise./var/log/nginx/error.log: Any Nginx errors will be recorded in this log.
