You probably already know how to install and manage nginx and wanting to get familiar with important directories.
Root Directory :
This directory servers all the pages by default for nginx
/var/www/html you can upload all your own website files etc in this /var/www/html directory.
Server Configurations Directories :
/etc/nginx: The Nginx configuration directory. All of the Nginx configuration files reside here.
/etc/nginx/nginx.conf: The main Nginx configuration file. you can modify this 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 the
sites-enableddirectory. 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 the
/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 Status 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: You can see all the server side errors in this file.
