serve static files

# Serving static files:
# If Nginx could not find the file it will return a 404 page to the user by default.
# But you also can return the directory listing by using autoindex directive

server {
    # `root` directive append URI to the root and then tries to return a file.
    root /var/www/data;
    autoindex on;

    location / {
        # In this location `root` directive is inherited from its parent section which is `server`
    }
    # Request: GET /images/a.png
    #  - Now Nginx tries to find images in this path: /var/www/data/images/a.png
    # Request: GET /images/a/b
    #  - Now Nginx tries to serve this file: /var/www/data/images/a/b/index.html
    location /images/ {
        # In this location `root` directive is inherited from its parent section which is `server`
    }
    # GET /anything/a.mp3
    #  - If URI ends with .mp3 or .mp4 nginx tries to file the file in this path: /var/www/media/
    #  - In this exmaple it tries to serve /var/www/media/a.mp3
    location ~ \.(mp3|mp4) {
        root /var/www/media;
    }
