Some general notes and cheatsheet for nginx

General knowledge

Main config file:
/etc/nginx/nginx.conf

Main site config file:
/etc/nginx/sites-enabled/default

After any change in config, restart the service:
sudo service nginx restart

Reverse proxy configuration

        location / {
                proxy_pass http://127.0.0.1:3000;
        }

or you can do one that's not in the root

        location /files/ {
                rewrite ^/files(.*) $1 break;
                proxy_pass http://127.0.0.1:3000;
        }

Password protection

Setting up very basic file-based password protection is very easy. Replace MyUser with an apropriate username:
sudo sh -c "echo -n 'MyUser:' >> /etc/nginx/.htpasswd"

Then add a password for the user:
sudo sh -c "openssl passwd -apr1 >> /etc/nginx/.htpasswd"

Repeat procedure for as many users as you want, they will all be valid,
to remove a user, just remove their line from the file.

Then add it to your site configuration:

        location / {
                try_files $uri $uri/ =404;
                auth_basic "Restricted Content";
                auth_basic_user_file /etc/nginx/.htpasswd;
        }
