NGINX cheatsheet for Ubuntu Server 20

It’s no secret I love NGINX. I use it in all my projects.

Create a non-root user

adduser ubuntu && usermod -aG sudo ubuntu

Install latest NGINX

sudo add-apt-repository ppa:nginx/stable
sudo apt-get update
sudo apt install nginx
sudo nano /etc/nginx/sites-available/default

Proxy config

server {
    listen 80;
    server_name example.jamesloper.com;
    location / {
        proxy_set_header X-Forwarded-For $remote_addr;
        proxy_set_header Host $http_host;
        proxy_pass http://localhost:3000;
    }
}

Proxy config with WebSockets

map $http_upgrade $connection_upgrade {
    default upgrade;
    '' close;
}

server {
    listen 80;
    server_name example.jamesloper.com;
    root /var/www/html;
    client_max_body_size 100M;

    location / {
        proxy_pass http://127.0.0.1:4000;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection $connection_upgrade;
        proxy_set_header X-Forwarded-For $remote_addr;
        proxy_set_header Host $host;
    }
}

Custom 500 error

Goes inside a server block!

    error_page 500 502 503 504 /500.html;
    location = /500.html {
        root /var/www/html;
        internal;
    }

HTTP redirect block

server {
    listen 80;
    return 301 https://$host$request_uri;
}

Enable SSL

sudo apt install certbot python3-certbot-nginx
certbot --nginx -d db.example.com
