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 apt-get install software-properties-common
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
sudo certbot --nginx -d db.example.com
