NGINX Server

Configuring a NGINX Reverse-Proxy.

Installing Nginx

sudo apt update
sudo apt install nginx

Firewall Configuration

Options avaliable:

  • Nginx Full > HTTP (port 80) and HTTPS (port 433) are accessible.
  • Nginx HTTPS > Only HTTPS (port 433) is accessible.
  • Nginx HTTP > Only HTTP (port 80) is accessible.
sudo ufw allow 'Nginx Full'

Check your Web Server

systemctl status nginx

If everthing worked fine, the initial Nginx HTML will be visible on:

http://your_ip_address

Configure Nginx

Configure Nginx to redirect for your app, based on any domain.com.

server {
    listen      80;
    listen      [::]:80;
    server_name domain.com;

    location / {
        proxy_pass http://localhost:${app_port};
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection 'upgrade';
        proxy_set_header Host $host;
        proxy_cache_bypass $http_upgrade;
    }
}

Here you can redirect a request for your domain.com to a localhost port, where could be running your app.

Cerbot

Certbot is an easy-to-use automatic client that fetches and deploys SSL/TLS certificates for your web server. Certbot was developed by EFF and others as a client for Let’s Encrypt and was previously known as “the official Let’s Encrypt client” or “the Let’s Encrypt Python client.” Certbot will also work with any other CAs that support the ACME protocol.

Generate a HTTPS certificate

Install

Installing the Cerbot on your machine.

sudo apt-get update
sudo apt-get install software-properties-common
sudo add-apt-repository universe
sudo add-apt-repository ppa:certbot/certbot
sudo apt-get update
sudo apt-get install python-certbot-nginx

Get Started

Running this command, Cerbot will generate a certificate for you, and also automatically edit your nginx configuration.

sudo certbot --nginx

After that, your .conf file will have these new lines:

server {
    listen      443;
    listen      [::]:443;
    server_name domain.com;
    ## Cerbot Certificate
    ssl_certificate /etc/letsencrypt/live/domain.com/fullchain.pem; # managed by Certbot
    ssl_certificate_key /etc/letsencrypt/live/domain.com/privkey.pem; # managed by Certbot
    include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot
    ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot

    location / {
        proxy_pass http://localhost:${app_port};
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection 'upgrade';
        proxy_set_header Host $host;
        proxy_cache_bypass $http_upgrade;
    }
}

Now you have your HTTPS certificate and your port 443 is enable on your nginx .conf.

Note

Check if your por 443 is enable on your firewall configuration.

sudo ufw status

Automating renewal

The Certbot packages on your system come with a cron job that will renew your certificates automatically before they expire. Since Let's Encrypt certificates last for 90 days, it's highly advisable to take advantage of this feature. You can test automatic renewal for your certificates by running this command:

sudo certbot renew --dry-run

More detailed information and options about renewal can be found in the full documentation.

Redirect HTTP to HTTPS

It's simple, just add this on you .conf file.

server {
    listen      80;
    listen      [::]:80;
    server_name www.domain.com domain.com.br;
    return 301 https://domain.com$request_uri; # managed by Certbot

}
