Setup HTTPS
To enable SSL, you can use a reverse proxy. In this case, we will use Nginx as the reverse proxy.
Install Nginx
sudo apt-get install nginx
Create Certificate
To proceed with this documentation, it is assumed that you already have a certificate for your domain.
You have the option to use Cloudflare or generate a certificate using Let’s Encrypt or Certbot.
Add the certificate to the following paths: /etc/key.pem
and /etc/cert.pem
Setup Nginx
sudo nano /etc/nginx/sites-available/default
server {
listen 80;
listen [::]:80;
server_name example.com www.example.com;
return 301 https://$server_name$request_uri;
}
server {
listen 443 ssl http2;
listen [::]:443 ssl http2;
server_name example.com www.example.com;
ssl_certificate /etc/cert.pem;
ssl_certificate_key /etc/key.pem;
location / {
proxy_pass http://localhost:8080;
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;
}
}
Restart Nginx
sudo systemctl restart nginx
Test
Vist your domain and you should see your application running with SSL.
