SSL requirements

  • A domain name
  • SSH access
  • sudo privileges

​
Installing dependencies

:::info This tutorial will use Ubuntu Jammy 22.04 LTS as the operating system, and Cloudflare as the DNS provider. ::: To install the dependencies, you will need to run the following commands: 
sudo apt update && sudo apt upgrade
sudo apt install nginx certbot python3-certbot-nginx

​
Adding a domain name

For this, we will want to go to Cloudflare, and create an A record for our domain with the name you want and your server’s Public IP. img1

​
Setting nginx virtual host

To enable this, we will need to edit the file /etc/nginx/sites-enabled/pufferpanel.conf, and we will use nano to edit it. To edit it, run the following command: 
sudo nano /etc/nginx/sites-enabled/pufferpanel.conf
And now, you have to add the following: Remember to change panel.examplehost.com to your domain name! 
server {
         listen 80;
         root /var/www/pufferpanel;

         server_name panel.examplehost.com;

         location ~ ^/\.well-known {
           root /var/www/html;
           allow all;
         }

         location / {
             proxy_pass http://localhost:8080;
             proxy_set_header X-Real-IP $remote_addr;
             proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
             proxy_set_header X-Nginx-Proxy true;
             proxy_http_version 1.1;
             proxy_set_header Upgrade $http_upgrade;
             proxy_set_header Connection "Upgrade";
             proxy_set_header Host $host;
             client_max_body_size 100M;
         }
     }
If you’re using PuTTY, you can right click on the terminal to paste it, and if you’re using just a terminal, you can press Ctrl + Shift + V to paste it. To save now, you have to press Ctrl + X, and then Y. Now you’ll want to restart nginx, to do that, run the following command: 
sudo systemctl restart nginx
We also need to open ports 80 and 443, so we can access the panel. 
sudo ufw allow 80
sudo ufw allow 443
sudo ufw reload

​
Enabling SSL

To enable SSL, we will need to run the following command: 
sudo certbot --nginx -d (yourdomain)
And that’s it! Now if you go into your browser, and try to go into https://(yourdomain), you should be able to access the panel!
