SETUP_SSL

Step 1: Install Certbot
Run the following commands to install Certbot, the Let’s Encrypt client:

sudo apt update
sudo apt install certbot python3-certbot-nginx -y
Step 2: Obtain an SSL Certificate
For NGINX:

sudo certbot --nginx -d yourdomain.com -d www.yourdomain.com
For Apache:

sudo certbot --apache -d yourdomain.com -d www.yourdomain.com
If you're using a different web server or running a standalone server, you can use:

sudo certbot certonly --standalone -d yourdomain.com -d www.yourdomain.com
Make sure no web server is running on port 80 before running this.

Step 3: Verify SSL Auto-Renewal
Check the renewal process:

sudo certbot renew --dry-run
Certbot automatically sets up a cron job to renew certificates.

Step 4: Restart Web Server
For NGINX:

sudo systemctl restart nginx
For Apache:

sudo systemctl restart apache2
