Free SSL Certification Creation and Integration 

How to Obtain and Integrate Free SSL Certificates with Nginx Using Let’s Encrypt

Securing your website with SSL (Secure Sockets Layer) certificates is crucial for protecting sensitive information and building trust with your users. Let’s Encrypt offers free SSL certificates, and integrating them with Nginx is straightforward. Follow these steps to secure your website with SSL:

Step 1: Install Let’s Encrypt Tools

First, ensure your system is up to date:

sudo apt-get update

Then, install the Let’s Encrypt Certbot tool:

sudo apt-get install certbot python3-certbot-nginx

Step 2: Configure Nginx

Navigate to the Nginx configuration directory:

cd /etc/nginx/con.d/

Create or edit your site’s configuration file:

sudo nano myweb.com.conf

Add the following Nginx configuration:

server { listen 80; listen [::]:80; server_name myweb.com www.myweb.com; root /var/www/myweb.com; # Additional Nginx configuration… }

Test the Nginx configuration:

sudo nginx -t

Step 3: Stop Nginx

Before generating the SSL certificate, stop Nginx:

sudo systemctl stop nginx

Step 4: Generate SSL Certificates

Generate the SSL certificate and key for your domain: 

Note: before run these command you must add this server IP into into the domain manager A Records across to the domain 

sudo certbot certonly –standalone -d myweb.com sudo certbot certonly –standalone -d www.myweb.com

Step 5: Update Nginx Configuration with SSL

Edit your Nginx configuration file to include SSL certificate paths:

server { listen 80; listen [::]:80; server_name myweb.com www.myweb.com; root /var/www/myweb.com; listen 443 ssl; # SSL configuration ssl_certificate /etc/letsencrypt/live/myweb.com/fullchain.pem; ssl_certificate_key /etc/letsencrypt/live/myweb.com/privkey.pem; include /etc/letsencrypt/options-ssl-nginx.conf; ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # Redirect non-https traffic to https if ($scheme != “https”) { return 301 https://$host$request_uri; } # Additional Nginx configuration… }

Step 6: Restart Nginx

Test the Nginx configuration and restart Nginx:

sudo nginx -t

If get ok message then start the nginx server 

sudo systemctl start nginx

Step 7: Automate Certificate Renewal

Set up a cron job to automatically renew the SSL certificate:

sudo crontab -e

Add the following cron job to run the renewal command daily:

0 12 * * * /usr/bin/certbot renew –pre-hook “service nginx stop” –post-hook “service nginx start” –quiet

With these steps, your website is now secured with free SSL certificates from Let’s Encrypt, ensuring encrypted communication between your server and your visitors’ browsers. Regular certificate renewal guarantees continuous protection for your website.
