<p>Let’s Encrypt is a free SSL provider. Porkbun is very good domain registrar. We can download free SSL from porkbun dashboard. All we need is to upload it into our VPS server and need to add the path of the certificates into virtual host file.</p>



<p>Download SSL from porkbun.</p>



<div class="wp-block-image"><figure class="aligncenter size-large"><img src="http://ec2-13-127-91-65.ap-south-1.compute.amazonaws.com/wp-content/uploads/2020/07/porkbun-1024x617.jpg" alt="" class="wp-image-702"/></figure></div>



<p>You shall get a ZIP file containing the following 4 files:-</p>



<ol><li>domain.cert.pem</li><li>intermediate.cert.pem</li><li>private.key.pem</li><li>public.key.pem</li></ol>



<p>Now Upload file no. 1 and 3 only (i.e. domain.cert.pem and private.key.pem) into your VPS home folder (i.e. /home/admin/).</p>



<p>Create a Virtual Host for your domain (for example: yourdomain.com) as shown below:</p>



<pre class="wp-block-code"><code>sudo nano /etc/nginx/sites-available/wbxpress.net.conf</code></pre>



<pre class="wp-block-code"><code>server {
    server_name    yourdomain.com www.yourdomain.com;
    root           /var/www/yourdomain;
    index          index.html index.php;

    location / {
        try_files $uri $uri/ /index.php?$args;
    }

    location ~* \.php$ {
        fastcgi_pass unix:/run/php/php7.2-fpm.sock;
        include         fastcgi_params;
        fastcgi_param   SCRIPT_FILENAME    $document_root$fastcgi_script_name;
        fastcgi_param   SCRIPT_NAME        $fastcgi_script_name;
    }

    listen 443 ssl http2;
    listen &#91;::]:443 ssl http2;

    ssl_certificate /home/admin/domain.cert.pem;
    ssl_certificate_key /home/admin/private.key.pem;	
}
server {
    if ($host = www.yourdomain.com) {
        return 301 https://yourdomain.net$request_uri;
    }
    if ($host = yourdomain.com) {
        return 301 https://yourdomain.net$request_uri;
    }
    listen 80;
    listen &#91;::]:80;
    server_name yourdomain.com www.yourdomain.com;
    return 404;
}</code></pre>



<p>Also, we need to replace SSL settings as found from <a href="https://mozilla.github.io/server-side-tls/ssl-config-generator/" target="_blank" rel="noreferrer noopener">SSL Config File Generator</a> at nginx.conf file.</p>



<pre class="wp-block-code"><code>sudo nano /etc/nginx/nginx.conf</code></pre>



<pre class="wp-block-preformatted">ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
ssl_ciphers 'ECDHE-ECDSA-CHACHA20-POLY1305:ECDHE-RSA-CHACHA20-POLY1305:ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-RSA-AES128-GCM-SHA256:ECDHE-ECDSA-AES256-GCM-SHA384:ECDHE-RSA-AES256-GCM-SHA384:DHE-RSA-AES128-GCM-SHA256:DHE-RSA-AES256-GCM-SHA384:ECDHE-ECDSA-AES128-SHA256:ECDHE-RSA-AES128-SHA256:ECDHE-ECDSA-AES128-SHA:ECDHE-RSA-AES256-SHA384:ECDHE-RSA-AES128-SHA:ECDHE-ECDSA-AES256-SHA384:ECDHE-ECDSA-AES256-SHA:ECDHE-RSA-AES256-SHA:DHE-RSA-AES128-SHA256:DHE-RSA-AES128-SHA:DHE-RSA-AES256-SHA256:DHE-RSA-AES256-SHA:ECDHE-ECDSA-DES-CBC3-SHA:ECDHE-RSA-DES-CBC3-SHA:EDH-RSA-DES-CBC3-SHA:AES128-GCM-SHA256:AES256-GCM-SHA384:AES128-SHA256:AES256-SHA256:AES128-SHA:AES256-SHA:DES-CBC3-SHA:!DSS';
ssl_prefer_server_ciphers on;</pre>



<p>The above configuration works perfectly well in our case.</p>

How to Install a Porkbun SSL on NGINX

<p>In this tutorial we are going to show you, with step-by-step instructions on how to install Let’s Encrypt with Apache on Ubuntu.</p>



<p>Let’s Encrypt is an open SSL Certificate Authority (CA) that offers free domain-validated (DV) certificates for your websites. SSL Certificates are used to establish a secure encrypted connection between a web server and a user’s web browser. The SSL certificates that have been issued by Let’s Encrypt are valid for 90 days and are trusted by most web browsers today.</p>



<h2>1. Requirements</h2>



<p>In order to start with the installation procedure, you need to have Apache or Nginx installed on your server. If there is no web server installed on your virtual server, please follow this tutorial to install Apache.</p>



<p>Also, you need a registered domain name with its A record pointing to your server’s IP address. For the purposes of this tutorial, we will use ‘yourdomain.com’.</p>



<h2>2. Install CertBot</h2>



<p>Run the following commands:</p>



<pre class="wp-block-code"><code>sudo apt-get install software-properties-common python-software-properties
sudo add-apt-repository ppa:certbot/certbot
sudo apt-get update
sudo apt-get install python-certbot-apache</code></pre>



<h2>3. Install Let’s Encrypt SSL</h2>



<p>Install Let’s Encrypt SSL certificate on your domain (do not forget to replace ‘yourdomain.com’ with your actual domain):</p>



<pre class="wp-block-code"><code>sudo certbot --apache -d yourdomain.com</code></pre>



<pre class="wp-block-preformatted">Saving debug log to /var/log/letsencrypt/letsencrypt.log

<h2>4. Redirect HTTP traffic to HTTPS</h2>



<pre class="wp-block-preformatted">Please choose whether or not to redirect HTTP traffic to HTTPS, removing HTTP access.
1: No redirect - Make no further changes to the webserver configuration.
2: Redirect - Make all requests redirect to secure HTTPS access. Choose this for
new sites, or if you're confident your site works on HTTPS. You can undo this
change by editing your web server's configuration.

Congratulations! You have successfully enabled https://yourdomain.com</pre>



<h2>5. Renew the SSL certificate with a cron job</h2>



<p>Create a cron job so the SSL certificate is renewed automatically. Run:</p>



<pre class="wp-block-code"><code>crontab -e</code></pre>



<p>and add the following line:</p>



<pre class="wp-block-code"><code>0 0 1 * * /usr/bin/letsencrypt renew >> /var/log/letsencrypt-renew.log</code></pre>



<p>Save and close that file and restart cron service for the changes to take effect:</p>



<pre class="wp-block-code"><code>service cron restart</code></pre>



<p>Open https://yourdomain.com in your favorite web browser, and check whether Let’s Encrypt SSL is installed properly:</p>

<p>That is it. Let’s Encrypt SSL certificate has been successfully installed on your website.</p>
