In the world of web hosting, acquiring an SSL certificate is only half the battle. The real magic happens during the installation. A poorly installed certificate can lead to Not Secure warnings, broken images, and a significant drop in your SEO rankings.
At Host Sonu, we want your transition to HTTPS to be as smooth as silk. Whether you’ve just purchased a Standard DV, a Wildcard, or a high-assurance EV certificate, this guide will walk you through the process of installing your SSL effectively to ensure 100% encryption and maximum browser trust.
Why Effective Installation Matters
Installing an SSL isn’t just about making the padlock appear. An effective installation ensures:
- Protocol Security: You aren’t using outdated versions of TLS.
- Asset Integrity: Every image, script, and CSS file loads over a secure connection.
- User Retention: Visitors don’t see “Mixed Content” warnings that scare them away.
Phase 1: Preparation and the CSR
Before you can install a certificate, you must “request” it from the Certificate Authority (CA). This is done through a Certificate Signing Request (CSR).
1. Generate the CSR
If you are using Host Sonu’s cPanel, navigate to the Security section and click SSL/TLS.
Select Generate a new CSR.
Enter your details. Important: The “Common Name” must be your exact domain (e.g., yourdomain.com). If you are installing a Wildcard SSL, use *. yourdomain.com.
Once generated, you will see a block of encoded text. Copy this.
2. Complete Validation
Submit this CSR to your SSL provider. The CA will then verify your domain ownership via email, DNS, or HTTP file upload. Once they are satisfied, they will email you your certificate files (usually a .crt file and a CA-Bundle file).
Phase 2: The Installation Process
Once you have your files from the CA, it’s time to put them to work. We will focus on the two most common environments: cPanel web hosting and Managed VPS hosting.
Method A: Installing via Host Sonu cPanel (Recommended)
This is the most user-friendly method and takes less than five minutes.
Log in to cPanel and click SSL/TLS under the Security tab.
Click Manage SSL Sites.
- Select Your Domain: Pick the domain you want to secure from the dropdown menu.
- Paste the Certificate: Open your .crt file in a text editor (like Notepad), copy the contents, and paste them into the Certificate: (CRT) box.
- Paste the Private Key: If you generated your CSR in cPanel, the private key might already be filled in. If not, paste it into the Private Key (KEY) box.
- The CA Bundle: Copy the contents of the intermediate certificate (CA-Bundle) provided by the CA into the Certificate Authority Bundle (CABUNDLE) box. This is vital for mobile browser compatibility!
- Click Install Certificate.
Method B: Manual Installation (Apache/Nginx)
If you are running a custom VPS, you will need to edit your configuration files.
For Apache: You will need to update your virtualhost file to point to your certificate paths:
Apache
SSLEngine on
SSLCertificateFile /path/to/your_domain.crt
SSLCertificateKeyFile /path/to/your_private.key
SSLCertificateChainFile /path/to/CA_bundle.crt
For Nginx: You usually need to concatenate your certificate and the CA-Bundle into one file before referencing it in your server block:
Nginx
ssl_certificate /etc/nginx/ssl/combined_cert.crt;
ssl_certificate_key /etc/nginx/ssl/your_private.key;
Phase 3: Post-Installation Checklist – Don’t Skip This!
Clicking Install is not the end of the journey. To make your SSL truly effective, you must perform these four critical steps.
1. Force HTTPS Redirection
Now that your site can use HTTPS, you need to make sure it must use HTTPS. You can do this by adding a few lines to your .htaccess file:
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond %{SERVER_PORT} !^443$
RewriteRule ^(.*)$ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
</IfModule>
This tells Google and your visitors that the secure version of your site is the only version that matters.
2. Fix Mixed Content Errors
This is the most common issue after installation. If your site is loaded via https://, but your images or scripts are still hardcoded to load via http://, the browser will show a Partial Security warning.
3. Update Search Console and Analytics
Google treats http://yourdomain.com and https://yourdomain.com as two different websites.
Go to Google Search Console and add your new HTTPS property.
Update your Google Analytics property settings to reflect the HTTPS prefix. This ensures your traffic data remains accurate.
4. Verify with an SSL Checker
Use an external tool like the Qualys SSL Labs Report. This will give your installation a “grade” (ideally an A or A+). It checks for:
- Expired certificates.
- Incomplete certificate chains (missing CA Bundles).
- Vulnerability to old exploits (like Heartbleed or POODLE).
SSL Installation Troubleshooting
| Issue | Likely Cause | Solution |
| “Connection Not Private” | Common Name Mismatch | Ensure the CSR was generated for the correct domain. |
| Broken Padlock Icon | Mixed Content | Update image/script links to use https://. |
| Works on Desktop, Fails on Mobile | Missing CA Bundle | Re-install and include the Intermediate/CA-Bundle file. |
| Redirect Loop | Conflicting .htaccess rules | Check your redirect logic to ensure it doesn’t loop back to HTTP. |
