Configuring SSL/TLS on Apache Web Server with QuickServers

Secure Your Website with QuickServers’ SSL/TLS Configuration Guide

SSL/TLS encryption is essential for protecting your website’s visitors, securing sensitive data, and building user trust. If your website is hosted with QuickServers, configuring SSL/TLS on your Apache web server ensures every connection to your site is encrypted, authenticated, and SEO-friendly.

This step-by-step guide explains how to enable SSL/TLS on Apache, install your SSL certificate, and verify your website is fully secured.

1. Understanding SSL/TLS and Apache

Before getting started, it helps to understand what you’re configuring.

SSL (Secure Sockets Layer) and TLS (Transport Layer Security) are cryptographic protocols that encrypt communication between your web server and your visitors’ browsers.

Apache, one of the most widely used web servers, supports SSL/TLS through the mod_ssl module — allowing websites hosted on QuickServers to run securely using the HTTPS protocol.

When properly configured, SSL/TLS ensures:

  • Data exchanged between your site and users remains private

  • Visitors see a padlock icon in their browser

  • Your website ranks higher in search engines

2. Prerequisites

Before configuring SSL/TLS, make sure you have:

  • An active SSL certificate issued for your domain

  • The private key and certificate files (and, if applicable, the intermediate CA bundle)

  • Apache installed on your hosting environment

  • Root or administrative access to your server

If you purchased or activated your SSL certificate through QuickServers, you can easily download your certificate files from your hosting dashboard before proceeding.

3. Step-by-Step: Configuring SSL/TLS on Apache

Step 1: Enable mod_ssl on Apache

Apache requires the mod_ssl module to handle SSL connections. On most Linux distributions, you can enable it with:

sudo a2enmod ssl

Then restart Apache to apply the change:

sudo systemctl restart apache2

If you’re running CentOS, Fedora, or RHEL, mod_ssl may already be included. You can verify by checking your loaded modules:

httpd -M | grep ssl

Step 2: Upload Your SSL Certificate Files

You’ll typically have three key files to install:

  • Your domain certificate (your_domain.crt)

  • Your private key (your_domain.key)

  • Intermediate or CA bundle (ca_bundle.crt)

Upload these files to your Apache server, usually under:

/etc/ssl/certs/

and

/etc/ssl/private/

Ensure proper file permissions:

sudo chmod 600 /etc/ssl/private/your_domain.key

Step 3: Configure Your Apache Virtual Host

Locate your website’s SSL configuration file. Common paths include:

  • /etc/httpd/conf.d/ssl.conf (CentOS/RHEL)

  • /etc/apache2/sites-available/your_domain.conf (Ubuntu/Debian)

Add or edit the following configuration:

<VirtualHost *:443>
    ServerAdmin admin@yourdomain.com
    ServerName yourdomain.com
    ServerAlias www.yourdomain.com
    DocumentRoot /var/www/html

    SSLEngine on
    SSLCertificateFile /etc/ssl/certs/your_domain.crt
    SSLCertificateKeyFile /etc/ssl/private/your_domain.key
    SSLCertificateChainFile /etc/ssl/certs/ca_bundle.crt

    <Directory /var/www/html>
        Options Indexes FollowSymLinks
        AllowOverride All
        Require all granted
    </Directory>

    ErrorLog ${APACHE_LOG_DIR}/error.log
    CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>

Save and close the file.

Step 4: Redirect HTTP to HTTPS

To ensure all traffic is encrypted, redirect HTTP requests to HTTPS. In your non-SSL VirtualHost (port 80), add:

<VirtualHost *:80>
    ServerName yourdomain.com
    Redirect permanent / https://yourdomain.com/
</VirtualHost>

Alternatively, you can set a rewrite rule in your site’s .htaccess file:

RewriteEngine On
RewriteCond %{HTTPS} off
RewriteRule ^(.*)$ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]

Step 5: Test and Restart Apache

Check for syntax errors before restarting Apache:

sudo apachectl configtest

If you see:

Syntax OK

you’re ready to restart Apache:

sudo systemctl restart apache2

4. Verifying SSL Installation

Once Apache restarts successfully:

  • Visit your website at https://yourdomain.com

  • Look for the padlock icon in your browser

  • Use an SSL checker tool to confirm:

    • Certificate chain validity

    • Expiry date

    • Correct hostname and key pair

QuickServers tip: If your site doesn’t load properly after enabling HTTPS, check for mixed content warnings — replace all http:// resource URLs with https://.

5. SSL Maintenance and Renewal

SSL certificates have expiration dates and must be renewed regularly to maintain encryption.

When your certificate nears expiry, QuickServers will notify you in advance so you can renew it seamlessly. After renewal, simply replace the old certificate files with the new ones and restart Apache.

To further strengthen your configuration:

  • Use 2048-bit or higher key size

  • Disable older protocols like SSLv2 and SSLv3

  • Use TLS 1.2 or higher for modern encryption
