How to Configure Apache Web Server to Use an SSL Certificate

Apache is a popular web server that can be configured to use an SSL (Secure Socket Layer) certificate to encrypt and secure data transmission between the server and client. In this blog post, we will walk through the steps of configuring Apache to use an SSL certificate.

Step 1: Obtain an SSL certificate Before you can configure Apache to use an SSL certificate, you must first obtain one. There are many companies that provide SSL certificates, such as DigiCert and Comodo. You can also generate a self-signed certificate for testing purposes.

Step 2: Install the SSL certificate Once you have obtained your SSL certificate, you will need to install it on your server. The exact steps for this will vary depending on your operating system and the type of certificate you have.

Step 3: Configure Apache to use the SSL certificate After the SSL certificate has been installed, you will need to configure Apache to use it. This involves editing the Apache configuration file, typically located at /etc/httpd/conf/httpd.conf or /etc/httpd/conf.d/ssl.conf.

You will need to add the following lines to the configuration file:

Listen 443

<VirtualHost _default_:443>
    DocumentRoot /var/www/html
    SSLEngine on
    SSLCertificateFile /path/to/your-domain.crt
    SSLCertificateKeyFile /path/to/your-domain.key
    SSLCACertificateFile /path/to/CA-bundle.crt
    <Directory /var/www/html>
        AllowOverride All

Be sure to replace “” with your actual domain name, and update the paths to the certificate and key files to match the location where you installed them.

Step 4: Restart Apache After making the changes to the configuration file, save the file and restart Apache to apply the changes.

On Ubuntu:

sudo service apache2 restart

On CentOS:

sudo service httpd restart

Congratulations! Your Apache web server is now configured to use an SSL certificate and your data transmissions will be encrypted.

Note: It’s important to note that SSL certificate alone is not enough to secure your website, you should also use harden your server security and keep up-to-date with the latest security patches and updates.
