Apache for Newbie: Set up Apache with SSL/TLS stapling

Setting up Apache with SSL/TLS stapling can seem like a daunting task for beginners, but with the right guidance, it can be a straightforward process. In this article, we will walk you through the steps to set up Apache with SSL/TLS stapling on your Hong Kong VPS Hosting server.

What is SSL/TLS stapling?

SSL/TLS stapling is a method of improving the performance and security of your website by reducing the number of round trips required for a client to validate a server's SSL certificate. It works by having the server include a timestamped, digitally signed copy of the certificate's status in the initial SSL handshake, eliminating the need for the client to contact the certificate authority (CA) to verify the certificate's validity.

Setting up Apache with SSL/TLS stapling

Before you begin, make sure you have a valid SSL certificate installed on your server. If you don't have one, you can obtain one from a trusted CA or use a free service like Let's Encrypt.

Step 1: Enable SSL module

First, you need to enable the SSL module in Apache. You can do this by running the following command:

a2enmod ssl

After enabling the SSL module, restart Apache to apply the changes:

service apache2 restart

Step 2: Configure SSL/TLS stapling

Next, you need to configure SSL/TLS stapling in your Apache configuration file. Open the file with your preferred text editor and add the following lines inside the block:

<VirtualHost *:443>
    ...
    SSLUseStapling on
    SSLStaplingCache shmcb:/tmp/stapling_cache(128000)
    ...
</VirtualHost>

Replace the ellipses (...) with your existing configuration. The SSLUseStapling on directive enables SSL/TLS stapling, and the SSLStaplingCache directive specifies the location and size of the cache used to store the stapled responses.

Step 3: Test your configuration

After making the changes, test your Apache configuration for any syntax errors:

apachectl configtest

If there are no errors, restart Apache to apply the changes:

service apache2 restart

Step 4: Verify SSL/TLS stapling

To verify that SSL/TLS stapling is working correctly, you can use the following command:

openssl s_client -connect yourdomain.com:443 -status

Replace yourdomain.com with your actual domain name. If SSL/TLS stapling is configured correctly, you should see a section in the output that includes the stapled response from the CA.

Conclusion

Setting up Apache with SSL/TLS stapling on your Hong Kong VPS Hosting server can greatly improve the performance and security of your website. By following the steps outlined in this article, you can easily configure Apache to use SSL/TLS stapling and provide a better experience for your users. Remember to always keep your SSL certificate up to date and regularly test your configuration to ensure everything is working as expected.
