Setting a Default Virtual Host in Apache on Debian 10

When managing a web server using Apache on Debian 10, it's common to deal with multiple virtual hosts (VH). If you have a main domain and a subdomain configured and notice that visiting your VPS's IP address redirects to the subdomain instead of your primary domain, you might be searching for a solution to set a default virtual host. This post will guide you through the steps to achieve that seamlessly.

Understanding the Problem

In our scenario, you have a VPS set up with two virtual hosts:

Main Domain: example.net

Subdomain: admin.example.net

The issue arises when you type the VPS's IP address into your browser, and it leads you to the subdomain (admin.example.net) instead of your main domain (example.net). The aim is to make example.net the default site that appears when accessing your server’s IP.

Solution Overview

To change the default virtual host in Apache, we need to ensure that the configuration for your main domain (example.net) is applied correctly as the default option. Here’s how you can do it:

Step-by-Step Guide to Setting the Default Virtual Host

Open the Default Configuration File
First, you need to access the default virtual host configuration file, typically named 000-default.conf. You can find this file in the directory:

Edit the Configuration File
You will add or modify the existing configuration to include the settings for your main domain. Use your preferred text editor to open the file:

Insert the Following Configuration
Below is the configuration you will need to include in the 000-default.conf file. This directs traffic to the main domain when accessing the VPS IP address:

Save and Exit
After adding or updating the configuration, save the file and exit the text editor. If you are using nano, you can do this by pressing CTRL + X, then Y to confirm changes, and Enter to save.

Restart Apache
The final step involves restarting the Apache service to apply the changes. Run the following command:

Test Your Configuration
After restarting, open your web browser and input your VPS's IP address. You should now see the main domain (example.net) load by default instead of the subdomain.

Conclusion

By following the steps detailed in this guide, you can easily set your desired default virtual host on Apache in Debian 10. This ensures that users visiting your VPS's IP will be directed to your main domain rather than a subdomain, improving access to your primary website. If you encounter further issues, checking the Apache error logs will often provide helpful insight into any configuration problems. Happy hosting!
