Apache2 NameVirtualHost *:80 has no VirtualHosts Error and Solution

The “NameVirtualHost *:80 has no VirtualHosts” error is encountered when configuring Apache2 to serve multiple websites, also known as virtual hosts, on a single server. The error occurs when the virtual host configuration is incorrect and Apache2 is unable to find any matching virtual host for a request.

To resolve the error, you can try the following solutions:

1. Verify VirtualHost configuration: Ensure that the virtual host configuration is correct and that the virtual host block contains all necessary information such as the server name and document root.
2. Use the correct NameVirtualHost directive: Ensure that the NameVirtualHost directive is specified correctly in the Apache2 configuration file and that it matches the IP address and port specified in the virtual host blocks.
3. Check for duplicates: Check for duplicates of the NameVirtualHost directive and remove any duplicates.
4. Use a unique IP address for each virtual host: If you have multiple virtual hosts, you should assign a unique IP address to each virtual host. This ensures that each virtual host can be identified by its unique IP address and that requests are sent to the correct virtual host.
5. Disable virtual host mapping: If you don’t need virtual host mapping, you can disable it by commenting out or removing the NameVirtualHost directive.

Example virtual host configuration:

Note: The above configuration assumes that the virtual hosts are accessible on port 80 and that the server is configured to listen on all IP addresses (*). Make sure to adjust the configuration as necessary for your setup.
