How to Configure /Etc/Hosts In Vagrant Guest?

3 minutes read

To configure the /etc/hosts file in a Vagrant guest, you can SSH into the guest machine and edit the file using a text editor such as nano or vi. You can add entries that map IP addresses to hostnames to this file. These entries can help you easily access different services or websites by typing their hostnames instead of their IP addresses. Make sure to save the changes after editing the file. You may need to restart the networking service on the guest machine for the changes to take effect. Additionally, you can automate this process by using provisioning scripts in your Vagrantfile to automatically update the /etc/hosts file when the guest machine is created or provisioned.

What is the format of /etc/hosts file in vagrant guest?

The format of the /etc/hosts file in a Vagrant guest typically follows the standard host file format:

  • Each line in the file represents a mapping of an IP address to a hostname or domain name.
  • The IP address is followed by one or more hostname/domain name aliases separated by spaces or tabs.
  • Comments can be included in the file by starting the line with a "#" symbol.

For example:

2 localhost myapp.local

In this example, the IP address is mapped to the hostname "localhost", and the IP address is mapped to the hostname "myapp.local".

What is the significance of loopback address in /etc/hosts in vagrant guest?

The loopback address ( in /etc/hosts file of a vagrant guest is significant because it allows the guest machine to refer to itself using a specific hostname. This is particularly important for applications and services running on the guest machine that may need to communicate with each other using hostnames rather than IP addresses.

By adding the loopback address and corresponding hostname to the /etc/hosts file, the guest machine can resolve the hostname to its own IP address without needing to rely on external DNS servers. This can help improve performance and reliability of communication between different services on the guest machine.

Overall, the loopback address in /etc/hosts file of a vagrant guest helps streamline communication within the guest machine by providing a consistent and reliable way for services to refer to themselves using hostnames.

How to configure virtual hosts in /etc/hosts in vagrant guest?

  2. You may need to restart any services that rely on the hosts file to pick up the changes.

After completing these steps, you should have successfully configured a virtual host in the /etc/hosts file of your Vagrant guest.

What is the default content of /etc/hosts in vagrant guest?

The default content of /etc/hosts in a Vagrant guest machine typically includes the following lines: localhost <machine_name>

These lines map the localhost IP address to the hostname "localhost" and the hostname of the Vagrant guest machine to the loopback address.
