If not logged in as the root user, you may need to enter the root password to complete the command.
After running the above command, we need to flush the DNS cache. This command can vary widely depending on your specific distribution and version. At this point, your website should resolve on your local computer to the IP address specified in your hosts file instead of the IP address specified in the site's DNS record.
If you're not seeing the site on the new server, it could be because your browser is serving a cached version of the page. In this case, we can use the following steps to clear your cache.
