8. Configure 301 redirection in vhosts.conf under Apache

In order to realize URL normalization, SEO usually shifts the domain name without WWW to the domain name with www. the configuration in vhosts.conf is as follows:

<VirtualHost *:80>
ServerName DocumentRoot /home/embeta
<VirtualHost *:80>
ServerName embeta.com
RedirectMatch permanent ^/(.*)    $1

In addition to the above two methods under Apache, there are other configuration methods and optional parameters. It is recommended to read the Apache documentation.
