Apache How does a site bind multiple domain names?

We must have encountered such a situation, the need to APACHE2 a site binding multiple domain names, then how to operate it? With Serveralias

Used to be stupid, to make multiple domains point to the same site always write:

ServerAdmin [email protected]
Documentroot/www/domain.com
ServerName domain.com

ServerAdmin [email protected]
Documentroot/www/domain.com
ServerName www.domain.com

ServerAdmin [email protected]
Documentroot/www/domain.com
ServerName abc.domain.com

This is equal to how many domain names are tied and how many virtual hosts are open ...

Later read a book, found that there is a call "Serveralias" things can be used, in fact, can be:

ServerAdmin [email protected]
Documentroot/www/domain.com
ServerName domain.com
Serveralias www.domain.com abc.domain.com #绑定多个域名

How many domain names to tie can be written behind Serveralias, separated by a space
