httpd.conf set an IP two domain name method

I just don't know how to get two domains to correspond to the same IP, and then identify different sites?

NameVirtualHost 12.34.56.78　# your ip address
<VirtualHost 12.34.56.78>
　　　　ServerName yourname1
　　　　DocumentRoot yourpath1
</VirtualHost>
<VirtualHost 12.34.56.78>
　　　　ServerName yourname2
　　　　DocumentRoot yourpath2
</VirtualHost>

If you are want to use 443

NameVirtualHost 12.34.56.78:80　# your ip address
NameVirtualHost 12.34.56.78:443　# your ip address

<VirtualHost 12.34.56.78:80>
　　　　ServerName yourname1
　　　　DocumentRoot yourpath1
</VirtualHost>
<VirtualHost 12.34.56.78:443>
　　　　ServerName yourname1
　　　　DocumentRoot yourpath1
</VirtualHost>
