Apache multiple domain hosting config

#This line is very important. It tells the server that this part is based on the name of the server, not IP address or anything else.
NameVirtualHost *:80 

# * means any ip address is fine. If you want to put, put your current server ip address. It's quite unlikely the server has multiple ip addresses. For normal people, * is good enough
<VirtualHost *:80>
#ServerName is used internally for Apache, so it does not matter what name you give it. As long as it does not conflict with other servers.
ServerName www.domain.tld
#This is the part specifies which domain it is serving. To be safe, always include the one without www and the one with www.
ServerAlias domain.tld www.domain.tld
#The files to be served for this domain.
DocumentRoot /www/domain
</VirtualHost>
