A method for setting up a generic domain name resolution in the Apache virtual host _linux

1, support multiple domain names

For example, let mail.jbxue.org, smtp.jbxue.org, and pop3.jbxue.org all point to the same virtual host, which can be written as:

Copy Code code as follows:

ServerName mail.jbxue.org
Serveralias smtp.jbxue.org pop3.jbxue.org

ServerName is used to specify preferred domain names, and other domain names are specified with Serveralias and are separated by spaces.

2. Support for pan domain name resolution

Serveralias can support extensions, for example, we want all level two subdomains under xx.a.com to be resolved using the same virtual host, which can be set to:

Copy Code code as follows:

<virtualhost *:80>
ServerName xx.a.com
Serveralias *.xx.a.com
documentroot/var/www/htdocs/
</VirtualHost>
