Apache configuration second-level domain name

We need to log in to the domain name management background of the operator of the purchased domain name and click on "Domain Resolution":

Manually add or one-click to quickly add the following two default resolutions, domain names like www.csdn.net and csdn.net can access the host address

Add a second-level domain name resolution that needs to be configured:

Then add the following domain name configuration at the end of the Apache configuration file httpd.conf:

<VirtualHost *:80>
  ServerAdmin [email protected]
  DocumentRoot /usr/local/apache/htdocs
  ServerName www.csdn.net
  ServerAlias www.csdn.net csdn.net
  DirectoryIndex index.php index.html index.htm
</VirtualHost>
<VirtualHost *:80>
  ServerAdmin [email protected]
  DocumentRoot /usr/local/apache/htdocs/blog
  ServerName blog.csdn.net
  ServerAlias blog.csdn.net
  DirectoryIndex index.php index.html index.htm
</VirtualHost>

Restart Apache, then the second-level domain name like blog.csdn.net can be accessed
