Change the working mode
Vim httpd-mpm.conf

Default is Prefork
When compiling, you can specify worker mode

Curl to view the site program version, so you need to hide the version number in default.conf
Curl-i 192.168.56.100

Virtual Hosting: Deploy multiple sites, each requiring a different domain name, site directory, or different port, and different IP. A virtual host is required for an HTTP service to configure multiple sites.

Make IP addresses inaccessible to Web sites
Set the first virtuahost and then give a rewrite
