Building a Virtual Host in CentOS 7 (Lab)
The proposed Web host runs multiple Web sites on the same physical server Each of these sites does not independently occupy a real computer httpd-supported virtual host type, domain name-based virtual host, IP address-based virtual host, port-based virtual host construction experiment, domain name-based virtual host [root@localhost] # yum install bind httpd-y / / install DNS and HTTP services [root@localhost] # cd / etc/ on the server / / enter the etc directory [root@localhost etc] # vim named.conf / / enter the edit DNS service main configuration file. / / omit some of the contents.

Open a win10 client, change the DNS server address, open a web page, and test the success of building a virtual host based on different domain names
Build virtual host based on port
In this experiment, we will directly change the configuration in the above experiment without reoperating it.

Verify the port-based virtual host configuration on the win10 client
Establishment of virtual host based on IP address
Here, add a network card to the Linux server virtual machine to obtain another IP address
Get the IP address in the virtual machine
