Virtual Host Configuration

I. Port listening

Port: a number that allows a computer (with only one IP address) to provide multiple services (multiple functions)

Web Service 80

FTP 81

Receive email 110

Email sending 25

MySQL database 3306, but not absolutely !! A computer has about 60 thousand ports, but a server also provides services with over 10 ports.

Apache can be regarded as a waiter. The outside world initiates any request. However, some requests are not within the request range (beyond the port range). Pay attention to httpd. you can change the listen 80 in conf to the port number you need.

Host, that is, the Web site, allows the browser to access the address through the domain name, servername and DocumentRoot are two commonly used configuration items
