I. Virtual Host Concept Virtual Hosts allocate a certain amount of disk space on network servers for users to place sites and application components, and provide necessary site functions, data storage and transmission functions. The so-called virtual host, also known as "website space", is to divide a server running on the Internet into multiple "virtual" servers, each VM has an independent domain name and a complete Internet server (supporting WWW, FTP, e-mail, and so on). From the user's per

A virtual host can coexist with multiple sites. When the site has little traffic, multiple sites can run on one physical host to save resources (IP addresses and physical hosts. 1. IP-based VM: To implement a VM, you must first comment out the configuration of the central host, that is, disable the central host. You only need to comment out the line correspondin

… … … The above inet addr shows that the eth0 IP address is incorrect because Configure using DHCP is used when Redhat Linux is installed to Configure network parameters. The system defaults to IP addresses such as 10.0.0.10. Ifconfig can be used to set the IP address of the NIC:# Ifconfig eth0 192.168.0.2 sets its local
