1. first, vmware needs to set it to the bridging mode so that the virtual machines are regarded as a computer with the host in a LAN, and then in centos, it can be set like the host in a LAN, for example, the host Ip address is 192.168.1.8, the gateway is 192.168.1.1, then centos is set as follows: vim/etc/sysconfig/network-scripts/ifcfg-eth0DEVIC
