Install centos7 after installing virtualbox. I won't repeat it here. There are many tutorials online.

First shut down the virtual machine and configure the network as follows

We need to use a dual network card here, and we are opening the second network card, as shown below

Then turn on the virtual machine and do the following

# go to the directory where the network card is located, cd / etc/sysconfig/network-scripts/#, back up the network card information cp-rp / etc/sysconfig/network-scripts/ifcfg-enp0s3 / etc/sysconfig/network-scripts/ifcfg-enp0s3.bak#, and edit vi / etc/sysconfig/network-scripts/ifcfg-enp0s3 The following TYPE= "Ethernet" PROXY_METHOD= "none" BROWSER_ONLY= "no" BOOTPROTO= "dhcp" DEFROUTE= "yes" IPV4_FAILURE_FATAL= "no" IPV6INIT= "yes" IPV6_AUTOCONF= "yes" IPV6_DEFROUTE= "yes" IPV6_FAILURE_FATAL= "no" IPV6_ADDR_GEN_MODE= "stable-privacy" NAME= "enp0s3" UUID= "ee340a0f-1557-49c7-a927-5069c4e2ab88" DEVICE= "enp0s3" ONBOOT= "yes"

The above configuration is the information of the network card 1 that we added, and we are copying a copy of the information modified to network card 2.

Cp-rp / etc/sysconfig/network-scripts/ifcfg-enp0s3 / etc/sysconfig/network-scripts/ifcfg-enp0s8TYPE= "Ethernet" PROXY_METHOD= "none" BROWSER_ONLY= "no" BOOTPROTO= "static" DEFROUTE= "yes" IPV4_FAILURE_FATAL= "no" IPV6INIT= "yes" IPV6_AUTOCONF= "yes" IPV6_DEFROUTE= "yes" IPV6_FAILURE_FATAL= "no" IPV6_ADDR_GEN_MODE= "stable-privacy" NAME= "enp0s8" UUID= "cb7e712d-c2db-4dee-8950-37f9d8a780e9" DEVICE= "enp0s8" ONBOOT= yes "IPADDR=" 172.21.208.200 "NETMASK=" 255.255.252.0 "GATEWAY=" 172.21.208.1 "DNS1=" 8.8.8 "

Note:

UUID should be replaced with your own. Using the uuidgen command, you can generate the IPADDR,NETMASK,GATEWAY in the attention enp0s8, not scribbling. Because our network card 2 chooses the bridging mode, that is to say, it is equivalent to connecting the virtual machine and the host to the same network environment, so you need to check the configuration of the host. Use WIN+R, type cmd+ enter, and open the dos command line. Enter ipconfig / all to view the network configuration in the host, as follows

Look carefully, the network segment configured in Nic 2 is the same as that on the host. You can use xshell to connect to the ip in Nic 2.
