Linux beginners in virtual machines configure IP and restart the network

For those who are new to virtual machines or have just installed Linux in a virtual machine, you need to configure the IP address yourself because the system is installed in the virtual machine.

Let's configure this IP address in several steps:

Step 1: Open your virtual machine, open Linux, and log in using the root account.

As shown in the figure, I am using the CentOS7.2 system. After clicking to log in, enter the command interface and enter vi /etc/sysconfig/network-scripts/ifcfg-eth0 (the latter eth is different for each computer, you can press the tab key to complete it.)

Follow the above instructions to enter the IP configuration interface, as shown in the figure

Since I have already configured it, there will be three more fields than yours (IPADDR, GATEWAY, NETMASK).

Press the i key to enter insert mode and set BOOTTPROTO to static
Set ONBOOT to yes

Add IPADDR (static IP) instance 192.168.2.200 GATEWAY (gateway) 192.168.2.1 NETMASK (subnet mask) 255.255.255.0

After completion, press shift+q, enter: wq, save and exit.

Then return to your virtual machine operation interface, click Edit in the virtual machine, select Virtual Network Editor, add a network and select Host-only mode. Then change the subnet IP of the network you just added to 192.168.2.0 (in my example), and the first three digits must be the same as your IP address.

As shown in the figure

After completing the above steps, click OK, then right-click your virtual machine, select Settings, and change your network adapter to the network you just created.

As shown in the figure

After exiting, enter service network restart to restart the network service

Then you can use Xshell or Xftp to connect to your server. If the connection is successful, it means that your IP address has been successfully configured and you can connect.
