1. View the network configuration

 

 

 

Remember the three items of subnet IP, subnet mask, and gateway IP in the NAT settings. The next configuration file is mainly these three items.

2. Edit the network configuration file in Linux

vi /etc/sysconfig/network-scripts/ifcfg-ens33 #Note that the name of the network configuration file may be different. When entering ifcfg, you can press the tab key twice to get a prompt. For example, my machine is ifcfg-ens33

The content is replaced as follows:

TYPE=”Ethernet” 
BOOTPROTO=”static” #Static connection 
NAME=”ens33” 
UUID=”1f093d71-07de-4ca5-a424-98e13b4e9532” 
DEVICE=”ens33” 
ONBOOT=”yes” #Network device boot 
IPADDR=”192.168 .0.101” #192.168.59.x, x is 3~255. 
NETMASK=”255.255.255.0” #Subnet mask 
GATEWAY=”192.168.66.2” #Gateway IP

DNS1= 8.8.8.8

DNS2=8.8.8.4

 

3. View the network configuration

 

4. Restart the network service

　　service network restart

5. Test effect

Ping 192.168.66.2 
ping 115.239.210.27 (A certain IP of Baidu, if you ping www.baidu.com directly, there will be a problem with domain name resolution. You can configure it after ensuring network connectivity)

6、DNS文件配置

vi /etc/resolv.conf 
nameserver 8.8.8.8
nameserver 8.8.4.4
