Add DNS server address in Linux

Add DNS server address in Linux

Ping www.baidu.com on linux fails, which indicates that the Domain Name Server is not properly configured.
Cat/etc/resolv. conf check the configured IP address. How can I know the IP address of the Domain Name Server?

I found that windows computers can be used for hundreds of times, indicating that there is a Domain Name Server.
Find the dns ip address on windows
Ping the Domain Name of the central system in cmd, And the IP address may be displayed. Enter the address in/etc/resolv. conf.

Vi/etc/resolv. conf Add a row
Nameserver 192.168.0.110

Solution.
In addition, wget yum cannot be downloaded and installed.
