What are the steps for configuring domain name resolution in CentOS?

The steps for configuring domain name resolution on CentOS are as follows: 1. Open the terminal and log in to the server using the root user. 2. Edit the /etc/resolv.conf file, open it with a text editor, and add the following content:

  nameserver 8.8.8.8
  nameserver 8.8.4.4

The IP addresses 8.8.8.8 and 8.8.4.4 here are for Google Public DNS servers, but you can also use other DNS server addresses. Remember to save and close the /etc/resolv.conf file. Next, run the command “systemctl restart network” to restart the network service. Test if the domain name resolution is configured successfully by using the “ping” command to see if the domain can be resolved.

  ping example.com

Replace example.com with the domain name you want to test. Once you have completed the above steps, the domain resolution configuration for CentOS is complete.
