Turn off firewall , start-up named service

Add... In the domain name resolution configuration file of the client DNS Server address

vim /etc/resolv.conf Entering and writing is effective immediately , No need to restart the network card , use echo I need to restart the network card

Configuration complete , Finally, test it
