When the installed operating system Ping www.google.com, report name or service not known
It’s OK to check the virtual network settings. Some virtual machines from the same template can or can’t Ping the Internet
Finally, several data are integrated, and the solutions are as follows:
1 add DNS server first
vi /etc/resolv.conf
Add the following two lines to the file:
nameserver 8.8.8.8
nameserver 8.8.4.4
Save, exit and restart the server. Then Ping again and try again
If not, continue:
2 set a file:
VI/etc/sysconfig/network scprits/ifcfg-ens33 (the file name may be different. Mine is ens33, and some seem to be ENS plus other numbers)
Find onboot = no in the file and change to onboot = yes
Save exit
Restart network: systemctl restart network
