Solve the problem that vmware installs centos and the network is blocked

Enter in the terminal: nmcli dev status to view the status of the network card
I show here: eno16777736 The status is disconnected

Open the network card configuration options: sudo vim /etc/sysconfig/network-scripts/ifcfg-eno16777736
Modify one of the configurations, save and exit: ONBOOT= yes
restart the network service: sudo service network restart

After entering the above, the network configuration is ok
