7. Then use the Linux command line to open the configuration file of the first network card /etc/sysconfig/network-scripts/ifcfg-ens33
command:

[root@localhost ~]# vim /etc/sysconfig/network-scripts/ifcfg-ens33

After opening, the vim text is modified as follows:

8. Restart the network card ens33, and test whether the network is connected under Linux. If the packet loss is equal to 0%, the network is connected.
command:

[root@localhost ~]# ifdown ens33
[root@localhost ~]# ifup ens33
