Here article describes how to configure dual NICs on CentOS 7.
Ifconfig command again with a look on a Linux system, network information of the system. Here we have seen that the card has been identified, and access to the IP address via DHCP features of VMware virtual machines.
However, a second network card and the configuration file does not appear, here I need to write such a configuration file, here there is a very simple way.
Here you can directly copy a configuration file name to ens34 it will be able to directly use the cp command cp ifcfg-ens32 ifcfg-34.
Then vim ifcfg-ens34 command to enter the edit mode of the second block of the card.
Mainly to the following frame up a place to change the name on it, changed his name to ens34 it.
There is also a following that line UUID number directly using the dd command can be deleted, so CentOS7 double network card configuration is complete.
State after a change is complete.
Now try to second network card to configure a static IP address. BOOTPROTO into the back of the options static (static), and then coupled with IP addresses at the bottom, with the gateway subnet mask, and finally enter "w" to save and exit.
Finally restart the network services using systemctl restart network.service command.
Last seen just a static IP address has been successfully configured to go up.
