Linux under/etc/sysconfig/network-scripts/ifcfg-ethn file configuration

The configuration file for the system network device is saved under the "/etc/sysconfig/network-scripts" directory, Ifcfg-eth0 contains configuration information for the first network card, IFCFG-ETH1 configuration information that contains the second NIC.

The following is an example of a "/etc/sysconfig/network-scripts/ifcfg-eth0" file:

Device=eth0

Onboot=yes

Bootproto=static

ipaddr=192.168.0.66

netmask=255.255.255.0

gateway=192.168.0.65

If you want to manually modify the network address or add a new network interface to the new interface, you can do so by modifying the corresponding file (IFCFG-ETHN) or by creating a new file.
