First, the configuration document detailed
In Linux systems such as Rhel or CentOS, the main setup files related to the network are as follows:
/etc/host.conf Configure the Domain Name Service client's control file
/etc/hosts The completion of the host name mapping to the IP address function
/etc/resolv.conf domain Name Service client configuration file, The location that specifies the
parameters causes the program to display the status of all network interfaces. To check the state of a particular interface, append the name of the interface after ifconfig. For example:
