We know that under Linux network card is called eth0, eth1, eth2 ....., all the network card configuration files are stored in / etc / sysconfig / network-script / under the file name is ifcfg-eth0, ifcfg-eth1 , ifcfg-eth2 .... to named. A card corresponding to a configuration file. If we give eth0 to configure two IP addresses, how are we to do?

1. Implementation of the "cp ifcfg-eth0 ifcfg-eth0: 1" to copy eth0 configuration file, the file name in the original file name added ": 1."

2. Editorial changes ifcfg-eth0: 1 in the appropriate fields, as follows:
