Summary of the methods of setting static IP by CentOS

1. Modify the configuration of network card

DEVICE=eth0 # describes the device alias corresponding to the network card. For example, in the ifcfg-eth0 file, it sets the way for the network card to obtain the ip address for eth0BOOTPROTO=static #. The possible options are static,dhcp or bootp, corresponding to the statically specified ip address, respectively, and the ip address obtained through the dhcp protocol. The ip address obtained through the bootp protocol BROADCAST=192.168.0.255 # corresponds to the subnet broadcast address HWADDR=00:07:E9:05:E8:B4 # the physical address of the network card IPADDR=12.168.0.33 # if the network card is set to obtain the ip address, it is statically specified This field specifies the ip address of the network card, the network address of the NETMASK=255.255.255.0 # network card, the network mask of the NETWORK=192.168.0.0 # network card, and the network address of the network card.

NETWORKING=yes # (indicates whether the system uses a network, which is generally set to yes.
