This article mainly introduces the Linux system how to configure IP address, the article is very detailed, has a certain reference value, interested friends must read it!

(1) the Ifconfig command is the first to use the ifconfig command to configure the ip address of the network card. This command is usually used for 00:00 testing, after the computer starts

The configuration of the ip address will automatically fail. The specific usage is as follows. Ipconfig ethx ipadd netmask x.x.x.x .

The x in ethx represents the fast Ethernet card, and the default first block is 0.ipadd, which represents the ip address. X.x.x..x is the subnet mask. For example, the ip address configured for the network card eth0 is 192.168.1.1 with a subnet mask of 255.255.255.0. As shown in the following figure

Note (the ip address configured by this method will fail after the computer restarts) (2) neat command Neat command = configure ip address under redhat-config-network graph

Double-click the part under the picture that draws a red line

Ok exits after relevant configuration.
