1. Enter the directory: [root @ LinuxSir root] # CD / etc / sysconfig / network-scripts / 2: IFCFG-EH0: 0 EH0: 0 is the code of the NIC, of course, you can also use EH0: 1 How do you like it, but you must have IFCFG before EH0: X, which is the following form, we take EH0: 0 as an example. [root @ Linuxsir root] #CP ifcfg-eth0 IFCFG-ETH0: 03, Edit IFCFG-Eth0: 0 [root @ Linuxsir root] # vi ifcfg-eth0: 0iFCFG-ETH0: 0 There is such content, you can set this , Then IP can be set yourself. Like I set up like this. # Please read /usr/share/doc/initscripts-*/sysconfig.txt# for the documentation of these parameters.userctl = 'no'netmask =' 255.255.255.0 '- "Submasking bootproto =' static '-" protocol Device = 'eth0: 0' - "Ipaddr = '192.168.0.9' -" I set it myself iptype = 'ethernet'onboot =' yes' - "Don't activate NetWork = '192.168.0.0' - "Domain Broadcast = '192.168.0.255' -" Broadcast 4. Save Exit, then run the following command to activate the virtual network card. [root @ Linuxsir root] # iFUP EH0: 05. Let's see our virtual network card is activated, using ifconfig, that is, the following.
