Set up static IP in Linux

1: Enter in Terminal: cd/etc/sysconfig/network-scripts/

2: See if there is this file: Ifcfg-eth0, if there are then input edits, vi ifcfg-eth0:

3: Start editing, fill in the IP address, subnet mask, gateway, DNS and so on. Where "These are the ones that must be."

Device=eth0

Bootproto=static

Onboot=yes

ipaddr=198.1.102.140

netmask=255.255.224.0

gateway=198.1.96.1

Where: eth0 corresponding file name: Ifcfg-eth0

If you need to configure more than one IP, you need multiple files, each with one IP, with the file name: ifcfg-eth0_x,

And the file is device=eth0:x, where X can start from 1. For example file: Ifcfg-eth0_1 correspondence device=eth0:1
Other netmask and gateway are the same except that ipaddr needs to change.

4: When finished editing, save exit (: Wq).
5: Restart the network service. Service network restart or/etc/init.d/network restart
6:ping the gateway, ping the extranet for testing. Can ping to indicate that the network is normal.
