onboot=yes # whether to turn on the boot NIC (yes)

ipaddr=192.168.1.11 #IP Address

netmask=255.255.255.0 # Subnet Mask

gateway=192.168.1.8 # Gateway

dns1=202.96.128.143 #DNS

nm_controlled=yes      # real-time, no need to restart the NIC immediately after the modification takes effect.

bootproto= static        # Specify how to get IP address static (static) DHCP (dynamic) None (not specified)

[email protected] ~]#/etc/init.d/network restart # Restart the NIC
