centos static IP config

file structure / paths similar / same as redhat. manual says to run system-config-network... but that utility wasn't installed on my centos. so, this method of configuring the network interfaces is done by manually editing the config files. it is good to know where they are anyway right? also included in this example is the default gateway config.

example /etc/sysconfig/ifcfg-eth0 file

DEVICE=eth0 
BOOTPROTO=none 
ONBOOT=yes 
NETWORK=10.0.1.0 
NETMASK=255.255.255.0 
IPADDR=10.0.1.27 
USERCTL=no
GATEWAY=10.0.1.254

then...

/etc/init.d/network restart
