centos static IP config
From thelinuxwiki
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
