Install CentOS 6.8 mininal

You should do after intstall CentOS minimal on your system

1. Enable active interface eth0 on system booting

# vi /etc/sysconfig/network-scripts/ifcfg-eth0

ONBOOT=yes

2. Change hostname to you want

# vi /etc/sysconfig/network

  hostname=lux1.kgitbank.local

In my case, When I install CentOS without NIC that NIC don't start at onboot

so, I make a file /etc/sysconfig/network.
