The minimal install of Centos 6.2 is exactly that. Very minimal while this is good for appliances if you dont know your way around linux and vi it could be a bit hard to get a network connection going.
Here are a few tips i have picked up.
Setup a IP address on a nic
ifconfig eth0 192.168.99.14 netmask 255.255.255.0 up
this will add a default gateway
route add default gw 192.168.99.254
These settings will be removed from the server on reboot.
Run this to make the nic come up on boot automatically.
# cd /etc/sysconfig/network-scripts/ # sed -i -e 's@^ONBOOT="no@ONBOOT="yes@' ifcfg-eth0
To put a dns server in try
echo “nameserver 18.104.22.168” > /etc/resolv.conf
This adds the google dns server to the resolv.conf file and your ready to go.
If you want to use a GUI to setup a perminate IP address try
yum install system-config-network-tui
