Config CentOS Network

If you installed CentOS with CentOS Minimal Installation, by default CentOS minimal install does not come with pre-configured network, here's how to config CentOS network and make it work

1. Check network

   ip link show
   

2. Configure eth0

   # Edit the set up for the ethernet and config centos network
   vi /etc/sysconfig/network-scripts/ifcfg-eth0
   

   ONBOOT=no => ONBOOT=yes
   # Config for static ip instead of dhcp
   BOOTPROTO=dhcp => BOOTPROTO=static
   IPADDR=192.168.1.87
   NETMASK=255.255.255.0
   GATEWAY=192.168.1.1
   DNS1=8.8.8.8
   DNS2=8.8.4.4
   

3. Restart Network Interface

   # Start network
   service network start
   # Restart network
   service network restart
