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
