CentOS-7 Reinstall

CentOS 2 Comments

I have a test system that I am using to investigate CentOS-7. I note the following difficulty when booting from the Minimal Install DVD.

Neither on the initial install nor on subsequent attempts at re-installing CentOS-7 can I set the IPv4 interface to a static IP address. I can configure it but I cannot save the changes. The save button remains greyed out.

  • If fisxed IP Addresses are to bo set up, I usually do it in
    /etc/sysconfig/network-scripts/ifcfg-interfacename. This file, on a CentOS 7 installation, looks like this:

    DEVICE=”eth0″
    ONBOOT=yes NETBOOT=yes NM_CONTROLLED=no UUID=”2c15111b-dd3d-4b31-9c5c-e01f13e36242″
    BOOTPROTO=static
    #BOOTPROTO=dhcp HWADDR=”90:1b:0e:11:f9:28″
    TYPE=Ethernet NAME=”eth0″
    #IPADDR2.168.97.67
    IPADDR!2.90.206.131
    #NETMASK%5.255.255.0
    NETMASK%5.255.255.224
    MTU50
    #GATEWAY2.168.97.2
    GATEWAY!2.90.206.129
    #
    IPV6INIT=yes
    # global scope IPV6ADDR=”2002:d45a:ce86::163/64″
    # site scope IPV6ADDR_SECONDARIES=”fec0::240:5ff:fe51:d92d/64″

    if you do changes in this file, you have to

    ifdown interfacename ifup interfacename

    in order to activate them.

  • Once the system is up and running then one has several options. What I wanted to do, and what the installer apparently will not permit, is to set a static address during the install. The GUI installer seemingly will not allow this. I wish to know if this is by design, a bug, or I am just not doing something right.
