Missing option to select packages during install of Centos 6.7 x86

Following the steps at http://www.tecmint.com/centos-6-3-step-by-step-installation-guide-with-screenshots/ step 19 never happens and the installation proceeds to create only a terminal mode system. AT the “name your system” step I entered the full domain name of my PC and went to “configure network” where I put in the IPv4 info: use DHCP, use the existing MAC address. After the reboot, I tried to ping some systems by their IP addresses and got “network is unreachable”. I am not a networking expert. How can I troubleshoot this and/or fix it.

Decided to research after thinking some more. So I searched on activating the network. Found the command “ifup eth0”, which got it going.
I’m now doing the steps to install Gnome using the following:
yum groupinstall -y ‘X Window System’
yum groupinstall -y ‘Desktop’
edit /etc/inittab to change id:3 to id:5
yum groupinstall -y fonts
startx
reboot

I think you’ve selected minimal packages during installation, that’s the reason you’ve got command line mode. For Desktop Environment, you need to install X Window and change run level init 3 to init 5 under inittab file as suggested in the commands…

I was not given a choice for packages to be installed. Centos 6.7 X86 has only one installation download file. There is no choice of minimal or full. I believe my problem was that my network adapter was not activated and the installer could not check (or would not) for packages to install and did not offer to activate the adapter.

PS. the PC previously had Fedora on it and the adapter was working. I do not know why the adapter had to be re-activated, but the installer should do that.
PPS. I NEED Centos 6.7, because we are also running it on our Z390 mainframe Linux systems & I wanted a standalone system that matches that. I have no control over upgrading to Centos 7 on the mainframe.

Hi…

Can you provide this file (/etc/sysconfig/network-scripts/ifcfg-eth0) information?

@NITIN_SHRIVASTAV

DEVICE=eth0
TYPE=Ethernet
UUID=--------------------------------
ONBOOT=yes
NM_CONTROLLED=yes
BOOTPROTO=none
DNS2=-------------------
DNS1=------------------
IPV6INIT=no
USERCTL=no
PREFIX=26
DEFROUTE=yes
NAME=“System eth0”
IPADDR=------------
NETMASK=----------------
GATEWAY=---------------------
HWADDR=------------------

Here is the file after I issued the commands in my previous post:

DEVICE=eth0
TYPE=Ethernet
UUID=5cd7042b-90da-4652-9649-0360c45e666a
ONBOOT=no

First you need to check your Ethernet Card working or not,So try this are commands to check the Ethernet status.

  1. dmesg | grep eth0

Output :- e1000e 0000:00:19.0: eth0: (PCI Express:2.5GT/s:Width x1) 54:be:f7:37:cf:af
e1000e 0000:00:19.0: eth0: Intel® PRO/1000 Network Connection
e1000e 0000:00:19.0: eth0: MAC: 11, PHY: 12, PBA No: FFFFFF-0FF
ADDRCONF(NETDEV_UP): eth0: link is not ready
e1000e: eth0 NIC Link is Up 1000 Mbps Full Duplex, Flow Control: Rx/Tx
ADDRCONF(NETDEV_CHANGE): eth0: link becomes ready
eth0: no IPv6 routers present

  1. ethtool eth0 | grep Link

Output :- Link detected: yes

  1. #cat /sys/class/net/eth0/operstate
    Output :- up

After run this are commands your output similar this are output it means your ether card is ok.
Now you can configure network interface.
For example :- vi /etc/sysconfig/network-scripts/ifcfg-eth0

DEVICE=eth0
HWADDR=00:50:43:00:3B:AE
TYPE=Ethernet
UUID=c1539085-73d7-4455-ac82-88f26464458a

change

ONBOOT=yes

NM_CONTROLLED=yes

change

BOOTPROTO=none

add follows

this server’s IP address

IPADDR=10.0.0.30

subnet mask

NETMASK=255.255.255.0

default gateway

GATEWAY=10.0.0.1

DNS server’s IP address

DNS1=10.0.0.10
IPV6INIT=no
USERCTL=no

#/etc/rc.d/init.d/network restart
Shutting down interface eth0: [ OK ]

Shutting down loopback interface:[ OK ]

Bringing up loopback interface: [ OK ]

Bringing up interface eth0:[ OK ]
#chkconfig network on

ifconfig

Now ping you system ip address and gateway also.
