Run Centos Linux in GUI

I am trying to Run Centos in GUI mode.
After doing some research, I found that I need to do some changes in Inittab file.
https://www.centos.org/docs/5/html/5.1/Installation_Guide/ch14s04s02.html

however my Inittab file looks like the one in the screenshot below. how can I change it to boot in Gui mode ?

I have centos release 7.0
Thanks
centos

Apparently even after I changed it , it did not boot to GUI.

I changed it to this and did not boot in Gui

do you have KDE/GNOME installed on your system ? if not then runlevel 5 won't work for you.

read the first line of that file...

"inittab is no longer used when using systemd"

systemctl set-default graphical.target changes the run level in RHEL/CentOS 7

the documentation you are referring to is for CentOS 5 which does apply there; it doesn't apply here to 7

this is a virtual machine on my laptop.
I have VMware workstation installed on my laptop, and have installed Centos 7.0, but I could not run it into GUI mode...
I am not sure what kind of DNS issue, this could be ??

The last screenshot you posted is showing that when you are trying to install GUI pkgs on your system. It is unable to connect with internet due to name resolution failure so...

1. Check /etc/resolve.conf and correct the dns config.. In case you don't have in-house dns then use 8.8.8.8 and 4.2.2.2 as global dns.

2. Install GUI pkgs

3. modify default runlevel config.

There is Resolv.conf file under etc directory, but it is empty.

try this (replace my-eth1 with the device name):

nmcli con mod my-eth1 ipv4.dns "8.8.8.8 8.8.4.4"

I am not sure if I have eth0.
I run ifconfig , I get command not found

well I typed your command above in resolv.conf, assuming I have etho. However I still cannot boot to GUI

nmcli is a command; the IP addresses are separated by a space "8.8.8.8 8.8.4.4"
haven't worked with RHEL 7 too heavily so not sure if manually editing that file will be overwritten on reboot
