centos 6.2

[syednasirraza]

im trying to install centos 6.2 on virtual box,,, the full installation was done sucesfully(as far as i know), it rebooted, but gives me only comand line to login, allows me to login from root user and then stays at that shell....is it not completely installed??why im not getting some desktop/gui???
im attaching the screen/shell i m geting to start with.... even after rebooting, it takes me back here....

It seems, you didnt choose a desktop environment during the install.
You probably have selected Minimal or one of the server types.

For a server, the console is the best choice. There is no need for a gui.
But if you want to use centos as a desktop, you can still install the desktop related packages.

yum groupinstall "Desktop" "Desktop Platform" "X Window System" "Fonts"

Hi,

syednasirraza . please check the runlevel in which you have booted after the installation.

you can check it by using below commands
runlevel

If your runlevel is not 5 then do the below changes.
a: init 5 - to switch over to runlevel

b: Permanent boot into runlevel 5
filename - /etc/inittab
set the runlevel - id:5:

If you have booted into runlevel 5, then you might not have installed gnome packages.
As suggested by Irithori installed desktop packages.

if you have installed desktop packages and your display server is not starting then use below commands :-
startx
- prefdm
to start you gui.

Keep status posted.

Best Wishes,
Warm Regards.

Hi,

"i checked runlevel, i was in runlevel 3"

Linux has 0-6 runlevels associated with it. As per your mentioned point.
You might have installed Centos for runlevel 3.

0 - shutdown
1 - single user mode
2 - Multiuser with no nfs
3 - multiuser text mode
4 - officially undefined
5 - multiuser graphical mode
6 - reboot

You have to check whether you have installed graphical desktop environment and install it.
yum groupinstall "Desktop" "Desktop Platform" "X Window System" "Fonts"

When the progress bar hangs just use any upward or downward arrow for which daemon it is taking time to load.

Host operating system has nothing to do with this issue.
Keep me posted.

Red Hat distros use run level 3 for command line mode by default, run level 5 for gui.
Debian distros use run level 2 for gui. I'm frankly not sure what run level 1 is in Debian, probably just command line mode.

So, you can't run in run level 5 yet because you haven't installed the Desktop software.

It looks like your VM can't access the internet/dns. If you configured your VM with a static IP, you need to make sure that:
1) You can ping the gateway (usually x.x.x.1, which is a virtual adapter of the host)
2) You have set up dns, which is also usually x.x.x.1. (to setup network config in command line mode, easiest way is to use system-config-network command).
3) You can ping public internet sites.

On the host (your ubuntu server) make sure IP tables is not blocking packets, and also make sure forwarding is enabled.
