Boot CentOS in CLI (Change runlevel)

After in installed CentOs VM in vmWare using easyInstall, it booted in GNOME GUI, which I do not really like, so i needed to change CentOs to boot in CLI.

for that we need to edit /etc/inittab

vi /etc/inittab


# inittab is only used by upstart for the default runlevel.
#
# ADDING OTHER CONFIGURATION HERE WILL HAVE NO EFFECT ON YOUR SYSTEM.
#
# System initialization is started by /etc/init/rcS.conf
#
# Individual runlevels are started by /etc/init/rc.conf
#
# Ctrl-Alt-Delete is handled by /etc/init/control-alt-delete.conf
#
# Terminal gettys are handled by /etc/init/tty.conf and /etc/init/serial.conf,
# with configuration in /etc/sysconfig/init.
#
# For information on how to write upstart event handlers, or how
# upstart works, see init(5), init(8), and initctl(8).
#
# Default runlevel. The runlevels used are:
# 0 - halt (Do NOT set initdefault to this)
# 1 - Single user mode
# 2 - Multiuser, without NFS (The same as 3, if you do not have networking)
# 3 - Full multiuser mode
# 4 - unused
# 5 - X11
# 6 - reboot (Do NOT set initdefault to this)
#
id:5:initdefault:

Change the last line

FROM
id:5:initdefault:

To
id:3:initdefault:</pre>
<pre>

if you reboot the centos now it will start with the splash screen and loading Graphical Bar, and I do not like that even. so to stop the graphical splash screen and loading bar, do the following step

edit the file /boot/grub/grub.conf

and find the line like following

vi /boot/grub/grub.conf


kernel /boot/vmlinuz-2.6.32-358.el6.x86_64 ro root=UUID=e5d67271-11e6-4abb-98d0-55188af5674c rd_NO_LUKS rd_NO_LVM LANG=en_US.UTF-8 rd_NO_MD SYSFONT=latarcyrheb-sun16 crashkernel=auto  KEYBOARDTYPE=pc KEYTABLE=us rd_NO_DM rhgb quiet

edit carefully this line and remove the last 2 words

rhgb quiet

save the file and reboot the box. you are done.

now CentOS box should be booting in complete CLI.
