RHEL7:- How to change graphical to multi user runlevel on Centos 7

1. Get the current run level
[root@new-host-4 ~]# runlevel
N 5
[root@new-host-4 ~]#


2. Get the default run level
[root@new-host-4 ~]# systemctl get-default
graphical.target

3. List the targets

[root@new-host-4 ~]# systemctl list-units --type=target

LOAD   = Reflects whether the unit definition was properly loaded.
ACTIVE = The high-level unit activation state, i.e. generalization of SUB.
SUB    = The low-level unit activation state, values depend on unit type.

20 loaded units listed. Pass --all to see loaded but inactive units, too.
To show all installed unit files use 'systemctl list-unit-files'.

4. Set the runlevel you like
[root@new-host-4 ~]# systemctl set-default multi-user.target
Removed symlink /etc/systemd/system/default.target.
Created symlink from /etc/systemd/system/default.target to /usr/lib/systemd/system/multi-user.target.
[root@new-host-4 ~]#

5. Verify your runlevel

[root@new-host-4 ~]# systemctl get-default

multi-user.target
