Not able to see GUI using Gnome in RHEL 7.2 deployed in Azure

Question

I am new to Linux environment. I have created a VM in Azure which has RHEL 7.2. I have installed Gnome 3.22.3 in it using Putty. I am NOT able to see the GUI for it. Is it possible to do it? I searched quite a bit, but, didn't find anything concrete. I followed these commands.

1) yum group list

2) a) yum groupinstall 'Server with GUI' (After downloading) Is this ok [y/d/N]: y

3) yum groupinstall 'X Window System' 'GNOME'

4) systemctl set-default graphical.target

5) gnome-shell --version

6) Reboot.

Still not able to see the GUI.

We can install xrdp on your VM, and add port 3389 to NSG inbound rules, then we can use mstsc to RDP it.

sudo -s
rpm -Uvh http://li.nux.ro/download/nux/dextop/el7/x86_64/nux-dextop-release-0-1.el7.nux.noarch.rpm
yum groupinstall "GNOME Desktop" "Graphical Administration Tools"
ln -sf /lib/systemd/system/runlevel5.target /etc/systemd/system/default.target
yum -y install xrdp tigervnc-server
systemctl start xrdp.service
netstat -antup | grep xrdp
systemctl enable xrdp.service
firewall-cmd --permanent --zone=public --add-port=3389/tcp
firewall-cmd --reload

Here a blog about how to enable GUI for centos 7 in classic module, please refer to this link.

Update:

Please follow this steps to install xrdp on your RHEL 7.2:

1.Install Gnome on RHEL 7.2 first:

yum group install "GNOME Desktop" "Graphical Administration Tools"
yum groupinstall "Server with GUI"
ln -sf /lib/systemd/system/runlevel5.target /etc/systemd/system/default.target
reboot

2.Install and configure EPEL repository:

rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm

3.Add nux repository:

rpm -Uvh http://li.nux.ro/download/nux/dextop/el7/x86_64/nux-dextop-release-0-1.el7.nux.noarch.rpm

Or Manual: vi /etc/yum.repos.d/xrdp.repo

[xrdp]
name=xrdp
baseurl=http://li.nux.ro/download/nux/dextop/el7/x86_64/
enabled=1
gpgcheck=0

4.Install xrdp:

yum -y install xrdp tigervnc-server
systemctl start xrdp.service

Check it with this command:

netstat -antup | grep xrdp

tcp        0      0 127.0.0.1:3350          0.0.0.0:*               LISTEN      1784/xrdp-sesman    
tcp        0      0 0.0.0.0:3389            0.0.0.0:*               LISTEN      1785/xrdp 

Enable the service at system start up:

systemctl enable xrdp.service

Add port 3389:

firewall-cmd --permanent --zone=public --add-port=3389/tcp
firewall-cmd --reload

Configure SELinux:

chcon --type=bin_t /usr/sbin/xrdp
chcon --type=bin_t /usr/sbin/xrdp-sesman

By the way, we should add port 3389 to NSG inbound rules:

Here is my result:
