Amazon-web-services – How To Set Up GUI On Amazon EC2 Ubuntu server

amazon-ec2amazon-web-servicesubuntuvnc

I'm using an amazon Ubuntu EC2 instance which is only has a command line interface. I want to setup UI for that server to access using remote desktop tools. Is there any way to apply GUI to the EC2 instance?

Best Solution

This can be done. Following are the steps to setup the GUI

Create new user with password login

sudo useradd -m awsgui
sudo passwd awsgui
sudo usermod -aG admin awsgui

sudo vim /etc/ssh/sshd_config # edit line "PasswordAuthentication" to yes

sudo /etc/init.d/ssh restart

Setting up ui based ubuntu machine on AWS.

In security group open port 5901. Then ssh to the server instance. Run following commands to install ui and vnc server:

sudo apt-get update
sudo apt-get install ubuntu-desktop
sudo apt-get install vnc4server

Then run following commands and enter the login password for vnc connection:

su - awsgui

vncserver

vncserver -kill :1

vim /home/awsgui/.vnc/xstartup

Then hit the Insert key, scroll around the text file with the keyboard arrows, and delete the pound (#) sign from the beginning of the two lines under the line that says "Uncomment the following two lines for normal desktop." And on the second line add "sh" so the line reads 

exec sh /etc/X11/xinit/xinitrc.

When you're done, hit Ctrl + C on the keyboard, type :wq and hit Enter.

Then start vnc server again.

vncserver

You can download xtightvncviewer to view desktop(for Ubutnu) from here https://help.ubuntu.com/community/VNC/Clients

In the vnc client, give public DNS plus ":1" (e.g. www.example.com:1). Enter the vnc login password. Make sure to use a normal connection. Don't use the key files.

Mac VNC client can be downloaded from here: https://www.realvnc.com/en/connect/download/viewer/

Port opening on console

sudo iptables -A INPUT -p tcp --dport 5901 -j ACCEPT

If the grey window issue comes. Mostly because of ".vnc/xstartup" file on different user. So run the vnc server also on same user instead of "awsgui" user.
