Amazon ec2 Linux instances do not come with a GUI. By default, you need terminal access for all application configuration. Most of the developers\/sysadmins working with Linux would prefer the command line over Graphical User Interface. But developers who are new to Linux would require a GUI for installing and managing the applications. In this post, we will teach you how to configure a graphical user interface (GUI) for an Amazon ec2 Linux instance.<\/p>\n

Setting up GUI for Amazon ec2 Linux (RHEL)<\/h2>\n

Note: <\/strong>Please follow this tutorial for RHEL7. <\/strong>Configure GUI on RHEL 7<\/strong><\/a><\/p>\n

Follow the steps given below for setting up a desktop environment for ec2 RHEL6 instance.<\/p>\n

    \n
  1. Login to the instance using any ssh client like putty and update the server.<\/li>\n<\/ol>\n
    sudo yum update -y<\/code><\/pre>\n
      \n
    1. Install the Desktop environment.<\/li>\n<\/ol>\n
      sudo yum groupinstall -y \"Desktop\"<\/code><\/pre>\n
      [ec2-user@devopscube~]# sudo yum groupinstall -y \"Desktop\"\nxulrunner.x86_64 0:17.0.10-1.el6_4zenity.x86_64 0:2.28.0-1.el6\nComplete!<\/code><\/pre>\n
        \n
      1. Install few dependencies using the following command.<\/li>\n<\/ol>\n
        sudo yum install -y pixman pixman-devel libXfont<\/code><\/pre>\n
        [ec2-user@devopscube~]$ sudo yum install -y pixman pixman-devel libXfont\nInstalled:pixman-devel.x86_64 0:0.32.4-4.el6\nComplete!<\/code><\/pre>\n

          \n
        1. Install tiger VNC server.<\/li>\n<\/ol>\n
          sudo yum -y install tigervnc-server<\/code><\/pre>\n
          [ec2-user@devopscube~]$ sudo yum -y install tigervnc-server \nxorg-x11-fonts-Type1\nInstalled: \ntigervnc-server-module.x86_64 0:1.1.0-16.el6\nComplete!\n[ec2-user@devopscube~]$<\/code><\/pre>\n
            \n
          1. Set a password for the default user \u201cec2-user\u201d<\/li>\n<\/ol>\n
            sudo passwd ec2-user<\/code><\/pre>\n
            [ec2-user@devopscube~]$ sudo passwd ec2-user\nChanging password for user ec2-user.\nNew password:\nRetype new password:\npasswd: all authentication tokens updated successfully.\n[ec2-user@devopscube~]$<\/code><\/pre>\n
            6. Set a password for VNC server by executing the following command.<\/p>\n
            vncpasswd<\/code><\/pre>\n
            [ec2-user@devopscube~]$ vncpasswd\nPassword:\nVerify:\n[ec2-user@devopscube~]$<\/code><\/pre>\n
            7. Edit the sshd_config file and set the password authentication parameter to \u201cyes\u201d<\/p>\n
            8. Restart the sshd service.<\/p>\n
            sudo service sshd restart<\/code><\/pre>\n
            [ec2-user@devopscube~]$ sudo service sshd restart\nStopping sshd:                                             [ OK ]\nStarting sshd:                                             [ OK ]\n[ec2-user@devopscube~]$<\/code><\/pre>\n
            9.  Open the vncserver config file.<\/p>\n
            sudo vi \/etc\/sysconfig\/vncservers<\/code><\/pre>\n
            10. Update the parameters of vncserver config file as shown below.<\/p>\n
            VNCSERVERS=\"1:ec2-user 2:user2\"\nVNCSERVERARGS[1]=\"-geometry 1024x768\"\nVNCSERVERARGS[2]=\"-geometry 1024x768\"<\/code><\/pre>\n
            Note:<\/strong> You can add more than one user to access vnc server. In the above snippet, we have user2 apart from ec2-user and subsequently make entry for screen resolution for the particular user, as shown above.<\/em><\/p>\n
            11. Start the vnc server<\/p>\n
            sudo service vncserver start<\/code><\/pre>\n
            [ec2-user@devopscube~]$ sudo service vncserver \nstartStarting VNC server: 1:ec2-user \nxauth: creating new authority file \/home\/ec2-user\/.XauthorityNew 'ip-172-29-4-27:1 (ec2-user)'\n desktop is ip-172-29-4-27:1\nCreating default startup script \/home\/ec2-user\/.vnc\/xstartupStarting applications \nspecified in  \/home\/ec2-user\/.vnc\/xstartupLog \nfile is \/home\/ec2-user\/.vnc\/ip-172-29-4-27:1.log                                [ OK ]\n[ec2-user@devopscube~]$<\/code><\/pre>\n
            12. Add  vnc service to the system startup so that vnc server will automatically start after a system restart.<\/p>\n
            sudo chkconfig vncserver on<\/code><\/pre>\n
            13. VNC server uses ports starting from 5901. For the second user, the port will be 5902 and so on. In our case, we have only one user (ec2-user). So we will be connecting to the instance on port 5901. Add a firewall rule to your instance to open 5901 using the following command.<\/p>\n
            iptables -A INPUT -m state --state NEW -m tcp -p tcp --dport 5901 -j ACCEPT<\/code><\/pre>\n
            Note:<\/strong> Open TCP port 5901 in ec2 security group you have assigned to your instance.<\/em><\/p>\n
            14. Now we have an instance with GUI configured. To access it you need a VNC  client. Go to this link<\/a> to get a VNC viewer client. Install the software and open it.<\/p>\n
            15. Enter the public IP of you instance followed by the port number 5901 (assuming you the first vnc server user) and click connect. When asked for a password, supply the password you created for vnc server in step 6.<\/p>\n
            16. Now you will get the access to the GUI. If it asks for ec2-user password, supply the password you created in step 5.<\/p>\n
