How To Setup GUI For Amazon EC2 Linux Instance or Lightsail
Amazon ec2 Linux instances don't escort a user interface. By default, you wish terminal access for all application configuration. Most of the developers/sysadmins operating with Linux would like the program line over Graphical computer programme. however developers World Health Organization ar new Linux would need a user interface for putting in and managing the applications. during this post, we'll teach you the way to tack together a graphical computer programme (GUI) for Associate in Nursing Amazon ec2 Linux instance.
Setting Up GUI For Amazon Ec2 Linux (RHEL)
Follow the steps given below for setting up a desktop environment for ec2 RHEL6 instance.
1. Login to the instance using any ssh client like putty and update the server.
sudo yum install -y pixman pixman-devel libXfont
[ec2-user@devopscube~]$ sudo yum install -y pixman pixman-devel libXfont
Installed:pixman-devel.x86_64 0:0.32.4-4.el6
Complete!
4. Install tiger VNC server.
5. Set a password for the default user “ec2-user”
6. Set a password for VNC server by executing the following command.
7. Edit the sshd_config file and set the password authentication parameter to “yes”
8. Restart the sshd service.
9. Open the vncserver config file.
10. Update the parameters of vncserver config file as shown below.
11. Start the vnc server
12. Add vnc service to the system startup so that vnc server will automatically start after a system restart.
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.
14. Now we have an instance with GUI configured. To access it you need a VNC client. Go to this link to get a VNC viewer client. Install the software and open it.
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.
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.
Setting Up GUI For Amazon Ec2 Linux (RHEL)
Follow the steps given below for setting up a desktop environment for ec2 RHEL6 instance.
1. Login to the instance using any ssh client like putty and update the server.
sudo yum update -y2. Install the Desktop environment.
sudo yum groupinstall -y "Desktop"
[ec2-user@devopscube~]# sudo yum groupinstall -y "Desktop"
xulrunner.x86_64 0:17.0.10-1.el6_4zenity.x86_64 0:2.28.0-1.el6Complete!3. Install few dependencies using the following command.
sudo yum install -y pixman pixman-devel libXfont
[ec2-user@devopscube~]$ sudo yum install -y pixman pixman-devel libXfont
Installed:pixman-devel.x86_64 0:0.32.4-4.el6
Complete!
4. Install tiger VNC server.
sudo yum -y install tigervnc-server[ec2-user@devopscube~]$ sudo yum -y install tigervnc-server xorg-x11-fonts-Type1Installed: tigervnc-server-module.x86_64 0:1.1.0-16.el6Complete![ec2-user@devopscube~]$
5. Set a password for the default user “ec2-user”
sudo passwd ec2-user[ec2-user@devopscube~]$ sudo passwd ec2-userChanging password for user ec2-user.New password:Retype new password:passwd: all authentication tokens updated successfully.[ec2-user@devopscube~]$
6. Set a password for VNC server by executing the following command.
vncpasswd[ec2-user@devopscube~]$ vncpasswdPassword:Verify:[ec2-user@devopscube~]$
7. Edit the sshd_config file and set the password authentication parameter to “yes”
8. Restart the sshd service.
sudo service sshd restart[ec2-user@devopscube~]$ sudo service sshd restartStopping sshd: [ OK ]Starting sshd: [ OK ][ec2-user@devopscube~]$
9. Open the vncserver config file.
sudo vi /etc/sysconfig/vncservers
10. Update the parameters of vncserver config file as shown below.
VNCSERVERS="1:ec2-user 2:user2"VNCSERVERARGS[1]="-geometry 1024x768"VNCSERVERARGS[2]="-geometry 1024x768"Note: 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.
11. Start the vnc server
sudo service vncserver start[ec2-user@devopscube~]$ sudo service vncserver startStarting VNC server: 1:ec2-user xauth: creating new authority file /home/ec2-user/.XauthorityNew 'ip-172-29-4-27:1 (ec2-user)' desktop is ip-172-29-4-27:1Creating default startup script /home/ec2-user/.vnc/xstartupStarting applications specified in /home/ec2-user/.vnc/xstartupLog file is /home/ec2-user/.vnc/ip-172-29-4-27:1.log [ OK ][ec2-user@devopscube~]$
12. Add vnc service to the system startup so that vnc server will automatically start after a system restart.
sudo chkconfig vncserver on
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.
iptables -A INPUT -m state --state NEW -m tcp -p tcp --dport 5901 -j ACCEPTNote: Open TCP port 5901 in ec2 security group you have assigned to your instance.
14. Now we have an instance with GUI configured. To access it you need a VNC client. Go to this link to get a VNC viewer client. Install the software and open it.
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.
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.
