I want to install a graphical user interface (GUI) in my Amazon Elastic Compute Cloud (Amazon EC2) instance running Amazon Linux 2. How do I do this?

Short description

If you have an EC2 instance running and you have root access to this EC2 instance, then you can install MongoDB with authentication on EC2 AMI Linux in eight easy steps. I will be using mongo version 3.4. I will try to set up MongoDb server on EC2. Importing the Public Key sudo apt-key adv -keyserver hkp://keyserver.ubuntu.com:80 -recv 7F0CEB10. Sudo apt-get install -y mongodb-org -allow-unauthenticated Start MongoDB and add it as a service to be started at boot time sudo systemctl daemon-reload sudo systemctl start mongod sudo systemctl enable mongod Configure MongoDB username and password.

To install a GUI on your EC2 Linux instance, do the following:

1. Install the MATE desktop environment. MATE is a lightweight GUI based on GNOME 2 available as an extra for Amazon Linux 2. The Amazon Linux 2 offering of Amazon WorkSpaces uses MATE. For more information about MATE, see the MATE desktop environment website.
2. Install a virtual network computing (VNC) service, such as TigerVNC. For more information about TigerVNC, see the tigervnc.org website.
3. Connect to the GUI using the VNC.
4. (Optional) Install a web browser, such as Firefox or Chromium. For more information on Firefox, see the mozilla.org website. For more information on Chromium, see the chromium.org website.

Note: These instructions apply only to Amazon Linux 2. Dev c++ 5.11 c++ version. To confirm the version that you're running, run the following command:

Resolution

Before you begin

1. Use SSH to connect to your Amazon EC2 instance as ec2-user.

The instance must be in a public subnet and accessible through a public IP address or an Elastic IP address. Or, you can establish a connection using AWS VPN or AWS Direct Connect that allows you to access your instance through a private IP. These instructions don't apply to environments using a bastion host. For security reasons, traffic to the VNC server is tunneled using SSH. It's a best practice to avoid opening VNC ports in your security groups.

Install the MATE desktop environment

2. Define MATE as your default desktop.

To define MATE for all users:

To define MATE for the current user only (ec2-user):

Install TigerVNC

1. Install TigerVNC packages:

2. Configure a VNC-specific password containing 6 to 8 characters for this user. When asked if you want to enter a view-only password, press 'n'.

3. Start the VNC Server on display number 1.

Enter the following command to start the VNC Server only once:

Note: Entering this command prevents the service from coming up after a reboot.

Enter the following commands to always start the VNC Server at boot time:

Create a new systemd unit.

Use the sed command to replace all occurrences of USER in the new unit with ec2-user.

Reload the systemd manager configuration.

Enable the service.

Start the service.

Connect to the GUI using the VNC

1. Install the TigerVNC software on your local computer, if it's not already installed. TigerVNC is available for Linux, Windows, and macOS. See the TigerVNC website to access the download.

2. On your local computer, use SSH to connect to your instance while creating a tunnel to forward all traffic on local port 5901/TCP (VNC) to the instance's VNC server:

Connect to your instance using SSH.

Use the -L parameter to enable port forwarding. Replace PEM_FILE with your private key, and INSTANCE_IP with your instance's public or private IP, as appropriate.

Open the connection.

3. Open the VNC Client on your local computer. When asked for the VNC server hostname, enter localhost:1 and then connect to it.

4. Enter the VNC password you set up in step 2 of the Install TigerVNC section. If an alert appears stating that the connection isn't secure, disregard it. Although VNC data is unencrypted by default, you're accessing the VNC server using an encrypted SSH tunnel.

Your MATE desktop environment appears.

(Optional) Install a web browser

AWS currently doesn't provide web browsers such as Mozilla Firefox or Google Chromium in Amazon Linux 2 repositories. To install one of these browsers, follow the steps below.

Note: AWS doesn't provide support for software installed from third-party sources.

To install Chromium (open-source version of Google Chrome), do the following:

1. Enable the EPEL repository. See the EPEL documentation on the Fedoraproject.org website for more information.

2. Install Chromium packages.

Chromium installs on MATE under Applications, Internet, Chromium Web Browser.

To install Mozilla Firefox (current user only), do the following:

1. Download the latest Firefox version for Linux 64-bit to your local computer. See the mozilla.org website to access the download.

2. After downloading Firefox, copy the file to your instance.

3. Extract the file contents. The command below indicates that the file is in the ec2-user's home directory. Change the path and the Firefox version as needed.

4. Using vim or your favorite editor, create a desktop icon. Create the file ~/Desktop/Firefox.desktop with the contents as shown in the following example.

5. Use the icon you created in step 4 on your desktop to launch Firefox.
