About this Hands-on Lab

In this hands-on lab, you will be provided with 2 Linux instances: 1 is CentOS, and 1 is Ubuntu.

You will be installing software on both of these servers and will be testing if the software was properly installed and works.

Learning Objectives

Successfully complete this lab by achieving the following learning objectives:

Log In to the Provided Servers, and Ensure They Are Ready

You have been provided with 2 servers: 1 CentOS and 1 Ubuntu. Log in to the servers as cloud_user with the provided passwords.

On Both Linux Servers, Install the Program Called ELinks

Using whatever command is required, your task is to install the program called ELinks on each of the provided Linux servers.

Since 1 server is CentOS and 1 server is Ubuntu, the commands required for this installation will be different on each.

Note: It may take a few minutes after the lab has started before the servers are ready. If you are unable to log in, please wait a couple of minutes and try again.

Create a Text File with Sample Data Inside, and Use the ELinks Program to Display It on Each of the Linux Servers

Using the appropriate command or an editor, add some sample text to the file called test.txt. This file should be created on both of the servers.

You can use the same text in each, or you can use different text. The task is to check that the ELinks program has been installed and is working by having it display the contents of the file.

The command to test that ELinks is working is: elinks test.txt.

Additional Resources

You have been tasked with installing and testing software on 2 Linux servers.

You have been provided with a CentOS 7 Linux instance and an Ubuntu 20.04 Linux instance.

Your task is to install the software called ELinks on both of the servers that have been supplied.

You will need to create a text file with some sample text inside. Once this is complete, you will use the ELinks software to test that you can read the contents of the text file.

Once this has been completed, verify the software is installed and working.
