Deploy a Tomcat Application Using the CLI
Welcome to this hands-on lab, where we'll deploy an application on Tomcat via the CLI. We are using Apache's Tomcat, a Java-based application platform built around deploying and managing Java Web Applications. The server provided in this lab environment is running Red Hat Enterprise 8 and has Tomcat 9 pre-installed for you. The Tomcat instance is available for you on port **8080**. You will log into the server via the CLI and deploy an application. You will then deploy a second version of the application. It has different information on its index page that shows the new application has been launched to replace the original. Both of the applications will be provided in a folder on the Tomcat server for your use.

Challenge
Test to Ensure You Can Access the Preconfigured Tomcat Instances on Port 8080
Connect to the Tomcat GUI and log in. To access the server, visit the external IP address provided in the hands-on lab page, and append :8080 to it.
For example, if an IP address shown was 3.92.152.3, then you would put the following into your web browser:
http://3.92.152.3:8080
You should see the GUI.

Challenge
Deploy sample.war Version 1 via the CLI
You must deploy
sample.warvia the CLI, not the GUI. The file is located in the/files/version1/directory.Go to the application via a browser and test the application is working. The app can be found by going to the server's external IP address with :8080/sample appended to the URL.
For example, if the IP address shown for the lab was 3.92.152.3, then you would put the following into your web browser:
http://3.92.152.3:8080/sample

Deploy sample.war Version 2 via the CLI
You must deploy
sample.warvia the CLI, not the GUI. The file is located in the/files/version2/directory.Go to the application via a browser and test the application is working. The app can be found by going to the server's external IP address with :8080/sample appended to the URL.
For example, if the IP address shown for the lab was 3.92.152.3, then you would put the following into your web browser:
http://3.92.152.3:8080/sample
The application will have different text than the original application. It shows that it is Version 2.
