Deploy a Tomcat Application Statically
Welcome to this hands-on lab, where we'll deploy an application on Tomcat via the CLI in a static manner. 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 after first stopping Tomcat, then starting Tomcat again and noting what happens. After stopping Tomcat a second time, you will deploy a second version of the application, then start Tomcat yet again. The application's web page should show the new version of the application. 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.
Note: It may take from 3 to 10 mins after the hands-on lab has started before you can access the Tomcat server on port 8080.

Challenge
Stop Tomcat, Deploy Version 1 of `sample.war` via the CLI, Then Start Tomcat
You must deploy the
sample.warvia the CLI. To complete this task you are not to use the GUI and you must stop Tomcat first.The file is located here:
/files/version1/sample.war.Once the application is in the correct place, start the Tomcat server.
Go to the application via a browser and test to see if it's working. It can be found by going to the server's external IP address with :8080/sample at the end of 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

Challenge
Stop Tomcat, Deploy Version 2 of `sample.war` via the CLI, Then Start Tomcat
You must deploy the
sample.warvia the CLI. To complete this task you are not to use the GUI and you must stop Tomcat first.The file is located here:
/files/version2/sample.war.Once the file is in place restart Tomcat.
Go to the application via a browser and test to see if it's working. It can be found by going to the server's external IP address with :8080/sample at the end of 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 version 2.
