Run the following commands in the terminal you just opened.
cd ~/environment/amazon-mq-workshop ./setup.sh source ~/.bashrc
After the above step is completed, close all terminals you see in Cloud9 workspace. Now you need to create 4 terminals to make it easier for you to run commands and observe output from those commands. Follow the instructions below
You need to split the windows into 4 windows chequered pattern. Click on the two icons as shown in the picture below. Click on the top icon first and then when a new menu opens click on the bottom icon as shown with red circle.
In each window, open a new terminal byclicking on + tab and select New Terminal as shown in the picture below.
Navigate to the projects root directory by running in EACH terminal.
Please make sure all terminals are in the /environment/amazon-mq-workshop directory.
You cloud9 screen should look like the screen below. Do not close the Cloud9 tab as you need this for rest of the workshop.
