  To install the agent: 
  
  1. Login to your EC2 instance. 
  2. Paste the saved install command to the Ubuntu command line. 
  3. Press Enter. The installation should begin.
  
  You will be presented with a list of options to install, as shown below. An additional option, Infrastructure Agent, is always installed. Press Enter to select all of the options.

  Finally, you will be asked for the MySQL password. Type `root`.
  
  If all goes well, each installation should report `success`.
  
  
  If you are using the Multitier installation, you will have multiple EC2
  instances. The agent should be installed separately for each one.
