Assignment 1: The Set up

Updating and initial configuration for monitor (server-04)

We will re-use the server-04 instance to deploy a monitoring and configuration center that allows us to keep control of our entire service in our virtual infrastructure.

1. You will have to adapt your server-04 to turn it into a monitoring and configuration center for all our deployed services. So, carry out the tasks required as follows:

   • First, update the system from debian repositories.

   • Then, make an “alias” for server-04 in the DNS service deployed in Lab1 (server-01). Also, be sure that /etc/hosts is properly updated on both servers:

     • Alias: monitor --> server-04

2. Configure every host (virtual instance) in our cloud environment so the access or command execution through the SSH service between each of the members can be “passwordless”

   • For user ‘root’ only,

   • On server-01, server-03, server-04 and server-05
