6. Bring Up the Whole System
The steps below are a checklist you can use to ensure the cluster works properly:
1. Make sure all the nodes are not running.
2. Start each node individually.
3. Check whether you can log in to each node. Open Zephyr on each node in the browser to make sure it starts and is configured properly.
4. Verify the system at the load balancer entry point. Log in to Zephyr in two different browsers by using the load balancer URL:
In the first browser, log in as an admin user.
In the second browser, log in as the same user - the user in the first browser should be logged off.
If everything works as expected, the system is ready for use.
