Preparing the vCenter Server


It's assumed that we have vCenter running at this point, and it has been configured with proper networking and storage to access it via our network and access VMs residing on the physical hosts. To begin with, we need to make sure the ports are open between vCenter and vC Ops. If there aren't firewalls in between, then you can skip this part. The ports to open are as follows:

  • 22: SSH for command-line management

  • 80: HTTP which is redirected to HTTPS

  • 443: HTTPS for GUI management

  • 1194: Tunnel between UI VM and Analytics VM

As you may know, vC Ops comes as vApp that consists of two virtual machines: the (UI) User Interface VM and the Analytics VM. The UI VM is what allows us to access the information, and the Analytics VM is the data collector that contains a Postgres database to store all the information. Because vC Ops comes as vApp, we can do some interesting things with IP addresses on vCenter to automatically assign IPs to our virtual machines within the vApp. We...
