Scenario A: 5 Nodes

Scenario A: 5 Nodes#

This five nodes scenario (depicted in Fig. 2) involves the presence of a single tenant.

Before starting the installation, bear in mind to:

  • Always start with the installation of Mesh and Directory Roles

  • When installing multiple Roles on a Node (for example Proxy and MTA like in ), the tasks listed in Bootstrap Carbonio and Join Carbonio Mesh steps can be made only once, after all packages of the Roles have been installed

Note

You can skip the installation of Nodes 4 and 5 if you do not need Docs Editor, Files, Chats, and Video Calls.
