Example: 5 nodes Installation

Example: 5 nodes Installation#

This example involves the presence of a single tenant and is suitable for small infrastructure up to thousands of accounts, with complete set of Carbonio functionalities.

The Components installed on the 5 Nodes are:

  • Node 1: Mesh & Directory, Database, and Monitoring

  • Node 2: MTA AV/AS and Proxy

  • Node 3: Mailstore & Provisioning, and Tasks

  • Node 4: Chats, Files, Docs & Editor, and Preview

  • Node 5: Video Server & Video Recording

Architecture#

The architecture of this scenario is depicted in the following diagram.

Network Configuration#

The following ports must be opened on the external network, i.e., they are required for proper access to Carbonio from the Internet.

Ansible Playbook#

This 5 Nodes scenario can be installed using Ansible: you need to setup a control node to run Ansible playbooks (please refer to section Prepare the Ansible Environment, then follow the directions on setting up the control node). To access the control node, execute the following command to log in (replace mail.example.com with the name or IP of the control node)

$ ssh root@mail.example.com

$ ssh -A root@mail.example.com

After you have logged in to the control node, download the Ansible inventory (see below this paragraph), replace the FQDN and values present in the file according to your planned Carbonio infrastructure.

Before installing, make sure each Node satisfies the Carbonio Requirements and you have carried out all Preliminaries tasks.

Once you edited the inventory, save it in a directory of your choice as carbonio-inventory. Now, you can run the script: from that directory execute the command

$ ansible-playbook zxbot.carbonio_install.carbonio_install \
-u root -i carbonio-inventory
