Set up Multiple Carbonio Mesh Servers

Set up Multiple Carbonio Mesh Servers#

Within a Carbonio CE Multi-Server installation, it is possible to install multiple Carbonio Mesh servers, provided they are in odd numbers, e.g., 1, 3, 5 (or even more), because they can always find a quorum and avoid deadlocks.

Requirements#

In order to setup additional Carbonio Mesh servers, you need:

  • to have already installed and configured package service-discover-server (i.e., first Carbonio Mesh server) on one node

  • the /etc/zextras/service-discover/cluster-credentials.tar.gpg file created in the set up of the first instance of service-discovery

Moreover, as mentioned before, make sure to install an odd number of Carbonio Mesh servers.

Installation#

Instructions to install multiple Carbonio Mesh servers are the same for each new server installed, simply repeat the following procedure on each of them.

  1. Install the software package.

    # apt install service-discover-server

    # dnf install service-discover-server

  2. Copy the /etc/zextras/service-discover/cluster-credentials.tar.gpg file from the first Carbonio Mesh server

  3. Launch the setup:

    # service-discover setup-wizard

Repeat all the steps above on another node of the Multi-Server.
