Configure several Carbonio Mesh servers

Configure several Carbonio Mesh servers

Since they can always find a quorum and avoid deadlocks, several Carbonio Mesh servers can be installed within a Carbonio Multi-Server installation if their numbers are odd, such as 1, 3, or 5 (or even more).


You require the following in order to set up more Carbonio Mesh servers:

  •  service-discover-server  having been set up and installed on one node (see Section SRV2: Directory Server, DB connection, and Carbonio Mesh Server)
  • the cluster-credentials.tar.gpg file produced during the initial setup of service-discovery, located at  /etc/zextras/service-discover/cluster-credentials.tar.gpg 

Additionally, as previously indicated, be careful to set up an odd number of Carbonio Mesh servers.


The steps for installing several Carbonio Mesh servers are the same for each new server deployed; you only need to carry out the steps in the previous section on each one.

1. Set up the software bundle.

2. The first Carbonio Mesh server’s /etc/zextras/service-discover/cluster-credentials.tar.gpg  file should be copied.

3. Start the setup:

# service-discover setup-wizard

On a different Multi-Server node, repeat the previous procedures.
