Work Stream Collaboration (Chats)#

The Work Stream Collaboration (Chats) Role adds the chat functionality to Carbonio CE.

# apt install postgresql-client carbonio-message-dispatcher \
  carbonio-ws-collaboration-ce service-discover-agent
# dnf install carbonio-message-dispatcher \
  carbonio-ws-collaboration-ce service-discover-agent

Bootstrap Carbonio CE#

Execute:

# carbonio-bootstrap

The bootstrap command will execute a number of tasks and will set up the node. At the end, you will be prompted with a menu and, if you already configured all, you only need to click y for confirmation.

On RHEL 9 only, restart the node to ensure that Carbonio CE service management come under the control of systemd:

# reboot

During the process, you need to provide these values, which you can retrieve from the first Mesh and Directory node.

  • Ldap master host is the FQDN of the first Mesh and Directory node, (example: ldap-mstr.example.com)

  • Ldap Admin password is obtained from the first Mesh and Directory node (ldap-admin-password)

Join Carbonio Mesh#

Carbonio Mesh will install as an agent, that connects and communicates with the server. The configuration for the agent is created by launching command

# service-discover setup-wizard

This command will:

  • ask for the IP address and netmask of the current Node

  • ask for the Carbonio Mesh secret, which is stored in file /var/lib/service-discover/password on the Directory Leader Node (i.e., the node on which the Mesh server is installed)

    In case the password is lost or the credential file becomes corrupted and unusable, you can reset them using the procedure detailed in section Carbonio Mesh Credentials.

Pending setups#

To complete Carbonio Mesh installation, run

# pending-setups -a

Hint

The secret is stored in file /var/lib/service-discover/password, which is accessible only by the root user.

The command will ask for the password stored in the /var/lib/service-discover/password on the Directory Leader Node (i.e., the node on which the Mesh server is installed).

Dispatcher DB Migration#

Initialise the message dispatcher

# PGPASSWORD=$DB_ADM_PWD carbonio-message-dispatcher-migration \
  carbonio_adm 127.78.0.10 20000

Restart the service

# systemctl restart carbonio-message-dispatcher

Enable the Work Stream Collaboration (Chats) UI#

The Work Stream Collaboration (Chats) role is disabled by default, you can enable it either from the Carbonio Admin Panel or from the command line by running as the zextras user the command

zextras$ carbonio prov mc default carbonioFeatureChatsEnabled TRUE

This command enables the chat for the default COS, but you can enable it only on selected COSes.

Restart the service

# systemctl restart carbonio-ws-collaboration

Status Check#

After the installation, you can check the status of Work Stream Collaboration (Chats) and all its dependencies by running command
