Upgrade CP Server To The Latest Build

The procedure below describes how to update your Control Panel server to the latest build:

Update a Regular Control Panel Server


To update a Control Panel server to the latest build, run the following command:

/onapp/onapp-cp-install/onapp-cp-install.sh


Update High Availability Control Panel Servers


To update Control Panel servers in a high availability configuration to the latest build, use the following procedure:

Before updating ensure that the lsyncd service is not started during the whole CP upgrade procedure.

  1. In separate consoles, connect to all three CP servers and run the following command: 

    #  watch /etc/init.d/lsyncd stop

    This process should be running during the CP upgrade procedure and can be stopped after the upgrade is completed.

  2. Switch the cloud to maintenance mode at Control Panel > Sysadmin > Control Panel Maintenance.
  3. Run the Control Panel installer on all CP servers:

    # /onapp/onapp-cp-install/onapp-cp-install.sh
  4. Switch all nodes back online by running the following command once on any of the nodes:

    # crm configure property maintenance-mode=false


  5. Enable file synchronization on all nodes by running the following command once on any of the nodes:

    # crm resource start lsyncd-cluster
  6. Check that all services are running:

    # crm_mon -1r
