  • Support for PostgreSQL 15, MongoDB 6.0, MariaDB 10.11, and MS SQL Server 2022.
  • Support for RedHat 9, AlmaLinux 9, and RockyLinux 9.
  • General Availability of our new web frontend – ClusterControl v2
    • Mail notifications, Certificate management
    • Advisors, Incident management services, Topology View


Enterprise Vendors

ClusterControl now supports using Enterprise vendors for PostgreSQL and MongoDB. You can manage and monitor EDB Postgres Advanced Server and MongoDB Enterprise clusters by using their enterprise repositories when provisioning databases. You need a valid repository token (depending on the vendor) in order to use the enterprise packages.

The s9s CLI adds two new vendor (–vendor) options:

  • enterprisedb for EDB Postgres Advanced Server
  • mongodbenterprise for MongoDB Enterprise

ClusterControl v2.0 – New web frontend

We have been migrating the feature set of the ClusterControl GUI (v1) to a new web frontend. This is a completely rewritten web application that aims to modernize the UI and improve the user experience and ease of use.
It is now in a state where we have feature parity with the old user interface. You can start using ClusterControl (GUI) v2 without having to rely on the functionality of the old web application.

‘CCv2’ is now the default web application when you install ClusterControl following the product download page instructions. The old web application ‘CCv1’ is still accessible until the end of the year at which time it will no longer be supported.

Upgrade to CCv2

You can upgrade/move from the CCv1 web application to the CCv2 web application with a few easy steps (existing ClusterControl installation). This setup will still provide access to the old ‘CCv1’ user interface while the new web application is accessible at another port.

Upgrade notes:

  • The 3rd party notifications configurations for PagerDuty, Opsgenine, Slack, etc. need to be manually re-created in CCv2 and removed from CCv1.
  • The DB Status and DB Variables pages are coming in a future CCv2 patch.


Steps described in the following sections should be performed on the ClusterControl node unless specified otherwise.

Red Hat/AlmaLinux/RockyLinuxDebian/Ubuntu
$ yum clean all
$ yum install clustercontrol2
$ systemctl restart httpd

Open the web browser and go to https://{ClusterControl_host}:9443. Log in with your user credentials used with ‘CCv1’

$ apt update
$ apt install clustercontrol2
$ systemctl restart apache2

Open the web browser and go to https://{ClusterControl_host}:9443. Log in with your user credentials used with ‘CCv1’
