        • clustercontrol-controller 1.3.0-1240
      • ClusterControl UI:
        • New Install Software option for Galera Cluster with Create Database Cluster and Create Database Node
        • Default Yes act as before where ClusterControl provisions the database nodes with required packages and any existing packages could be uninstalled if required.
        • If set to No then no provisioning of packages or uninstallation of any existing packages are done. It is assumed that the DB nodes have been provisioned by for example a configuration management system with all required database packages. The create cluster/node jobs will then only provision out our Galera my.cnf file and then bootstrap the cluster without doing any provisioning of software. It is important that the mysql server process is stopped before running the job with install Software set to No.
          • MongoDB arbiter is now shown on the Nodes page.
      • ClusterControl Controller:
        • Correct wrong assets path. Fixes missing logo in operational reports.
        • Manual fix: Move /usr/share/cmon/assets/assets to /usr/share/cmon/assets.

    • clustercontrol-cmonapi 1.3.0-183
    • clustercontrol-nodejs 1.3.0-56
  • Key Management allows you to manage a set of SSL certificates and keys that can be provisioned on your clusters.
    • Create certificate authority certificates or self-signed certificates and keys.
    • Easily Enable and Disable SSL encrypted client-server connections for MySQL and Postgres based clusters.
  • Additional Operational Reports.
    • Generate an Availability Summary of uptime/downtime for your managed clusters and see node availability and cluster state history during the reported period.
    • Generate a backup summary of backup success/failure rates for your managed clusters.
  • Improved Security
    • From this version we are setting an unique Controller RPC API Token which enables token authentication for your managed clusters. No user intervention is needed when upgrading older ClusterControl versions. An unique token will be automatically generated, set and enabled for existing clusters.
    • Custom scripts/applications utilizing the RPC API need to pass the correct token for the clusters, see http://severalnines.com/downloads/cmon/cmon-docs/current/ccrpc.html... for details on how to pass the token correctly.
  • Create/Mirror Repository
    • Mirror your database vendor’s software repository without having to actually deploy a cluster. A mirrored local repository is used in scenarios where you cannot upgrade a cluster and must lock the db versions to use.
  • Additional Backup Retention Periods
    • Enable shorter retention periods.
  • MySQL based clusters
    • NDB/MySQL Cluster
      • Create a production setup of NDB/MySQL Cluster from ClusterControl.
      • Deploy Management Nodes, SQL/API Nodes and Data Nodes.
    • MySQL Replication/Standalone
      • Easily toggle read-only mode on and off for MySQL nodes.
  • MongoDB based clusters
