MySQL Cluster: The Latest Developments in Management, Free webinar

On Thursday 23rd January, Thomas Nielsen and I will be hosting a webinar explaining the latest developments in managing MySQL Cluster. As always the webinar is free but please register here.

Note that we’ll be covering what’s new in MySQL Cluster Manager 1.3 which went GA this week.

By their very nature, clustered environments involve more efforts and resources to administer than standalone systems and this holds true for MySQL Cluster, the database designed for web-scale throughput with carrier-grade availability.

The MySQL Cluster Auto-Installer guides you through defining and running a well configured MySQL Cluster database – …

MCM 1.3 is GA – Importing a running Cluster into MySQL Cluster Manager


MySQL Cluster Manager 1.3.0 is now Generally Available and can be downloaded from the Oracle Software Delivery Cloud. The release contains a number of enhancements including performance improvements, handling larger clusters and of course bug fixes. The other big feature is that you can now import an existing, running MySQL Cluster instance into MCM without having to stop it first – this is the topic for this post.

In the past, we had a nice browser-based tool (the MySQL Clster Auto-Installer) to get a well configured cluster up and running (tuned to your environment) and we also had MySQL Cluster …

Deploying an Active-Active FreeRadius Cluster with MySQL NDB or Galera

January 6, 2014 By Severalnines

MySQL Cluster is a popular backend for FreeRADIUS, as it provides a scalable backend to store user and accounting data. However, there are situations when the backend database becomes a centralized datastore for additional applications and services, and needs to take a more general-purpose role. NDB usually works very well for FreeRADIUS data, but for wider use cases and reporting type applications, InnoDB can be a better storage engine. For users who need to keep their data in InnoDB and still benefit from a highly available clustered datastore, Galera Cluster can be an appropriate alternative.

In this post, we will show you how to deploy FreeRadius both with MySQL Cluster and Galera Cluster to store user and accounting data. All servers are running CentOS 6.4 64bit.

New Webinar: Repair and Recovery for your MySQL, MariaDB and MongoDB/TokuMX Clusters

December 19, 2013 By Severalnines


Database clusters are pretty sophisticated distributed systems with complex dependencies between nodes. The failure of a node will generally impact the overall cluster, as the remaining nodes need to reconfigure themselves to continue to operate without the failed node. Since re-introducing a node will also affect the existing cluster, the timing could therefore be dependent on the state of the other nodes in the cluster. Repair and restarts often needs to be performed in a particular order in compliance with the redundancy model of the cluster so as not to jeopardize the normal functioning of existing nodes.
