Joint Webinar with Severalnines: How to manage Galera Cluster using ClusterControl

Since its creation, Galera Cluster has established itself as the most popular high availability solution for MySQL and MariaDB users worldwide.

ClusterControl is the go-to automation and management system for Galera Cluster users.

And together, we’re going to walk you through all the different aspects that make Galera Cluster such a popular high availability solution for MySQL and MariaDB and how to best manage it with ClusterControl.

We’ll hear about the latest features of Galera Cluster directly from Codership, the creators of Galera Cluster. And we’ll look at how to automate everything from deployment, monitoring (how about ASCII-art graphs?), backups, failover, recovery, rolling upgrades and scaling using the ClusterControl CLI (for a change, we also have a GUI of course).

Announcing Galera Cluster 5.7.18, 5.6.36 and 5.5.55 with Galera 3.21. Improvements to IPv6 Support, Bug Fixes and Changes to Repositories Structure

Codership is pleased to announce a new release of Galera Cluster for MySQL
consisting of MySQL-wsrep 5.7.18, 5.6.36, 5.5.55 and Galera 3.21, wsrep API
version 25.

Changes to Repositories Structure

With the new release the repository structure is changed to allow for
existence of all of the wsrep-patched mysql versions currently supported:
5.5 through 5.7.

Thus the repository layout requires from the user to adjust his or her
repository configuration to accomodate those changes. In order to have the
MySQL-wsrep and Galera library installed, one would need to add the following
repositories:

1. Galera-3 repository for galera library:
e.g. http://releases.galeracluster.com/galera-3/DIST/

Here DIST is Linux distribution (ubuntu, centos, …).

The latest version of Galera for FreeBSD is available in FreeBSD Ports
