Galera Cluster consists of two parts: the Galera Replication Library (galera-3) and a version of MySQL extended with the Write Set Replication (WSREP) API (mysql-wsrep).
Galera Cluster is available as targeted packages and package repositories for a number of Linux distributions, including Ubuntu, Red Hat, Debian, CentOS, OpenSUSE and SLES, as well as FreeBSD. Obtaining packages using a package repository eliminates the need to download individual files and facilitates the deployment and upgrade of Galera nodes.

The Galera Manager
In our latest release of Galera Manager, we have provided the ability for Galera Manager to monitor existing, pre-installed MySQL and MariaDB clusters. This means that you are no longer limited to using Galera Manager in an Amazon Web Services (AWS) Elastic Compute Cloud (EC2) environment, nor are you limited to using the command line for Galera Cluster monitoring.
Galera Manager provides charts for monitoring the host and database metrics, to ensure the proper and efficient functioning of your cluster. There are over 620 metrics to choose from. Galera Manager is fully web-based, and will work in any standard web browser to administer and monitor your clusters to make sure that your set up is healthy.
Instead of monitoring your Galera Clusters with the command line you could use the new Graphical User Interface (GUI) and download the installation software for Galera Manager by clicking the installer button below and registering with our site. You may also read our documentation on Galera Manager.
MariaDB Galera Cluster integrates Galera replication to provide a clustered version of MariaDB, an enhanced, drop-in replacement for MySQL developed by the MariaDB Foundation.
