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
Galera Manager allows you to create fully managed clusters in Amazon Web Services, and you can also deploy clusters on user provided hosts (on premise or in the cloud) and you can also fully monitor your existing cluster. The GUI has the concept of a managed node (your typical MySQL instance) and managed host (your typical Linux instance) which you use to deploy Galera Cluster in Amazon EC2, a managed node and a monitored host for user provided hosts (on premise or in the cloud) and just a monitored node and host for existing Galera Clusters that you would like monitored, in the new and improved cluster deployment wizard.
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.
