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 with cloud providers (Amazon Web Services AWS, DigitalOcean), you can also deploy clusters on user provided hosts (on premise or in the cloud) or you can also monitor hundreds of performance metrics of your existing cluster with a graphical user interface.
- Make sure that Galera Manager host of your choice satisfies the following conditions:
- can be reached by IP address or domain name from the cluster nodes (i.e. it is not your laptop behind NAT)
- has domain name configured if you desire secure connections (HTTPS)
- has ports 80, 8081 or 443, 9091 open for HTTP or HTTPS connections respectively.
- Download the installer.
- Run: chmod a+x gm-installer && sudo ./gm-installer install
