Get started with Percona XtraDB Cluster

This guide describes the procedure for setting up Percona XtraDB Cluster.

Examples provided in this guide assume there are three Percona XtraDB Cluster nodes, as a common choice for trying out and testing:

Node Host IP
Node 1 pxc1 192.168.70.61
Node 2 pxc2 192.168.70.62
Node 3 pxc3 192.168.70.63

Note

Avoid creating a cluster with two or any even number of nodes, because this can lead to split brain.

The following procedure provides an overview with links to details for every step:

It is recommended to install from official Percona repositories:

This includes path to the Galera library, location of other nodes, etc.

This must be the node with your main database, which will be used as the data source for the cluster.

Data on new nodes joining the cluster is overwritten in order to synchronize it with the cluster.

Although cluster initialization and node provisioning is performed automatically, it is a good idea to ensure that changes on one node actually replicate to other nodes.

To complete the deployment of the cluster, a high-availability proxy is required. We recommend installing ProxySQL on client nodes for efficient workload management across the cluster without any changes to the applications that generate queries.

Percona Monitoring and Management

Percona Monitoring and Management is the best choice for managing and monitoring Percona XtraDB Cluster performance. It provides visibility for the cluster and enables efficient troubleshooting.
