MySQL High Availability: DRBD Configuration and Deployment Guide

There are many different ways of achieving high availability for MySQL. This Guide introduces DRBD (Distributed Replication Block Device), one of the leading solutions for MySQL HA (High Availability), offering users:

• An end-to-end, integrated stack of mature and proven open source technologies, fully supported by Oracle;
• Automatic failover and recovery for service continuity;
• Mirroring, via synchronous replication, to ensure failover between nodes without the risk of losing committed transactions;
• Building of HA clusters from commodity hardware, without the requirement for shared-storage.
