MHA (Master High Availability) for MySQL is a tool that automates failover and master recovery for MySQL replication setups. The manager node monitors MySQL servers and promotes a slave to master in case of failure, with minimal downtime. It is widely used in production systems requiring high availability and disaster recovery for MySQL clusters.

Features

  • Automatic MySQL master failover with low downtime
  • Manual and semi-automated switchover support
  • Detects replication consistency before promotion
  • Customizable failover hooks for scripting
  • Integration with existing MySQL replication setups
  • Email and log-based notifications
