capttofu: MySQL Multi-Master Replication

Slony-I is a "master to multiple slaves" replication system with cascading and failover. The big picture for the development of Slony-I is a master-slave system that includes all features and capabilities needed to replicate large databases to a reasonably limited number of slave systems. Slony-I is a system for data centers and backup sites, where the normal mode of operation is that all nodes are available.

This tutorial describes how to set up database replication in MySQL. MySQL replication allows you to have an exact copy of a database from a master server on another server (slave), and all updates to the database on the master server are immediately replicated to the database on the slave server so that both databases are in sync. This is not a backup policy because an accidentally issued DELETE command will also be carried out on the slave; but replication can help protect against hardware failures though.
