Redis Server PHP Database

Title, there are several shopping sites (PHP), the order data scattered in different server databases (such as DB1,DB2), and the total Order database (db), easy to centralize management, operations on the DB need to be synchronized to DB1,DB2, and DB1,DB2 data need to update to the DB as real-time as possible. The basic implementation with timing plan +XMLRPC and the like can be achieved, but a bit clumsy waste of resources. Seek the Master experienced solution!
