MySQL master-slave replication, mysql master-slave Original article published on cu: Reference: This article involves the principle of MySQL master-slave replication and a simple verification of master-slave replication.I. MySQL master-slave replication Principle 1. Master-slave replication architecture Diagram Three

There is often a need to operate databases on the Internet to unify similar database applications across cities across the country. The data changes on one node are not only reflected locally, but also to the remote end. The replication technology provides users with a way to quickly access Shared data.I. Prerequisites for Database Replication 1. The database supports advanced replication.You can log on to

oracle| Script | data | database Oracle database replication Common scripts (Shi July 30, 2001 17:30) Oracle data replication is a relatively mature technology in Oracle database products and is an important part of the entire distributed computing solution. For database systems with replication environments, as well as Oracle DBAs, there is also a person who is

First, MySQL master (called Master) from (called slave) Copy principle: (1). master records data changes to the binary log (binary log), which is the Log-bin specified file (These records are called binary log events binary log event)(2). Slave copy Master's binary log events to its relay logs (relay log)(3). Slave redo the event in the relay log, changing the data that reflects it (the data repeats itself) Attached schematic diagram: Second, the MySQL master-slave

Label:5.2 Understanding actual impact and performanceIn this chapter, we have discussed the actual impact as well as the performance impact. But is there any good theoretical example? Let's do a simple benchmark test to see how replication is done. We do such tests to show you that the levels of endurance are not just a minor topic, but they are critical to performance. Let's assume a simple test: In the following scenario, we have connected to two eq

Building an AR (multimaster symmetric replication) is not very troublesome. Pay attention to the following steps:There is often a need to operate databases on the Internet to unify similar database applications across cities across the country. The data changes on one node are not only reflected locally, but also to the remote end. The replication technology provides users with a way to quickly access Share

1.Redis replication principle and Optimization 1.1 Redis standalone problem 1.1.1 machine failureThe deployment of a Redis node on a server, if the machine has a motherboard damage, hard disk damage and other problems, can not be completed in a short time repair, you can not process Redis operations, this is a possible problem of single machineSimilarly, the server is functioning properly, but the Redis master process has a down-time event where only

Label:In the previous article, "MySQL database Transaction and Replication" analyzes how to ensure the consistency between binlog and transactional data during MySQL replication, this paper further analyzes the need to consider what aspects are needed to ensure the data consistency of master and slave after the introduction from the library.Native Replication Sch
