MySQL Semi-synchronous Replication (Semi-synchronous Replication) in enterprise applications, MySQL often uses a master-slave architecture or a master-master architecture to achieve load balancing of MySQL servers, improves the performance of the MySQL server. the key is that MySQL Data Synchronization and replication can be implemented to provide a convenient me
If you have previously thought that replication slave is a necessary permission for replication, then you are mistaken, and for security generally you need replication slave. If you set up replication slave,replication client replication
transaction; binlog_format=mixed # master-slave copy format (mixed,statement,row, default format is statement); expire_logs_days=7 # Number of days the binary log is automatically deleted/expired. The default value is 0, which means it is not automatically deleted; slave_skip_errors=1062 # Skip all errors encountered in master-slave replication or specify types of errors to avoid slave-side
Copying an array refers to generating a new array with the same content as the original array. Array assignment is frequently used and important.There are two replication methods: shallow replication and deep replication. This concept is not unique to arrays. There are some differences between the replication mode and

Analysis of MySQL replication and optimization principles and methods, mysql replication Optimization PrinciplesI. Introduction
MySQL's built-in replication solution brings the following benefits:
Data backup.
Server Load balancer.
Distributed Data.
Concepts:
Master: the database to be copied.
Slave: the database that copies host data.

I. Principles of MySQL master-slave Replication
1. mysql replication process: each time a write operation is executed, it will save a copy to its own database. At the same time, this write operation will also be stored in a binary log file, and save them as events. Therefore, each write operation or modification operation on the front-end data in this database will save an event, we will send the event to a
First, IntroductionIn the master-slave copy of the previous article: http://www.cnblogs.com/lay2017/p/9043985.htmlWe learned that MySQL writes logs through master, slave reads and executes the log content to achieve slave data consistent with master. So based on this principle, we can realize the replication function of two master.Broadly as follows:1, both master open Log-bin write log2, ID to repeat3. Configure the tables to be copied4, two master r
Master-Slave replication principle
MySQL replication is an asynchronous replication process that replicates from master to one or more slave.
The entire replication process between master and slave is done primarily by three threads, one IO thread on the master side and two threads (SQL thread and IO threa

A Brief Introduction to MySQL multi-source replication and mysql Replication
Recently, ORACLE released several new features in the latest version of Mysql5.7.2. Most of the improvements are in terms of database performance and replication-related features. This new version will bring us incredible results.
In this article, I will try to understand the working pri
Label:After performing your first instant recovery (pitr,point-in-time-recovery), we are ready to work on a real replication setup. In this chapter, you will learn how to set up asynchronous replication and flow. Our goal is to ensure that you can achieve higher availability and higher data security. In this chapter, we will discuss the following topics: • Configuring asynchronous
OverviewRedis supports a simple and easy-to-use master-slave replication (Master-slave replication) feature that allows the slave server (slave server) to be an exact replica of the master server. Here are a few important aspects of the Redis replication feature:

1. IntroductionAs one of the most widely used databases in the world, MySQL is one of the reasons why it is free. But what is not to be overlooked is that its own function is indeed very powerful. With the development of technology, in the actual production environment, the single MySQL database server can not meet the actual demand. At this point the database cluster is a good solution to this problem. With MySQL distributed cluster, you can build a high-concurrency, load-balanced cluster Serve
Practice Process:

Configure S1, start Group Replication
Configure S2, add to Group
Configure S3, add to Group
