option automatically turns off the lock table functionDo not know the translation is right, make a look at it ~ ~Simply put, is the master-slave replication in the full amount of backup, this option can automatically help us lock the table and identify the Binlog critical file, we do not need to lock the table, then look at the critical file number, and then perform the change

MySQL replication, mysql master-slave Replication Replication refers to the upload of DDL and DML operations in the primary database to the replication server (also called slave server) through binary logs, and then re-Execute (also called redo) these logs on the server ), i

First, Mysql 5.6 new features....Improvements to replication features⒈ supports multi-threaded replication, (slave-parallel-workers=0 0: Disables multithreading;) it actually turns on the corresponding independent thread for each database. That is, each library has a separate (SQL thread), if the online business, only one database or most of the pressure on the individual database, multi-threaded concurrent

The master/slave (master/slave) default engine is inconsistent, causing the replication to fail. The colleague told me that the replication of one slave server is interrupted.

1. First download the latest version of MySQL Server (http://dev.mysql.com/downloads/windows/installer/) 2. Install MySQL server on two machines MYSQL 1:192.168.0.104 (hereinafter referred to as 104) MYSQL 2:192.168.0.103 (hereinafter referred to as 103) 3. Configure MySQL server to start binary Logging.Add the following configuration information in the 104 My.ini file (typically in C:\PROGRAMDATA\MYSQL\MYSQL Server 5.6\my.ini) [Mysqld]Log-bin=mysql-binServer-id=1 Add the following configuration

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 wi

The ultimate goal of replication is to keep the data of one server in sync with the data of another server, which has reached data redundancy or service load balancing. A primary server can connect to multiple slave servers, and from the server it can also be the primary server. The master and slave servers can be located in different network topologies, and because of the powerful

This article describes the high availability of mysql master/master replication + keepalived (using VIP to access the database prompts that connection is not allowed), which has some reference value. let's take a look at it. Mysql master-master

I. The master-slave replication process of mysql requires at least two mysql service nodes. The master-slave replication framework of mysql is generally a master-slave multi-slave mode, which is summarized from multiple data centers to the data center mode, the

1. IntroductionMaster-slave replication is the most common way to replicate MongoDB. This method is very flexible and can be used for backup, failure recovery, read scaling, and so on.The most basic way to set up is to establish a master node and one or more slave nodes, each from the node to know the address of the master node. The primary server is started by r

The original meaning of replication's English word is "copy", the replication file is the last file of my analysis in the data directory, enough to explain his importance, the code quantity 1800 +, indeed very difficult to chew. Can only say that I look at the code down the general impression of it, I want to draw a structural map to the various APIs in this diagram, which I can not really do at present. When it comes to
