MySQL uses statement-based replication by default and is more efficient. Row-based replication is automatically selected as soon as it

This article will share with you a good tutorial on configuring Linux MySQL master-slave Replication (Replication) (MySQL Data Synchronization). Thank you for your reference. MySQL is an open-source relational database system. Replication is a process that replicates data from a MySQL database server (

The previous article thanks to "Mysql, MariaDB traditional master-slave cluster Configuration", the technology has been very mature. Starting from Mysql5.6 and MariaDB10.0, with the new master-slave scheme Gtid, but the two systems to this version of the branch, the implementation has been different, configuration methods are different, the following are describe

One, main library thread status (state) valueThe following list shows the most common states (show processlist) that may be seen in the State column of the Binlog dump thread of the primary server in master-slave replication. If the Binlog dump thread is not visible on the primary server, this means that replication is not running, that is, no slave hosts are cur

check bit, if the network transmission problems can be resumed, such as a breakpoint,Three. Master the Binlog file through a line called dump path to Slave, slave will receive an event written to a file called Relay log (relay log), and then according to relay log with a call applier something to commit ( Write datafile, and Binlog)The Binlog and relay log content is not always the same, because you can set the eventsize if there is a thing on

addition, to eliminate single point of failure (SPOF) at sites in different geographic locations, redundancy can be added to each master database, that is, a slave database is added to each master database; MMM (= Master-Master Replication Manager for MySQL) is a set of scr

MySQL replication (2) Master-Slave replication practices, mysqlmaster-slave1. Preparations First, prepare two machines to install mysql My version here is 5.1.73, mysql database installation refer to: http://www.cnblogs.com/tangyanbo/p/4289753.html Centos for linux The machines are: Master: 192.168.1.227 Slave: 19

Mysql master replication and mysql Replication The customer needs high availability in the project, and the database is a key part of high availability. I have studied the high availability of many mysql instances, using mysql cluster and mysql master-slave master-

made to tables on the server.1.1 MySQL Supported Replication types:(1): statement-based replication: SQL statements executed on the primary server execute the same statement from the server. MySQL uses statement-based replication by default and is more efficient.Row-based replication is automatically selected as soon

I. OverviewKeep one server's data in sync with other server data. Data from one master library can be synchronized to multiple repositories, and the repository itself can be configured as the main repository for other servers.Main applications:1) Data distribution2) Load Balancing3) Pseudo backup. Add more secure technical supplements based on backup4) High availability and failover. Avoid MySQL single point of failure5) Upgrade test. Before upgrading

the data from the node to ensure data consistency. If one of the nodes fails, the other nodes will immediately connect to the business without downtime. Features and benefits of MongoDB replication set Features of the replica set: n Nodes of a cluster Any node can be used as the master node All write operations are on the primary node Auto Fail-Ov

Objective: To enable two MySQL servers to provide synchronization services from each other.Advantages:1. The main advantage of MySQL's master-slave replication is that it synchronizes "backup" and the database on the slave is equivalent to a (basic real-time) backup repository.2. On the basis of master-slave replication
