MySQL Master-Slave architecture of the applicable scenario is read-write separation, written through the main library, read from the library, most of the scene is read more cases, a single master slave architecture can be very good to solve the problem of high reading pressure.

Overview replication is usually used to create a copy of the master node to ensure high availability by adding redundant nodes. Of course, replication can also be used for other purposes, such as reading and analyzing data on the slave node. In horizontally Scalable businesses, replication is easy to implement, mainly in the use of the master node for write operations, multiple slave nodes for read operatio

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.

In actual production and development, if multiple nodes coexist, You need to select the master node and implement ha automatic fault tolerance. I have thought about the writing method and shared it with you. Lease protocol, MySQL Acid High Availability primary selection solution design Applicable scenarios JAVA Implementation description Further Optimization There are many application scenarios in the system that are similar to the

In enterprises, the high availability of databases has always been the top priority of enterprises, many small and medium-sized enterprises are using MySQL master-slave scheme, a master and many from, read and write separation, but single-master single point of failure, switch from the library to the main library needs to be changed. Therefore, if it is a dual-

Mysql5.6 + Master/Slave settings (there are some gaps between the Master/Slave settings after mysql5.5 and those before 5.5, follow these steps to first enable the database port firewalls between the master and slave mysql servers before configuring the master and slave databases. Mysql5.6 +

Of course, the emergence of the GUID function of 5.6 has also brought infinite possibilities for multi-master, but this is a digress. This article mainly introduces a non-real-time multi-master Method for MySQL versions. Introduction: The original idea comes from a foreign DBA blog: http://thenoyes.com/littlenoise?

MySQL ReplicationMySQL replication refers to the transfer of DDL and DML operations on the main library to the library from the binary log, keeping the master and the data from the library in syncMySQL Master-slave Architecture: Advantages: Can cut the library when failure, read and write separation, perform other business from the library such as backup.1:master
