How to solve MySQL master-slave replication error
Article Introduction:The MySQL database is a critical component of modern software development, especially when we need to process large amounts of data and queries. MySQL provides a master-slave replication mechanism that allows us to copy data from the master server to multiple slave servers to achieve high availability and high-performance applications. However, when using master-slave replication, we often encounter some errors. This article will introduce how to solve MySQL master-slave replication errors. 1. What is MySQL master-slave replication? In MySQL, master-slave replication is a data replication technology that allows us to copy a My

What is mysql master-slave replication
Article Introduction:In mysql, master-slave replication means that data can be copied from a MySQL database server master node to one or more slave nodes. Asynchronous replication is used by default. The benefits of using master-slave replication: 1. Let the master database be responsible for writing and the slave database be responsible for reading. When the master database locks the table, the normal operation of the business can be ensured by reading from the slave database; 2. Hot backup of data can be done; 3. Expanding the architecture can reduce the frequency of disk I/O access and improve the I/O performance of a single machine.

Master-slave replication and high availability architecture in MySQL
Article Introduction:Master-slave replication and high-availability architecture in MySQL As Internet applications and data volumes continue to grow, the high availability and scalability of the database are becoming more and more important. As a widely used open source relational database, MySQL provides master-slave replication and high-availability architecture solutions. Master-slave replication refers to the process of using a MySQL database instance as the master database and replicating its data to one or more slave databases (slave). This replication method can achieve redundant backup of data and separation of reading and writing.

What is the principle of master-slave replication in MySQL
Article Introduction:Preface In the actual production environment, if the reading and writing of the MySQL database are all operated on a database server, it will not be able to meet the actual needs in terms of security, high availability, or high concurrency. Generally, it must be done through Master-slave replication is used to synchronize data, and read-write separation is used to improve the concurrent load capacity of the database. 1. Master-slave replication concept Master-slave replication is the basic technology provided by MySQL. The process of master-slave replication: binlog binary log (in addition to querying, other change-related operations will be recorded in the binlog), relaylog log and three threads (master One thread and two threads of slave). The main library (master) provides external data addition, deletion and modification

What are the three replication modes of Mysql master and slave?
Article Introduction:MySQL asynchronous replication MySQL asynchronous replication is the default replication mode during the master-slave replication process. Master-slave replication involves three threads, masterI/O thread, slaveI/O thread, and slavesql thread. Because it is asynchronous replication, the submission of the master transaction does not need to be confirmed by the slave. That is, after the master I/O thread submits the transaction, it does not need to wait for the reply confirmation from the slave I/O thread. The master does not guarantee that the binlog will be written to the relaylog; After slaveI/O writes the binlog to the relaylog, it is executed asynchronously by the slavesql thread and applied to slavemysql. slaveI
