Summary of points to note about gtid master and slave

In the process of implementing the mysql master-slave architecture, you can use the mysqldump method to build the master-slave. Mysqldump has generated GTID related information during the backup process, that is, these GTIDs can be skipped. For unskipped GTIDs, the IO thread will copy them to the slave server and be executed by the SQL thread. This article mainly demonstrates how mysqldump builds mysql master-slave in GTID mode. References for relevant knowledge points: Configuring MySQL GTID Master-slave replication Quickly build a slave database based on mysqldump Use mysqldump to export the database 1. How to add a slave database with GTID 1. If all the binlogs of the master are still there, after installing the slave, directly change the master to the master The principle is to directly obtain all gtid of the master and execute The advantage is simplicity The disadvantage is that if there are too many binlogs, it will take a long time to fully synchronize the data, and the master needs to enable GTID from the beginning. Summary: Applicable to situations where the master is newly created. 2

1. Build gtid master-slave based on mysqldump

Introduction: In the process of implementing the MySQL master-slave architecture, you can use the mysqldump method to build the master-slave. Mysqldump has generated GTID related information during the backup process, that is, these GTIDs can be skipped. For unskipped GTIDs, the IO thread will copy them to the slave server and be executed by the SQL thread. This article mainly demonstrates how mysqldump builds mysql master-slave in GTID mode.

2. MySQL GTID error handling summary

Introduction: MySQL GTID is a product evolved on the basis of traditional mysql master-slave replication, which ensures the uniqueness of each thing through UUID plus transaction ID. This method of operation means that we no longer need to care about the so-called log_file and log_Pos, but simply tell the slave library which server to find the main library from. It simplifies the master-slave setup and failover process, and is safer and more reliable than traditional replication. Since GTIDs are continuous without holes, when data conflicts occur in the master-slave library, they can be skipped by injecting empty things. This article mainly describes the error handling method of GTID master-slave architecture.

3. mysqldump quickly builds a specific library master-slave architecture (GTID)

Introduction: For a MySQL database with a small amount of data to build a master-slave architecture, it is a good choice to use the mysqldump tool to implement it. Combined with the MySQL GTID feature, it makes high availability a breeze. This article is a supplement to building gtid master-slave based on mysqldump. It mainly introduces the implementation of GTID master-slave based on multi-repository level, that is, not the entire instance level. The following is a detailed description and examples of this article.

4. Gtid-based mysql master-slave replication and mysql-proxy read-write separation

Introduction: mysql5.6 is based on gtid master-slave replication and mysql-proxy read-write separation. The GTID (GlobalTransactionIDs) introduced by MySQL5.6 makes the configuration, monitoring and management of its replication function more convenient. Easy to implement and more robust..

8. Mysql5.6.21-GTID master-slave replication

Introduction: What is GTID: GTID (global transaction id) is the number of a submitted transaction and is a globally unique number . Components: UUID+TID What is UUID: the unique identifier of the Mysql instance. What is TID: TID represents the number of transactions that have been committed on this instance, and increases monotonically as transactions are committed. Example: 6dec6fd5-eb1f-
