This article mainly introduces "the detailed explanation of the method of MySQL semi-synchronous replication". In the daily operation, I believe that many people have doubts about the detailed explanation of the method of MySQL semi-synchronous replication. The editor consulted all kinds of materials and sorted out simple and easy-to-use operation methods. I hope it will be helpful to answer the doubts of "detailed explanation of the method of MySQL semi-synchronous replication". Next, please follow the editor to study!

1. Install the relevant plug-ins on the master and slave nodes respectively

Master > INSTALL PLUGIN rpl_semi_sync_master SONAME 'semisync_master.so'

Slave > INSTALL PLUGIN rpl_semi_sync_slave SONAME 'semisync_slave.so'

2. Enable semi-synchronous replication

In the configuration file on master, add

Rpl_semi_sync_master_enabled=ON

Add to the configuration file of at least one slave node

Rpl_semi_sync_slave_enabled=ON

Then restart the mysql service to take effect.

Alternatively, you can start its related functions dynamically on the mysql service:

Master > SET GLOBAL rpl_semi_sync_master_enabled = ON

Slave > SET GLOBAL rpl_semi_sync_slave_enabled = ON

Slave > STOP SLAVE IO_THREAD; START SLAVE IO_THREAD

3. Confirm that the semi-synchronization feature is enabled

Master > CREATE DATABASE mydb

Master > SHOW STATUS LIKE 'Rpl_semi_sync_master_yes_tx'

Slave > SHOW DATABASES

At this point, the study of "detailed explanation of the method of semi-synchronous replication of MySQL" is over. I hope to be able to solve your doubts. The collocation of theory and practice can better help you learn, go and try it!
