MySQL supports unidirectional and asynchronous replication. One server acts as the master server during the replication process, and one or more other servers act as slave servers. The master server writes updates to the binary log file and maintains an index of the log file
Lab environment:
Master node IP Address: 172.16.2.16
Slave node IP: 172.16.2.17
The mariadb version is 5.5.36 and is installed in binary mode. The installation is complete.
Purpose:
Learn about master-slave replication and how each node works.
Procedure:
1. The
Although Redis has excellent performance, we can still master/slave this simple architecture, read and write separation, further mining redis performance, improve system availability.
Redis How to do master and slave copy. Redis replication is implemented primarily through
1.MySQL master-slave copy and read/write separation principleFirst, let's look at a diagram:
Operations that affect the MYSQL-A database are written to the local log system A after the database is executed.Suppose that the real-time database event operation in the log system will change, on the Mysql-a 3306 port, sent to Mysql-b via the network.After the Mysql-b is received, the local log syste

Master-slave replication is an old topic. I will not talk about the details of master-slave replication here. I will focus on the differences between the logs and locations in show slave
This experiment demonstrates the asynchronous replication of mysql. What is asynchronous replication? That is, when a statement is started, the master server does not wait until the slave server is executed.
