This article mainly introduces "how to achieve Redis cluster mechanism and Redis architecture evolution". In daily operation, I believe many people have doubts about how to achieve Redis cluster mechanism and Redis architecture evolution. 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 about "how to achieve Redis cluster mechanism and Redis architecture evolution". Next, please follow the editor to study!

Replication (master-slave replication)

Redis's replication mechanism allows slave to transfer copies from master to a complete data backup over the network, thus achieving the master-slave mechanism. In order to implement master-slave replication, we prepare three redis services, named master,slave1,slave2 in turn.

Configure the primary server

In order to test the effect, we first modify the port information of the configuration file redis.conf of the main server

1. Port 6300 configuration slave server

The configuration related to replication is relatively simple, just add the following line to the configuration file of slave. You just need to change the ip address and port number.

1. Slaveof 192.168.1.1 6379

Let's first modify the port information and slave server configuration of redis.conf from the configuration file of server 1.

1. Port 63012. Slaveof 127.0.0.1 6300

We then modify the port information and slave server configuration of redis.conf from the configuration file of server 2.

1. Port 63022. Slaveof 127.0.0.1 6300

It is worth noting that, starting with the redis2.6 version, slave supports read-only mode and is the default. You can configure it through the configuration item slave-read-only.

In addition, if master sets the password through the requirepass configuration item, slave needs to verify the password for each synchronization operation, and you can add the following configuration item to the slave configuration file

1. Masterauth at this point, the study on "how to achieve the evolution of Redis cluster mechanism and Redis architecture" 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!
