The editor in this issue will bring you the steps of building and configuring redis clusters, and analyze and describe them from a professional point of view. I hope you can get something after reading this article.

Redis cluster needs at least 3 nodes, because the voting fault tolerance mechanism requires more than half of the nodes to think that a node is dead, so two nodes cannot form a cluster.

A cluster with three nodes in a cluster, with one master and one standby for each node. Six virtual machines are required. Build a pseudo-distributed cluster and simulate it with 6 redis instances.

1. Install the ruby environment

Yum install ruby//ruby Runtime Environment yum install rubygems//ruby package Manager uploads redis-3.0.0.gem to the server (the package on which redis-trib.rb runs) gem installe redis-3.0.0.gem (installs the dependent package)

two。 Set up a cluster

(1) copy bin

Mkdir redis-cluster cd rediscp-r bin.. / redis-cluster/redis01 / / copy

(2) configuration file modification

Cd.. / redis-cluster/redis01/rm-f dump.rdb (delete snapshot file) vim redis.conf

Modify:

Port 7001cluster-enabled yes

(3) create six nodes

Cp-r redis01/ redis02 (all the way to 6) vim redis02/redis.conf (change the port number respectively)

(4) copy the cluster script to the cluster directory

Cd redis-3.0.0/src cp * .rb / usr/local/redis-cluster/

(5) run 6 redis instances

Vim startall.shcd redis01. / redis-server redis.confcd.. cd redis02. / redis-server redis.confcd.. cd redis03. / redis-server redis.confcd.. cd redis04. / redis-server redis.confcd.. cd redis05. / redis-server redis.confcd.. cd redis06. / redis-server redis.confcd. / startall.sh

(6) create a cluster

/ redis-trib.rb create-- replicas 1 192.168.25.153VR 7002 192.168.25.153VR 7002 192.168.25.153VR 7004 192.168.25.153VR 7005 192.168.25.153VR 7006 above are the steps for building and configuring redis cluster shared by Xiaobian.
