Recently, the redis cluster deployment has been used. By the way, you can learn a lot about redis.

1. Download redis and support the deployment of redis cluster from 3.0. tar xzvf redis-5.0.5.tar.gz

#Download the source code and extract it through tar zxvf
wget http://download.redis.io/releases/redis-5.0.5.tar.gz
#Compile the source code through make, and redis cli redis server will be generated under src
cd redis-5.0.5
make
#Note that compilation failure may occur
yum -y install gcc gcc-c++ libstdc++-devel
#Due to the allocator problem, there may be errors. libc is not the default allocator, but jemalloc is the default
#But if you don't have jemalloc and only libc, of course make is wrong
#So make with parameters
make MALLOC=libc

2. Here is a simple script to create a cluster, which is located in redis-5.0.5/utils/create-cluster/create-cluster. Through this script, you can deploy clusters of six nodes on a single server. If you need outside access, you can add the following commands. Note that the $${ip} $$in the script is the ip that can be accessed externally, and note that the - protected mode no in the start

#!/bin/bash

# Settings
PORT=30000
TIMEOUT=2000
NODES=6
REPLICAS=1

# You may want to put the above config parameters into config.sh in order to
# override the defaults without modifying this script.

if [ -a config.sh ]
then
    source "config.sh"
fi

# Computed vars
ENDPORT=$((PORT+NODES))

if [ "$1" == "start" ]
then

Start 6 redis instances through simple command. / create cluster start, port 30001-30006

. / create cluster create and enter yes to create a redis cluster

. / create cluster stop

. / create cluster clean clean clean all log, dump, aof and conf files

. / create cluster watch can monitor slot information
