本文默认选择centos7做为安装，选择的机器为两台

依赖与下载

1.安装编译依赖
yum install -y gcc gcc-c++ libstdc++-devel

2.安装包下载
wget https://download.redis.io/releases/redis-6.2.6.tar.gz
tar xf redis-6.2.6.tar.gz -C /usr/local/src/

3.编译
cd /usr/local/src/redis-6.2.6/ && make && make install

安装

1.创建集群配置目录信息
mkdir /usr/local/redis-cluster/{7001,7002,7003,data,pid}/{bin,conf,logs} -p
mkdir /usr/local/redis-cluster/{7004,7005,7006,data,pid}/{bin,conf,logs} -p

2.配置文件创建，如下ip地址以及端口记得手动修改
#拷贝原文件到每个集群端口中,仅列举两次命令
cp /usr/local/src/redis-6.2.6/redis.conf /usr/local/redis-cluster/7001/redis_7001.conf
cp /usr/local/src/redis-6.2.6/redis.conf /usr/local/redis-cluster/7004/redis_7004.conf


#修改配置文件/usr/local/redis-cluster/7001/redis_7001.conf
bind 172.xx.xx.xx	#监听地址，选择本地ip地址
protected-mode no	#关闭保护模式
port 7001		#端口号记得跟随配置文件修改
daemonize yes		#后台运行
pidfile /usr/local/redis-cluster/7001/var/redis_7001.pid				#pid存放路径记得跟随配置文件修改
logfile /usr/local/redis-cluster/7001/logs/redis_7001.log				#日志存放路径记得跟随配置文件修改
always-show-logo yes											 #是否显示总日志
dbfilename redis_7001.rdb												#持久化数据文件名称
dir /usr/local/redis-cluster/7001/data										#持久化数据文件存放路径
cluster-enabled yes										#开启集群模式
cluster-config-file nodes_7001.conf						 #集群模式配置文件名称
cluster-node-timeout 15000								#集群超时时间

3.启动命令
[root@redis01 redis-cluster]# /usr/local/src/redis-6.2.6/src/redis-server /usr/local/redis-cluster/7001/redis_7001.conf 
[root@redis01 redis-cluster]# /usr/local/src/redis-6.2.6/src/redis-server /usr/local/redis-cluster/7002/redis_7002.conf 
[root@redis01 redis-cluster]# /usr/local/src/redis-6.2.6/src/redis-server /usr/local/redis-cluster/7003/redis_7003.conf 
[root@redis02 redis-cluster]# /usr/local/src/redis-6.2.6/src/redis-server /usr/local/redis-cluster/7004/redis_7004.conf 
[root@redis02 redis-cluster]# /usr/local/src/redis-6.2.6/src/redis-server /usr/local/redis-cluster/7005/redis_7005.conf 
[root@redis02 redis-cluster]# /usr/local/src/redis-6.2.6/src/redis-server /usr/local/redis-cluster/7006/redis_7006.conf

4.创建集群
[root@redis01 redis-cluster]# /usr/local/src/redis-6.2.6/src/redis-cli --cluster create 172.19.80.33:7001 172.19.80.33:7002 172.19.80.33:7003 172.19.80.34:7004 172.19.80.34:7005 172.19.80.34:7006 --cluster-replicas 1
