环境

centos 7.5 192.168.253.110 资源包：https://download.csdn.net/download/yeyslspi59/12888631

安装Docker、Docker-compose及配置加速

1）配置阿里的docker源

[root@redis-master ~]# wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo

2）安装docker、docker-compose

[root@redis-master ~]# yum -y install docker docker-compose
[root@redis-master ~]# vim /etc/docker/daemon.json   #配置加速
{"registry-mirrors": ["https://26ahzfln.mirror.aliyuncs.com"]}

3）启动docker、关闭防火墙

[root@redis-master ~]# systemctl  stop firewalld    ##做集群我们需要关闭防火墙，否则后面会出现错误
[root@redis-master ~]# setenforce 0
[root@redis-master ~]# systemctl  start docker

准备工作

1）上传redis包并解压

[root@redis-master ~]# mkdir redis-cluster
[root@redis-master redis-cluster]# ls
redis-5.0.9  redis-5.0.9.tar.gz        #最好是转换成tar.gz，我的资源下载获取的是zip格式

2）编写.yaml文件

[root@redis-master redis-cluster]# vim docker-compose.yml
version: '3'

services:
 redis1:
  image: publicisworldwide/redis-cluster
  restart: always
  volumes:
   - /data/redis/8001/data:/data
  environment:
   - REDIS_PORT=8001
  ports:
    - '8001:8001'       #服务端口
    - '18001:18001'   #集群端口

 redis2:
  image: publicisworldwide/redis-cluster
  restart: always
  volumes:
   - /data/redis/8002/data:/data
  environment:
   - REDIS_PORT=8002
  ports:
    - '8002:8002'
    - '18002:18002'

 redis3:
  image: publicisworldwide/redis-cluster
  restart: always
  volumes:
   - /data/redis/8003/data:/data
  environment:
   - REDIS_PORT=8003
  ports:
    - '8003:8003'
    - '18003:18003'

 redis4:
  image: publicisworldwide/redis-cluster
  restart: always
  volumes:
   - /data/redis/8004/data:/data
  environment:
   - REDIS_PORT=8004
  ports:
    - '8004:8004'
    - '18004:18004'

 redis5:
  image: publicisworldwide/redis-cluster
  restart: always
  volumes:
   - /data/redis/8005/data:/data
  environment:
   - REDIS_PORT=8005
  ports:
    - '8005:8005'
    - '18005:18005'

 redis6:
  image: publicisworldwide/redis-cluster
  restart: always
  volumes:
   - /data/redis/8006/data:/data
  environment:
   - REDIS_PORT=8006
  ports:
    - '8006:8006'
    - '18006:18006'

3）启动编写好的.yaml文件并查看

[root@redis-master redis-cluster]# docker-compose up -d

Creating rediscluster_redis2_1 ... done
Creating rediscluster_redis3_1 ... done

运行容器并映射集群ip及端口

1）运行

2）查看是否成功

[root@redis-master redis-cluster]# docker ps   #up状态就是成功
CONTAINER ID        IMAGE                             COMMAND                  CREATED             STATUS              PORTS                                                                  NAMES

测试

1）设置值

[root@redis-master redis-cluster]# ./redis-5.0.9/src/redis-cli -c -p 8001
127.0.0.1:8001> set hya 11
-> Redirected to slot [15500] located at 172.18.0.1:8003
OK
172.18.0.1:8003> get hya
"11"
##在8001端口设置

2）指定端口获取值

[root@redis-master redis-cluster]# ./redis-5.0.9/src/redis-cli -c -p 8003
127.0.0.1:8003> get hya
"11"
###其他端口能获取到值 表示集群成功

3）其他端口获取值

[root@redis-master redis-cluster]# ./redis-5.0.9/src/redis-cli -c -p 8006
127.0.0.1:8006> get hya
-> Redirected to slot [15500] located at 172.18.0.1:8003
"11"
####奥利给 可以的
