一 拉取镜像

  1. docker pull redis:6.0.7

二 创建模板文件

  1. port ${PORT}
  2. protected-mode no
  3. cluster-enabled yes
  4. cluster-config-file nodes.conf
  5. cluster-node-timeout 5000
  6. #cluster-announce-ip 192.168.64.2
  7. #cluster-announce-port ${PORT}
  8. #cluster-announce-bus-port 1${PORT}
  9. bind 0.0.0.0
  10. appendonly yes
  11. logfile "redis.log"

三 生成配置文件

生成配置文件和文件夹

  1. cd  /Users/hezhaoming/Documents/docker/redis
  2. for port in `seq 7010 7015`; do \
  3.   mkdir -p ./${port}/conf \
  4.   && PORT=${port} envsubst < ./redis-cluster.tmpl > ./${port}/conf/redis.conf \
  5.   && mkdir -p ./${port}/data; \
  6. done

注意mac需要安装命令工具

  1. brew install gettext
  2. brew link --force gettext

四 编写编排文件

  1. version: '3'
  3. services:
  4.   redis1:
  5.     image: redis:6.0.7
  6.     hostname: redis1
  7.     container_name: redis1
  8.     networks:
  9.       redis-net:
  10.         ipv4_address: 172.35.0.10
  11.     restart: always
  12.     privileged: true
  13.     ports:
  14.       - 7010:7010
  15.       - 17010:17010
  16.     volumes:
  17.      - /Users/hezhaoming/Documents/docker/redis/7010/conf/redis.conf:/usr/local/etc/redis/redis.conf
  18.      - /Users/hezhaoming/Documents/docker/redis/7010/data:/data
  19.     command: redis-server /usr/local/etc/redis/redis.conf
  20.   redis2:
  21.     image: redis:6.0.7
  22.     hostname: redis2
  23.     container_name: redis2
  24.     networks:
  25.       redis-net:
  26.         ipv4_address: 172.35.0.20
  27.     restart: always
  28.     privileged: true

  37.     image: redis:6.0.7
  38.     hostname: redis3
  39.     container_name: redis3
  40.     networks:
  41.       redis-net:
  42.         ipv4_address: 172.35.0.30
  43.     restart: always
  44.     privileged: true
  45.     ports:
  46.       - 7012:7012
  47.       - 17012:17012
  48.     volumes:
  49.      - /Users/hezhaoming/Documents/docker/redis/7012/conf/redis.conf:/usr/local/etc/redis/redis.conf
  50.      - /Users/hezhaoming/Documents/docker/redis/7012/data:/data
  51.     command: redis-server /usr/local/etc/redis/redis.conf
  52.   redis4:
  53.     image: redis:6.0.7
  54.     hostname: redis4
  55.     container_name: redis4
  56.     networks:
  57.       redis-net:
  58.         ipv4_address: 172.35.0.40
  59.     restart: always
  60.     privileged: true
  61.     ports:
  62.       - 7013:7013
  63.       - 17013:17013
  64.     volumes:
  65.      - /Users/hezhaoming/Documents/docker/redis/7013/conf/redis.conf:/usr/local/etc/redis/redis.conf
  66.      - /Users/hezhaoming/Documents/docker/redis/7013/data:/data
  67.     command: redis-server /usr/local/etc/redis/redis.conf
  68.   redis5:
  69.     image: redis:6.0.7
  70.     hostname: redis5
  71.     container_name: redis5
  72.     networks:

  77.     ports:
  78.       - 7014:7014
  79.       - 17014:17014
  80.     volumes:
  81.       - /Users/hezhaoming/Documents/docker/redis/7014/conf/redis.conf:/usr/local/etc/redis/redis.conf

  83.     command: redis-server /usr/local/etc/redis/redis.conf
  84.   redis6:
  85.     image: redis:6.0.7
  86.     hostname: redis6
  87.     container_name: redis6

  96.     volumes:
  97.       - /Users/hezhaoming/Documents/docker/redis/7015/conf/redis.conf:/usr/local/etc/redis/redis.conf
  98.       - /Users/hezhaoming/Documents/docker/redis/7015/data:/data
  99.     command: redis-server /usr/local/etc/redis/redis.conf
  100. networks:
  101.   redis-net:
  102.     driver: bridge
  103.     ipam:
  104.       driver: default
  105.       config:
  106.         - subnet: 172.35.0.1/24

五 执行集群命令

  1. docker-compose up -d
  3. //随机进入一个节点 执行集群命令
  4. redis-cli --cluster create 172.35.0.10:7010  172.35.0.20:7011  172.35.0.30:7012  172.35.0.40:7013  172.35.0.50:7014  172.35.0.60:7015  --cluster-replicas 1
  5. // 交互提示是否创建，输入yes 回车
  6. //创建成功
  8. //随便进入一个节点 比如最后一个节点
  9. redis-cli -c -h 172.35.0.60 -p  7015 
  11. //输入命令,查看节点信息
  12. info 
  13. cluster nodes

六 测试使用
