# 部署方式：docker-compose #

*  以此镜像启动容器  
    ![image.png][]
 *  编写docker-compose文件  
    启动六个容器。三个主，三个从  
    `vi docker-compose.yml`

version: "3.2"
    services:
      redis-clu-m1:
        image: redis-ruby
        container_name: "redis-clu-m1"
        expose:
          - "6379"
        networks:
          - auto-cmdb_jumpserver-test
        tty: true
    
      redis-clu-m2:
        image: redis-ruby
        container_name: "redis-clu-m2"
        expose:
          - "6379"
        networks:
          - auto-cmdb_jumpserver-test
        tty: true
    
      redis-clu-m3:
        image: redis-ruby
        container_name: "redis-clu-m3"
        expose:
          - "6379"
        networks:
          - auto-cmdb_jumpserver-test
        tty: true
    
      redis-clu-s1:
        image: redis-ruby
        container_name: "redis-clu-s1"
        expose:
          - "6379"
        networks:
          - auto-cmdb_jumpserver-test
        tty: true
    
      redis-clu-s2:
        image: redis-ruby
        container_name: "redis-clu-s2"
        expose:
          - "6379"
        networks:
          - auto-cmdb_jumpserver-test
        tty: true
    
      redis-clu-s3:
        image: redis-ruby
        container_name: "redis-clu-s3"
        expose:
          - "6379"
        networks:
          - auto-cmdb_jumpserver-test
        tty: true
    networks:
      auto-cmdb_jumpserver-test:
        external:
            name: auto-cmdb_jumpserver-test

*  以之前自定义的此网络作为六个容器的网络  
    ![image.png][image.png 1]

![image.png][image.png 2]

*  下载redis-trib.rb文件  
    `vi /usr/sbin/redis-trib.rb`  
    `chmod 755 /usr/sbin/redis-trib.rb`  
    [https://github.com/antirez/redis/blob/3.2/src/redis-trib.rb][https_github.com_antirez_redis_blob_3.2_src_redis-trib.rb]
 *  拷贝文件

--------------------

`docker cp redis-clu-m1:/etc/redis-cluster.conf .`  
`docker cp redis-cluster.conf redis-clu-s3:/etc/`  
![image.png][image.png 3]

*  以配置文件启动服务  
    `docker-compose exec redis-clu-s3 redis-server /etc/redis-cluster.conf`  
    ![image.png][image.png 4]
 *  启动集群服务  
    `redis-trib.rb create --replicas 1 redis-clu-m1:6379 redis-clu-m2:6379 redis-clu-m3:6379 redis-clu-s1:6379 redis-clu-s2:6379 redis-clu-s3:6379`

> \*\*注意：\*\*如果容器名不能被解析，也可使用容器ip方式  
> `redis-trib.rb create --replicas 1 172.22.0.6:6379 172.22.0.7:6379 172.22.0.3:6379 172.22.0.2:6379 172.22.0.5:6379 172.22.0.4:6379`

![image.png][image.png 5]

*  六个容器对应的ip

172.22.0.6      redis-clu-m1
    172.22.0.7      redis-clu-m2
    172.22.0.3      redis-clu-m3
    172.22.0.2      redis-clu-s1
    172.22.0.5      redis-clu-s2
    172.22.0.4      redis-clu-s3

>  *  如果出现如下报错，可参考文章：  
>     [ERR Slot 741 is already busy (Redis::CommandError)][ERR Slot 741 is already busy _Redis_CommandError]

*  解决方案：  
    在`六个Redis集群`中，`flushall`清空各个节点上的数据，并执行`cluster reset`指令  
    ![清空节点数据][format_png]
 *  重启集群服务  
    `redis-trib.rb create --replicas 1 172.22.0.6:6379 172.22.0.7:6379 172.22.0.3:6379 172.22.0.2:6379 172.22.0.5:6379 172.22.0.4:6379`
