Docker安装

1.  yum install -y yum-utils device-mapper-persistent-data lvm2
2.  yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
3.  yum clean all
4.  yum makecache fast
5.  yum -y install docker-ce
6.  systemctl start docker
7.  docker version

Redis安装

1.  mkdir /docer/redis\_docker
2.  mkdir /usr/local/redis\_docker
3.  cd /usr/local/redis\_docker/
4.  wget http://download.redis.io/releases/redis-4.0.1.tar.gz
5.  tar -xzf redis-4.0.1.tar.gz
6.  yum install -y gcc-c++
7.  cd redis-4.0.1/
8.  make
9.  vim redis.conf

bind 0.0.0.0
    requirepass yourpwd
    masterauth  yourpwd
    logfile  "/usr/local/redis/logs/redis-server.log"
    cluster-enabled yes
    cluster-config-file nodes-6379.conf
    cluster-node-timeout 15000

1.  cd …
2.  vim Dockerfile

#指定镜像
    FROM centos:7
    
    #定义路径的环境变量
    ENV REDIS_HOME /usr/local
    
    #将Dockerfile同级目录下的redis-4.0.1.tar.gz复制到镜像的根目录
    ADD redis-4.0.1.tar.gz /
    
    #创建安装目录，根据环境变量信息，实际的创建目录为:/usr/local/redis
    RUN mkdir -p $REDIS_HOME/redis
    
    #将Dockerfile同级目录下redis-4.0.1中的redis配置文件拷贝到容器的/usr/local/redis目录中
    ADD redis-4.0.1/redis.conf $REDIS_HOME/redis/
    
    #更新镜像的yum
    RUN yum -y update
    
    #安装gcc相关编译工具
    RUN yum install -y gcc make
    
    #指定工作目录
    WORKDIR /redis-4.0.1
    
    #执行编译
    RUN make
    
    #移动编译后的redis-server到容器相关的目录
    RUN mv /redis-4.0.1/src/redis-server  $REDIS_HOME/redis/
    
    #移动到上一级
    WORKDIR /
    
    #删除解压文件
    RUN rm -rf /redis-4.0.1
    
    #删除对于的工具
    RUN yum remove -y gcc make
    
    #添加数据卷
    #/usr/local/redis/logs/redis-server.log
    #此目录需要和redis.conf中logfile一致
    VOLUME ["/usr/local/redis/logs"]
    
    #暴露6379的端口
    EXPOSE 6379

1.  docker build -t myDocker/redis-cluster .
2.  mkdir /usr/local/redis\_docker/redis-node
3.  cd /usr/local/redis\_docker/redis-node
4.  vim Dockerfile

FROM myDocker/redis-cluster:latest
    
    ENTRYPOINT ["/usr/local/redis/redis-server", "/usr/local/redis/redis.conf"]

1.  docker build -t myDocker/redis-node .
2.  docker run -d --name redis-node-7000 -p 7000:6379 myDocker/redis-node
3.  docker run -d --name redis-node-7001 -p 7001:6379 myDocker/redis-node
4.  docker run -d --name redis-node-7002 -p 7002:6379 myDocker/redis-node
5.  docker run -d --name redis-node-7003 -p 7003:6379 myDocker/redis-node
6.  docker run -d --name redis-node-7004 -p 7004:6379 myDocker/redis-node
7.  docker run -d --name redis-node-7005 -p 7005:6379 myDocker/redis-node
8.  docker ps
9.  docker inspect **7000-7005的docker容器id,通过docker ps命令可以看到** |grep IPAddress
10. ls -l redis-cli
11. cp redis-cli /usr/local/bin
12. redis-cli -p 7000
13. redis-cli -p 7000 -a **你设置的密码**

集群配置

1.  vim addslots.sh

#将0-5461的槽点配置在172.17.0.4:6379（宿主机127.0.0.1:7000）的redis上
    n=0
    for ((i=n;i<=5461;i++))
    do
       /usr/local/bin/redis-cli -h 127.0.0.1 -p 7000 -a chhu2017  CLUSTER ADDSLOTS $i
    done
    
    #将5462-10922的槽点配置在172.17.0.5:6379（宿主机127.0.0.1:7001）的redis上
    n=5462
    for ((i=n;i<=10922;i++))
    do
       /usr/local/bin/redis-cli -h 127.0.0.1 -p 7001 -a chhu2017  CLUSTER ADDSLOTS $i
    done
    
    #将10923-16383的槽点配置在172.17.0.6:6379（宿主机127.0.0.1:7002）的redis上
    n=10923
    for ((i=n;i<=16383;i++))
    do
       /usr/local/bin/redis-cli -h 127.0.0.1 -p 7002 -a chhu2017  CLUSTER ADDSLOTS $i
    done

1.  sh addslots.sh
2.  vi addSlaveNodes.sh

/usr/local/bin/redis-cli -h 127.0.0.1 -p 7002 -a chhu2017 CLUSTER REPLICATE 172.17.0.6:6379的集群ID
    
    /usr/local/bin/redis-cli -h 127.0.0.1 -p 7003 -a chhu2017 CLUSTER REPLICATE 172.17.0.5:6379的集群ID
    
    /usr/local/bin/redis-cli -h 127.0.0.1 -p 7004 -a chhu2017 CLUSTER REPLICATE 172.17.0.7:6379的集群ID

1.  sh addSlaveNodes.sh
