1.创建配置文件:

    /data/cluster目录下创建6个redis配置

2.逐个配置

    port  7001

    添加:

            daemonize yes

            cluster-enabled yes

            cluster-config-file redis-7001.conf

            cluster-node-timeout 5000

            appendonly yes #只读

3.依次启动redis实例

    redis-server /data/cluster/redis-7001.conf

4.获取分布式脚本 是ruby写的

    安装依赖 ruby>2.2.2版本

        yum install ruby rubygems -y

        gem sources --add https//gems.ruby-china.com/  #更换源

        升级

            gpg --keyserver hkp://keys.gnupg.net --recv-keys 409B6B1796C275462A1703113804BB82D39DC0E3

                curl -sSL https://get.rvm.io | bash -s stable

                source /usr/local/rvm/scripts/rvm

                rvm list known

                rvm install 2.5.1

                rvm use 2.5.1

                rvm remove 2.0.0

                ruby --version

            重新安装 gem install redis

拷贝redis-trib.rb到/data/cluster目录

运行ruby脚本

./redis-trib.rb reshared ip:port (你的IP地址)

8.python连接redis-cluster

    pip3 install redis-py-cluster

from rediscluster import strictRedisCluster

startup_nodes = [

    {"host": "127.0.0.1", "port": ""},

]

rc = StrictRedisCluster(startup_nodes=startup_nodes, decode_responses=True)

# 字符串操作

rc.set("foo", "bar")

print(rc.get("foo"))
