需要安装的东西

redis-3.0.7
ruby-1.8.7：sudo apt-get install ruby
rubygems：sudo apt-get install rubygems
sudo gem install redis
# 其中我们如果执行时发现如下问题,请执行上述部分中gem install redis操作

redis-trib.rb:1573: warning: key "threshold" is duplicated and overwritten on line 1573
/usr/lib/ruby/2.3.0/rubygems/core_ext/kernel_require.rb:55:in `require': cannot load such file -- redis (LoadError)
from /usr/lib/ruby/2.3.0/rubygems/core_ext/kernel_require.rb:55:in `require'
from ./redis-trib.rb:25:in `<main>'

pip install redis-py-cluster

修改配置文件redis.conf

这里创建3个节点，所以复制3份redis.conf
分别命名为：redis-6379.conf, redis-6380.conf, redis-6381.conf
分别修改其中如下地方，拿redis-6379.conf来举例

port 6379cluster-enabled yescluster-config-file nodes-6379.confcluster-node-timeout 15000

开启3个redis-server节点

./redis-server ./redis-6379.conf
./redis-server ./redis-6380.conf
./redis-server ./redis-6381.conf

创建redis的集群

./redis-trib.rb create 127.0.0.1:6379 127.0.0.1:6380 127.0.0.1:6381

redis-py-cluster测试客户端

官网：https://github.com/Grokzen/redis-py-cluster

from rediscluster import StrictRedisClusterstartup_nodes = [{"host": "127.0.0.1", "port": "6379"}，                 {"host": "127.0.0.1", "port": "6380"},                 {"host": "127.0.0.1", "port": "6381"}                ]# Note: decode_responses must be set to True when used with python3rc = StrictRedisCluster(startup_nodes=startup_nodes, decode_responses=True)rc.set("foo", "bar")print rc.get("foo")
