python 搭建redis集群

所需依赖

redis.io/download">redis-3.0.7
ruby-1.8.7：sudo apt-get install ruby
rubygems：sudo apt-get install rubygems
sudo gem install redis
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 6379
cluster-enabled yes
cluster-config-file nodes-6379.conf
cluster-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 StrictRedisCluster

startup_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 Python3
rc = StrictRedisCluster(startup_nodes=startup_nodes, decode_responses=True)

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

print rc.get("foo")
