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

 # 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")
