Python 案例

#### 安装
>s pip3 install redis

#### 单机版示例
```
import redis

conn = redis.StrictRedis(connection_pool=redis.ConnectionPool(
			host="192.168.233.1", port="6379", password=""
		))

# string类型的写入读取
conn.set("key_name", "value")
conn.get("key_name")

# 列表类型的读取写入
conn.lpush("key_name", "value1", "value2",...)
conn.lrange("key_name", 0, -1) # 列出key_name下的所有值
```

#### 哨兵版示例
```
from redis.sentinel import Sentinel

sentinel_list = [
			("192.168.233.1", "26379"),
			("192.168.233.2", "26379"),
			("192.168.233.3", "26379")
		]
mySentinel = Sentinel(sentinel_list)
master = mySentinel.master_for("mymaster", db=0)
slave = mySentinel.slave_for("mymaster", db=0)

# 使用master进行写的操作，使用slave进行读的操作
master.hset("key_name", "filed", "value")
slave.hget("key_name", "filed")
slave.hgetall("key_name")
```

#### cluster 版示例
>s pip install redis-py-cluster
```
from rediscluster import StrictRedisCluster

cluster_nodes = [{"host": "192.168.233.1", "port": "9001"},
                 {"host": "192.168.233.1", "port": "9002"},
                 {"host": "192.168.233.1", "port": "9003"},
				]
conn = StrictRedisCluster(
			startup_nodes=cluster_nodes,
			decode_response=True,
			password="password",
			max_connection=300
		)

# 写入值，获取值
conn.set("key_name", "value")
conn.get("key_name")
```
