python3 连接redis集群

版本信息

• python版本 3.7
• pip install redis==3.5.3
• pip install redis-py-cluste==2.1.3

集群连接

1. 单节点连接
   通过集群里面的任意节点连接到集群，连接之后，客户端会向服务器发送cluster slots命令获取集群哈希槽的分布信息。

import random
import rediscluster
import string
 
cli = rediscluster.RedisCluster(host='192.168.7.41', port=8001, password="")
for i in range(1000):
    cli.set(''.join(random.sample(string.ascii_letters, 10)), i, ex=1200)
print(cli)
cli.close()

2. 连接池连接

import random
import threading
 
import rediscluster
from rediscluster import ClusterConnectionPool
import string, time
 
startup_nodes = [
    {"host": "192.168.7.41", "port": 8001},
]
pool = ClusterConnectionPool(startup_nodes=startup_nodes, password="", max_connections=10, max_connections_per_node=10)
cli = rediscluster.RedisCluster(connection_pool=pool)
 
 
def test():
    for i in range(100):
        cli.set(''.join(random.sample(string.ascii_letters, 10)), i, ex=1200)
 
 
ths = [threading.Thread(target=test) for n in range(10)]
for t in ths:
    t.start()
for t in ths:
    t.join()
