python连接redis：
import redis r = redis.Redis(host=‘192.168.50.181‘,port=6002) r.set(‘user_phone_14900000001‘,‘888888‘) r.get(‘user_phone_14900000001‘)
上面代码如果只执行一条数据是正常的，如果要用for循环批量更改数据连接redis集群，会报错redis.exceptions.ResponseError()
解决方案如下：
python连接redis集群：
from rediscluster import StrictRedisCluster list = [ ‘14900000001‘, ‘14900000002‘, ‘14900000003‘, ‘14900000004‘, ‘14900000005‘, ‘14900000006‘, ‘14900000007‘, ‘14900000008‘, ‘14900000009‘, ‘14900000010‘ ] def redis_cluster(list): redis_nodes = [ {‘host‘:‘192.168.50.39‘,‘port‘:6002}, {‘host‘:‘192.168.50.181‘,‘port‘: 6002}, ] try: redisconn = StrictRedisCluster(startup_nodes=redis_nodes) except: print(‘error‘) for i in range(0,len(list)): redisconn.set(‘user_phone_‘+list[i],‘888888‘) print(redisconn.get(‘user_phone_‘+list[i])) redis_cluster(list)
打印结果如下：
b‘888888‘
b‘888888‘
b‘888888‘
b‘888888‘
b‘888888‘
b‘888888‘
b‘888888‘
b‘888888‘
b‘888888‘
b‘888888‘
def redis_cluster(): redis_nodes = [ {‘host‘:‘192.168.50.39‘,‘port‘:6002}, {‘host‘:‘192.168.50.181‘,‘port‘: 6002}, ] try: redisconn = StrictRedisCluster(startup_nodes=redis_nodes) except: print(‘error‘) for i in range(14900000011,14900000021): redisconn.set(‘user_phone_‘+str(i),‘888888‘) print(redisconn.get(‘user_phone_‘+str(i))) redis_cluster()
