我的环境: 我有三台Ubuntu服务器。 一台服务器用作使用Nginx的负载均衡器。 其他两台服务器包含完全相同的项目(与Redis相同,其中一个框是主设备,另一个是从设备)。RedisClusterException尝试使用Celery写入时
我使用 的Python, Gunicorn, Django的, 芹菜, Redis的, 哨兵程序/应用
什么我做的项目: 我有接受URL一个GET请求,对请求做一些逻辑并保存到redis中。
def save(key, value):
conn = redis_cluster_connect()
print conn
conn.set(key, value)
conn.set('bar','foo')
这是工作的罚款时,我的连接是:
def redis_connect():
print 'redis connected'
return redis.Redis(host="xxx.xx.xxx.x", port=6380, db=1) # CHANGE TO THE REDIS PORT THAT IS ACTIVE
但是当我使用群连接:
def redis_cluster_connect():
startup_nodes = [{"host": "xxx.xx.xxx.x", "port": "6380"}]
rc = StrictRedisCluster(startup_nodes=startup_nodes, decode_responses=True)
return rc
的错误,我得到:

当我运行redis的-CLI,并设置在主(在服务器1)的变量i可以检索其上的从(在服务器2)
server 1:
xxx.xx.xxx.x:6380> set test 100
OK
server 2:
xxx.xx.xxx.x:6381> get test
"100"
当我尝试做集群槽在redis的客户机命令我得到了与上述相同的错误。
xxx.xx.xxx.x:6380> cluster slots
(error) ERR unknown command 'cluster'
有一点要考虑的是我的redis的配置文件不具有TCP套接字,当我试图使用TCP的Redis是行不通的。当我尝试运行redis时,它给了我一个错误。这被更改为默认Unixsocket自带默认redis.conf文件
来源:
tcp-backlog 511
要:
unixsocket /var/run/redis/redis.sock
unixsocketperm 700
非常感谢,主控与redis集群之间我感到困惑。感谢您的澄清! – Jahedh
