auth_provider = PlainTextAuthProvider(username='yyyy',password='zzzzz')
cluster = Cluster(['xx.xx.xx.xx'], control_connection_timeout=10, port=9042,auth_provider=auth_provider)
session = cluster.connect()
错误:
NoHostAvailable: ('Unable to connect to any servers', {'xx.xx.xx.xx:9042': ConnectionRefusedError(111, "Tried connecting to [('xx.xx.xx.xx ', 9042)]. Last error: Connection refused")})
我还在yaml文件中设置了rpc地址:0.0.0.0
