安装CDH 6.0.1遇到安装cm-agent的问题

Question

使用cloudera安装文档逐步操作我遇到了安装代理程序的麻烦 像这样：

表示安装失败，无法接收信号。 我发现这样的日志：

    [13/Nov/2018 16:44:19 +0000] 4306 MainThread agent        ERROR    Heartbeating to ryze-1.bigdata.com:7182 failed.
Traceback (most recent call last):
  File "/opt/cloudera/cm-agent/lib/python2.7/site-packages/cmf/agent.py", line 1371, in _send_heartbeat
    response = self.requestor.request('heartbeat', heartbeat_data)
  File "/opt/cloudera/cm-agent/lib/python2.7/site-packages/avro/ipc.py", line 141, in request
    return self.issue_request(call_request, message_name, request_datum)
  File "/opt/cloudera/cm-agent/lib/python2.7/site-packages/avro/ipc.py", line 254, in issue_request
    call_response = self.transceiver.transceive(call_request)
  File "/opt/cloudera/cm-agent/lib/python2.7/site-packages/avro/ipc.py", line 483, in transceive
    result = self.read_framed_message()
  File "/opt/cloudera/cm-agent/lib/python2.7/site-packages/avro/ipc.py", line 489, in read_framed_message
    framed_message = response_reader.read_framed_message()
  File "/opt/cloudera/cm-agent/lib/python2.7/site-packages/avro/ipc.py", line 417, in read_framed_message
    raise ConnectionClosedException("Reader read 0 bytes.")
ConnectionClosedException: Reader read 0 bytes.

我尝试用Google解决它，我已经检查了这些设置。

1. /etc/cloudera-scm-agent/config.ini端口集7182和server_host集ryze-1.bigdata.com。

2. 使用sudo service iptables stop

iptable已完全关闭

3. ryze-1.bigdata.com可以访问。并且telnet ryze-1.bigdata.com 7183可以成功。

操作系统：Centos7.4 平台：AliCloud

那我该怎么办？有人可以帮助我吗？
