Please check openssl library versions. 1.需要修改每个机器上的ambari-agent.ini文件，需要在security下面添加一行： 编辑文件：vi /etc/ambari-agent/conf/ambari-agent.ini force_https_protocol = PROTOCOL_TLSv1_2 2.看着是openssl问题 但实际上应该是python版本原因 因为python2.7.5以上的版本增加了版本验证 需要降低python版本或者关闭证书验证： vi /etc/python/cert-verification.cfg [https] verify=disable 如果python版本低于2.7.5，请尝试更新openssl
