ambari代理无法到达ambari服务器。

Question

当我在webUI上使用httpd本地存储库和Comfire主机安装ambari服务器时，我得到了如下错误：

INFO 2018-05-27 15:39:16,776 NetUtil.py:70 - Connecting to https://master:8440/ca

我的环境信息如下：

• CentOS Linux7.5.1804版(核心)
• Python2.7.5
• Java1.8.0_171
• OpenSSL1.0.2k
• Ambari2.6.2.0
• HDP-2.6.5.0

在我的其他amabri代理节点上，我可以在8440端口上到达master，如下所示：

[root@slave2 ~]# telnet master 8440
Trying 192.168.17.128...
Connected to master.
Escape character is '^]'.

请给我一些帮助，非常感谢！

Answer 1

我也得到了同样的问题。

这对我有用。

在/etc/ambari-agent/conf/ambari-agent.ini中

将这一行添加到[security]下面

force_https_protocol=PROTOCOL_TLSv1_2

在/etc/python/cert-verification.cfg中

[https]

verify=disable 

(从默认更改为禁用)

Answer 2

请在安装过程中检查JAVA_HOME和openSSL版本
