安装配置部署HDP集群进行到confirm hosts时出现注册失败的解决方法

注意检查ambari-server和ambari-agent两个日志文件

 

直接参考 https://community.hortonworks.com/questions/121978/openssl-compatibility.html?childToView=138080#answer-138080

 

在部署集群时遇到Host checks were skipped on 4 hosts that failed to register.

 

进度条全部failed。

 

使用如下命令查看日志，并未发现有报错

 

cat /var/log/ambari-server/ambari-server.log

仅出现如下（摘自https://www.cnblogs.com/barneywill/p/10273687.html

我自己的log已被覆盖

 

并提示如下，说明集群并没有被创建。

 

INFO [pool-18-thread-1] AmbariMetricSinkImpl:95 - No clusters configured.

照着上面的博客对着metainfo.xml文件进行修改，将false改为true，重启ambari-server后，卡在了preparing阶段

 

/var/lib/ambari-server/resources/stacks/HDP/$version/metainfo.xml 

cat /var/lib/ambari-server/resources/stacks/HDP/2.6/metainfo.xml

 

<metainfo>

 

  <versions>

 

    <active>false</active>

 

  </versions>

 

  <extends>2.5</extends>

 

  <minJdk>1.7</minJdk>

 

  <maxJdk>1.8</maxJdk>

 

</metainfo>

查看日志后发现

 

28 三月 2019 14:16:53,750  INFO [Thread-36] BSRunner:372 - Error executing bootstrap Cannot create /var/run/ambari-server/bootstrap/1

28 三月 2019 14:16:53,750  WARN [Thread-36] BSRunner:401 - File does not exist: /var/run/ambari-server/bootstrap/1/sshKey

照着网上的方法手动创建相关文件和文件夹后，无果

 

//此时我已经创建了前4个文件夹

28 三月 2019 14:16:53,750  INFO [Thread-36] BSRunner:372 - Error executing bootstrap Cannot create /var/run/ambari-server/bootstrap/5

28 三月 2019 14:16:53,750  WARN [Thread-36] BSRunner:401 - File does not exist: /var/run/ambari-server/bootstrap/5/sshKey

索性重置了ambari-server，在看到https://www.oschina.net/question/2956577_2201031

 

这篇博客时，发现自己漏查了ambari-agent的日志，使用如下命令进入ambari-agent（与server在同一个文件夹下）

 

cat ambari-agent.log

 

//发现该报错

INFO 2019-03-28 15:46:41,820 NetUtil.py:70 - Connecting to https://hdpmaster:8440/ca

发现是因为centos7自带的python版本高于2.7.5，会诱发该ssl错误

 

解决方法：1.将机器自带的python版本降低于2.7.5

 

                  2.使用如下命令，在ambari-agent.ini的security底下添加和在.cfg的https底下添加（针对所有节点）

 

vi /etc/ambari-agent/conf/ambari-agent.ini

 

[security]

force_https_protocol=PROTOCOL_TLSv1_2

 

vi /etc/python/cert-verification.cfg 

 

[https] 

verify=disable

问题解决
