ambari2.7.5集成es6.4.2

参考

ambari2.7.1+hdp3.0.1集成Elasticsearch6.4.2_再看我把你吃掉的博客-CSDN博客

本次只验证安装单节点的es与slave

1.将Ambari-Elastic-Service-master放到/opt/es后解压

2.ELASTICSEARCH-6.4.x文件夹和KIBANA-6.4.x文件夹拷贝到/var/lib/ambari-server/resources/stacks/HDP/3.1/services目录，并修改名文件名

 3.将包放到此目录下，这里需要安装http，没有安装可自行安装

包放好后，一定需要修改权限，正常为644

4.重启ambari-server

ambari-server restart

5. 重启完过后页面添加es

 下一步，选择安装节点，

Elasticsearch Download Url 这里就是第三步中的位置

6.安装Master报错

  File "/usr/lib/ambari-agent/lib/resource_management/core/shell.py", line 314, in _call

    raise ExecutionFailed(err_msg, code, out, err)

resource_management.core.exceptions.ExecutionFailed: Execution of '

cd /opt/elasticsearch/master; wget http:hadoop06/es/elasticsearch-6.4.2.tar.gz -O elasticsearch.tar.gz -a /var/log/elasticsearch/master/elasticsearch-install.log' returned 4.

 stdout:

排查发现是由于 Jar包的权限导致，改成644后，Master安装成功

7.Master启动失败

stderr: 
Traceback (most recent call last):
  File "/var/lib/ambari-agent/cache/stacks/HDP/3.1/services/ELASTICSEARCH/package/scripts/es_master.py", line 168, in <module>
    ESMaster().execute()
  File "/usr/lib/ambari-agent/lib/resource_management/libraries/script/script.py", line 352, in execute

--------

File"/var/lib/ambari-agent/cache/stacks/HDP/3.1/services/ELASTICSEARCH/package/templates/elasticsearch.master.yml.j2", line 93, in top-level template code

  File "/usr/lib/ambari-agent/lib/resource_management/libraries/script/config_dictionary.py", line 73, in __getattr__
    raise Fail("Configuration parameter '" + self.name + "' was not found in configurations dictionary!")
resource_management.core.exceptions.Fail: Configuration parameter 'hostname' was not found in configurations dictionary!

这里报错一直找不到hostname

解决方法

这里进入这个脚本路径打开这个脚本

/var/lib/ambari-agent/cache/stacks/HDP/3.1/services/ELASTICSEARCH/package/scripts/params.py

 发现hostname没有指定具体的配置路径

尝试将具体路径加上如下所示，在elasticsearch-config中添加上hostname

hostname = config['configurations']['elasticsearch-config']['hostname']

再将elasticsearch-config.xml中添加上hostname参数，如下

/var/lib/ambari-server/resources/stacks/HDP/3.1/services/ELASTICSEARCH/configuration/elasticsearch-config.xml

<!-- hostname -->
    <property>
        <name>hostname</name>
        <value>hadoop06</value>
        <display-name>hostname</display-name>
    </property>
 

操作完成重启ambari-server 然后将服务删除掉再重新安装

安装时可以查到此参数 

9.服务安装成功，但是启动失败

通过查看日志/var/log/elasticsearch/master/my_es_cluster.log 报错如下

[2] bootstrap checks failed
[1]: max file descriptors [65535] for elasticsearch process is too low, increase to at least [65536]
[2]: max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144]

这个报错在Master节点按以下方法解决

解决：max file descriptors [65535] for elasticsearch process is too low_春风化作秋雨的博客-CSDN博客

到目前为止，es服务启动成功
