ambari 添加自定义服务

1 告诉ambari添加什么服务

/var/lib/ambari-server/resources/stacks/HDP/2.5/services

目录下添加 服务名称 比如TEST

然后在目录下新建metainfo.xml 

cat /var/lib/ambari-server/resources/stacks/HDP/2.5/services/TEST/metainfo.xml

包括服务名称 版本号 加载资源的路径

       2.0

       

               

                       TEST

                       4.0

                       common-services/TEST/4.0

               

       

 

2 告诉ambari服务在哪怎么加载

在/var/lib/ambari-server/resources/common-services下

新建 TEST/4.0 要和上面对应起来

.
└── TEST
    └── 4.0
        ├── configuration
        │   └── test-env.xml
        ├── metainfo.xml
        └── package
            └── scripts
                ├── params.py
                └── test-ccc.py

目录结果如下 必须按照这个模板来 

gu里面的内容也必须按照这个模板来

 

configuation/test-env.xml   配置引用参数

注意全部的配置项对大小写以及下划线特别敏感，会无法执行

所以建议  小写 和_ 下划线
