一、前言
如何将服务一劳永逸的集成到 ambari 中，方便新环境部署，无需二次拷贝呢？
通常，我们在自定义服务集成开发中，会将集成服务的代码项目放置到 /var/lib/ambari-server/resources/stacks/HDP/<version>/services/ 目录下。这样子的前提就是 ambari 与 hdp 集群必须提前搭建好。
其实这种方式是适合开发模式的。但是当集成服务开发、测试好之后，封版的话，再用这种方式就不太好了。假如有几十个自定义服务，你都得挨个手动拷贝，麻烦还容易犯错不是。并且万一要部署的环境再一多，显然这种并不是很好的部署模式。
那怎么办呢？
我们将集成服务的源码整合到 ambari-server rpm 包中不就行了？
我们需要将集成服务的源码放置在 ambari-server 模块的 resources 的对应目录下，然后再通过操作得到新的 ambari-server 的 rpm 即可。这里针对 rpm 包的制作提供了两种方式：
- 方式一：整体编译 ambari 源码（比较复杂，但是正规）
- 方式二：重新构建 rpm 包
二、方式一：整体编译 ambari 源码
以 ELASTICSEARCH 服务为例，将 ELASTICSEARCH 相关项目代码拷贝到 hdp 对应的 version 中，然后整体编译，得到新的 ambari-server rpm 包。
整体编译命令：
代码语言：javascript复制mvn -B -X -e install package rpm:rpm -DnewVersion=2.7.3.0.0 -DskipTests -Dpython.ver="python >= 2.6" -Drat.skip=true -Preplaceurl
详细可参考我的博客：《Ambari2.7.1整体编译 安装使用》 。
三、方式二：重新构建 rpm 包
如果嫌整体编译 ambari 太繁琐，也可以基于已有的 ambari-server rpm 包，重新构建 rpm 包，这样相对简单一些。
1、首先安装 rpmrebuild 工具
链接：https://pan.baidu.com/s/1SkO2SlLmrl4vWqbgrRuzHg 提取码：m1ti
将 tar 包拷贝到 /opt 下面，编译 rpmrebuild ，貌似 rpm 包与 rpmrebuild 版本有关系。
代码语言：javascript复制cd /opt
tar zxvf rpmrebuild-2.11.tar.gz
make
make install
2、安装工具 rpm-build
代码语言：javascript复制yum install rpm-build
3、安装 ambari-server
如果环境中没有 ambari-server 服务，可以先安装官方提供的 ambari-server 的 rpm 包
代码语言：javascript复制yum install ambari-server
4、将集成服务拷贝到指定目录
将自定义的集成服务拷贝到
/var/lib/ambari-server/resources/stacks/HDP/<version>/services/
目录下即可。
1）比如我要将 ELASTICSEARCH 集成到 hdp 3.1 里面，所以我需要将 ELASTICSEARCH 服务代码拷贝到 /var/lib/ambari-server/resources/stacks/HDP/3.1/services/ 目录下。
5、rebuild ambari-server 的 rpm 包
代码语言：javascript复制rpmrebuild -e ambari-server-2.7.3.0-139.x86_64
在执行 rpmrebuild -e 命令的交互过程中，可修改 .spec 文件，增加 ELASTICSEARCH 的相关文件：
代码语言：javascript复制%dir %attr(0755, root, root) "/var/lib/ambari-server/resources/stacks/HDP/3.1/services/ELASTICSEARCH"
%dir %attr(0755, root, root) "/var/lib/ambari-server/resources/stacks/HDP/3.1/services/ELASTICSEARCH/configuration"

大概需要 3、4 分钟，rpm 包就重新构建好了。
6、检查新构建的 rpm 包内是否有新添加的文件
代码语言：javascript复制rpm -qpl ambari-server-2.7.3.0-139.x86_64.rpm
7、安装新构建的 rpm 包
安装下新构建的 rpm 包，测试新集成的 ELASTICSEARCH 服务功能是否正常。
1）停止存在的 ambari-server 进程：ambari-server stop
2）卸载 ambari-server 服务：yum remove ambari-server
3) 安装新构建的 rpm 包：yum install /root/ambari-server-2.7.3.0-139.x86_64.rpm
4）重新设置 ambari-server 配置：ambari-server setup
5）启动 ambari-server 进程
6）重装 ELASTICSEARCH 服务，测试功能。
