### Dolphin Scheduler的Ambari插件使用说明

##### 备注

1. 本文档适用于对Ambari中基本了解的用户
2. 本文档是对已安装Ambari服务添加Dolphin Scheduler(1.3.0版本)服务的说明

##### 一  安装准备

1. 准备RPM包

   - 在源码dolphinscheduler-dist目录下执行命令```mvn -U clean install rpm:attached-rpm  -Prpmbuild  -Dmaven.test.skip=true -X```即可生成(在目录 dolphinscheduler-dist/target/rpm/apache-dolphinscheduler-incubating/RPMS/noarch 下)

2. 创建DS的安装用户--权限

3. 初始化数据库信息

   ```
   -- 创建Dolphin Scheduler的数据库：dolphinscheduler
   CREATE DATABASE dolphinscheduler DEFAULT CHARACTER SET utf8 DEFAULT COLLATE
   utf8_general_ci;
   
   -- 初始化dolphinscheduler数据库的用户和密码，并分配权限
   -- 替换下面sql语句中的{user}为dolphinscheduler数据库的用户
   GRANT ALL PRIVILEGES ON dolphinscheduler.* TO '{user}'@'%' IDENTIFIED BY '{password}';
   GRANT ALL PRIVILEGES ON dolphinscheduler.* TO '{user}'@'localhost' IDENTIFIED BY
   '{password}';
   flush privileges;
   ```
