最近搞取数这一块，搞得有点头大，首先记录一下所用工具吧，调度工具用的azkaban（主要开源免费），取数工具用的kettle（也是开源免费），看到二个免费是不是有点慌，没关系，我所在的公司是个创业公司当然免费最好啦，哈哈，不过免费的也有他的好处（为公司考虑一下，嘿嘿）。
首先安装azkaban还是有点坑的，github上主要讲了步骤，但是有些坑还是需要注意一下：
编译源码
一、下载源码：
下载azkaban需要从git上获取：
- git clone https://github.com/azkaban/azkaban.git
java版本要求：1.8以上
二、编译：
# Build Azkaban
./gradlew build# Clean the build
./gradlew clean# Build and install distributions
./gradlew installDist# Run tests
./gradlew test# Build without running tests
./gradlew build -x test
这是GitHub上写的，我只是复制一下，不过这些步骤是必须一步一步执行的，才能正确编译；
不过也可以直接采用我的方式：cd azkaban; ./gradlew build installDist
编译时间很长，如果出现以下错误：JCE报错那么需要下载一点东西：

解决方法：下载JCEhttps://www.oracle.com/technetwork/cn/java/javase/downloads/jce8-download-2133166-zhs.html我这边使用的JDK8，包含了JCE所需要的jre8解压搜下载好的文件，放置到java的以下目录：
/usr/local/jdk1.8.0_74/jre/lib/security
覆盖后重新编译
采用默认数据库启动
采用单机版启动：
cd azkaban-solo-server/build/install/azkaban-solo-server; bin/start-solo.sh
启动后打开：http://localhost:8081/
页面如下，标识成功了，默认用户名和密码：azkaban和azkaban
后续加入mysql的配置，今天暂时到这里
