datax（1）：安装部署并且检测
一、datax实现功能
可以实现关系型数据库、阿里云数仓、nosql数据库、无结构化数据以及时间序列数据库之间的互相导入，如下图，功能十分强大，所以不觉想要研究一下
二、环境
1.Centos6.4
2.Datax
三、下载以及部署
1.下载
https://github.com/alibaba/DataX
点击下载
2.上传至服务器解压缩
tar -zxvf datax.tar.gz -C /opt/modules/3.检测datax安装成功与否
（1）进入datax根目录
/opt/modules/datax（2）运行测试job
python bin/datax.py job/job.json
结果：
DataX (DATAX-OPENSOURCE-3.0), From Alibaba !
