1、下载压缩包  
下载页面地址：https://github.com/alibaba/DataX  
不要在【Clone or download】处下载，那里下载的是源码；对于Java不是很在行的人来说，自行编译显得有点困难。  
而是在：【Quick Start】--->【Download DataX下载地址】进行下载。下载后的包名：datax.tar.gz。

2、环境依赖：

Centos7  
JDK(1.6以上，推荐1.6) = 参考文章：  
Python(推荐Python2.6.X) = 系统自动（python2.7）  
Apache Maven 3.x (Compile DataX) = 参考文章：

3、 运行DataX

tar -zxvf datax.tar.gz
    mv datax /usr/local/
    python /usr/local/datax/bin/datax.py /usr/local/datax/job/job.json

4、编辑(/usr/local/datax/job/job.json)文件

{
    	"job": {
    		"setting": {
    			"speed": {
    				"byte": 10485760
    			},
    			"errorLimit": {
    				"record": 0,
    				"percentage": 0.02
    			}
    		},
    		"content": [{
    			"reader": {
    				"name": "mysqlreader",
    				"parameter": {
    					"username": "admini",
    					"password": "123456",
    					"column": ["username", "passwd"],
    					"connection": [{

    						],
    						"jdbcUrl": [

    						]
    					}]
    				}
    			},
    			"writer": {
    				"name": "mysqlwriter",
    				"parameter": {
    					"username": "admini",
    					"password": "123456",

    						"passwd"
    					],
    					"connection": [{
    						"jdbcUrl": [
    							"jdbc:mysql://192.168.60.131:3306/datax"
    						],
    						"table": [
    							"user"
    						]
    					}]
    				}
    			}
    		}]
    	}
    }
