Quick Start

Quick Start

System Requirements

• Linux、Windows
• JDK(1.6以上，推荐1.6)
• Python(推荐Python2.6.X)
• Apache Maven 3.x (Compile DataX)

一、工具下载以及部署

• 方法一、直接下载DataX工具包(如果仅是使用，推荐直接下载)：DataX下载地址

  下载后解压至本地某个目录，进入bin目录，即可运行样例同步作业：

  $ tar zxvf datax.tar.gz
  $ cd  {YOUR_DATAX_HOME}/bin
  $ python datax.py ../job/job.json

• 方法二、下载DataX源码，自己编译：DataX源码编译方法

二、配置示例：从stream读取数据并打印到控制台

• 第一步、创建作业的配置文件（json格式）

  可以通过命令查看配置模板： python datax.py -r {YOUR_READER} -w {YOUR_WRITER}

  $ cd  {YOUR_DATAX_HOME}/bin
  $  python datax.py -r streamreader -w streamwriter

  Please save the following configuration as a json file and  use
       python {DATAX_HOME}/bin/datax.py {JSON_FILE_NAME}.json
  to run the job.
  
  {
      "job": {
          "content": [
              {
                  "reader": {
                      "name": "mysqlreader",
                      "parameter": {
                          "column": [],
                          "connection": [
                              {
                                  "jdbcUrl": [],
                                  "table": []
                              }
                          ],
                          "password": "",
                          "username": "",
                          "where": ""
                      }
                  },
                  "writer": {
                      "name": "odpswriter",
                      "parameter": {
                          "accessId": "",
                          "accessKey": "",
                          "column": [],
                          "odpsServer": "",
                          "partition": "",
                          "project": "",
                          "table": "",
                          "truncate": true
                      }
                  }
              }
          ],
          "setting": {
              "speed": {
                  "channel": ""
              }
          }
      }
  }   

• 第二步、根据配置文件模板填写相关选项

  命令打印里面包含对应reader、writer的文档地址，以及配置json样例，根据json样例填空完成配置即可。根据模板配置json文件(mysql2odps.json)如下：

  {
      "job": {
          "content": [
              {
                  "reader": {
                      "name": "mysqlreader",
                      "parameter": {
                          "username": "****",
                          "password": "****",
                          "column": ["id","age","name"],
                          "connection": [
                              {
                                  "table": [
                                      "test_table"
                                  ],
                                  "jdbcUrl": [
                                      "jdbc:mysql://127.0.0.1:3306/test"
                                  ]
                              }
                          ]
                      }
                  },
                  "writer": {
                      "name": "odpswriter",
                      "parameter": {
                          "accessId": "****",
                          "accessKey": "****",
                          "column": ["id","age","name"],
                          "odpsServer": "http://service.odps.aliyun.com/api",
                          "partition": "pt='datax_test'",
                          "project": "datax_opensource",
                          "table": "datax_opensource_test",
                          "truncate": true
                      }
                  }
              }
          ],
          "setting": {
              "speed": {
                  "channel": 1
              }
          }
      }
  }

  • 第三步：启动DataX

    $ cd {YOUR_DATAX_DIR_BIN}
    $ python datax.py ./mysql2odps.json 

    同步结束，显示日志如下：

    ...
