Datax离线数据抽取(MySQL--Oracle)

Datax下载地址：https://github.com/alibaba/DataX

Datax MySQL读： https://github.com/alibaba/DataX/blob/master/mysqlreader/doc/mysqlreader.md

Datax MySQL写： https://github.com/alibaba/DataX/blob/master/mysqlwriter/doc/mysqlwriter.md

1.下载安装Datax软件(必须安装jdk 1.8版本以上)

[root@localhost ~]# tar xvf jdk-8u65-linux-x64.tar.gz

[root@localhost ~]# mv jdk1.8.0_151 /usr/local/jdk1.8.0_151

[root@localhost ~]# vim /etc/profile

export PATH=$PATH:/usr/local/jdk1.8.0_151/bin

[root@localhost ~]# vim /etc/ld.so.conf.d/mysql-x86_64.conf

/usr/local/jdk1.8.0_151/lib

[root@localhost ~]# tar xvf datax.tar.gz

[root@localhost ~]# cd datax/job/

2.编辑配置文件(首先用kettle将表结构同步过去)

[root@localhost job]# vim job1.json

{    "job": {        "setting": {            "speed": {                "channel": 5            }        },        "content": [            {                "reader": {                    "name": "mysqlreader",                    "parameter": {                        "username": "wangying",                        "password": "wangying",                        "column": ["*"],                        "connection": [                           {                              "table": ["t3"],                              "jdbcUrl": ["jdbc:mysql://172.16.8.93:3306/db_stktag"]                           }                        ]                    }                },                "writer": {                    "name": "oraclewriter",                    "parameter": {                        "username": "upcenter",                        "password": "upcenter",                        "column": ["*"],                        "connection": [                            {                               "jdbcUrl": "jdbc:oracle:thin:@192.168.7.7:1521:upqc",                               "table": ["t3"]                            }                        ]                      }                    }                }        ]    }}

[root@localhost job]#

3.数据抽取

[root@localhost job]# python2 /root/datax/bin/datax.py job1.json
