DataX案例：从Oracle中读取数据存到MySQL
从Oracle中读取数据存到MySQL
1）MySQL中创建表
[oracle@hadoop102 ~]$ mysql -uroot -p000000 mysql> create database oracle; mysql> use oracle; mysql> create table student(id int,name varchar(20));
2）编写datax配置文件
[oracle@hadoop102 ~]$ vim /opt/module/datax/job/oracle2mysql.json { "job": { "content": [ { "reader": { "name": "oraclereader", "parameter": { "column": ["*"], "connection": [ { "jdbcUrl": ["jdbc:oracle:thin:@hadoop102:1521:orcl"], "table": ["student"] } ], "password": "000000", "username": "jason" } }, "writer": { "name": "mysqlwriter", "parameter": { "column": ["*"], "connection": [ { "jdbcUrl": "jdbc:mysql://hadoop102:3306/oracle", "table": ["student"] } ], "password": "000000", "username": "root", "writeMode": "insert" } } } ], "setting": { "speed": { "channel": "1" } } } }
3）执行命令
[oracle@hadoop102 ~]$ /opt/module/datax/bin/datax.py /opt/module/datax/job/oracle2mysql.json
查看结果:
mysql> select * from student; +------+----------+ | id | name | +------+----------+ | 1 | zhangsan | +------+----------+
