Datax MySQL读：   /tupian/20230522/DataX/blob/master/mysqlreader/doc/mysqlreader.md

Datax MySQL写：   /tupian/20230522/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]#
