1. 1. 使用 mysqldump 将 mysql的表结构和数据同步到 OceanBase 的MySQL 租户中
      1. Mysql数据库导出

mysqldump -h127.0.0.1 -P3306 -uroot –p '' --single-transaction --hex-blob --routines --events --triggers --set-gtid-purged=OFF --databases teller >teller.sql

mysql> use tell;

mysql> show tables;

…………192 rows

1. 1. 1. oceanbase数据库导入

##使用之前的test租户登录,导入

obclient -h10.64.8.28 -P2883 -uroot@test#admin -p -A

source teller.sql;

obclient> show tables;

1. 1. datax 配置至少一个表的 MySQL 到 OceanBase 的 MySQL 租户的离线同步
      1. datax安装

wget http://datax-opensource.oss-cn-hangzhou.aliyuncs.com/datax.tar.gz

tar -xf datax.tar.gz -C /usr/local/

cd /usr/local/datax

yum install -y python2 java

##生成模板文件

python2 /usr/local/datax/bin/datax.py -r mysqlreader -w oceanbasev10writer > /usr/local/datax/job/my2ob.json

1. 1. 1. datax配置参数

##根据实际环境修改

vi /usr/local/datax/job/my2ob.json

                    }

                }

            }

        ]

    }

}

1. 1. 1. datax执行

python2 /usr/local/datax/bin/datax.py /usr/local/datax/job/my2ob.json
