## 黄海的步骤:
|
|
|
|
|
|
1、用ESF直接迁移完整的表
|
|
|
|
|
|
2、用 修改小写.sql 脚本将SQL修改表名和字段名修改为小写
|
|
|
|
|
|
3、将 loader_table_list.txt 维护好，这个项目是60张表
|
|
|
|
|
|
4、
|
|
|
dsideal_db_8da._tmp_dbsync
|
|
|
dsideal_db_8da_temp.public
|
|
|
|
|
|
将两个库+架构下的所有临时表删除掉。
|
|
|
|
|
|
5、在Mysql库中执行
|
|
|
|
|
|
show master status;
|
|
|
|
|
|
记录下
|
|
|
|
|
|
binlogfile = "mysql-bin.001250"
|
|
|
binlogfile_offset = "715724074"
|
|
|
|
|
|
|
|
|
5、配置好my.cfg
|
|
|
|
|
|
binlogfile = "mysql-bin.001250"
|
|
|
binlogfile_offset = "715724074"
|
|
|
|
|
|
|
|
|
6、
|
|
|
#启动 binlog 拉取进程
|
|
|
nohup ./binlog_miner 1>minner.log 2>&1 &
|
|
|
|
|
|
#启动 binlog 写入进程
|
|
|
nohup ./binlog_loader 1>loader.log 2>&1 &
|
|
|
|

|
|
|
|
|
|
1.执行 ./mysql2pgsql -l loader_table_list.txt -d -n 生成创建PG格式数据表的SQL
|
|
|
|
|
|
2.Navicat Premium，创建一个查询，粘贴SQL，ctrl+a,ctrl+u转小写，修改<distribution key>为主键，执行，完成创建动作。
|
|
|
|
|
|
3../mysql2pgsql -l loader_table_list.txt 完成全量数据初始化
|
|
|
|
|
|
./mysql2pgsql -l huanghai.txt
