goldengate 12.3 实现mysql数据及DDL实时同步

以下环境在mysql 5.7上完成。
set mysql_home=mysql安装路径
set path=%mysql_home%in;%path%
首先要准备mysql的启动，可参考：http://silentwu.iteye.com/blog/2308722
由于需要使用OGG解析日志，所以需要在my.ini/my.cnf中设置如下参数

log-bin=u:/soft/mysql/5.7/mysql-5.7.19-winx64/logs/log-bin
binlog-ignore-db=oggddl
binlog_format=row

如果需要同步DDL，则需要在OGG安装目录下执行：
ddl_install.cmd/sh install root "root_password" 3306

重启mysql，使参数生效。

 

准备测试库表和用户

 

--源库
create database testdb charset utf8;
use testdb;
create table tb1(id int primary key, name varchar(50));

--目标库
create database tgtdb charset utf8;
use tgtdb;
create table tgtdb.tb1(id int primary key, name varchar(50));

 

--同步用户
create user 'ogg'@'%' identified by 'ogg';
GRANT ALL PRIVILEGES ON *.* TO 'ogg'@'%' IDENTIFIED BY 'ogg' WITH GRANT OPTION; 
FLUSH   PRIVILEGES;

以下配置在同一节点上完成，所以不需要传输进程。

抽取进程参数ex1.prm

extract ex1
sourcedb testdb@localhost, userid ogg, password ogg
TRANLOGOPTIONS ALTLOGDEST "u:\soft\mysql\5.7\mysql-5.7.19-winx64\logs\log-bin.index"
exttrail ./dirdat/ea
ddl include mapped
table testdb.*;

add extract ex1, tranlog, begin now
add exttrail ./dirdat/ea, extract ex1

 

投递进程参数re1.prm

replicat re1
targetdb tgtdb@localhost, userid ogg, password ogg
AssumeTargetDefs
map testdb.*, target tgtdb.*;

add replicat re1, exttrail ./dirdat/ea, nodbcheckpoint

-- DML测试
insert into testdb.tb1 values(1,'bbc');
insert into testdb.tb1 values(2,'bdsfbc');

 

- DDL 测试
create table testdb.tb2(id int primary key, name varchar(50));
alter table testdb.tb2 add age int;
insert into testdb.tb2 values(2, 'cdl',40);
