oracle goldengate for MySQL DDL试验

1.创建MySQL的连接：
# ln -s /var/lib/mysql/mysql.sock /tmp/mysql.sock

到ogg的目录安装插件：
#cd /usr/local/ogg_mysql

# ./ddl_install.sh install root oracle 3306  
5.7.25-log
checking MySQL version
DDL is supported for your installed MySQL version.
plugin_dir: /usr/lib64/mysql/plugin/

The metadata_server could not be started. See ddlmetadataserver.log for details.
[root@node2 ogg_mysql]# nohup: appending output to ‘nohup.out’

注释：root为用户名，oracle为密码，3306为MySQL实例的端口。

-- metadata server启动、关闭、重启操作：
#./ddl_install.sh start root yijiupi 3306 
stop 关闭
restart 重启
# ./ddl_install.sh stop root oracle 3306         
The metadata_server has stopped.

-- metadata server 的进程查看：
# ps -ef | grep -i metadata
root      23907      1  0 19:08 pts/0    00:00:00 ./metadata_server root xxxxxx 3306

2.编辑参数：

PURGEOLDEXTRACTS ./dirdat/*,usecheckpoints, minkeepdays 3

Query OK, 0 rows affected (0.06 sec)

mysql> flush privileges;
Query OK, 0 rows affected (0.01 sec)
