(1) 主数据库创建一个数据库
mysql> create database abc;
Query OK, 1 row affected (0.02 sec)
mysql> show master status\G;

(2) 从数据库查看同步情况
mysql> show databases;

二、 配置Mysql5.6 GTID主从 （主从异步模式转成GTID模式）方式二
mysql-5.6主从同步配置示例 http://koumm.blog.51cto.com/703525/1764093
原环境本身已经是异步主从同步模式。
1，从主库添加如上GTID相关配置文件，重启数据库后，主库锁表，备份数据库。
mysql> flush tables with read lock;
2，从库操重新配置从库，清除掉原来的主库配置信息, 或者采用导入数据库。
mysql> stop slave;
mysql> reset slave;
3，在保证数据同步的情况下从库重新连接主库同步。
mysql>
CHANGE MASTER TO
MASTER_HOST=‘192.168.0.65‘,
MASTER_PORT=3306,
MASTER_USER=‘repl‘,
MASTER_PASSWORD=‘123456‘,
MASTER_AUTO_POSITION=1;
4，主库
mysql> unlock tables;
5，从库启动并测试同步情况
三、小结
可以在GTID的基础上配置半自动同步复制,可以查看相关文档，实际环境中需要对GTID相当了解后再用于生产环境。
