1 row in set (0.00 sec)
2 在原主上添加：
vim /etc/my.cnf
添加：
replicate-do-db = xxx 要接收的库
# /etc/init.d/mysql restart
Shutting down MySQL... SUCCESS!

3 测试：
在原从上添加数据：
mysql> use students;
mysql> select * from users;
+----+------+
| id | name |
+----+------+
| 1 | a |
| 2 | b |
| 3 | c |
+----+------+
mysql> use students;
mysql> insert into users values (7,"g");
mysql> select * from users;
+----+------+
| id | name |
+----+------+
| 1 | a |
| 2 | b |
| 3 | c |
| 7 | g |
+----+------+
看原主
mysql> select * from users;
+----+------+
| id | name |
+----+------+
| 1 | a |
| 2 | b |
| 3 | c |
| 7 | g |
+----+------+
到此就实现了主主。
注意：
在mysql5.6之后不用指定以下，不然会出现报错：
