数据是复制过来的，MySQL主从复制是正常的，那么我们为了验证MySQL复制SQL线程是居于刚才那张图的流程，有主键，就按主键更新匹配更新记录。
那么我们在从库修改一行数据，故意制造不一致。
(dg7)root@localhost [mytest]> UPDATE `table_pk` SET `name`= ‘ laowang ‘ WHERE ` id `= 333； Query OK, 0 rows affected ( 0.00 sec) Rows matched: 1 Changed: 0 Warnings: 0 (dg7)root@localhost [mytest] > select * from table_pk; +-----+-----------+-----+-----+ | id | name | age | sex | +-----+-----------+-----+-----+ | 111 | zhangsan | 20 | 0 | | 222 | lisi | 22 | 1 | | 333 | laowang | 22 | 1 | | 444 | lilei | 32 | 0 | | 555 | hanmeimei | 30 | 1 | +-----+-----------+-----+-----+ 5 rows in set ( 0.00 sec)
这时候主从数据不一致了
主库 (dg6)root@localhost [mytest] > select * from table_pk where id = 333 ; +-----+--------+-----+-----+ | id | name | age | sex | +-----+--------+-----+-----+ | 333 | wangwu | 22 | 1 | +-----+--------+-----+-----+ 1 row in set ( 0.00 sec) 从库 (dg7)root@localhost [mytest] > select * from table_pk where id = 333 ; +-----+---------+-----+-----+ | id | name | age | sex | +-----+---------+-----+-----+ | 333 | laowang | 22 | 1 | +-----+---------+-----+-----+ 1 row in set ( 0.00 sec) (dg7)root@localhost [mytest] >
那么，我们在主库更新一行数据。
(dg6)root@localhost [mytest]> UPDATE `table_pk` SET `name`= ‘ wangzi ‘ WHERE ` id `= 333 ; Query OK, 1 row affected ( 0.01 sec) Rows matched: 1 Changed: 1 Warnings: 0 (dg6)root@localhost [mytest] > select * from table_pk where id = 333 ; +-----+--------+-----+-----+ | id | name | age | sex | +-----+--------+-----+-----+ | 333 | wangzi | 22 | 1 | +-----+--------+-----+-----+ 1 row in set ( 0.00 sec)
我们来看一下从库状态，是不是主库的更新给复制过来了，见证奇迹的时候到了

3.验证没有索引的情况
主库创建表和插入记录
CREATE TABLE `table_index` ( ` id ` int ( 11 ) NOT NULL, `name` varchar( 20 ) NOT NULL, `age` tinyint( 4 ) NOT NULL, `sex` tinyint( 4 ) NOT NULL COMMENT ‘ 0,man,1,woman ‘ , ) ENGINE = InnoDB (dg6)root@localhost [mytest] > select * from table_index; +-----+-----------+-----+-----+ | id | name | age | sex | +-----+-----------+-----+-----+ | 111 | zhangsan | 20 | 0 | | 222 | lisi | 22 | 1 | | 333 | wangwu | 22 | 1 | | 444 | lilei | 32 | 0 | | 555 | hanmeimei | 30 | 1 | +-----+-----------+-----+-----+ 5 rows in set ( 0.00 sec) (dg6)root@localhost [mytest] >
从库看看
(dg7)root@localhost [mytest]> select * from table_index; +-----+-----------+-----+-----+ | id | name | age | sex | +-----+-----------+-----+-----+ | 111 | zhangsan | 20 | 0 | | 222 | lisi | 22 | 1 | | 333 | wangwu | 22 | 1 | | 444 | lilei | 32 | 0 | | 555 | hanmeimei | 30 | 1 | +-----+-----------+-----+-----+ 5 rows in set ( 0.00 sec)
我们在从库继续搞破坏，把age为22的记录修改为laowang，这时候主从已经不一致了。
(dg7)root@localhost [mytest]> select * from table_index where age= ‘ 22 ‘ ; +-----+--------+-----+-----+ | id | name | age | sex | +-----+--------+-----+-----+ | 333 | wangwu | 22 | 1 | +-----+--------+-----+-----+ 1 row in set ( 0.00 sec) (dg7)root@localhost [mytest] > update table_index set name= ‘ laowang ‘ where age= 22 ; Query OK, 1 row affected ( 0.01 sec) Rows matched: 1 Changed: 1 Warnings: 0 (dg7)root@localhost [mytest] > select * from table_index where age= 22 ; +-----+---------+-----+-----+ | id | name | age | sex | +-----+---------+-----+-----+ | 333 | laowang | 22 | 1 | +-----+---------+-----+-----+ 1 row in set ( 0.00 sec) (dg7)root@localhost [mytest] >
那么我们还是在主库更新一下记录。
(dg6)root@localhost [mytest]> select * from table_index where name= ‘ lisi ‘ ; +-----+------+-----+-----+ | id | name | age | sex | +-----+------+-----+-----+ | 222 | lisi | 22 | 1 | +-----+------+-----+-----+ 1 row in set ( 0.00 sec) (dg6)root@localhost [mytest] > update table_index set age= 30 where name= ‘ lisi ‘ ; Query OK, 1 row affected ( 0.01 sec) Rows matched: 1 Changed: 1 Warnings: 0 (dg6)root@localhost [mytest] > select * from table_index where name= ‘ lisi ‘ ; +-----+------+-----+-----+ | id | name | age | sex | +-----+------+-----+-----+ | 222 | lisi | 30 | 1 | +-----+------+-----+-----+ 1 row in set ( 0.00 sec) (dg6)root@localhost [mytest] >
回到从库看看，数据没有更新过来，主从复制也是异常的
(dg7)root@localhost [mytest]> select * from table_index where name= ‘ lisi ‘ ;
+-----+------+-----+-----+
| id | name | age | sex |
+-----+------+-----+-----+
| 222 | lisi | 33 | 1 |
