mysql 中继日志_MySQL复制应用中继日志解析

SQL线程应用中继日志,在binlog_format是row格式的时候,是居于主键更新,下面结合一张图来证明

从一个大神那边得到一张图片,SQL线程应用中继日志流程,下面就实验验证一下:(PS,我个人认为这张图binlog_format为ROW格式是正确的)

2.验证有PK表情况

在主库创建表结构

CREATE TABLE `table_pk` (

`id`  int(11) NOT NULL ,

`name`  varchar(20) NOT NULL ,

`age`  tinyint NOT NULL ,

`sex`  tinyint NOT NULL COMMENT '0,man,1,woman' ,

PRIMARY KEY (`id`)

) ENGINE=InnoDB;

插入测试数据

insert into table_pk (`id`,`name`,`age`,`sex`) values(111,'zhangsan',20,0);

insert into table_pk (`id`,`name`,`age`,`sex`) values(222,'lisi',22,1);

insert into table_pk (`id`,`name`,`age`,`sex`) values(333,'wangwu',22,1);

insert into table_pk (`id`,`name`,`age`,`sex`) values(444,'lilei',32,0);

insert into table_pk (`id`,`name`,`age`,`sex`) values(555,'hanmeimei',30,1);

(dg6)root@localhost [(none)]> use mytest;

(dg6)root@localhost [mytest]> select * from table_pk;

+-----+-----------+-----+-----+

| id  | name      | age | sex |

+-----+-----------+-----+-----+

| 111 | zhangsan  |  20 |   0 |

| 222 | lisi      |  22 |   1 |

| 333 | wangwu    |  22 |   1 |

| 444 | lilei     |  32 |   0 |

| 555 | hanmeimei |  30 |   1 |

+-----+-----------+-----+-----+

rows in set (0.00 sec)

(dg6)root@localhost [mytest]> show global variables like '%binlog_format%';

+---------------+-------+

| Variable_name | Value |

+---------------+-------+

| binlog_format | ROW   |

+---------------+-------+

row in set (0.00 sec)

那么我们去从库看看

(dg7)root@localhost [mytest]> select * from table_pk;

+-----+-----------+-----+-----+

| id  | name      | age | sex |

+-----+-----------+-----+-----+

| 111 | zhangsan  |  20 |   0 |

| 222 | lisi      |  22 |   1 |

| 333 | wangwu    |  22 |   1 |

| 444 | lilei     |  32 |   0 |

| 555 | hanmeimei |  30 |   1 |

+-----+-----------+-----+-----+

rows in set (0.00 sec)

(dg7)root@localhost [mytest]> show global variables like '%binlog_format%';

+--------------------------+-------------------+

| Variable_name            | Value             |

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

| 555 | hanmeimei |  30 |   1 |

+-----+-----------+-----+-----+

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 |

+-----+--------+-----+-----+

从库

(dg7)root@localhost [mytest]> select * from table_pk where id=333;

+-----+---------+-----+-----+

| 333 | laowang |  22 |   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

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 |

+-----+-----------+-----+-----+

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 |

+-----+-----------+-----+-----+

rows in set (0.00 sec)

我们在从库继续搞破坏,把name为lisi的age修改为33,这时候主从已经不一致了。

(dg7)root@localhost [mytest]> select * from table_index where name='lisi';

+-----+------+-----+-----+

| id  | name | age | sex |

+-----+------+-----+-----+

| 222 | lisi |  22 |   1 |

+-----+------+-----+-----+

row in set (0.00 sec)

(dg7)root@localhost [mytest]> update table_index set age=33 where name='lisi';

Query OK, 1 row affected (0.01 sec)

Rows matched: 1  Changed: 1  Warnings: 0

(dg7)root@localhost [mytest]> select * from table_index where name='lisi';

+-----+---------+-----+-----+

| id  | name    | age | sex |

+-----+---------+-----+-----+

| 222 | lisi    |  33 |   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。把lisi的age修改成30,看看从库能不能更新过来

(dg6)root@localhost [mytest]> select * from table_index where name='lisi';

+-----+------+-----+-----+

| id  | name | age | sex |

+-----+------+-----+-----+

| 222 | lisi |  22 |   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 |

+-----+------+-----+-----+

row in set (0.00 sec)

(dg6)root@localhost [mytest]>

回到从库看看,数据没有更新过来,lisi的年龄还是33,这时候主从复制也是异常的,提示1032错误(找不到记录)

(dg7)root@localhost [mytest]> select * from table_index where name='lisi';

+-----+------+-----+-----+

| id  | name | age | sex |

+-----+------+-----+-----+

| 222 | lisi |  33 |   1 |

4.验证有唯一索引情况

测试方法都一样,下面步骤我都就贴结果了。(核心思想就是,从库先修改记录,做成主从数据不一致这种情况,然后主库再更新,看看从库有没有同步主库记录)
