MySQL 主从同步架构中你不知道的“坑”（2）

指定同步库情况

1、binlog_format= ROW模式‍

mysql> use testdb;

Database changed

mysql> show tables;

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

| Tables_in_testdb |

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

| test01      |

| test1      |

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

3 rows in set (0.00 sec)

mysql> insert into test1 values('zhng','man');

Query OK, 1 row affected (0.05 sec)

mysql> insert into test1 values('meimei','woman');

Query OK, 1 row affected (0.04 sec)

mysql> select * from test1;

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

| id  | name  |

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

| zhang | man  |

| zhng | man   |

| meimei | woman |

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

3 rows in set (0.00 sec)

从库查看

mysql> use testdb;

Database changed

mysql> show tables;

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

| Tables_in_testdb |

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

| test01      |

| test1      |

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

2 rows in set (0.01 sec)

mysql> select * from test1;

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

| id  | name  |

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

| zhang | man  |

| zhng | man  |

| meimei | woman |

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

3 rows in set (0.01 sec)

2、binlog_format= STATEMENT模式‍

主库配置如下

binlog-do-db = testdb

从库配置如下

replicate-wild-do-table = testdb.%

主库操作

mysql> create database testdb;

Query OK, 1 row affected (0.01 sec)

mysql> use testdb;

Database changed

mysql> create table test01 (

-> id varchar(10) not null,

-> name varchar(10) not null

-> );

Query OK, 0 rows affected (0.04 sec)

mysql> insert into test01 values('zhang','man');

Query OK, 1 row affected (0.01 sec)

mysql> select * from testdb.test01;

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

| id  | name |

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

| zhang | man  |

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

1 row in set (0.00 sec)

从库查看

mysql> use testdb;

Database changed

mysql> select * from test01;

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

| id  | name |

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

| zhang | man  |

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

1 row in set (0.00 sec)

测试在不指定忽略库的情况下默认库是否会同步数据

mysql> create user testdb_user;

Query OK, 0 rows affected (0.03 sec)

mysql> select user from mysql.user;

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

| user    |

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

| testdb_user |

| mysql.sys |

| root    |

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

[root@mysql-s ~]# mysql -uroot -p -e "select user from mysql.user;"

Enter password:

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

| user   |

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

| mysql.sys |

| root   |

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

注：默认的库的数据没有被同步
