以下操作征对指定不同步库
1、binlog-format=ROW模式
查看主从的binlog模
- mysql> show slave statusG
- *********************** 1. row *************************
- Slave_IO_State: Waiting for master to send event
- Master_Host: 192.168.22.171
- Master_User: rep
- Master_Port: 3306
- Connect_Retry: 60
- Master_Log_File: master-bin.000004
- Read_Master_Log_Pos: 463
- Relay_Log_File: s1.000011
- Relay_Log_Pos: 630
- Relay_Master_Log_File: master-bin.000004
- Slave_IO_Running: Yes
- Slave_SQL_Running: Yes
- Replicate_Do_DB:
- Replicate_Ignore_DB: test
查看从库状态也显示此项配置
1:在忽略不同步的库不存在的情况下
在配置文件指定主从库都不存在的库,然后在主库中创建这个库,测试数据是否同步过去
主库创建数据库
- mysql> create database test;
- Query OK, 1 row affected (0.06 sec)
- mysql> show databases;
- +--------------------+
- | Database |
- +--------------------+
- | information_schema |
- | mysql |
- | performance_schema |
- | sys |
- | test |
- +--------------------+
- 5 rows in set (0.01 sec)
从库查看
- mysql> show databases;
- +--------------------+
- | Database |
- +--------------------+
- | information_schema |
- | mysql |
- | performance_schema |
- | sys |
- +--------------------+
- 5 rows in set (0.01 sec)
结论:发现建库的动作没有被从库同步过来
2:测试主从服务器库存在数据同步情况
目前主从库都存在库test001
- [root@mysql-m ~]# mysql -uroot -p -e "show databases;"|grep test001
- Enter password:
- test001
- [root@mysql-s ~]# mysql -uroot -p -e "show databases;"|grep test001
- Enter password:
- test001
在主库插入数据测试从库同步情况
- mysql> use test001;
- Database changed
- mysql> create table test (
- -> id varchar(10) not null,
- -> name varchar(10) not null
- -> );
- Query OK, 0 rows affected (0.06 sec)
- mysql> insert into test values('zhang','man');
- Query OK, 1 row affected (0.03 sec)
- mysql> select * from test;
- +-------+------+
- | id | name |
- +-------+------+
- | zhang | man |
- +-------+------+
- 1 row in set (0.00 sec)
- mysql> select * from test001.test;
- ERROR 1146 (42S02): Table 'test001.test' doesn't exist
- mysql> use test001;
- Database changed
- mysql> show tables;
- Empty set (0.00 sec)
结论:从库没有表,同样也有数据同步过来
3:征对数据库默认的库同步(如mysql)
- replicate-ignore-db = mysql
- #忽略指定不同步的库
测试前的数据
- [root@mysql-m ~]# mysql -uroot -p -e "select user,host from mysql.user;"
- Enter password:
- +-----------+--------------+
- | user | host |
- +-----------+--------------+
- | mysql.sys | localhost |
- | root | localhost |
- +-----------+--------------+
- [root@mysql-s ~]# mysql -uroot -p -e "select user,host from mysql.user;"
- Enter password:
- +-----------+--------------+
- | user | host |
- +-----------+--------------+
- | mysql.sys | localhost |
- | root | localhost |
- +-----------+--------------+
- [root@mysql-m ~]# mysql -uroot -p -e "grant all privileges on *.* to test@localhost identified by '123456';"
- Enter password:
- [root@mysql-m ~]# mysql -uroot -p -e "select user,host from mysql.user;"
- Enter password:
- +-----------+--------------+
- | user | host |
- +-----------+--------------+
- | mysql.sys | localhost |
- | root | localhost |
- | test | localhost |
- +-----------+--------------+
- [root@mysql-s ~]# mysql -uroot -p -e "select user,host from mysql.user;"
- Enter password:
- +-----------+--------------+
- | user | host |
- +-----------+--------------+
- | mysql.sys | localhost |
- | root | localhost |
- | test | localhost |
- +-----------+--------------+
结论:此种模式下此配置对默认的库不生效,因此调整配置
- replicate-ignore-db = mysql
- #忽略指定不同步的库
- replicate-wild-ignore-table=mysql.%
- #忽略指定不同步的库的所有表
- [root@mysql-m ~]# mysql -uroot -p -e "grant all privileges on *.* to testuser@localhost identified by '123456';"
- Enter password:
- [root@mysql-m ~]# mysql -uroot -p -e "select user,host from mysql.user;"
- Enter password:
- +-----------+--------------+
- | user | host |
- +-----------+--------------+
- | mysql.sys | localhost |
- | root | localhost |
- | test | localhost |
- | testuser | localhost |
- +-----------+--------------+
- [root@mysql-s ~]# mysql -uroot -p -e "select user,host from mysql.user;"
- Enter password:
- +-----------+--------------+
- | user | host |
- +-----------+--------------+
- | mysql.sys | localhost |
- | root | localhost |
- | test | localhost |
- +-----------+--------------+
结论:此种模式下此配置对默认的库进行不同步数据库,需要增加相关表的参数,***测试得出不加replicate-ignore-db = mysql参数,同样对默认的库生效,
2、binlog-format=STATEMENT模式
修改主从库的binlog模式
一起测试不存在的库、存在的库与默认库
- replicate-ignore-db = test
- #忽略指定不同步的库(主从不存在)
- replicate-ignore-db = test001
- #忽略指定不同步的库
- replicate-wild-ignore-table=mysql.%
- #忽略指定不同步的库的所有表
1:测试默认库数据同步
- mysql> grant all privileges on *.* to user@'localhost' identified by '123456';
- Query OK, 0 rows affected, 1 warning (0.03 sec)
- mysql> select user,host from mysql.user;
- +-----------+--------------+
- | user | host |
- +-----------+--------------+
- | rep | % |
- | mysql.sys | localhost |
- | root | localhost |
- | test | localhost |
- | user | localhost |
- +-----------+--------------+
- 5 rows in set (0.01 sec)
- [root@mysql-s ~]# mysql -uroot -p -e "select user,host from mysql.user;"
- Enter password:
- +-----------+--------------+
- | user | host |
- +-----------+--------------+
- | rep | % |
- | mysql.sys | localhost |
- | root | localhost |
- | test | localhost |
- +-----------+--------------+
结论:在此种模式下,对于默认的库,配置replicate-ignore-db = mysql,对默认的库与库中的表都生效
2:测试主从都不存在的库同步
3:测试主从服务器库已经同步的情况下数据同步(test001)
- mysql> use test001;
- Database changed
- mysql> create table test001 (
- -> id varchar(10) not null,
- -> name varchar(10) not null
- -> );
- Query OK, 0 rows affected (0.06 sec)
- mysql> insert into test001 values('zhang','man');
- Query OK, 1 row affected (0.11 sec)
- [root@mysql-m ~]# mysql -uroot -p -e "select * from test001.test001;"
- Enter password:
- +-------+------+
- | id | name |
- +-------+------+
- | zhang | man |
- +-------+------+
- [root@mysql-s ~]# mysql -uroot -p -e "select * from test001.test001;"
- Enter password:
- ERROR 1146 (42S02) at line 1: Table 'test001.test001' doesn't exist
