本篇内容主要讲解"Mysql 5.6库级表级复制的搭建方法"，感兴趣的朋友不妨来看看。本文介绍的方法操作简单快捷，实用性强。下面就让小编来带大家学习"Mysql 5.6库级表级复制的搭建方法"吧!

0. 架构信息
主库：192.168.56.100
从库：192.168.56.200

1. 主库操作
关闭数据库
[root@localhost test]# mysqladmin -uroot -p shutdown
Enter password:

修改配置文件
[root@localhost test]# vim /etc/my.cnf
[mysqld]

server-id=100
log-bin=/var/lib/mysql/mysqld-bin
binlog_format=row
# 复制的数据库
binlog-do-db=test

启动数据库
[root@localhost test]# mysqld_safe --defaults-file=/etc/my.cnf &

可以通过下面命令查看要复制的数据库
[root@localhost test]# mysql -uroot -p
Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.

mysql> show master status;
+-------------------+----------+--------------+------------------+-------------------+
| File | Position | Binlog_Do_DB | Binlog_Ignore_DB | Executed_Gtid_Set |
+-------------------+----------+--------------+------------------+-------------------+
| mysqld-bin.000003 | 120 | test | | |
+-------------------+----------+--------------+------------------+-------------------+
1 row in set (0.00 sec)

创建复制用户
mysql> GRANT REPLICATION SLAVE ON *.* to 'repliform'@'%' identified by 'repliform';
Query OK, 0 rows affected (0.00 sec)

2. 从库操作
关闭数据库
[root@localhost tmp]# mysqladmin -uroot -p shutdown
Enter password:

增加复制参数到配置文件中
[root@localhost tmp]# vim /etc/my.cnf
[mysqld]
server-id=200
log-bin=/var/lib/mysql/mysqld-bin
binlog_format=row
# 应用复制的表
replicate_do_table= test.emp
replicate_do_table= test.dept

配置复制
mysql> CHANGE MASTER TO
-> MASTER_HOST='192.168.56.100',
-> MASTER_PORT=3306,
-> MASTER_USER='repliform',
-> MASTER_PASSWORD='repliform',
-> master_log_file='mysqld-bin.000001',
-> master_log_pos=120;
Query OK, 0 rows affected, 2 warnings (0.06 sec)

mysql> show slave status\G

3. 测试同步效果
在主库上面插入数据
mysql> insert into emp values (60), (70);
Query OK, 2 rows affected (0.00 sec)
Records: 2 Duplicates: 0 Warnings: 0

mysql> insert into dept values (60), (70);
Query OK, 2 rows affected (0.02 sec)
Records: 2 Duplicates: 0 Warnings: 0

mysql> commit;
Query OK, 0 rows affected (0.00 sec)

在从库上面查看同步效果
mysql> select * from test.emp;
+------+
| id |
+------+
| 10 |
| 20 |
| 30 |
| 40 |
| 50 |
| 60 |
| 70 |
+------+
7 rows in set (0.00 sec)

mysql> select * from test.dept;
+--------+
| deptno |
+--------+
| 10 |
| 20 |
| 30 |
| 40 |
| 50 |
| 60 |
| 70 |
+--------+
7 rows in set (0.00 sec)
