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 |
