Master my.ini

1. basedir = D:\mysql_test\mysql-5.7.17-master
   

2. datadir = D:\mysql_test\mysql-5.7.17-master\data
   

3. port = 3306
   

4. log-bin=mysql-bin
   

5. server_id=1
   

6. binlog-ignore-db=information_schema
   

7. binlog-ignore-db=cluster
   

8. binlog-ignore-db=mysql
   

9. binlog-do-db=test

Slave my.ini

1. basedir = D:\mysql_test\mysql-5.7.17-slave
   

2. datadir = D:\mysql_test\mysql-5.7.17-slave\data
   

3. port = 3307
   

4. log-bin=mysql-bin
   

5. server-id=2
   

6. binlog-ignore-db=information_schema
   

7. binlog-ignore-db=cluster
   

8. binlog-ignore-db=mysql
   

9. replicate-do-db=test
   

10. replicate-ignore-db=mysql
    

11. log-slave-updates
    

12. slave-skip-errors=all
    

13. slave-net-timeout=60

Master 运行
mysql> CREATE USER 'rep'@'%' IDENTIFIED BY 'rep';
mysql> GRANT FILE ON *.* TO 'rep'@'%' IDENTIFIED BY 'rep';
mysql> GRANT REPLICATION SLAVE ON *.* TO 'rep'@'%' IDENTIFIED BY 'rep';
mysql> FLUSH PRIVILEGES;

mysql> show master status;
+------------------+----------+--------------+----------------------------------+-------------------+
| File             | Position | Binlog_Do_DB | Binlog_Ignore_DB                 | Executed_Gtid_Set |
+------------------+----------+--------------+----------------------------------+-------------------+
| mysql-bin.000002 |     4570 | test         | information_schema,cluster,mysql |                   |
+------------------+----------+--------------+----------------------------------+-------------------+

Slave 运行
mysql> CREATE USER 'rep'@'%' IDENTIFIED BY 'rep';
mysql> change master to master_host='localhost',master_user='rep',master_password='rep',master_log_file='mysql-bin.000002', master_log_pos=4570;

mysql> start slave;
mysql> show slave status;

Slave_IO_Running 和 Slave_SQL_Running都是 Yes 表示成功。
Master创建数据库，创建表，添加数据，会自动复制到Slave。
