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。
