Linux mysql master

My.cnf:

server_id = 1   #从服务器标识，范围1---2E32-1

log_bin = mysql_bin

binlog_do_db = studyyii

binlog_do_db = mysql

mysql service restart

windows mysql slave

mysql.ini:

[mysqld]

port=3306

server-id = 2

replicate-do-db = study

重启mysql

登陆mysql

mysql> stop
slave;

mysql> change
master to
master_host=‘192.168.1.200‘,master_user=‘root‘,master_password=‘123456‘;

mysql> start
slave;

mysql> show
slave status\G;

查看这两项是否为YES，yes为正常。

Slave_IO_Running:
Yes

Slave_SQL_Running:
Yes
