主库：记住 File 和 Position

CREATE USER 'slave'@'MySql2服务器ip' IDENTIFIED BY '密码';
GRANT REPLICATION SLAVE ON *.* TO 'slave'@'MySql2服务器ip';
 
flush privileges;

show master status;

从库：

CHANGE MASTER TO 
master_host = 'MySql1服务器ip',   
master_user = 'slave',  
master_password = '密码',  
master_log_file = 'bin_log.000002',  
master_log_pos = 631;

start slave;

show slave status\G

最后显示：

代表成功。
