指向Master

这里的MASTER_LOG_FILE和MASTER_LOG_POS是刚才show master status的值，当然也可以使用more查看应该指定的位置。

CHANGE MASTER TO MASTER_HOST='192.168.1.200',MASTER_PORT=3306,MASTER_USER='repl',MASTER_PASSWORD='slave',MASTER_LOG_FILE='mysql-bin.000045',MASTER_LOG_POS=939;

这里的MASTER_LOG_FILE和MASTER_LOG_POS是刚才show master status的值，当然也可以使用more查看应该指定的位置。

启动slave

这里看到Slave_IO_Running和Slave_SQL_Running双YES一般就没有问题了。

验证

现在可以在主上面进行一些新建数据库、新建数据表、插入输出等方式来验证是否主从生效。此步骤就大家自己随意发挥吧！
