+------------------+----------+--------------+------------------+-------------------+ 1 row in set (0.00 sec)

解锁表

mysql> UNLOCK TABLES;

远程传文件过去

如果数据文件偏大或者数据多，可以使用percona的xtrabackup进行备份压缩，再传过去。

rsync back.sql root@192.168.1.200:/root

Slave操作

开启binlog设置server-id

在/etc/my.cnf中的mysqld选项下编辑

[mysqld]
log-bin=mysql-bin
server-id=2003306

重启MySQL服务

导入数据

shell>mysqldump -uroot -p --databases t1 <back.sql

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。

shell>more back.sql
-- MySQL dump 10.13  Distrib 5.7.14, for linux-glibc2.5 (x86_64)
--
-- Host: localhost    Database:

CHANGE MASTER TO MASTER_LOG_FILE='mysql-bin.000045', MASTER_LOG_POS=939;

启动slave

mysql>start slave;
mysql>show slave status\G

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！
