MYSQL主从服务器怎么实现同步                                                      

从服务器每间隔一段时间就到主服务器里面去取bin-log日志,完成操作。

bin-log日志开启                                                                          

Ubuntu

1

重启服务

sudo /etc/init.d/mysql restart
Copy after login

1

Win7

11

bin-log日志的作用                                                                       

image

Flush logs;
Copy after login

此时就会多一个新的bin-log日志。

Show master status;
Copy after login

查看最后一个bin-log日志。

image

对内容进行修改之后再查看。

image

reset master;
Copy after login

清除日志,看到回到了mysql-bin.000001文件。

image

再插入数据之后进行bin-log日志查看。

image

若数据丢失,可用bin-log恢复数据。这种恢复数据的条件对于备完份,然后服务器又开了一段时间之后数据全部丢失了,可以恢复回来一些数据,但是之后的一段时间的数据就需要bin-log来恢复。

个别恢复。

只想回复insert into yyd_table values (5);那个。

完全备份与恢复                                                                             

那么,说到备份,在简单介绍一些备份。

完全恢复

主从设置                                                                                      

Win7,从服务器,设置。

然后重启。

Ubuntu,主服务器,设置。

image

查看配置

测试:

总结&&遇到问题的解决                                                                  

MySQL这个主从可以用到集群服务器上,而且若是在搞访问量期间,也可以在从服务器进行备份。

但是这仅仅只是主从服务器,当主服务器崩溃之后,从服务器不会出来当主服务器的,所以还是不够完美。

在期间,在进行授权之后,我老是不能登录远程的MYSQL,然后百度后将问题解决了。

[mysqld]

skip-name-resolve

skip-grant-tables

跳过MySQL的访问控制,任何人都可以在控制台以管理员的身份进入MySQL。
