恢复Mysql数据_MySQL

May 31, 2016 am 08:46 AM

今天由于误操作,需要更换操作系统,然而Mysql的数据并没有做定期的备份,只能拿到数据库原始的格式,需要恢复,大概需要以下几步:

  1. 找到Mysql的data目录
  2. 将wordpress目录(是你要恢复的目录)和ibdata1两个文件拷贝出来
  3. 安装跟原来数据相同版本的Mysql
  4. 将上述两个文件拷贝到新数据库的data目录下
  5. 删除新数据库的ib_logfile0和ib_logfile1两个文件
  6. 重启新数据库
  7. 使用客户端或mysqldump备份数据库成wordpress.sql

恢复有点麻烦,新装的数据也只是用来恢复,并不能正式使用,正式使用最好还是将备份出来的wordpress.sql恢复的一个新的数据库;所以还是要做好定时备份的工作,以防硬盘都坏掉的情况发生

备份方法

backup.bat

<code>@echooffset "Ymd=%date:~,4%%date:~5,2%%date:~8,2%"c:/path/to/mysqldump wordpress > d:/path/to/dmp/wordpress_%Ymd%.sql</code>
Copy after login

my.ini设置

<code>[mysqldump]user=rootpassword=password</code>
Copy after login
