  使用MYSQL进行数据库备份,有很正规的数据库备份方法,同其他的数据库服务器有相同的概念,但有没有想过,MySQL会有更简捷的使用文件目录的备份方法,而且又快有好。   

  一、数据备份捷径   

  因为这个方法没有得到官方正式文档的验证,我们暂称为试验吧。   

  目的:备份hostA主机中一个mysql数据库TestA,并恢复到到hostB机中  

  试验环境:   

  操作系统:WinNT4.0,Mysql3.22.34,phpMyAdmin 2.1.0   

  在hostA中安装mysql数据库并建立TestA数据库  

  hostB机安装mysql数据库,没有TestA数据库  

  方法步骤:   

  启动phpMyAdmin察看HostA和HostB中的数据库列表,在HostB中没有TestA数据库   

  找到HostA中mysql的安装目录,并找到数据库目录data   

  在我的试验环境中,这个目录是   

  C:mysqldata   

  找到对应数据库名称的子目录   

  C:mysqldataTestA   

  粘贴拷贝到HostB的Data目录下,是HostA同HostB Mysql数据目录下的文件相同。 

  刷新HostB的phpMyAdmin察看一下数据库列表,我们看到TestA已经出现,并且作查询修改等操作都正常,备份恢复恢复成功。

  试验结论:Mysql的数据库可以通过文件形式保存,备份,恢复只要将相应文件目录恢复即可,无需使用其它工具备份。   

  二、正规的方法(官方建议):

  导出要用到MySQL的mysqldump工具,基本用法是:   

  mysqldump [OPTIONS] database [tables]  

  如果你不给定任何表,整个数据库将被导出。  

  通过执行mysqldump --help,你能得到你mysqldump的版本支持的选项表。
