快速修复损坏的MySQL数据库_MySQL
bitsCN.com
1、myisamchk
使用 myisamchk 必须暂时停止 MySQL 服务器。例如，我们要检修 discuz 数据库。执行以下操作：
# service mysql stop (停止 MySQL )；
# myisamchk -r /数据库文件的绝对路径/*MYI
# service mysql start
myisamchk 会自动检查并修复数据表中的索引错误。
2、mysqlcheck
使用 mysqlcheck 无需停止 MySQL ，可以进行热修复。操作步骤如下：
# mysqlcheck -r discuz.*
# service mysql stop (停止 MySQL )；
# myisamchk -r /数据库文件的绝对路径/*MYI
# service mysql start
myisamchk 会自动检查并修复数据表中的索引错误。
注意，无论是 myisamchk 还是 mysqlcheck ，一般情况下不要使用 -f 强制修复，-f 参数会在遇到一般修复无法成功的时候删除部分出错数据以尝试修复。所以，不到万不得已不要使用 -f。
