请帮助我。我在数据库中有非常重要的文件。

解决!

  1. Open AMPPS Application -> MySQL Tab -> Configuration.

  2. [mysqld]部分,添加以下行: innodb_force_recovery = 1

  3. 保存文件并尝试启动MySQL的

  4. 删除刚才添加该行并保存。

而不是删除表彰会更好的选择因为每次更新后问题再次发生。 –

只是为了增加哈利斯的观点 - 评论是做这件事的一个很好的方式 - 只是在行前面的单个哈希:#。 – user319940

这也发生在OS X Yosemite崩溃后,但这些步骤将对其进行排序。 –

所以我面临着类似的问题,我的尝试是以下几点: -

find/-name mysql

从上面命令的输出中删除所有的搜索results.Then做以下操作: -

brew uninstall mysql 
brew clean 

然后重新启动您的机器一次,然后再次安装使用以下内容: -

brew install mysql 

PS:我得到这个错误error所以我不能把我的数据库的备份,但我没有那么多的重要数据在DB所以我删除它,反正
