XAMPP的MYSQL无法启动

昨天用各种方式试验MYSQL的数据库备份与恢复操作，恢复过程中，MYSQL就无法启动了。

提示如下：

22:59:43  [mysql]     Attempting to start MySQL app...
22:59:43  [mysql]     Status change detected: running
22:59:44  [mysql]     Status change detected: stopped
22:59:44  [mysql]     Error: MySQL shutdown unexpectedly.
22:59:44  [mysql]     This may be due to a blocked port, missing dependencies, 
22:59:44  [mysql]     improper privileges, a crash, or a shutdown by another method.

This may be due to a blocked port, missing dependencies, 首先我看了端口，3306端口并没有被占用。

网上看到一个运行批处理文件的解决办法，但是需要重启：

 我就X了，刚刚写了一大堆，结果提交后显示找不到服务器，，，，然后草稿箱里也没有，真是各种背

总之就是各种方法都试了，都无法解决，最后只能重新卸载重装解决的。

刚才将E:xampp_newmysqldata 数据库的文件替换了一下，替换后，mysql就无法启动了，终于找到了mysql无法启动的原因，就是因为替换data数据库文件造成的。

多次删除ibdata1、ib_logfile1、ib_logfile0 后，mysql才可以启动，第一次删除后，确实依然无法启动。

通过操作发现，使用直接复制、粘贴数据库文件的方法，对数据库进行恢复，是不可行的，会造成数据库无法启动，就算后面删除日志文件，数据库可以启动了，也是无法浏览数据库内的表文件的。
