我最近开始使用网络开发。我需要一个好的服务器来运行PHP和mySQL应用程序。我现在面临的问题是每当我打开xampp时mySQL都会崩溃。我已经阅读了StackOverflow上的大多数线程，并且还重新配置了端口，从C：// xampp / mysql / data中删除了ibdata1和崩溃文件，但仍然没有任何反应。日志数据和错误代码如下：
Error: MySQL shutdown unexpectedly.
12:11:09 [mysql] This may be due to a blocked port, missing dependencies,
12:11:09 [mysql] improper privileges, a crash, or a shutdown by another method.
12:11:09 [mysql] Press the Logs button to view error logs and check
12:11:09 [mysql] the Windows Event Viewer for more clues
12:11:09 [mysql] If you need more help, copy and post this
12:11:09 [mysql] entire log window on the forums
，mysqlerror.log中的数据如下：

This could be because you hit a bug. It is also possible that this binary
or one of the libraries it was linked against is corrupt, improperly built,
or misconfigured. This error can also be caused by malfunctioning hardware.
To report this bug, see https://mariadb.com/kb/en/reporting-bugs
We will try our best to scrape up some info that will hopefully help
diagnose the problem, but since we have already crashed,
something is definitely wrong and this may fail.
Server version: 10.1.32-MariaDB
key_buffer_size=16777216
read_buffer_size=262144
max_used_connections=0
max_threads=1001
thread_count=0
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 787129 K bytes of memory
Hope that's ok; if not, decrease some variables in the equation.

当您发布包含您正在使用的软件版本的任何问题时，这是一个很好的做法 请试试这个
exit Xampp server go to your C:\xampp\mysql\data directory delete the ibdata1 file restart xampp server 如果它在步骤3中无效：您还可以删除此ib_logfile0
