【MySQL安装问题】mysqld --initialize初始化报错

在显示安装成功Mysql后，初始化mysqld --initialize报错，错误显示如下

2023-04-03T709:05:28.842980Z O[Warning] TMESTAMP with implicit DEFAULT walue is deprecated.Please use -explicit_lefatlts_for_timestamp server option (see documentation for more details).

报错大致意思是所在数据文件夹不为空

解决方法：打开MySQL安装目录，在mysql-5.7.41-winx64目录下有一个data文件夹，把整个data删除，再重新mysqld --initialize初始化，会得到一个新的data，接着输入net start mysql启动成功

该报错的可能原因：之前安装过MySQL，没删干净，导致初始化数据库时data还有之前的数据
