mysql下载安装记录

设备情况：win10，之前没有进行过mysql安装。
一下载：直接官网下载，https://dev.mysql.com/downloads/file/?id=490026 下载的是解压版的。版本8.0.18 压缩包270M左右。下载完之后解压。

二安装 ： 参照 https://www.runoob.com/mysql/mysql-install.html 注意：cmd要用 【管理员权限】启动->在这里C:\Windows\System32\cmd.exe 然后运行到mysqld -install的时候
下一步net start mysql 可能会出错：

D:\mysql-8.0.18-winx64\bin>net start mysql
发生系统错误 193。

*** 不是有效的 Win32 应用程序。

这时候看这篇博客，原理好像是第一次默认安装在c盘，需要手动删除，然后remove一下，再次安装，就到你的指定的目录了。然后再net启动，就成功了
