    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:WindowsSystem32cmd.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-winx64in>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

    下面是我的安装过程;
    C:Windowssystem32>d:

    D:mysql-8.0.18-winx64in>mysqld install
    Service successfully installed.

    D:mysql-8.0.18-winx64in>net start mysql
    发生系统错误 193。

    *** 不是有效的 Win32 应用程序。
