我使用安装程序安装了MySQL服务器，然后启动了该服务器。重新启动后，我尝试再次启动它并得到错误：

D:\Program Files\MySQL\MySQL Server 5.7\bin>mysqld -u root -p
mysqld: Can't change dir to 'D:\Program Files\MySQL\MySQL Server 5.7\data\'     (Errcode: 2 - No such file or directory)

我试图重新安装MySQL。

当我mysqld -u root -p以管理员身份运行时，什么都没有发生。

回答：

由于您使用Windows安装程序，因此一切都已设置为可将MySQL 5.7作为Windows服务运行，这在大多数情况下是一个不错的选择。

而不是mysqld.exe从命令行运行，

  1. Win + R

  2. 跑 services.msc

  3. 右键点击 MySQL57

  4. 启动服务。
