问题表现

如下初始化命令均无反应

--initialize-insecure
--initialize
--initialize --console

执行结果如下：

PS D:\mysql-5.7.41-winx64> .\bin\mysqld --initialize --console
PS D:\mysql-5.7.41-winx64>

原因及解决办法

原因

缺少了Microsoft Visual C++ Redistributable软件包

如果下载的不是.zip版本，而是.msi版本，就可以看到缺少软件包的提示了。

如下是mysql 5.7.44的提示，需要 VC 2019 Redistributable：

解决办法

下载需要的Visual C++ Redistributable软件包，然后重新使用mysqld --initialize初始化
