mysqld --initialize 错误：mysqld: Can‘t create/write to file ‘G: ool\mysql\data\is_writable‘

 

最近准备在windows下新部署一个mysql绿色版本。发现出现这个问题，提示我的目录不存在。

G:\tool\mysql\bin>mysqld --initialize
mysqld: Can't create/write to file 'G:  ool\mysql\data\is_writable' (Errcode: 2 - No such file or directory)

我发现电脑明明有个这个目录，mysql却找不到。

然后我注意到这一段，mysql打出来的日志，tool文件夹的“t”不见了，我尝试了各种方式，只要以打t头就会有问题。

G:  ool\mysql\data\is_writable' (Errcode: 2 - No such file or directory)

最后我发现\t 有转义的成空格情况。原理是 \t 在数据传输的时候被转义成了空格。

然后实验换成n开头的目录，果然换行了。

G:\nool\mysql\bin>mysqld --initialize
mysqld: Can't create/write to file 'G:
ool\mysql\data\is_writable' (Errcode: 2 - No such file or directory)

解决办法：单斜杆换成双斜杆，G:\\tool\\mysql\\data
