MySQL 5.7.14 net start mysql 服务无法启动-“NET HELPMSG 3534” 的奇怪问题

my.ini

在参考https://www.jb51.net/article/100284.htm之后

执行mysqld --initialize-insecure出现错误提示

C:\WINDOWS\system32>mysqld --initialize-insecure
mysqld: Can't create directory 'D:\Program Files oft\mysql-5.7.14-winx64\mysql-5.7.14-winx64\data\' (Errcode: 2 - No such file or directory)

只好把目录改成反斜杠

[client]
port=3306
default-character-set=utf8
[mysqld]
port=3306
character_set_server=utf8
basedir=D:/Program Files/soft/mysql-5.7.14-winx64/mysql-5.7.14-winx64
#解压目录
datadir=D:/Program Files/soft/mysql-5.7.14-winx64/mysql-5.7.14-winx64/data
#解压目录下data目录
sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES
[WinMySQLAdmin]
D:/Program Files/soft/mysql-5.7.14-winx64/mysql-5.7.14-winx64/bin/mysqld.exe

再次执行成功

C:\WINDOWS\system32> mysqld install MySQL --defaults-file="D:\Program Files\soft\mysql-5.7.14-winx64\mysql-5.7.14-winx64\my.ini"
Service successfully installed.
C:\WINDOWS\system32>net start mysql

MySQL 服务正在启动 . 

MySQL 服务已经启动成功。
