MySQL 5.7.14 net start mysql 服務無法啟動-“NET HELPMSG 3534” 的奇怪問題

my.ini

在參考http://www.jb51.net/article/100284.htm之後

執行mysqld --initialize-insecure出現錯誤提示

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)

只好把目錄改成反斜槓

[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 
#解壓目錄 
datadir=D:/Program Files/soft/mysql-5.7.14-winx64/mysql-5.7.14-winx64/data 
#解壓目錄下data目錄 
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 

再次執行成功

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.
