今天在重新安装MySQL服务的时候遇到如下错误：
C:\Program Files\MySQL\MySQL Server 4.1\bin>MySQLd-nt --remove
Service successfully removed.
C:\Program Files\MySQL\MySQL Server 4.1\bin>MySQLd-nt --install
Service successfully installed.
C:\Program Files\MySQL\MySQL Server 4.1\bin>net start MySQL
The MySQL service is starting.
The MySQL service could not be started.
A system error has occurred.
System error 1067 has occurred.
The process terminated unexpectedly.
发现一种最简单的方法：把MySQL目录下的my.ini copy到C:\WINDOWS中，再重新安装服务问题解决：
C:\Program Files\MySQL\MySQL Server 4.1>copy my.ini c:\WINDOWS\
1 file(s) copied.
C:\Program Files\MySQL\MySQL Server 4.1>MySQLd-nt --remove
Service successfully removed.
C:\Program Files\MySQL\MySQL Server 4.1>MySQLd-nt --install
Service successfully installed.
C:\Program Files\MySQL\MySQL Server 4.1>net start MySQL
The MySQL service is starting.
The MySQL service was started successfully.
网上有人给出了另外一个解决方法，比较麻烦，相信也是可行的：
把MySQL目录copy到c:\MySQL
copy my.ini到C:\WINDOWS目录
修改my.ini中basedir和datadir参数
重新install MySQL service
谁不嫌麻烦可以试一下。
