上一次安装完成Mysql5.6服务，一段时间后发生异常，Mysql服务无法启动进程终止： 1067；网上找了好多方法还是没能解决这个问题，今天重新安装Mysql5.6，同样出现这个问题，后来通过阅读

MySQL 5.6 Reference Manual Including MySQL Cluster NDB 7.3 Reference Guide

这个问题最终得以解决了。

  下面是安装Mysql On Windows 解压安装方式。

1. 下载Mysql安装包：mysql-5.6.12-win32.zip；

2. 解压安装到D:\__dev下；

3. 添加环境变量，创建MYSQL_HOME变量，

   1	MYSQL_HOME=D:\__dev\mysql-5.6.12-win32

   配置Path路径，、bin

   1	%MYSQL_HOME%\bin;

4. 修改mysql-5.6.12-win32下的my-default.ini文件

1 2 3 4 5 6

#Path to installation directory. All paths are usually resolved relative to this. #basedir="C:/Program Files/MySQL/MySQL Server 5.0/" basedir = D:/__dev/mysql-5.6.12-win32 #Path to the database root #datadir="C:/Program Files/MySQL/MySQL Server 5.0/Data/" datadir = D:/__dev/mysql-5.6.12-win32/data

  如上图配置basedir和datadir.

  在开发指南上有精简配置如下图：

5. 使用管理员权限运行命令窗口，切换工作目录为Path目录下，安装Mysql服务

1 2 3

mysqld -install 出现Service successfully installed. 表示安装服务成功

6. 启动mysql服务

1	net start mysql

7.登录到mysql，并修改root用户密码，默认为空

1 2	mysql>mysq -uroot mysql>update mysql.user set password=PASSWORD('root') where User='root'

问题解决了，mysql5.6的配置文件在安装目录下，名字已经变为my-default.ini.

详细配置信息如下：
