MYSQL服务无法启动，提示信息1067解决办法

不得不吐槽mysql5.1这个版本实在是太不稳定了，重启了一下mysql服务就崩溃了。

百度了好多博客，说什么修改my.ini文件就行了，尼玛都不行，还是谷歌靠谱，解决办法就是彻底卸载之后重新安装。

重新下载了mysql5.6的noinstall版本，解压缩到D盘文件夹命名为mysql。

1、 进入cmd  输入命令： sc delete mysql 提示若是delete service success,证明删除服务成功; 

2、备份mysql5.1文件夹下的my.ini文件后直接将mysql5.1文件夹全部删除 （my.ini文件的配置请看我的这篇博客http://blog.csdn.net/jkxqj/article/details/9986731）。

3、开始->运行-> regedit 看看注册表里这几个地方删除没有 
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\Eventlog\Application\MySQL 目录删除 
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet002\Services\Eventlog\Application\MySQL 目录删除 
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Eventlog\Application\MySQL 目录删除（我卸载的时候没有找到，略过后仍达到完全卸载的目的。） 

卸载完之后就重新安装吧。

4、新的文件夹名字为mysql，将之前备份的my.ini文件修改一下，我这里就直接贴我的了。

 

# Example MySQL config file for small systems.

#

# This is for a system with little memory (<= 64M) where MySQL is only used

# from time to time and it's important that the mysqld daemon

# doesn't use much resources.

#

# MySQL programs look for option files in a set of

# locations which depend on the deployment platform.

# You can copy this option file to one of those

# locations. For information about these locations, see:

# http://dev.mysql.com/doc/mysql/en/option-files.html

#

# In this file, you can use all long options that a program supports.

# If you want to know which options a program supports, run the program

# with the "--help" option.



# The following options will be passed to all MySQL clients

[client]

#password	= your_password

# Don't listen on a TCP/IP port at all. This can be a security enhancement,

# (using the "enable-named-pipe" option) will render mysqld useless!

5、以管理员身份运行cmd。进入D盘，然后输入复制以下命令：

D:\mysql\bin\mysqld -install mysql --defaults-file="D:\mysql\my.ini"

出现Servicesuccessfully installed.表示安装成功。

 

然后打开服务窗口（在运行框中输入services.msc即可打开服务窗口，然后可以找到mysql服务了）

6.启动MySQL服务
net start mysql
MySQL服务正在启动 

5．登陆MySQL服务器
mysql -u root -p
Enterpassword:（root密码自己设置就好了，注意：MySQL的管理员用户名为root，密码默认为空。）
