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）。

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。

[plain] # 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.

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。）
