MYSQL服務無法啟動，提示資訊1067解決辦法

不得不吐槽mysql5.1這個版本實在是太不穩定了，重啟了一下mysql服務就崩潰了。

百度了好多部落格，說什麼修改my.ini檔案就行了，尼瑪都不行，還是Google靠譜，解決辦法就是徹底卸載之後重新安裝。

重新下載了mysql5.6的noinstall版本，解壓縮到D盤檔案夾命名為mysql。

1、 進入cmd  輸入命令： sc delete mysql 提示若是delete service success,證明刪除服務成功; 

2、備份mysql5.1檔案夾下的my.ini檔案後直接將mysql5.1檔案夾全部刪除
（my.ini檔案的配置請看我的這篇部落格http://blog.csdn.net/jkxqj/article/details/9986731）。

3、開始->運行-> regedit 看看註冊表裡這幾個地方刪除沒有 
　　HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\Eventlog\Application\MySQL 目錄刪除 
　　HKEY_LOCAL_MACHINE\SYSTEM\ControlSet002\Services\Eventlog\Application\MySQL 目錄刪除 
　　HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Eventlog\Application\MySQL 目錄刪除（我卸載的時候沒有找到，略過後仍達到完全卸載的目的。） 

卸載完之後就重新安裝吧。

4、新的檔案夾名字為mysql，將之前備份的my.ini檔案修改一下，我這裡就直接貼我的了。

5、以管理員身份運行cmd。進入D盤，然後輸入複製以下命令：

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

出現Servicesuccessfully installed.表示安裝成功。

然後開啟服務視窗（在運行框中輸入services.msc即可開啟服務視窗，然後可以找到mysql服務了）

6.啟動MySQL服務
net start mysql
MySQL服務正在啟動 

5．登陸MySQL伺服器
mysql -u root -p
Enterpassword:（root密碼自己設定就好了，注意：MySQL的管理使用者名為root，密碼預設為空白。）
