MYSQL服務無法啟動，提示信息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。 百度了好多博客，說什麼修改my.ini文件就行了，尼瑪都不行，還是谷歌靠譜，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盤文件夾命名為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文件夾下的my.ini文件後直接將mysql5.1文件夾全部刪除）。 3、開始->運行-> regedit 看看注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、新的文件夾名字為mysql，將之前備份的my.ini文件修改一下，我這裡就直接貼我的了。
[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、以管理員身份運行cmd。進入D盤，然後輸入復制以下命令： D:\mysql\bin\mysqld -install mysql --defaults-file="D:\mysql\my.ini" 出現Servicesuccessfully installed.表示安裝成功。 然後打開服務窗口（在運行框中輸入services.msc即可打開服務窗口，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服務器 mysql -u root -p Enterpassword:（root密碼自己設置就好了，注意：MySQL的管理員用戶名為root，密碼默認為空。）
