今天碰到一個特別鬱悶的問題，啟動mysql資料庫時報錯：[ERROR] Found option without preceding group in config file /etc/my.cnf at line 1!經過查詢資料，說的都是：

原因：my.ini檔案格式是utf-8

解決辦法，my.ini檔案儲存為ANSI格式檔案

但是我的改了也沒有用處，後來才發現,不知道什麼時候，我刪除了一個#：

# Remove leading # to turn on a very important data integrity option: logging

# Remove leading # to set options mainly useful for reporting servers.
