mysql有時候忘記密碼了怎麼辦?我給出案例和說明!一下就解決了!
Windows下的實際操作如下
1.關閉正在運行的MySQL。
2.打開DOS視窗,轉到mysqlbin目錄。
3.輸入mysqld --skip-grant-tables回車。 如果沒有出現提示資訊,那就對了。
4.再開一個DOS視窗(因為剛才那個DOS視窗已經不能動了),轉到mysqlbin目錄。
5.輸入mysql回車,如果成功,將出現MySQL提示符 >
6. 連接許可權資料庫>use mysql; (>是本來就有的提示符,別忘了最後的分號)
6.改密碼:> update user set password=password("520") where user="root"; (別忘了最後的分號)
7.刷新許可權(必須的步驟)>flush privileges;
8.退出 > q
9.登出系統,再進入,開MySQL,使用使用者名root和剛才設置的新密碼123456登陸。
