解決mysql忘記密碼
mysql有時(shí)候忘記密碼了怎么辦?我給出案例和說明!一下就解決了!
Windows下的實(shí)際操作如下
1.關(guān)閉正在運(yùn)行的MySQL。
2.打開DOS窗口,轉(zhuǎn)到mysql\bin目錄。
3.輸入mysqld --skip-grant-tables回車。如果沒有出現(xiàn)提示信息,那就對了。
4.再開一個(gè)DOS窗口(因?yàn)閯偛拍莻€(gè)DOS窗口已經(jīng)不能動(dòng)了),轉(zhuǎn)到mysql\bin目錄。
5.輸入mysql回車,如果成功,將出現(xiàn)MySQL提示符 >
6. 連接權(quán)限數(shù)據(jù)庫>use mysql; (>是本來就有的提示符,別忘了最后的分號)
6.改密碼:> update user set password=password("520") where user="root"; (別忘了最后的分號)
7.刷新權(quán)限(必須的步驟)>flush privileges;
8.退出 > \q
9.注銷系統(tǒng),再進(jìn)入,開MySQL,使用用戶名root和剛才設(shè)置的新密碼123456登陸。
