Linux MySQL密碼修改 1)如果您沒有忘記密碼的情況下,可以通過UPDATE直接編輯user表來修改密碼: 進入數據庫mysql -u root mysql> use mysql; mysql> UPDATE user SET Password = PASSWORD('newpass') WHERE user = 'root'; mysql> FLUSH PRIVILEGES; 或者 /etc/init.d/mysql stop /etc/init.d/mysql start 2)如果您已經忘記密碼: # /etc/init.d/mysql stop 1、結束當前正在運行的mysql進程。 # /usr/bin/mysqld_safe --skip-grant-tables 2、用mysql安全模式運行並跳過權限驗證。 # mysql -u root 3、重開一個終端以root身份登錄mysql。 mysql> use mysql; 4、修改root用戶口令。 Reading table information for completion of table and column names You can turn off this feature to get a quicker startup with -A Database changed mysql> update user set Password = PASSWORD('root') where User ='root'; Query OK, 3 rows affected (0.00 sec) Rows matched: 3 Changed: 3 Warnings: 0 mysql> exit # /etc/init.d/mysql restart 5、結束mysql安全模式,用正常模式運行mysql。 mysql> update mysql.user set password=PASSWORD('新密碼') where User='root'; 6、試試你新修改的口令 mysql> flush privileges; mysql> quit
