mysql忘記密碼找回的方法：
在找回之前需要對 --skip-networking 參數進行了解
--skip-grant-tables: 關閉mysql驗證模塊
同時還需要關閉遠程連接(避免他人連接修改)
--skip-networking : 關閉TCP/IP連接
知道以上兩個參數后 現在可以進行找回密碼:
使用 mysqld_safe 啟動mysql
mysqld_safe --skip-grant-tables --skip-networking &
啟動完成后 輸入 mysql 即可無密碼登錄
直接插入新的賬號密碼：
INSERT INTO mysql.user VALUES
('localhost',
'root',
PASSWORD('123'),
'Y',
'Y',
'Y',
'Y',
'Y',
'Y',
'Y',
'Y',
'Y',
'Y',
'Y',
'Y',
'Y',
'Y',
'Y',
'Y',
'Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','','','','',
0,0,0,0,'mysql_native_password','','N');
創建成功后,查詢創建的用戶情況:
mysql> select user,host,password from mysql.user;
+------+-----------+-------------------------------------------+
| user | host | password |
+------+-----------+-------------------------------------------+
| root | localhost | *23AE809DDACAF96AF0FD78ED04B6A265E05AA257 |
+------+-----------+-------------------------------------------+
1 row in set (0.00 sec)
驗證結果:
[root@db01 ~]# mysql -uroot -p123
