mysql忘记密码找回的方法

mysql忘记密码找回的方法：
在找回之前需要对 --skip-networking 参数进行了解
--skip-grant-tables: 关闭mysql验证模块

同时还需要关闭远程连接(避免他人连接修改)
--skip-networking : 关闭TCP/IP连接

知道以上两个参数后 现在可以进行找回密码:
使用 mysqld_safe 启动mysql

mysqld_safe --skip-grant-tables --skip-networking &

启动完成后 输入 mysql 即可无密码登录

直接插入新的账号密码：

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');

创建成功后,查询创建的用户情况:

mysql> select user,host,password from mysql.user;
+------+-----------+-------------------------------------------+
| user | host      | password                                  |
+------+-----------+-------------------------------------------+
| root | localhost | *23AE809DDACAF96AF0FD78ED04B6A265E05AA257 |
+------+-----------+-------------------------------------------+
1 row in set (0.00 sec)

验证结果:

[root@db01 ~]# mysql -uroot -p123
