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 Warning: Using a password on the command line interface can be insecure. Welcome to the MySQL monitor. Commands end with ; or \g.

重新启动数据库 改为正常模式(不再使用--skip-grant-tables --skip-networking)
