mysql忘记密码

先关闭mysql服务

[root@localhost ~]# service mysql status
Redirecting to /bin/systemctl status  mysql.service
● mysql.server.service - LSB: start and stop MySQL
   Loaded: loaded (/etc/rc.d/init.d/mysql.server; bad; vendor preset: disabled)

     Docs: man:systemd-sysv-generator(8)
  Process: 9580 ExecStop=/etc/rc.d/init.d/mysql.server stop (code=exited, status=0/SUCCESS)
  Process: 2417 ExecStart=/etc/rc.d/init.d/mysql.server start (code=exited, status=0/SUCCESS)

用mysqld_safe启动mysql，并--skip-grant-tables跳过权限的审核。

[root@localhost ~]# mysqld_safe --skip-grant-tables &   

登录

[root@localhost ~]# mysql --user=root mysql

这样就能进入mysql环境中，修改用户密码。将root用户密码设置为111111

mysql> update user set authentication_string=PASSWORD('111111') WHERE User='root';

刷新下权限

mysql> flush privileges;
Query OK, 0 rows affected (0.06 sec)

mysql> QUIT;

然后用新密码登录就可以进入

[root@localhost ~]# mysql -uroot -p111111
