  • 实验步骤

1、如果MySQL服务正在运行,则需要先停止服务

systemctl stop mysqld

2、编辑MySQL配置文件

vim /etc/my.cnf

在[mysqld]中增加一行:
skip-grant-tables

3、开启mysql服务

systemctl start mysqld

4、使用命令直接登录数据库(无需密码)

[root@localhost ~]# mysql -uroot -p     ## 登录数据库
Enter password:          ## 这里密码为空,直接回车

mysql>        ## 已经登录成功了

5、登录进数据库中后下一步就是重置root密码

update mysql.user set authentication_string=password('123123') where user='root';   ##重置root用户密码为123123

6、将配置文件中添加的 “skip-grant-tables” 这一行删去,开启数据库服务

systemctl start mysqld

使用重新修改后的密码123123就可以登录数据库了
