1.首先我们需要跳过 MySQL 的密码认证:

  (1)进入 /etc/my.cnf 文件

[root@localhost ~]# vim /etc/my.cnf

  (2)在 [mysqld] 的下面添加 " skip-grant-tables " 用来跳过 MySQL 登录时候的密码验证:

[mysqld]
skip-grant-tables

 

2.重启下 MySQL :

[root@localhost lib]# systemctl restart mysqld.service

 

3.进入 MySQL 中使用命令对密码进行修改:

//使用名字叫 mysql(或者自己创建过) 数据库
mysql>
use mysql; Reading table information for completion of table and column names You can turn off this feature to get a quicker startup with -A Database changed
//这里我把 账号 root 密码设置为 root mysql
> update mysql.user set authentication_string=password('root') where user='root' ; Query OK, 1 row affected, 1 warning (0.00 sec) Rows matched: 1 Changed: 1 Warnings: 1
// 刷新 mysql>
flush privileges; Query OK, 0 rows affected (0.00 sec) mysql> quit Bye

 

4.验证是否对密码重新设置成功:

[root@localhost /]# mysql -uroot -proot
//注意:这里一般直接输入密码登录,可能会不安全
mysql: [Warning] Using a password on the command line interface can be insecure. Welcome to the MySQL monitor. Commands end with ; or \g.
