mysql数据库跳过密码设置密码的方法

mysql数据库跳过密码设置密码的方法主要是通过修改配置文件的方法

root@host51 ~]# vim /etc/my.cnf

[mysqld]
skip-grant-tables  -----添加此行,该行的意思是跳过授权
#validate_password_policy=0
#validate_password_length=6
[root@host51 ~]# systemctl restart mysqld
[root@host51 ~]# mysql 
mysql> update mysql.user
    -> set
    -> authentication_string=password("654321")
    -> where
    -> user="root" and host="localhost";

Query OK, 1 row affected, 1 warning (0.06 sec)
Rows matched: 1  Changed: 1  Warnings: 1

在更改密码之后需要恢复之前的设置

root@host51 ~]# vim /etc/my.cnf

[mysqld]
#skip-grant-tables  
validate_password_policy=0
validate_password_length=6

[root@host51 ~]# systemctl restart mysqld

[root@host51 ~]# mysql -uroot -p654321

mysql>alter user root@"localhost" identified by "123456"; 

Query OK, 1 row affected, 1 warning (0.06 sec)
