1、root用户登录到mysql数据库

/usr/local/mysql/bin/mysql -u root -p  (输入密码进入mysql)

 

2、进入mysql,输入如下命令

use mysql;

 

3、查看user表的情况

SELECT Host,User FROM user;

//指明主机名称,“%”表示匹配所有字符串

 

4、 UPDATE user SET Host = ‘%’ WHERE User= ‘root’ LIMIT 1;

 

5、输入如下命令让刚才设置的命令生效

mysql> flush privileges;

Query OK, 0 rows affected (0.00 sec)

 

 

注意在mysql 命令行形式下一定要输入”;”

 

按照前面五个步骤完成之后,通过控制台输入

[root@linux ~]# mysql -h localhost -u root -p

Enter password:

ERROR 1045 (28000): Access denied for user ‘root’@’localhost’ (using password: YES)

不让这么连接数据库

 

原因:是因为host对应的user字段是空的,我们需要将其改为root即可

mysql> select host,user from user;

+———–+——+

| host      | user |

+———–+——+

| %         | root |

| 127.0.0.1 | root |

| linux     |      |

| linux     | root |

| localhost |      |

+———–+——+

5 rows in set (0.00 sec)

 

解决办法一:

mysql> update user set user=’root’ where host=’localhost’;

Query OK, 1 row affected (0.00 sec)

Rows matched: 1  Changed: 1  Warnings: 0

 

mysql> flush privileges;

Query OK, 0 rows affected (0.00 sec)

 

 

 

解决办法二:

将localhost改为本机的IP地址,则能够识别了

[root@linux ~]# mysql -h 172.16.42.68 -u root -p

Enter password:
