Question

错误是1045.但我的用户名和密码是正确的。

我从192.168.0.18连接到fcapdi（到192.168.0.240:3306）

我的用户表

 MariaDB [(none)]> SELECT User,Host FROM mysql.user;
 +--------+-----------+
 | User   | Host      |
 +--------+-----------+
 | dba    | %         |
 | fcapdi | %         |
 | root   | 127.0.0.1 |
 | root   | ::1       |
 |        | localhost |
 | root   | localhost |
 |        | tester    |
 | root   | tester    |
 +--------+-----------+

当我使用我收到的root帐户使用phpMyAdmin登录时

＃1045 - 用户'root'@'localhost'拒绝访问（使用密码：YES）

但是我的帐号dba可以正常登录。发生了什么事？

另外我想我应该注意到MySQL实例位于具有2个NIC的服务器上，并且位于2个（内部）网络上。一个是本地域192.168.0/24，另一个是更大的域10.228./16。

我可以通过10.228./16网络中的fcapdi帐户登录。但不是来自192.168.0./24网络。

Answer 1

执行：

GRANT ALL ON 
    your_database_schema_name.* to 
    'fcapdi'@'192.168.0.18' IDENTIFIED BY 'your_connection_password';

作为服务器上具有GRANT权限的用户并尝试连接。

As an aside question under comments

SET PASSWORD FOR 'root'@'localhost' = PASSWORD('newPass123^'); 
SET PASSWORD FOR 'root'@'127.0.0.1' = PASSWORD('newPass123^'); 
SET PASSWORD FOR 'root'@'etc_etc' = PASSWORD('newPass123^'); 

you can also do it in a single update statement but it depends on your mysql version

create user 'joe1'@'localhost' identified by 'blah';
create user 'joe1'@'127.0.0.1' identified by 'afadfafsdblah2';
create user 'joe1'@'%' identified by 'djdjdjjdjdd';;


select user,host,password from mysql.user where user='joe1';
+------+-----------+-------------------------------------------+
| user | host      | password                                  |
+------+-----------+-------------------------------------------+
| joe1 | localhost | *0380BEA27363E56C37F0BFDA438F429080848051 |
| joe1 | %         | *7BEAF25E9BDFBDEF5A9B9E4A37023721B668FA51 |
| joe1 | 127.0.0.1 | *5CD978E569B31B1558E5C1D0972E6E02516893BF |
+------+-----------+-------------------------------------------+

update mysql.user set password=PASSWORD('nEW_COMMon_password762') where user='joe1';
-- 3 rows updated

select user,host,password from mysql.user where user='joe1';
+------+-----------+-------------------------------------------+
| user | host      | password                                  |
+------+-----------+-------------------------------------------+
| joe1 | localhost | *A248B352CE5BF750A11AA9BA253B5F191C721D1A |
| joe1 | %         | *A248B352CE5BF750A11AA9BA253B5F191C721D1A |
| joe1 | 127.0.0.1 | *A248B352CE5BF750A11AA9BA253B5F191C721D1A |
+------+-----------+-------------------------------------------+

对于Mysql 5.7，不是名为password的列。而是针对authentication_string

清理：

drop user 'joe1'@'%';
drop user 'joe1'@'127.0.0.1';
drop user 'joe1'@'localhost';
