无法连接到数据库：拒绝访问用户“@ @ localhost”到数据库'socialdb' [英] Unable to connect to database: Access denied for user ''@'localhost' to database 'socialdb'

问题描述

我看到这样的错误，但我没有找到答案。

I've seen a few errors like this, but I found no answer.

Unable to connect to database: Access denied for user ''@'localhost' to database 'socialdb'

socialdb是我的数据库。 无法连接到数据库：部分位于此处。

socialdb is my database. The "Unable to connect to database:" part is located here.

$db = mysql_select_db("socialdb",$con);

if(!$db) {

    die ('Unable to connect to database: ' . mysql_error());

    }

我不知道是什么原因造成的。这是我的mysql_connect详情

I don't know what's causing this. Here are my mysql_connect details

<?php
$con = mysql_connect("localhost");

if(!$con) {

    die ('Error: ' . mysql_error());

    }

我需要找到根。非常感谢。

I need to find the root. Thanks.

我没有MySQL用户名或密码

I DON'T HAVE A USERNAME OR PASSWORD FOR MySQL

p>

Should it be this?

mysql_connect("localhost","","");

推荐答案

错误是不言自明的，不允许连接而不指定一些凭据。

The error is pretty self-explanatory, you're not allowed to connect without specifying some credentials.

将您的通话更改为 mysql_connect（） 如下：

Change your call to mysql_connect() to something like this:

mysql_connect("localhost", "user", "password");
