【问题描述】：

现在当我尝试转到“domain.com/admin”时出现此错误

A Database Error Occurred

Unable to connect to your database server using the provided settings.

Filename: core/Loader.php

Line Number: 346

我也应该能够使用"domain.com/phpmyadmin" 之类的域来使用phpmyadmin，但不能使用新IP。

我做什么：

安装相同的 Xampp 并配置安全性。

使用 WinSCP 将文件从旧 VPS 复制到新 VPS。

/opt/lampp/domain.com
编辑/opt/lampp/etc/httpd.conf

Include etc/extra/httpd-vhosts.conf
编辑/opt/lampp/etc/extra/httpd-vhosts.conf

<VirtualHost *:80> DocumentRoot "/opt/lampp/domain.com/" ServerName dotaskapp.com </VirtualHost>
编辑/opt/lampp/etc/extra/httpd-xampp.conf

<Directory "/opt/lampp/domain.com/">> AllowOverride All Order allow,deny allow from all Require all granted ErrorDocument 403 /error/XAMPP_FORBIDDEN.html.var </Directory> <Directory "/opt/lampp/phpmyadmin"> AllowOverride AuthConfig Limit Require local Require ip myip ErrorDocument 403 /error/XAMPP_FORBIDDEN.html.var </Directory> <Directory "/opt/lampp/phpsqliteadmin"> AllowOverride AuthConfig Limit Require local Require ip myip ErrorDocument 403 /error/XAMPP_FORBIDDEN.html.var </Directory>
在浏览器中：http://vpsIp/phpmyadmin/ 并导入数据库。
编辑 /etc/hosts

127.0.0.1 domain.com
重启xampp。

/opt/lampp/lampp restart

将域名服务器IP更改为新的VPS IP。

【问题讨论】：

不工作如何？在您解释什么不起作用之前，以上所有内容都是无用的？
1.这更多是与运营相关的问题，而不是与软件开发相关的问题。系统管理员可以更好地提供答案。 2. 没有实际的错误信息，我们只能猜测可能出了什么问题。
这取决于您的主域是否有效，但您的子 URL 有问题，例如 /admin，如果您得到 404，则可能是 apache 重写模块。如果是 403 则可以是文件和文件夹权限（也取决于项目）
现在我收到一个错误，问题出在域名服务器上。

标签： php apache ubuntu xampp

【解决方案1】：

为了解决域名问题，我更改了域名服务器，因为我的新 VPS 只接受他们自己的域名服务器。

“无法使用提供的设置连接到您的数据库服务器”的问题。

已修复在 phpMyAdmin 中添加具有相同凭据的新用户。
