Apache2 - 如果找不到页面，则从另一个域提供服务

我遇到了主主机 IP 和所服务的虚拟主机的奇怪行为，基本上我有以下情况：

|- 148.x.x.x            /var/www/html/public_html
|- domain01.com         /var/www/html/domain01.com/public_html
|- domain02.com         /var/www/html/domain02.com/public_html
|- domain03.com         /var/www/html/domain03.com/public_html

问题 01：现在如果我访问 148.xxx 上的任何页面，我都会获得404http 代码，并且如果托管相同的页面名称，domain01.com则会显示其内容。

问题 02：如果在其他域中找不到任何页面，并且恰巧托管了相同的页面名称，domain01那么它将被提供服务。我的 httpd.conf：

答案1

如果不知道主机名的具体含义，就很难确定这到底是 DNS 注册问题还是服务器配置问题，但您可以在配置中进行几项更新，这可能有助于解决问题，或者至少，如果问题确实与 DNS 有关，则可以防止将来出现此类问题。

在虚拟主机文件上，您需要确保具有：

<VirtualHost *:80>
    ServerName domain01.com
    ServerAlias www.domain01.com
    ServerAdmin [email protected]
    DirectoryIndex index.html
    DocumentRoot /var/www/html/domain01/public_html
    LogLevel warn
    ErrorLog /var/log/httpd/domain01-error.log
    CustomLog /var/log/httpd/domain01-access.log combined

    <Directory "/var/www/html/domain01/public_html">
        Options -Indexes +FollowSymLinks
        AllowOverride All
    </Directory>
</VirtualHost>

如果您没有将目录正确地括在引号中作为字符串，则您会缺少 TLD domain01，并且您会将ServerName和ServerAlias条目作为相同的对象提供，但没有 TLD。

忘了提： 具有 IP 的虚拟主机通常按如下方式提供服务：

<VirtualHost 148.X.X.X>
  DocumentRoot /wwwdomain01
  ServerName www.domain01.com
</VirtualHost>

<VirtualHost 148.X.X.X>
  DocumentRoot /wwwdomain02
  ServerName www.domain02.com
</VirtualHost>

这是个很棒的资源

如果你不想使用显式 IP，那么你始终可以listen按照说明使用Apache 文档这里：听， 和这里：虚拟主机

答案2

这是因为虚拟主机正在监听 *。这意味着为服务器配置的任何 IP 地址（第一个配置的 IP 地址通常是响应的 IP 地址）都可以处理请求。您需要使用该虚拟主机专用的 IP 地址。
