VPS 上的第二个虚拟主机显示“无法连接到服务器”

我使用的是 Debian 7 Wheezy 和 Apache 2.2.22，并且正在 VPS 上为多个网站设置虚拟主机。我已成功为其中一个网站配置 VirtualHost 指令，但第二个网站在 Firefox 中不断显示“加载页面时出现问题”。我已运行并验证了我的所有语法均正确无误，并且我已检查了所有权限。第二个域上的所有内容几乎都是从第一个域复制/粘贴的，因此我不确定问题是什么，因为除了我重新加载配置的位置之外，configtest没有其他条目：/var/log/apache2/error.log

</VirtualHost>

我也尝试过设置 NameVirtualHost 如下：

Listen 80
NameVirtualHost 23.88.121.82:80
NameVirtualHost 127.0.0.1:80

以及 VirtualHost 指令：

<VirtualHost 23.88.121.82:80>
...
</VirtualHost>

对于两个站点来说，但这也会导致第一个站点发生故障。

我想知道是否需要为每个站点设置单独的 IP？我还有 2 个 IPv4 和 3 个 IPv6 地址可用，如果这样会有所不同的话。此外，从总体上讲，我需要为第一个站点启用 SSL。我读到我基本上只需要模仿监听端口 80 的指令，只监听端口 443，并确保 mod_ssl 已启用？

编辑：我刚刚apache2 -t以这种方式测试了配置文件，并收到错误：apache2: bad user name ${APACHE_RUN_USER}。但是，apachectl configtest返回Syntax OK。但是，其他地方没有提到互斥体的错误。我很确定，如果 apache 应该在其下运行的用户出现错误，服务器根本无法启动……

编辑2：重新启动 apache 修复了错误的用户名错误。

答案1

事实证明 DNS 设置存在问题，并且所有 Apache 配置都是正确的。:/
