我正在尝试在 Ubuntu 12.04 lts 上设置 apache 虚拟主机。我按照此处的指南进行操作http://www.debian-administration.org/articles/412除了我使用的是 /var/www 而不是 /home/www。我已将文档根文件夹设置为 755 权限。这是我在家里运行的服务器，所以我认为可能是我的路由器出了问题？我没有使用代理。是否需要以某种方式设置端口转发才能运行虚拟主机？（是的，在虚拟主机之前它运行良好。我收到 502 响应错误（网关错误）。这是我启用的两个站点
NameVirtualHost *:80
<VirtualHost *:80>
ServerName www.functioncreate.com
ServerAlias functioncreate.com
# Indexes + Directory Root.
DirectoryIndex index.html
DocumentRoot /var/www/functioncreate/htdocs/
# CGI Directory
ScriptAlias /cgi-bin/ /var/www/functioncreate/cgi-bin/
<Location /cgi-bin>
Options +ExecCGI
</Location>
# Logfiles
ErrorLog /var/www/fucntioncreate/logs/error.log
CustomLog /var/www/functioncreate/logs/access.log combined
</VirtualHost>
第二个：
#
# Example.com (/etc/apache2/sites-available/www.example.com)
#
<VirtualHost *:80>
ServerName www.labelleviemodesto.com
ServerAlias labelleviemodesto.com
# Indexes + Directory Root.
DirectoryIndex index.html
DocumentRoot /var/www/labellevie/htdocs/
# CGI Directory
ScriptAlias /cgi-bin/ /var/www/labellevie/cgi-bin/
<Location /cgi-bin>
Options +ExecCGI
</Location>
# Logfiles
ErrorLog /var/www/labellevie/logs/error.log
CustomLog /var/www/labellevie/logs/access.log combined
</VirtualHost>
我的 httpd.conf 中没有任何内容。我尝试过启用和禁用“默认”站点。我在 apache 中唯一接触过的东西是我在 sites-available 中创建的新站点，然后通过 a2ensite 符号链接到 sites-enabled（随后重新加载 apache），然后在 conf.d 中创建 virtual.conf，其中包含以下内容：
#
# We're running multiple virtual hosts.
#
NameVirtualHost *
这是我的错误日志

我有几点建议：
检查路由器两侧的行为是否存在差异。假设您的服务器的内部 IP 是 192.168.0.10。编辑测试机器上的 hosts 文件（Mac 上的 /etc/hosts 和 Windows 上的 c:\windows\system32\driver\etc\hosts - 记得在 Mac 上使用 sudo 或在 Windows 上“以管理员身份运行”，否则您将无法编辑文件）并向其中添加以下行（将 192.168.0.10 替换为您的实际 IP）内部/家庭网络服务器IP):
192.168.0.10 www.labelleviemodesto.com labelleviemodesto.com
192.168.0.10 www.functioncreate.com functioncreate.com
对所有这些域名执行 ping 操作，以确保您访问的是正确的 IP。nslookup 不起作用，因为它只会查询 DNS，这将为您提供服务器的正确（外部）IP 并忽略主机文件覆盖。Ping 和所有其他程序都将遵守主机文件覆盖。显然，您需要在私人（家庭）网络内部执行此操作，例如在 Wi-Fi 上。如果 ping 针对所有 4 个域的内部 IP（192.168.0.10）（这很重要，因为例如 functioncreate.com 可能会重定向到 www.functioncreate.com 反之亦然，因此您要确保无论如何，您都在直接与内部 IP 通信，中间没有路由器）。
无论如何，最重要的是：看看您是否仍然收到 502 错误。如果收到，那么它很可能来自 Apache，并且您的配置文件有问题。如果它通过私有 IP 正常工作，但当您从外部通过路由器访问此服务器时收到 502 错误，那么问题就出在您的路由器配置上。
我的猜测是：是路由器。您的 Apache 配置中似乎没有任何类似反向代理的东西。
最后说明：确保您只有一个名称虚拟主机在所有 .conf 文件中都添加一行。如果你有多个，或者你的虚拟主机参数与您的不完全对应名称虚拟主机参数，您将得到奇怪的、意想不到的结果。例如，由于您已经定义了所有虚拟主机，如下所示：
VirtualHost *:80
确保所有 Apache 配置文件中唯一的 NameVirtualHost 行如下所示：
NameVirtualHost *:80
您不应该在日志中看到这样的行！
[Wed Feb 12 23:46:06 2014] [warn] NameVirtualHost *:80 has no VirtualHosts
当然，这不是一个直接的答案，但我希望它能让你更接近答案。:)
