Apache VirtualHost 設置… 502 Bad Gateway
我正在嘗試在 Ubuntu 12.04 lts 上設置 apache 虛擬主機。我在這裡遵循了本指南http://www.debian-administration.org/articles/412 ，但我使用的是 /var/www 而不是 /home/www。我已將文件根文件夾設置為 755 權限。這是我家的伺服器，所以我認為這可能是我的路由器有問題嗎？我沒有使用代理。是否需要設置某種方式的埠轉發來執行虛擬主機？（是的，它在虛擬主機之前執行良好。我收到 502 響應錯誤（網關錯誤）。這是我啟用的兩個站點
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>第二個：
# # 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 裡面什麼都沒有。我嘗試過啟用和禁用“預設”站點。我在 apache 中唯一接觸過的東西是我在 sites-available 中創建的新站點，然後通過 a2ensite 符號連結到啟用的站點（然後是 apache 重新載入），然後在 conf.d 中創建 virtual.conf ，其中包含以下內容：

我有幾個提示：
檢查路由器兩側的行為是否存在差異。假設您的伺服器的內部 IP 是 192.168.0.10。編輯您的測試機器上的主機文件（Mac 上的 /etc/hosts 和 Windows 上的 c:\windows\system32\driver\etc\hosts - 記住在 Mac 上使用 sudo 或在 Windows 上“以管理員身份執行”，否則你不會無法編輯文件）並向其中添加以下行（將 192.168.0.10 替換為您的實際內部/家庭網路伺服器 IP）：
192.168.0.10 www.labelleviemodesto.com labelleviemodesto.com 192.168.0.10 www.functioncreate.com functioncreate.comping 所有這些域名以確保您訪問正確的 IP。nslookup 不起作用，因為它只會查詢 DNS，這將為您提供伺服器的正確（外部）IP 並忽略主機文件覆蓋。Ping 和所有其他程序將尊重主機文件覆蓋。顯然，您需要在您的私人（家庭）網路內部執行此操作，例如在 wi-fi 上。如果 ping 以所有 4 個域的內部 IP (192.168.0.10) 為目標（這很重要，因為例如 functioncreate.com 可能會重定向到 www.functioncreate.com，反之亦然，因此您要確保無論什麼，您直接與內部 IP 通話，中間沒有路由器）。
無論如何，底線：看看你是否仍然得到 502 錯誤。如果你這樣做了，那麼它很可能來自 Apache，並且你的配置文件有問題。如果通過私有 IP 可以正常工作，但是當您從外部通過路由器訪問此伺服器時，您會收到 502 錯誤，那麼問題出在您的路由器配置上。
我的猜測：這是路由器。您的 Apache 配置中似乎沒有任何類似反向代理的東西。
最後說明：確保在所有 .conf 文件中只有一個且只有一個NameVirtualHost行。如果您有多個，或者如果您的VirtualHost參數與您的****NameVirtualHost參數不完全對應，您將得到奇怪的、意想不到的結果。例如，由於您已經定義了所有虛擬主機，如下所示：
VirtualHost *:80確保所有 Apache 配置文件中唯一的 NameVirtualHost 行如下所示：
NameVirtualHost *:80您不應該在日誌中看到這樣的行！
[Wed Feb 12 23:46:06 2014] [warn] NameVirtualHost *:80 has no VirtualHosts當然，這不是一個直接的答案，但我希望它能讓你更接近答案。:)
