我試圖透過讓 Apache 反向代理電腦上的其他 HTTP 伺服器來繞過 Chrome 中的 ERR_UNSAFE_PORT 限制。
- 我載入 mod_proxy
sudo e2enmod proxy - 我添加
ProxyPass /znc/ http://localhost:6667/到我的httpd.conf - 我重新啟動 Apache
sudo /etc/init.d/apache2 restart
當我打開時/znc/，我收到 500 內部伺服器錯誤。我添加了LogLevel debug，重新啟動apache，再次嘗試，沒有發現任何可疑的地方：

所以我現在很困惑。怎麼辦？
我正在運行 Ubuntu 伺服器 11.10。當直接從本機電腦和 Internet 查詢時，ZNC 會以正確的 200 OK 和 HTML 進行回應。
答案1
也必須啟用 mod_proxy_http 與sudo a2enmod proxy_http.
