构建 rShiny 应用程序后,我想在我自己的服务器上在线托管它。
我目前有一台带有 Ubuntu(最新版本)的服务器,我想在 Docker、Shinyproxy 和 nginx 的帮助下运行托管。
我已经创建了 Docker 映像并在“sudo docker run ....”的帮助下成功执行了它——这里一切正常。不幸的是,通过 ShinyProxy 托管不起作用。所以错误一定是(我认为)我的 ShinyProxy 文件(application.yml)或 nginx(默认,默认)。
当我调用 URL 时,我收到以下错误消息:(请参阅问题末尾的完整日志)
错误状态码:500 消息:容器未及时响应
我的 ShinyApp 通常由以下组件组成:Funktionen.R、Inputs.R、install_packages.R、Server.R、ui.R
我试图检查所有端口、设置和所有内容,但它不起作用。
我希望您找到分析以下错误所需的一切,并希望找到解决方案!非常感谢!
如果您需要更多信息,请告诉我!
