法律研究如何在 Ubuntu 上設定 Shiny Server
Shiny 是一個 R 包，允許 Linux 使用者將 R 程式碼轉換為互動式網頁並在網上釋出文件。您可以獲取您的 Shiny 應用程式並在您的組織或全球範圍內共享。本文介紹瞭如何在 Ubuntu 上設定 Shiny Server。
在 Ubuntu 上安裝 Shiny Server
在安裝 Shiny Server 之前，我們需要安裝 shiny R 包。要安裝 R 包，請使用以下命令 -
$ sudo apt-get install r-base
示例輸出應如下所示 -

我們將使用 GDebi 工具安裝 Shiny Server。要安裝 GDebi，請使用以下命令 -
$ sudo apt-get install gdebi-core
示例輸出應如下所示 –

要下載 Shiny Server，請使用以下命令 -
$ wget https://download3.rstudio.org/ubuntu-12.04/x86_64/shiny-server-1.4.2.786-amd64.deb
示例輸出應如下所示 –

現在使用 GDebi 安裝使用以下命令下載的檔案 -
$ sudo gdebi shiny-server-1.4.2.786-amd64.deb
示例輸出應如下所示 –

Shiny Server 現在應該已安裝並正在埠 3838 上執行。您應該能夠在 http://your_server_ip:3838/ 上看到預設的歡迎螢幕。示例輸出應如下所示 -
託管互動式 R Markdown 文件
此時，您應該有一個可以託管 Shiny 應用程式的正常執行的 Shiny Server，但它還無法託管互動式 R markdown 文件，因為 rmarkdown R 包尚未安裝。Shiny Server 帶有一個示例互動式文件，可在以下位置獲取
Shiny Server 帶有一個示例互動式文件，可在 http://your_server_ip:3838/sample-apps/rmd/ 獲取。如果您現在轉到該 URL，您將看到一個錯誤。
要解決上述問題，請使用以下命令 -
$ sudo su - -c "R -e \"install.packages('rmarkdown', repos='http://cran.rstudio.com/')\""示例輸出應如下所示 –

現在，Shiny Server 也設定為執行互動式 R markdown 文件以及 Shiny 應用程式。要驗證互動式文件的工作原理，請轉到 http://your_server_ip:3838/sample-apps/rmd/。
您現在擁有一個功能齊全的 Shiny Server，可以託管 Shiny 應用程式或互動式文件。Shiny Server 的配置檔案位於 /etc/shiny-server/shiny-server.conf。預設情況下，它配置為在 /srv/shiny-server/ 目錄中提供服務。這意味著放置在 /srv/shiny-server/app_name 的任何 Shiny 應用程式都可以在 http://your_server_ip:3838/app_name/ 上公開訪問。
閱讀本文後，您將能夠理解 - 如何在 Ubuntu 上設定 Shiny Server。在我們的下一篇文章中，我們將推出更多基於 Linux 的技巧和提示。繼續關注！
