无法启动Shiny服务器

Question

我已经在带有nginx的DigitalOcean Ubuntu14.04.5 droplet上托管了shiny-server。

闪亮的服务器工作得很好，但在我重新启动droplet以调整配置大小后停止了工作。这个问题之前没有发生过。

我尝试使用sudo start shiny-server重新启动shiny-server，但得到状态start: Job failed to start。

当我访问托管在/srv/shiny-server/上的闪亮的应用程序时，我得到以下nginx错误。

An error occurred.

If you are the system administrator of this resource then you should check the error log for details.

Faithfully yours, nginx.




Shiny-server error log:

There is no shiny-server.pid at /var/run/shiny-server/.

My /etc/shiny-server/shiny-server.conf settings: 



    # Instruct Shiny Server to run applications as the user "shiny"
    run_as shiny;
    sanitize_errors off;

    # Define a server that listens on port 3838
    server {
      listen 3838;

      # Define a location at the base URL
      location / {

        run_as shiny;

        # Host the directory of Shiny Apps stored in this directory
        site_dir /srv/shiny-server;

        # Log all Shiny output to files in this directory
        log_dir /var/log/shiny-server;

        # When a user visits the base URL rather than a particular application,
        # an index of the applications available in this directory will be shown.
        directory_index on;
      }
    }



I'm not sure what the problem is. Tried searching online forums too but with no luck! Please help. Thanks!

创建一个文件夹sudo mkdir /var/run/shiny-server，然后为Shiny用户sudo chown shiny:shiny /var/run/shiny-server/启用写权限
