Question

我在使用nginx的DigitalOcean Ubuntu 14.04.5 Droplet上托管了flash-server。

Shiny服务器工作正常，但在重新启动Droplet以调整配置大小后停止工作。这个问题早些时候没有发生过。

我尝试使用start: Job failed to start重启启动服务器，但我获得状态/srv/shiny-server/。

当我访问

shiny-server.pid处没有/var/run/shiny-server/。

我的/etc/shiny-server/shiny-server.conf设置：



    # 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;
      }
    }

我不确定问题是什么。尝试搜索在线论坛，但没有运气！请帮忙。谢谢！
