更新Shiny Server Config以更改超时错误 [英] Updating Shiny Server Config to change timeout error

问题描述

我有一个内置了 downloadHandler 的闪亮应用程序，它适用于较小的数据集，但是当文件很大(330 MB)时，它就会超时并且出现错误.

I have a shiny app with a downloadHandler built in and it works great for smaller datasets but when the file gets large (330 MB), it times out and I get an error.

我发现了这个问题( shiny downloadHandler timeout )，尽管我没有回答，但似乎可以解决问题不知道如何更新配置文件以考虑 http_keepalive_timeout .

I found this SO question (shiny downloadHandler timeout) which seems to address the answer although I don't know how to update the config file to take into account http_keepalive_timeout.

以下是我的配置文件:

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


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

  # Define a location at the base URL
  location / {

    # 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;

  }
}

我将 http_keepalive_timeout 函数放在错误的位置.请参见下面的正确的 shiny-server.conf 更新:

I was putting the http_keepalive_timeout function in the wrong place. Please see below for the correct shiny-server.conf update:

# Instruct Shiny Server to run applications as the user "shiny"
run_as shiny;
http_keepalive_timeout 180;

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

  # Define a location at the base URL
  location / {

    # 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;

  }
}
