关于shiny 服务器配置，虽然默认根目录下的/srv的shiny-server目录，端口是3838

server {
  listen 3838;location / {

    site_dir /srv/shiny-server;

log_dir /var/log/shiny-server;directory_index on;
  }
}

可以设置多个端口监听

server {
  listen 4949;location / {

    site_dir /srv/shiny-server;

log_dir /var/log/shiny-server;directory_index on; } }

因为我们是以shiny这个用户来运行这些shiny的web app的，所以要给予一定的目录一些适当的权限给shiny用户。

首先是需要写的目录

• /var/lib/shiny-server/ (or whatever custom SHINY_DATA_DIR setting you're using)
• /var/log/shiny-server/ (and/or whatever other directories you use for logging)

然后是需要读取的目录

• /srv/shiny-server/ (and/or whatever other directories you're using to host Shiny applications)
• /opt/shiny-server/
• /etc/shiny-server/ (Note that you should enable only read access on this directory, as you likely don't want to allow your Shiny applications (which also run as shiny) to be able to write to your configuration or password file.)

还有，如果/tmp/shiny-server/目录存在的话，也需要设置好相应的权限。

然后就可以把shiny官网的例子克隆到自己的服务器里面，开始在shiny的世界里面遨游啦！

收费版本还有很多其它功能:

The app_session_timeout setting can be used to automatically disconnect idle Shiny connections.

Shiny Server is capable of automatically inserting the necessary JavaScript code to enable Google Analytics tracking globally or for a particular server or location.

Memory limits will be added in a coming version of Shiny Server Professional.

Shiny Server can use a wide variety of techniques to keep the data in the web browser synchronized. The preferred technique, and the one most widely used, is the use of WebSockets.

Shiny Server Professional offers the ability to authenticate individual users. By specifying authentication requirements on particular servers or locations, the administrator can control the set of applications particular users are allowed to access.( session$user  和 session$groups)

Regardless of which authentication mechanism is used, the duration of authentication can be configured using the auth_duration setting.

Shiny Server Pro supports the ability to rely on Google for the management of your users using the auth_google setting.

In Shiny Server Professional, SSL encryption is available for any configured server and in the admin interface. SSL is a means of encrypting traffic between web clients and servers and should be used for any application that will accept or transmit sensitive information such as passwords.
