[英]Launch shiny application on server
I am trying to launch shiny application on server. 我正在尝试在服务器上启动闪亮的应用程序。 I just followed instruction from Administering guide:
我只是按照《管理指南》中的说明进行操作:
mkdir ~/ShinyApps
sudo cp -R /opt/shiny-server/samples/sample-apps/hello ~/ShinyApps/
Then tried to access the hello application through http://<server-address>:3838/<your_username>/hello
But it shows this page can't be displayed error. 然后尝试通过
http://<server-address>:3838/<your_username>/hello
访问hello应用程序,但它显示此页面无法显示错误。 Anyone has any idea about what can cause this problem? 任何人都知道什么会导致此问题? Thanks!
谢谢!
Cont. 续 Thanks Jeff, I used the exact same part in guide.
谢谢杰夫,我在指南中使用了完全相同的部分。 Here is the shiny-server.conf file:
这是shiny-server.conf文件:
server {
listen 3838;
# Define a location at the base URL
location /users {
#this is set up so that I can run apps sithout sudo
run_as :HOME_USER:
user_dirs;
}
location /apps {
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;
}
}
shiny-server.log shows lots of error: Shiny-server.log显示很多错误:
[32m[2014-04-28 11:04:42.871] [INFO] shiny-server - [39mShiny Server v1.1.0.10000 (Node.js v0.10.21)

How can I fix those those error? 我该如何解决这些错误?
I assume you got that command from this portion of the guide? 我假设您从指南的这一部分得到了该命令? If so, did you also use the
deploy-example
script to change your configuration file? 如果是这样,您是否还使用
deploy-example
脚本来更改配置文件? Did you get any errors when you ran that script? 运行该脚本时是否遇到任何错误?
Alternatively, edit your question to include your configuration file at /etc/shiny-server/shiny-server.conf
and we'll be able to see if your server is properly configured to use user_dirs
which would be needed for users to be able to host their own applications. 或者,编辑您的问题以在
/etc/shiny-server/shiny-server.conf
包含您的配置文件,我们将能够查看您的服务器是否已正确配置为使用user_dirs
,这对于用户来说是必需的。托管自己的应用程序。
Also check for (and/or edit your question to include) any recent entries in the server's log at /var/log/shiny-server.log
. 还要在服务器日志中
/var/log/shiny-server.log
检查(和/或编辑您的问题以包括)最近的条目。
Try the URL http://<server-address>:4949/sample-apps/
. 尝试使用URL
http://<server-address>:4949/sample-apps/
。 If not 4949, try 3838. 如果不是4949,请尝试3838。
The reason is whether the port 3838
is open. 原因是
port 3838
是否打开。 If it's not open, maybe you should run the following directives in your server: 如果未打开,则可能应在服务器中运行以下指令:
iptables -I INPUT -p tcp --dport 3838 -j ACCEPT
iptables -I INPUT -p gre -j ACCEPT
