1 安装
环境:centos6.5
- 1.1 安装R
$ sudo yum install R
- 1.2 进入R,安装包shiny,rmarkdown
install.packages('shiny')
install.packages('rmarkdown')
- 1.3 安装shiny-server
$ wget https://download3.rstudio.org/centos5.9/x86_64/shiny-server-1.4.2.786-rh5-x86_64.rpm
$ sudo yum install --nogpgcheck shiny-server-1.4.2.786-rh5-x86_64.rpm
查看是否安装成功:进入ip:3838
##2 启动
start shiny-server
stop shiny-server
status shiny-server
reload shiny-server
##3 配置
- 3.1 默认配置
cat /etc/shiny-server/shiny-server.conf
首页:/srv/shiny-server/index.html shiny app 的目录:/srv/shiny-server/sample-apps 详细配置参数见:shiny-server conf settings
##4 注意问题
- 4.1 The application took too long to respond.
修改/etc/shiny-server/shiny-server.conf中的参数增加延时
$ vi /etc/shiny-server/shiny-server.conf
app init timeout 300;
app idle timeout 300;
- 4.2 linux文件建立连接(软连接、硬链接)
建立文件夹软连接
ln -s /home/xuwy/flow_model /srv/shiny-server/app_flow
删除
rm -rf /home/xuwy/flow_model
注意不可按照以下方式删除(会直接删除对应原文件的子目录下所有文件)
rm -rf /home/xuwy/flow_model/
- 4.3 HTML的图片插入相对路径
与index.html相同路径的直接使用
<img src="mac_heatmap_gg.gif" alt="mac View" style="width:1104px;height:528px;">
子目录下的使用方法
<img src="/images/mac_heatmap_gg.gif" alt="mac View" style="width:1104px;height:528px;">
- 4.4 shiny project中有load(./xx.RData)
xx.RData会间隔时间变化,但是shiny-server不会实时更新,只能采取间隔时间重启shiny-server服务
restart shiny-server
备注 将shiny project 或者 rmarkdown嵌入到html
<div id="shiny">
<iframe src="./sample-apps/hello/" style="border: 1px solid #AAA; width: 290px; height: 460px"></iframe>
<div class="caption">
When Shiny is properly configured on your server, you'll see a Shiny app above.
</div>
<iframe src="./sample-apps/rmd/" style="border: 1px solid #AAA; width: 290px; height: 420px"></iframe>
<div class="caption">
With Shiny and <code>rmarkdown</code> installed, you should see a Shiny doc above.
