前言

原本我是不想写的，但是考虑到后续自己可能还会用到，还是记录一下吧。安装过程很简单就是添加源、装依赖、拉包并安装。
可以参考rstudio的安装方法：https://www.liujason.com/article/121.html
这次是在CentOS7的LXC中进行安装，为了做这个东西：https://r-shiny.liujason.com/sea-lungcancer/

ShinyServer安装实例

首先是添加源，要注意sudo有可能没有安装，先装一下

yum install sudo -y && sudo yum install epel-release -y

然后装依赖，wget、R、shiny包等等

sudo yum update

sudo yum install wget R -y

sudo su - \

-c "R -e \"install.packages('shiny', repos='https://cran.rstudio.com/')\""

最后装shinyserver，最新版本自己去官网找

wget https://download3.rstudio.org/centos6.3/x86_64/shiny-server-1.5.12.933-x86_64.rpm

sudo yum install --nogpgcheck shiny-server-1.5.12.933-x86_64.rpm

配置实例

首先看看是否启动成功了，若未成功对照看看是不是依赖包没装好

[root@r-shiny-1 shiny-server]# service shiny-server status

Redirecting to /bin/systemctl status shiny-server.service

● shiny-server.service - ShinyServer

   Loaded: loaded (/etc/systemd/system/shiny-server.service; enabled; vendor preset: disabled)

   Active: active (running) since Sun 2020-01-12 13:52:50 UTC; 17min ago

 Main PID: 19736 (shiny-server)

   CGroup: /system.slice/shiny-server.service

           └─19736 /opt/shiny-server/ext/node/bin/shiny-server /opt/shiny-server/lib/main.js

Jan 12 13:52:50 r-shiny-1 systemd[1]: Started ShinyServer.

然后看看是否正在监听正确的端口和ip

sudo yum install lsof -y

这里我发现机器自动监听的是ipv6，所以需要改一下设置

[root@r-shiny-1 shiny-server]# lsof -i:3838

COMMAND     PID USER   FD   TYPE   DEVICE SIZE/OFF NODE NAME

shiny-ser 19736 root   18u  IPv6 51374060      0t0  TCP *:sos (LISTEN)

设置文件在/etc/shiny-server/shiny-server.conf，所以编辑一下

vi /etc/shiny-server/shiny-server.conf

-------

# Define a server that listens on port 3838

server {

  listen 3838 0.0.0.0;

-------

在server中监听端口后面加上监听的网卡ip，一般用0.0.0.0表示所有ipv4都监听，然后重启rshinyserver

[root@r-shiny-1 shiny-server]# service shiny-server restart

Redirecting to /bin/systemctl restart shiny-server.service

[root@r-shiny-1 shiny-server]# service shiny-server status

Redirecting to /bin/systemctl status shiny-server.service

● shiny-server.service - ShinyServer

访问http://ip:3838/index.html已经可以看到示例页面了。

调用并部署git内的shinyapp

shiny的web根目录在/srv/shiny-server里面，因此先进去删掉所有自带内容，再git拉取就可以了

cd /srv/shiny-server

rm -rf *

git init

git remote add origin https://rcoding.net/liujason/r-shiny-demo-server.git

git pull origin master

完成了，记得装app里面用到的包！

Nginx反代

如果和我一样不想占用整个ip又想使用80/443端口访问的话需要设置nginx反代。要注意的是由于shiny用了Websocket传递图像，因此需要在nginx中做特殊设置，直接贴代码吧：

server

{

    listen 80;

        listen 443 ssl http2;

        ssl_certificate /etc/ssl/cert.crt;

        ssl_certificate_key /etc/ssl/cert.key;

    server_name r-shiny.liujason.com;

        #PROXY-START/

        location /

        {

                expires 12h;

                if ($request_uri ~* "(php|jsp|cgi|asp|aspx)")

                {

                         expires 0;

                }

                proxy_pass http://172.21.0.245:3838;

                proxy_set_header Host $host;

                proxy_set_header X-Real-IP $remote_addr;

                proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

                proxy_set_header REMOTE-HOST $remote_addr;

                proxy_http_version 1.1;

                proxy_set_header Upgrade $http_upgrade;

                proxy_set_header Connection "upgrade";

                add_header X-Cache $upstream_cache_status;

                add_header Cache-Control no-cache;

        }

}
