结合实际的工作环境，在开始R研究的时候，首先着手收集的就是能以Web方式发布R运行结果的基础框架，无耐的是，R一直以来常使用于个人电脑的客户端程序上，大家习惯性的下载R安装包，在自己的电脑上安装 --> 写算法 --> 运行 --> 以贴图或者文档的形式发表自己的作品。幸运的最终找着了一套这样的框架FastRWeb (Fast Interactive Web Framework for Data Mining Using R），参考 （http://www.rforge.net/FastRWeb/），FastRWeb 是一个基础架构环境, 可以让R脚本运行在任何WebServer上，展示数据和图形，用户通过URL地址与R脚本进行通信交互。
目录：
运行架构原理：
Centos7 R3.2.5软件包安装:
yum install -y gcc
yum install -y gcc-c++
yum install -y gcc-gfortran
yum install -y readline-devel
yum install -y libXt-devel
yum install –y libcur*
yum install –y libxml*
yum install –y openssl*
将下载到本机的R安装包软件上传文件至linux主机的某目录下, 执行解压命令：tar -zxvf R-3.2.5.tar.gz
R is now configured for x86_64-pc-linux-gnu Source directory: . Installation directory: /home/work/R C compiler: gcc -std=gnu99 -g -O2 Fortran 77 compiler: gfortran -g -O2 C++ compiler: g++ -g -O2 C++ 11 compiler: g++ -std=c++11 -g -O2 Fortran 90/95 compiler: gfortran -g -O2 Obj-C compiler: Interfaces supported: X11 External libraries: readline Additional capabilities: NLS Options enabled: shared R library, shared BLAS, R profiling Capabilities skipped: PNG, JPEG, TIFF, cairo, ICU Options not enabled: memory profiling Recommended packages: yes configure: WARNING: you cannot build info or HTML versions of the R manuals configure: WARNING: you cannot build PDF versions of the R manuals configure: WARNING: you cannot build PDF versions of vignettes and help pages [root@R R-3.2.5]#
PATH=/home/work/R/bin:$PATH
RStudio 安装配置：
systemctl status rstudio-server
systemctl start rstudio-server
systemctl stop rstudio-server
systemctl restart rstudio-server
执行下面的命令清单，给RStudio添加操作用户和权限
adduser rstudio
passwd rstudio
usermod -g rstudio-server rstudio
命令：systemctl start rstudio-server (启动rstudio-server 服务，默认监听端口 8787）
FastRWeb安装：
g++ Rconnection.o Rcgi.o -o Rcgi -lcrypt make[1]: Leaving directory `/tmp/RtmpdpC13f/R.INSTALL53b568210efe/FastRWeb/src/Rcgi‘ rm -rf ../inst/Rcgi cp -r Rcgi ../inst mkdir ../inst/cgi-bin touch null.so null.dll # to make R CMD SHLIB happy installing to /home/work/R/lib64/R/library/FastRWeb/libs ** R ** inst ** preparing package for lazy loading ** help *** installing help indices ** building package indices ** testing if installed package can be loaded * DONE (FastRWeb) The downloaded source packages are in ‘/tmp/RtmpkNJBem/downloaded_packages’ Updating HTML index of packages in ‘.Library‘ Making ‘packages.html‘ ... done >
R命令：install.packages("Rserve")
./mergefat Rserve "/home/work/R/lib64/R/bin/Rserve" ./mergefat Rserve.dbg "/home/work/R/lib64/R/bin/Rserve.dbg" installing via ‘install.libs.R‘ to /home/work/R/lib64/R/library/Rserve ** R ** inst ** preparing package for lazy loading ** help *** installing help indices ** building package indices ** testing if installed package can be loaded * DONE (Rserve) The downloaded source packages are in ‘/tmp/RtmpkNJBem/downloaded_packages’ Updating HTML index of packages in ‘.Library‘ Making ‘packages.html‘ ... done >
R命令： q() (退出R命令行，返回linux命令行）
http.port 8888 remote enable source /var/FastRWeb/code/rserve.R control enable
修改文件：rserve.R, 在文件上的最上面增加2行代码，如下
library(FastRWeb)
.http.request <- FastRWeb:::.http.request
命令： ./start （开启服务，注意：必须切换至 /var/FastRWeb/code 目录下执行）
开发Demo: hello world
run <- function(...){ oprint("hello world") done() }
如果是本地环境开发的，将保存的Demo.R 文件上传至 /var/FastRWeb/web.R 目录下
