1. 安装R
默认的CentOS源中是没有R软件的，需要安装epel源，我们之前已经安装了，R软件在里面的名字为R.x86_64。
$yum install -y R.x86_64
## $ yum list |grep ^R
R.x86_64 3.6.0-1.el7 @epel
R-core.x86_64 3.6.0-1.el7 @epel
R-core-devel.x86_64 3.6.0-1.el7 @epel
R-devel.x86_64 3.6.0-1.el7 @epel
R-java.x86_64 3.6.0-1.el7 @epel
R-java-devel.x86_64 3.6.0-1.el7 @epel
R-RInside.x86_64 0.2.16-1.el7 epel
R-RInside-devel.x86_64 0.2.16-1.el7 epel
R-RInside-examples.x86_64 0.2.16-1.el7 epel
R-RUnit.noarch 0.4.32-1.el7 epel
R-Rcpp.x86_64 1.0.5-1.el7 epel
R-Rcpp-devel.x86_64 1.0.5-1.el7 epel
R-Rcpp-examples.x86_64 1.0.5-1.el7 epel
R-highlight.x86_64 0.5.0-1.el7 epel
R-inline.noarch 0.3.16-1.el7 epel
R-littler.x86_64 0.3.12-1.el7 epel
R-littler-examples.x86_64 0.3.12-1.el7 epel
R-qtl.x86_64 1.46.2-1.el7 epel
R-rlecuyer.x86_64 0.3.4-1.el7 epel
R2spec.noarch 4.2.1-1.el7 epel
RBTools.noarch 1.0.3-1.el7 epel
RabbIT.noarch 4.1-13.el7 epel
RackTables.noarch 0.20.14-1.el7 epel
RdRand.x86_64 2.1.2-2.el7 epel
RdRand-devel.x86_64 2.1.2-2.el7 epel
ReviewBoard.noarch 2.5.17-1.el7 epel
2.安装Rstudio-server（安装这个可以用网页访问）
下载最新版Rstudio-server
https://www.rstudio.com/products/rstudio/download-server/
wget https://download2.rstudio.org/server/centos6/x86_64/rstudio-server-rhel-1.2.1335-x86_64.rpm
yum install -y rstudio-server-rhel-1.2.1335-x86_64.rpm
3.开启8787端口
+++记得要在root下+++
systemctl enable rstudio-server.service
systemctl start rstudio-server.service
systemctl status rstudio-server
firewalld
firewall-cmd --permanent --add-port=8787/tcp
firewall-cmd --permanent --add-port=8787/udp
firewall-cmd --reload
这样就完成了R与Rstudio-server的安装，通过IP地址加端口好就可以访问了。例如8.8.8.8:8787
