RHEL6.5（Red Hat Enterprise Linux）全新安装R

公司服务器才用了RHEL操作系统，虚拟机上也安装了一个相同版本，用于相关工作的研究。

1，安装R首先配置yum

RHEL的yum是需要收费的，所以需要删除预安装的服务，重新配置：

删除：rpm -aq|grep yum|xargs rpm -e --nodeps 

下载 ：wget http://mirrors.163.com/centos/6/os/x86_64/Packages/yum-3.2.29-81.el6.centos.noarch.rpm
wget http://mirrors.163.com/centos/6/os/x86_64/Packages/yum-metadata-parser-1.1.2-16.el6.x86_64.rpm
wget http://mirrors.163.com/centos/6/os/x86_64/Packages/yum-plugin-fastestmirror-1.1.30-40.el6.noarch.rpm
wget http://mirrors.163.com/centos/6/os/x86_64/Packages/python-iniparse-0.3.1-2.1.el6.noarch.rpm  
wget http://mirrors.163.com/centos/6/os/x86_64/Packages/python-urlgrabber-3.9.1-11.el6.noarch.rpm 

安装：

rpm -ivh python-iniparse-0.3.1-2.1.el6.noarch.rpm
rpm -ivh yum-metadata-parser-1.1.2-16.el6.x86_64.rpm
rpm -ivh python-urlgrabber-3.9.1-11.el6.noarch.rpm  
rpm -ivh yum-3.2.29-81.el6.centos.noarch.rpm yum-plugin-fastestmirror-1.1.30-40.el6.noarch.rpm

需要预先删除urlgrabber:

rpm -qa |grep urlgrabber
rpm -e python-urlgrabber-3.9.1-8.el6.noarch

到http://mirrors.163.com的 centos帮助文档 中下载CentOS6-Base-163.repo文件，存放到/etc/yum.repos.d中

#wget http://mirrors.163.com/.help/CentOS6-Base-163.repo

改名为：CentOS6-Base.repo

然后把文件里的$releasever都改为你的Linux版本（6或者5），也就是文件修改成如下即可：

: ？/$releasever/6/g 

yum clean all 清除原有缓存

yum makecache  获取yum列表

配置完成后最好升级下所有的包，避免安装R的时候报错：yum -y upgrade

2，安装R

In order to get R running on RHEL 6, we’ll need to add an additional repository that allows us to install the new packages, EPEL. Extra Packages for Enterprise Linux (or EPEL) is a Fedora Special Interest Group that creates, maintains, and manages a high quality set of additional packages for Enterprise Linux, including, but not limited to, Red Hat Enterprise Linux (RHEL), CentOS and Scientific Linux (SL).

su -c 'rpm -Uvh http://download.fedoraproject.org/pub/epel/6/i386/epel-release-6-8.noarch.rpm'

如果上一步怕麻烦没有升级所有包，只升级 curl和 nss即可，至少在我的虚拟机里面可以：

sudo yum update

sudo yum install R

查看R包：

yum list R-\*
