CentOS 6.5安装Node.js, npm

CentOS上可以通过下载*.tar.gz安装包的方式自己解压缩、编译的方式安装，同时还可以采用EPEL的方式安装：

Node.js and npm are available from the Fedora Extra Packages for Enterprise Linux (EPEL) repository. If you haven't already done so, firstenable EPEL.

To check if you have EPEL, run

yum repolist

if you don't see epel, install it via RPM (At the time of this writing, the last version is 6.8.)

rpm -Uvh http://download-i2.fedoraproject.org/pub/epel/6/i386/epel-release-6-8.noarch.rpm

And then run the following command to install node and npm:

sudo yum install nodejs npm --enablerepo=epel

or if this doesn't work for you install node separately:

sudo yum install npm --enablerepo=epel
