Centos 6.3Yum安装NodeJS

1. 添加epel源：

　　（1）查看机器位数 file /sbin/init 或者 file /bin/ls

　　（2）X64:

rpm -ivh http://download.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm

X32:

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

2. 导入key：

rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-

3. 添加remi源：

 rpm -ivh http://rpms.famillecollet.com/enterprise/remi-release-6.rpm
 rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY-remi 

4. 升级源：

sudo yum upgrade ca-certificates --disablerepo=epel

5. 安装nodeJS

 yum install gcc-c++
 yum -y install nodejs

问题破冰：

1. Cannot retrieve metalink for repository: epel.

 vi /etc/yum.repos.d/epel.repo

 #baseurl
 mirrorlist
 改成
 baseurl
 #mirrorlist

2. Cannot retrieve repository metadata (repomd.xml) for repository: epel.

 vi /etc/yum.repos.d/epel.repo
 #baseurl全部改为baseurl=http://centos.ustc.edu.cn/centos/5/os/i386/
 (执行替换命令):%s#baseurl=(原来的url)#baseurl=http://centos.ustc.edu.cn/centos/5/os/i386/#g
 yum clean all

3. 一定要注意，gcc-c++一定要被安装

yum install gcc-c++

另外附带编译安装：

 yum install gcc-c++ openssl-devel
 cd /usr/local/src  
 wget http://nodejs.org/dist/node-latest.tar.gz  
 tar zxvf node-latest.tar.gz
 ./configure  
 Make
 Make install
 npm install restify
