【安装Nodejs】CentOS7 下安装NodeJs+Express+MongoDB+Redis
最近想拿NodeJS做个文档管理系统玩玩，看看mongdb的gridfs效率咋样，谁晓得因为一个Yeoman的脚手架，整来整去的把文件权限全部搞乱，一想算了，还是重来搞一套吧！
1、安装 yuminstallepel-release

3、yuminstallnpm (安装npm管理)
4、npm install -g n （安装 n 用来管理nodejs）
5、n stable （将nodejs升级到最新的稳定版本）
6、node -v （查看当前nodejs的版本，若还是之气的版本，那就请重启服务器，shutdown -r now）
