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 yum install epel-release
[root@iZ289zd8c52Z ~]#yum install epel-release Loaded plugins: langpacks base | 3.6 kB 00:00:00 epel | 4.3 kB 00:00:00 extras | 3.4 kB 00:00:00 updates | 3.4 kB 00:00:00 (1/7): base/7/x86_64/group_gz | 155 kB 00:00:00 (2/7): epel/x86_64/group_gz | 170 kB 00:00:00 (3/7): extras/7/x86_64/primary_db | 132 kB 00:00:00 (4/7): epel/x86_64/updateinfo | 567 kB 00:00:00 (5/7): epel/x86_64/primary_db | 4.1 MB 00:00:04 (6/7): updates/7/x86_64/primary_db | 4.9 MB 00:00:04 (7/7): base/7/x86_64/primary_db | 5.3 MB 00:00:05 Resolving Dependencies --> Running transaction check ---> Package epel-release.noarch 0:7-6 will be installed --> Finished Dependency Resolution Dependencies Resolved =============================================================================================================================================================================================== Package Arch Version Repository Size =============================================================================================================================================================================================== Installing: epel-release noarch 7-6 epel 14 k Transaction Summary =============================================================================================================================================================================================== Install 1 Package Total download size: 14 k Installed size: 24 k Is this ok [y/d/N]: y Downloading packages: epel-release-7-6.noarch.rpm | 14 kB 00:00:00 Running transaction check Running transaction test Transaction test succeeded Running transaction Installing : epel-release-7-6.noarch 1/1 warning: /etc/yum.repos.d/epel.repo created as /etc/yum.repos.d/epel.repo.rpmnew Verifying : epel-release-7-6.noarch 1/1 Installed: epel-release.noarch 0:7-6 Complete!
2、安装 yum install nodejs

3、yum install npm (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）
