首先，本地虚拟机装centOs是很好的选择，但是需要在家里和公司同时搭好相同的环境比较麻烦，而且也不方便小团队一起折腾。

\r\n

亚马逊的免费虚拟机只要不跑太复杂的运算大概不会有额外的费用，而且亚马逊么有被墙，国内的托管目前cnode的邀请号求不到啊，还是自己动手丰衣足食吧。

\r\n
2，如何申请免费一年的EC2\r\n

在http://aws.amazon.com/上注册。

\r\n

网上有很多教程，请自行GOOGLE。

\r\n

3，EC2虚拟机简单的管理和设置

\r\n

新建KEY，保存。

\r\n

For MAC & Linux

\r\n

很简单，只要一句话

\r\n

ssh -i user.pem ec2-user[@ec2-XXX-XXX-XXX-XXX](/user/ec2-XXX-XXX-XXX-XXX).compute-1.amazonaws.com

\r\n

以上user.pem可以是你的KEY的路径。

\r\n

For PC

\r\n

putty 链接ec2-XXX-XXX-XXX-XXX.compute-1.amazonaws.com

\r\n

注意需要在connection->SSH->Auth里选上你的KEY，之前需要转pem到ppk。

\r\n

怎么看DNS名：在管理界面里，先点击你要查看的虚拟机，点右键，再弹出的菜单上点“connect”就可以看到如下图：

\r\n

其中ec2-XXX-XXX-XXX-XXX.compute-1.amazonaws.com是你的DNS名

\r\n

一般不太需要调整什么，可能要改的就是端口8080要开启。

\r\n

4，搭建node前的准备

\r\n

默认的liunx中不会吧所有工具都装好，一些基本的工具，需要我们自己装。

\r\n

以下：

\r\n

a. make

\r\n

b.gcc++

\r\n

c.curl

\r\n

d.git

\r\n

一句话安装：

\r\n

sudo yum install gcc-c++ openssl-devel make curl git

\r\n

\r\n
5，安装node\r\n

\r\n

wget http://nodejs.org/dist/node-v0.4.12.tar.gz\r\n
tar -xvf node-v0.4.12.tar.gz\r\n
cd node-v0.4.12\r\n
./configure\r\n
make

\r\n

由于是在云里跑的，所以make可能会花上30多分钟，我出去吃了个中饭，回办公室发现好了的。所以，不用在屏幕前傻等，出去走走，预防一下颈椎病。

\r\n

make install

\r\n

其他调整，由于EC2中path的问题，node装完了不一定能直接跑。所以有时候需要做些映射。

\r\n

sudo ln -s /usr/local/bin/node /usr/bin/node\r\n
sudo ln -s /usr/local/lib/node /usr/lib/node\r\n
sudo ln -s /usr/local/bin/npm /usr/bin/npm\r\n
sudo ln -s /usr/local/bin/node-waf /usr/bin/node-waf

\r\n

6，测试第一个静态文件服务

\r\n

先在/home/ec2-user/上建个nodeweb目录，里面放静态页面，然后可以测试了～～

\r\n

var libpath = require('path'),\r\n
    http = require(\"http\"),\r\n
    fs = require('fs'),\r\n
    url = require(\"url\"),\r\n
    mime = require('mime');\r\n
var path = \"/home/ec2-user/nodeweb\";\r\n
var port = 8080;\r\n
http.createServer(function (request, response) {\r\n
    var uri = url.parse(request.url).pathname;\r\n
    var filename = libpath.join(path, uri);\r\n
    libpath.exists(filename, function (exists) {\r\n
        if (!exists) {\r\n
            response.writeHead(404, {\r\n
                \"Content-Type\": \"text/plain\"\r\n
            });\r\n
            response.write(\"404 Not Found\\n\");\r\n
            response.end();\r\n
            return;\r\n
        }\r\n
        if (fs.statSync(filename).isDirectory()) {\r\n
            filename += '/index.html';\r\n
        }\r\n
        fs.readFile(filename, \"binary\", function (err, file) {\r\n
            if (err) {\r\n
                response.writeHead(500, {\r\n
                    \"Content-Type\": \"text/plain\"\r\n
                });\r\n
                response.write(err + \"\\n\");\r\n
                response.end();\r\n
                return;\r\n
            }\r\n
            var type = mime.lookup(filename);\r\n
            response.writeHead(200, {\r\n
                \"Content-Type\": type\r\n
            });\r\n
            response.write(file, \"binary\");\r\n
            response.end();\r\n
        });\r\n
    });\r\n
}).listen(port);
