Node让你可以用javascript编写服务器端程序，让javascript脱离web浏览器的限制，像C#、JAVA、Python等语言一样在服务器端运行，这也让一些熟悉Javascript的前端开发人员进军到服务器端开发提供了一个便利的途径。 Node是基于Google的V8引擎封装的，并提供了一些编写服务器程序的常用接口，例如文件流的处理。Node的目的是提供一种简单的途径来编写高性能的网络程序。

1，下载源码

在node.js的官方网站下载最新的源代码，node.js官方的升级比较快，如果没有特殊需求，还是下载最新的源码吧

地址：http://nodejs.org/download/

32bit 和 64bit根据自己需求爱好选择

我下载的是 node-v0.8.7.tar.gz，下载完解压

tar –zxvf node-v0.8.7.tar.gz

2，安装

先保证gcc之类的都已经安装好

yum install gcc gcc-c++

还需要python 一般的linux都有，版本需要2.6+ 但是好像不支持python3.×。

./configure –help

[root@local node-v0.8.7]# ./configure -help

  --without-npm         Don't install the bundled npm package manager
  --without-waf         Don't install node-waf
  --without-ssl         Build without SSL
  --without-snapshot    Build without snapshotting V8 libraries. You might
                        want to set this for cross-compiling. [Default: False]
  --shared-v8           Link to a shared V8 DLL instead of static linking
  --shared-v8-includes=SHARED_V8_INCLUDES
                        Directory containing V8 header files
  --shared-v8-libpath=SHARED_V8_LIBPATH
                        A directory to search for the shared V8 DLL
  --shared-v8-libname=SHARED_V8_LIBNAME
                        Alternative lib name to link to (default: 'v8')
  --shared-openssl      Link to a shared OpenSSl DLL instead of static linking
  --shared-openssl-includes=SHARED_OPENSSL_INCLUDES
                        Directory containing OpenSSL header files
  --shared-openssl-libpath=SHARED_OPENSSL_LIBPATH
                        A directory to search for the shared OpenSSL DLLs
  --shared-openssl-libname=SHARED_OPENSSL_LIBNAME
                        Alternative lib name to link to (default:
                        'crypto,ssl')
  --no-ssl2             Disable OpenSSL v2
  --shared-zlib         Link to a shared zlib DLL instead of static linking

                        Directory containing zlib header files
  --shared-zlib-libpath=SHARED_ZLIB_LIBPATH
                        A directory to search for the shared zlib DLL
  --shared-zlib-libname=SHARED_ZLIB_LIBNAME
                        Alternative lib name to link to (default: 'z')
  --with-dtrace         Build with DTrace (default is true on supported
                        systems)
  --without-dtrace      Build without DTrace
  --with-etw            Build with ETW (default is true on Windows)
  --without-etw         Build without ETW
  --gdb                 add gdb support
  --dest-cpu=DEST_CPU   CPU architecture to build for. Valid values are: arm,
                        ia32, x64
  --no-ifaddrs          Use on deprecated SunOS systems that do not support
                        ifaddrs.h
  --with-arm-float-abi=ARM_FLOAT_ABI
                        Specifies which floating-point ABI to use. Valid
                        values are: soft, softfp, hard

默认安装在/usr/local下

没有什么特殊需求的，就直接

[root@local node-v0.8.7]# ./configure
{ 'target_defaults': { 'cflags': [],
                       'default_configuration': 'Release',
                       'defines': [],
                       'include_dirs': [],
                       'libraries': []},
  'variables': { 'clang': 0,
                 'gcc_version': 44,
                 'host_arch': 'x64',
                 'node_install_npm': 'true',
                 'node_install_waf': 'true',
                 'node_prefix': '',
                 'node_shared_openssl': 'false',
                 'node_shared_v8': 'false',
                 'node_shared_zlib': 'false',
                 'node_use_dtrace': 'false',
                 'node_use_etw': 'false',
                 'node_use_openssl': 'true',
                 'target_arch': 'x64',
                 'v8_no_strict_aliasing': 1,
                 'v8_use_snapshot': 'true'}}
creating  ./config.gypi
creating  ./config.mk

[root@local node-v0.8.7]# make

[root@local node-v0.8.7]# make install

如果不报错就安装ok了

测试一下 建一个server.js，代码如下：

var http = require('http');
http.createServer(function (req, res) {res.writeHead(200, {'Content-Type': 'text/plain'});res.end('Hello World\n');
}).listen(80, '127.0.0.1');
console.log('Server running at http://127.0.0.1:/');

[root@local ~]# node server.js

浏览器打开http://127.0.0.1

如果没有图形界面，127.0.0.1地址修改为对应服务器ip，然后访问http://×××/
