Erlang-Web下载，编译以及创建Web应用并运行

转载：http://blog.csdn.net/minyskirt/article/details/5031221

ErlangWeb是一个开源的基于Http协议的应用框架，主要是利用Erlang语言来快速、简洁的建立Web应用程序，不过目前这个框架只支持基于Linux平台上。它的官方站点是http://erlang-web.org/.

以下将介绍从它的网站上下载源代码并且编译，然后利用框架来搭建一个Web应用程序：

一 、下载

从http://wiki.erlang-web.org/Downloading上下载最新版的框架。初次之外，还可以找到以前版本框架，下载到本地后文件是erlangweb-1.4.tar.gz。利用tar解压缩到/otp/路径下。

 

二 、编译

进入解压缩后的/opt/erlangweb-1.4目录中，在终端输入bin/compile.erl命令进行编译：

编译完成后，在lib目录下的ebin目录中将会看到编译后的文件。

 

三 、创建一个Web应用

现在ErlangWeb框架已经编译好了，然后可以利用bin/start这个命令来创建一个新的Web应用了。首先，在我们在需要创建Web应用的路径中新建一个Web应用文件夹，比如/root/www/new_project。然后利用下面的命令创建：

root@ubuntu:~/www/new_project# /otp/erlangweb-1.4/bin/start.erl yaws

Element created: config

Element created: docroot

Element created: log

Element created: pipes

Element created: templates

Element created: bin

Element created: lib

Element created: releases

Element created: releases/0.1

Element created: templates/cache

Element created: docroot/conf

Element created: bin/heart

Element created: bin/to_erl

Element created: bin/run_erl

Element created: bin/start

Element created: bin/stop

Element created: bin/connect

Element created: bin/start_interactive

Element created: bin/start_erl

Element created: releases/start_erl.data

Element created: config/dispatch.conf

Element created: config/errors.conf

Element created: templates/404.html

Element created: templates/501.html

Element created: config/project.conf

Element created: docroot/autocomplete.css

Element created: docroot/indicator.gif

Element created: docroot/jquery.autocomplete.js

Element created: docroot/jquery.js

Element created: templates/welcome.html

Element created: releases/0.1/start.rel

Element created: releases/0.1/start.script

Element created: releases/0.1/start.boot

Element created: config/yaws.conf

Element created: docroot/conf/mime.types

Element created: config/inets.conf

Element created: config/inets_https.conf

Element created: config/ewgi_inets.conf

Element created: config/ewgi_inets_https.conf

Element created: config/errors_description.conf

Element created: releases/0.1/sys.config

Element created: Emakefile

Element created: bin/compile.erl

Element created: bin/add.erl

Element created: bin/generate.erl

Element created: bin/test.erl

Element created: bin/e_component.erl

后面的yaws参数表示我们的这个应用运行在yaws容器中，创建成功后，它将在new_project目录中生成以下文件夹：



 

四 运行创建的web应用

利用start生成了Web应用之后，还需要编译新创建的Web应用，编译web应用是利用下面的命令行：

root@ubuntu:~/www/new_project# bin/compile.erl

Compilation completed!

编译成功，你我们就可以运行了，输入下面的命令

root@ubuntu:~/www/new_project# bin/start

Starting Erlang Web

 

Erlang Web已经运行起来了，我们可以在浏览器中输入http://localhost:8080/来检查是否运行成功。如果成功，将会在页面中显示：

Welcome to the Erlang Web!
