dotcloud 托管 python web应用 第一章 helloworld

dotcloud主页地址：www.dotcloud.com ，算是一个不错的python空间。这两天，我试过了GAE，去SAE排了个队，无奈本人菜鸟一只，玩儿不转GAE，而且最近人品欠佳，SAE前面还有43人排队，所以只能另寻良枝了。值得欣喜的是，我找到了dotcloud,它支持几乎所有的python框架，当然有我正在学的webpy。废话说多了，开始记录下。（ubuntu 12.04）

参照http://docs.dotcloud.com/firststeps/install/

第一步：安装Command-Line Interface client (CLI)

ctrl+alt+t 呼出终端，输入一下代码

$ sudo easy_install pip && sudo pip install dotcloud

安装完成后，会提示输入api key，可以在setting面板中找到，粘贴到终端里，回车ok

$ dotcloud
Enter your api key (You can find it at http://www.dotcloud.com/account/settings):

第二步：在本机编写helloworld

新建一个文件夹作为项目文件夹，完成后进入文件夹

$ mkdir helloworldapp
$ cd helloworldapp

为了方便，可以把测试程序中的文件都复制到helloworldapp文件夹下。（测试文件 http://download.youkuaiyun.com/detail/mchange/4432926）

第三步：在dotcloud创建应用

$ dotcloud create helloworldapp
Created application "helloworldapp" using the flavor "sandbox" (Use for development, free and unlimited apps. DO NOT use for production.)

将本地应用上传到dotcloud

$ dotcloud push helloworldapp
...

到此为止，示例结束。记录几个小技巧：

1。dotcloud命令帮助

在终端输入dotcloud -h 命令，查看帮助命令

例如，要删除一个上传到dotcloud的文件， 可以输入：dotcloud destroy appname
