Question

在我使用mod_wsgi让我的烧瓶应用程序在Apache上运行的过程中反复失败后，我决定尝试运行hello world example。这就是我所拥有的 -

目录结构（我将apache默认/var/www更改为~/public_html）

- public_html    
   - wsgi-scripts
      - test_wsgi.wsgi
   - test_wsgi
      - test_wsgi.wsgi

test_wsgi.wsgi文件

def application(environ, start_response):
    status = '200 OK'
    output = 'Hello World!'

    response_headers = [('Content-type', 'text/plain'),
                        ('Content-Length', str(len(output)))]

    start_response(status, response_headers)

    return [output]

VirtualHost配置文件（称为testwsgi） - 位于/etc/apache2/sites-enabled/

<VirtualHost *:80>
    DocumentRoot ~/public_html/test_wsgi

    <Directory ~/public_html/test_wsgi>
        Order allow,deny
        Allow from all
    </Directory>

    WSGIScriptAlias /wsgi ~/public_html/wsgi-scripts/test_wsgi.wsgi

    <Directory ~/public_html/wsgi-scripts>
        Order allow,deny
        Allow from all
    </Directory>
</VirtualHost>

当我尝试在浏览器上转到localhost/wsgi时，我收到404 Not Found错误。我究竟做错了什么？这是我第一次尝试在生产服务器上部署应用程序。到目前为止，我采用了简单的方法来使用Google App Engine。我无法继续部署我的烧瓶应用程序，直到它启动并运行。非常感谢！

您需要使用绝对路径，即不要使用~。这对我来说很好......

[mpenning@tsunami public_html]$ sudo cat /etc/apache2/sites-available/wsgi_test
<VirtualHost *:80>
    ServerName wsgihost
    DocumentRoot /home/mpenning/public_html
    WSGIScriptAlias / /home/mpenning/public_html/test.wsgi
</VirtualHost>
[mpenning@tsunami public_html]$

首先我在/etc/hosts中设置了一个主机名，所以我可以确保我可以在查询中复用主机名...

[mpenning@tsunami public_html]$ grep wsgihost /etc/hosts
127.0.1.1       tsunami.foo.net  tsunami wsgihost
[mpenning@tsunami public_html]$

重启apache，并发出一个wget ...

[mpenning@tsunami public_html]$ wget http://wsgihost/
--2012-08-29 05:50:26--  http://wsgihost/
Resolving wsgihost... 127.0.1.1

[mpenning@tsunami public_html]$ cat index.html
Hello World![mpenning@tsunami public_html]$ #  <------

mod_wsgi中的Hello World
