你好在世界的mod_wsgi [英] Hello World in mod_wsgi

问题描述

在我的追求一再未能得到我的烧瓶应用程序中使用Apache的运行的mod_wsgi 我决定尝试运行的 Hello World示例。下面是我 -

After failing repeatedly in my quest to get my flask application to run on Apache using mod_wsgi I decided to try running the hello world example. Here is what I have -

目录结构（我改变了Apache默认的 /无功/网络到〜/的public_html ）

Directory Structure (I changed the apache default /var/www to ~/public_html)

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

test_wsgi.wsgi文件

test_wsgi.wsgi file

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]

虚拟主机配置文件（称为testwsgi） - 这个位于的/ etc /启用站点-的Apache2 / /

<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>

当我尝试将本地主机/ WSGI 在浏览器上，我得到一个404 Not Found错误。我究竟做错了什么？这是我第一次尝试部署在生产服务器上的应用程序。到现在为止我花了使用谷歌应用程序引擎的简单方法。我不能继续我的部署应用程序烧瓶直到启动并运行。非常感谢！

When I try going to localhost/wsgi on the browser I get a 404 Not Found error. What am I doing wrong? This is the first time I'm trying to deploy an app on a production server. Until now I took the easy way of using Google App Engine. I cant proceed to deploy my flask app until this is up and running. Thanks a lot!

推荐答案

您需要使用绝对路径，即不使用〜。这工作得很好，我...

You need to use an absolute path, i.e. don't use ~. This works fine for me...

[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，我成立了 / etc / hosts中，所以我可以保证我可以在查询的主机名混流...

First I set up a hostname in /etc/hosts, so I could ensure that I can mux on the hostname in the query...

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

重新启动Apache，并出具wget的......

Restart apache, and issue a wget...

[mpenning@tsunami public_html]$ wget http://wsgihost/
