如何在 Ubuntu 上为 Python 设置 Mod_WSGI

Question

我正在尝试在我的 Ubuntu 机器上设置 MOD_WSGI。我找到了说我需要执行以下步骤的步骤，我在http://ubuntuforums.org/showthread.php?t=833766

1. 须藤 apt-get 安装 libapache2-mod-wsgi
2. 须藤 a2enmod mod-wsgi
3. 须藤 /etc/init.d/apache2 重启
4. sudo gedit /etc/apache2/sites-available/default 并更新目录

<Directory /var/www/>
  Options Indexes FollowSymLinks MultiViews ExecCGI

  AddHandler cgi-script .cgi
  AddHandler wsgi-script .wsgi

  AllowOverride None
  Order allow,deny
  allow from all
</Directory>

5. 须藤 /etc/init.d/apache2 重启

6. 创建了 test.wsgi

   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]
   

第 2 步失败，因为它说即使 apt-get 找到它也找不到 mod-wsgi。如果我继续执行这些步骤，python 应用程序只会在浏览器中显示为纯文本。

任何想法我做错了什么？

Description: Python WSGI adapter module for Apache
 The mod_wsgi adapter is an Apache module that provides a WSGI (Web Server
 Gateway Interface, a standard interface between web server software and
 web applications written in Python) compliant interface for hosting Python
 based web applications within Apache. The adapter provides significantly
 better performance than using existing WSGI adapters for mod_python or CGI.

Answer 1

我发现这是一个存在超过一年的 mod_wsgi apt-get 软件包的已知错误！详情见http://www.mail-archive.com/ubuntu-bugs@lists.ubuntu.com/msg1147225.html。apt-get 包没有 wsgi.load 文件，因此需要通过执行上面链接中的步骤来创建。

感谢所有帮助过的人！

查看模块是否实际正确加载：

apache2ctl -t -D DUMP_MODULES
