Please help me through this.

请帮我度过这个难关。

In your Apache configuration, you need to change the Directory directive to: <Directory /var/www/cgi-bin> if this is where you intend to host your mod_python scripts.

在Apache配置中，需要将目录指令更改为: ，如果这是您打算托管mod_python脚本的地方。

UPDATE:

更新:

You're placing your python script in /var/www/cgi-bin but /cgi-bin/ is defined to point to /usr/lib/cgi-bin. You need to standardize on one location for /cgi-bin/.

您将python脚本放置在/var/www/cgi-bin中，但是/cgi-bin/被定义为指向/ usr/lib/cgi-bin。您需要在一个位置上标准化/cgi-bin/。

Here's what I would propose as your corrected Apache configuration. Note that I didn't remove any lines, I only commented out the lines that are not needed or have been replaced.

以下是我建议的修改后的Apache配置。注意，我没有删除任何行，我只注释掉不需要的行或者已经被替换的行。

<VirtualHost *:80>
    ServerAdmin webmaster@localhost

    DocumentRoot /var/www
    <Directory />
        Options FollowSymLinks
        AllowOverride None
    </Directory>

    #<Directory /var/www>
    <Directory /var/www/cgi-bin>
        Options Indexes FollowSymLinks MultiViews
                AllowOverride None
                Order allow,deny
                allow from all
                AddHandler mod_python .py
                PythonHandler mod_python.publisher
                PythonDebug On
    </Directory>

    #ScriptAlias /cgi-bin/ /usr/lib/cgi-bin/
    #<Directory "/usr/lib/cgi-bin">
    #    AllowOverride None
    #    Options +ExecCGI -MultiViews +SymLinksIfOwnerMatch
    #    Order allow,deny
    #    Allow from all
    #</Directory>

    ErrorLog /var/log/apache2/error.log

    # Possible values include: debug, info, notice, warn, error, crit,
    # alert, emerg.
    LogLevel warn

    CustomLog /var/log/apache2/access.log combined

    Alias /doc/ "/usr/share/doc/"
    <Directory "/usr/share/doc/">
        Options Indexes MultiViews FollowSymLinks
        AllowOverride None
        Order deny,allow
        Deny from all
        Allow from 127.0.0.0/255.0.0.0 ::1/128
    </Directory>

</VirtualHost>

UPDATE 2:

更新2:

Now that your Apache configuration is correct, and we've verified that your module is importing correctly, you're still getting a 404. This is because you are using the mod_python publisher handler, which expects a different usage than what you have implemented. Basically, you have implemented a simple CGI script that just prints output. mod_python has a specific API for executing your module. You should try this example to get an understanding of how it works.

既然您的Apache配置是正确的，并且我们已经验证了您的模块是正确导入的，那么您仍然可以得到404。这是因为您使用的是mod_python发布者处理程序，它期望的使用与您所实现的不同。基本上，您已经实现了一个简单的CGI脚本，它只打印输出。mod_python有一个用于执行模块的特定API。您应该尝试这个示例来了解它是如何工作的。

To implement your test module as a valid mod_python publisher, you could change hello.py to this:

要实现您的测试模块作为一个有效的mod_python发布者，您可以更改hello。py:

def index(req):
    return """<html>
<head>
<title>Hello Word - First CGI Program</title>
</head>
<body>
<h2>Hello Word! This is my first CGI program</h2>
</body>
</html>"""

Note that the reason you were getting a 404 error (even though the module was imported) is explained on this page:

请注意，您获得404错误的原因(尽管模块是导入的)在此页面上有说明:

The traversal will stop and HTTP_NOT_FOUND will be returned to the client if:

遍历将停止，HTTP_NOT_FOUND将返回给客户端:

Any of the traversed object's names begin with an underscore ("_"). Use underscores to protect objects that should not be accessible from the web.

任何遍历对象的名称都以下划线(“_”)开头。使用下划线来保护不应该从web访问的对象。

A module is encountered. Published objects cannot be modules for security reasons.

遇到一个模块。出于安全原因，发布的对象不能是模块。

If an object in the path could not be found, HTTP_NOT_FOUND is returned to the client.

如果无法找到路径中的对象，则将HTTP_NOT_FOUND返回给客户端。
