我坚持将我的 Django 项目迁移到生产服务器。这是情况。我的最终结果页面(HTML 源代码)如下所示:
Number of exponentials: 1 <br /><br />
Function: 98.919106*2.71828182845905**(-0.014026249*t) <br /><br />
Parameters of exponentials: {'a': [98.919105999999999], 'k': [0.014026248999999999], 'c': [0]} <br /><br />
Non physical solution: False <br /><br />
<img src="plots/data_2e_03.png" alt="some_text"/>
它是一个由我的 Django 应用程序中的数据填充的模板。模板如下所示:
Number of exponentials: {{rp.user_choice.number_of_exponentials}} <br /><br />
Function: {{rp.user_choice.function}} <br /><br />
Parameters of exponentials: {{rp.user_choice.parameters_of_exponentials}} <br /><br />
Non physical solution: {{rp.user_choice.non_physical_solution}} <br /><br />
<img src="plots/{{rp.input_file_name}}.png" alt="some_text"/>
问题是图像没有显示。只有 alt 被打印出来。当我检查 html 源代码(粘贴在上面)时,它显示 plots/data_2e_03.png 作为链接(是的,在 HTML 源代码中)。当我单击它时,它会将我带到另一个页面的来源。

<p>The server encountered an internal error or

<address>Apache/2.2.16 (Debian) Server at bioinformatika.djangoserver Port 80</address>
</body></html>
这是我的 apache 站点配置:
<VirtualHost *:80>
ServerName bioinformatika.djangoserver
DocumentRoot /home/user/bioinformatika/Server/bioinformatika/apache
Alias /plots/ /home/user/bioinformatika/Server/bioinformatika/bioinformatika/plots/
<Directory /home/user/bioinformatika/Server/bioinformatika/bioinformatika/plots>
Order deny,allow
Allow from all
</Directory>
<Directory /home/user/bioinformatika/Server/bioinformatika/apache>
Order allow,deny
Allow from all
</Directory>
WSGIDaemonProcess bioinformatika.djangoserver processes=2 threads=15 display-name=%{GROUP}
WSGIProcessGroup bioinformatika.djangoserver
WSGIScriptAlias / /home/user/bioinformatika/Server/bioinformatika/apache/django.wsgi
为了让 apache 处理我的媒体文件,我添加了:
Alias /plots/ /home/user/bioinformatika/Server/bioinformatika/bioinformatika/plots/
<Directory /home/user/bioinformatika/Server/bioinformatika/bioinformatika/plots>
Order deny,allow
Allow from all
</Directory>
其他部分是关于设置 apache、mod_wsgi 和 Django,并且正在工作。
一旦我删除了 Django settings.py 中的调试。显示源的页面(带有内部服务器错误)现在已呈现并显示在浏览器中。/etc/log/apache2/error.log 给出以下内容:

任何建议表示赞赏。我认为奇怪的行为可能与我的服务器设置有关,而我的结果不是默认的,容易解决的问题,如果是这种情况,如果有人可以请检查我的 apache 配置是否正确,我将不胜感激。
更新:
这是我想念配置路径的问题。我不清楚 STATIC_URL、STATIC_ROOT、MEDIA_URL 和 MEDIA_ROOT 的含义,这导致了我无法完全诊断的部署问题中的问题。
但是,避免这种情况的方法是对如何在开发和生产服务器上提供文件有一个有效的概念性知识。
