“ Errno 13 权限被拒绝 'bnr_code.csv'”？

Question

我已经使用 apache2 和 wsgi 在服务器上部署了一个 Django 项目，它显示了一个错误，我可能知道它为什么会出现。

错误：

IOError at /
[Errno 13] Permission denied: 'bnr_code.csv'
Request Method: GET
Request URL:    http://93.188.167.63:8080/pep_learn/
Django Version: 1.10.8
Exception Type: IOError
Exception Value:    
[Errno 13] Permission denied: 'bnr_code.csv'
Exception Location: /home/pep_web/binaryDs/views.py in <module>, line 6
Python Executable:  /usr/bin/python
Python Version: 2.7.12

我试过一些中伤的解决方案，如下所示：

chmod 777 pep_web/

chmod 771 pep_web/

sudo chown :www-data pep_web/

但没有任何效果

这是使用 'bnr_code.csv'

的文件

AA = {"A":"1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0",

不要使用文件的相对路径，使用绝对路径。 mod_wsgi.

的文档中解释了此问题

http://modwsgi.readthedocs.io/en/develop/user-guides/application-issues.html#application-working-directory

通过执行以下操作计算文件的位置：

filename = os.path.join(os.path.dirname(__file__), 'bnr_code.csv')

“ Errno 13 权限被拒绝 'bnr_code.csv'”？

" Errno 13 Permission denied 'bnr_code.csv'"?

python

django

mod-wsgi

apache2
