我不明白错误的原因：Tue Jan 11 15:27:45 2022 - failed to open python file /root/eva/lawyer/lawyer/wsgi.py 我不明白为什么 uwsgi 不能t 打开这个 python 文件。通往它的道路是正确的

myapp.ini：

[uwsgi]
chdir = /root/eva/lawyer
env = DJANGO_SETTINGS_MODULE= lawyer.settings
wsgi-file = /root/eva/lawyer/lawyer/wsgi.py
#module = lawyer.uwsgi:application
workers = 1
max-requests = 5000
#plugins-dir=/usr/lib/uwsgi/plugins/
plugins = python3
#virtualenv = /root/eva/venv
pythonpath = /root/eva/venv/lib/python3.8/site-packages
processes = 5
threads = 2
master = true
die-on-term = true
socket = /run/uwsgi/app/myapp/socket
chmod-socket = 666
vacuum = true
uid = www-data
gui = www-data

请告诉我，错误的原因可能是什么以及如何解决？这似乎是一个很容易解决的问题。但是我在互联网上找不到有关它的信息

【问题讨论】：

uwsgi 以用户 'www-data' 的身份运行是 wsgi 文件和父目录设置是否具有正确的权限，以便用户可以读取它？
我不确定。告诉我，我该如何检查这个？如何授予访问权限？
您可以在您的目录中运行ls -la 以确认文件所有者和组权限。出于测试的目的，我会将您的 Django 目录中的所有内容设置为可通过运行 www-data 访问 chown -R www-data:www-data ./* 可能更好的文件位置将在 /var/www

标签： python django ubuntu uwsgi wsgi

【解决方案1】：

检查您对 Django 项目的文件权限。您已将 WSGI 工作人员配置为使用帐户“www-data”。将其更改为有权访问目录和文件的帐户，或更改文件权限。

您可以通过在目录中运行ls -la 来验证文件权限。第三列显示所有者，第四列显示组。

-rwxrwxrwx 1 lbird lbird      548 Nov  3 11:52  default-soapui-workspace.xml
-rwxrwxrwx 1 lbird lbird  2785280 Jun  5  2021  ntuser.dat.LOG1
-rwxrwxrwx 1 lbird lbird  3256320 Jun  5  2021  ntuser.dat.LOG2
-rwxrwxrwx 1 lbird lbird       20 Jun  5  2021  ntuser.ini
-rwxrwxrwx 1 lbird lbird     8677 Nov  3 11:52  soapui-settings.xml

您可以通过在项目目录中运行chown www-data:www-data ./* 来更改文件和文件夹权限。

我不建议将文件保存在您的根目录中，因为它应该受到保护。而是考虑将它们移至/var/www 或/var/app。

要验证是否是权限问题，您可以更改 uWSGI 配置以使 uid 和 gid 成为 root，但不要在生产设置中使用它。
