I don’t understand the reason for the error: Tue Jan 11 15:27:45 2022 – failed to open python file /root/eva/lawyer/lawyer/wsgi.py I can’t understand why uwsgi can’t open this python file. The path to it is right
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
Tell me, please, what could be the cause of the error and how to solve it? This seems like an easy problem to solve. But I couldn’t find information about it on the Internet

Answer
Check your file permissions for the Django project.You have your WSGI worker configured to use the account ‘www-data’. Either change this to an account that has access to the directories and file, or change the files permissions.
You can validate the file permissions by running ls -la in the directory. The third column shows the owner and the fourth column shows the group.
-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
You can change file and folder permissions by running chown www-data:www-data ./* in the project directory.
I do not recommend keeping the files in your root directory, that should be protected. Instead consider moving them to /var/www or /var/app.
To validate if its a permissions issue, you could change your uWSGI configuration to make the uid and gid root, but do not use this in a production setting.
