Hello everyone. A few days ago, I am trying to install and configure mailman 3, in a Centos7. and the truth has not been achieved. I am already a little desperate.

I'll tell you First I install the hyperkitty-el.repo repository and install mailman 3, hyperkitty and postorius. Initially when reviewing and making some minor modifications to the mailman configuration file, the service apparently rises without major problems.

The problem occurs when I try to configure the web interfaces. Initially the apache server did not start, with a series of errors. Following the instructions of the document published here: http://www.admin-magazine.com/Archive/2015/29/Mailman-3.0-a-long-time-coming... I managed to eliminate the initial errors, which prevented to raise the Apache server. However, when trying to access the web pages, in the case of hyperkitty, I get an error 500 with an "internal server error". In the case of postorius, I get an error 403 forbidden.

In the mail, I receive a log, with the following content:

Traceback (most recent call last): File "/ usr / bin / django-admin", line 5, in <module> management.execute_from_command_line () File "/usr/lib/python2.7/site-packages/django/core/management/__init__.py", line 354, in execute_from_command_line utility.execute () File "/usr/lib/python2.7/site-packages/django/core/management/__init__.py", line 303, in execute settings.INSTALLED_APPS File "/usr/lib/python2.7/site-packages/django/conf/__init__.py", line 48, in __getattr__ self._setup (name) File "/usr/lib/python2.7/site-packages/django/conf/__init__.py", line 44, in _setup self._wrapped = Settings (settings_module) File "/usr/lib/python2.7/site-packages/django/conf/__init__.py", line 92, in __init__ mod = importlib.import_module (self.SETTINGS_MODULE) File "/usr/lib64/python2.7/importlib/__init__.py", line 37, in import_module __import __ (name) ImportError: No module named settings

In the Apache logs, it also shows the following: [Mon Dec 11 21: 48: 41.875069 2017] [authz_core: error] [pid 15333] [client my-client-ip: 33584] AH01630: client denied by server configuration: / etc / postorius / sites / default / srv

when I execute the command: django-admin check

throws me the following:

django.core.exceptions.ImproperlyConfigured: Requested setting DATABASES, but settings are not configured. You must either define the environment variable DJANGO_SETTINGS_MODULE or call settings.configure() before accessing settings.

checking the ports, I can see that python has open ports 8000 in 127.0.0.1, and 8001 in external ip,

for more than I have looked for information, documentation, etc, about the procedure of the installation. all the documentation I found, part of the premise of an installation, clean from git, by pip, but none from the yum and rpm. So it is difficult for me to determine what to apply, and what not. apparently no one has installed, or has had problems in the installation from repositories, or I am omitting some step (most likely) that I could not determine.

the bad thing, is that in postfix, I have everything configured, with digital signatures, so I would not like to lose all that work, as to start with an installation from 0.

If you can help me, it would be very helpful. since I made the request of help in another list, of dev, to which it is supposed that the consultations should be made, according to the historical mails, but I never received answer.

Of course, thank you very much for any help and guidance they can give me.
