It looks like you are not able to access your Django project because the ALLOWE_HOSTS for the project is not properly set. It also look like your project is missing some pip dependencies. Were you able to follow our official guide I posted in a previous message?

Once you have Django project created using that guide, you can configure Apache follow the next one

https://docs.bitnami.com/aws/infrastructure/django/get-started/deploy-django-project/#production

Hi @gongomgra
Thank you for your help

I am not sure if this report is up to date as you see
[Mon Apr 13 16:58:19.616793 2020] Invalid HTTP_HOST header: '18.195.166.105'. You may need to add '18.195.166.105' to ALLOWED_HOSTS.

[Tue Apr 14 14:30:29.012378 2020] ModuleNotFoundError: No module named 'notifications'

These records are three and two days ago, before I create this post/ticket
This means no Apache server errors last two days, please, correct me if otherwise

The website runs on 8000 port without issues, I attach an image

Regrading the static files it happens when debug is false which is another problem I will try to solve it later on
but now my biggest problem is keeping the website running using apache

Do you want me to send/write the code of the files wsgi.py httpd-app.conf httpd-prefix.conf bitnami.conf ?

I have no experience working neither with apache nor with wsgi

Thank you

gongomgra 2020-04-17 08:44:00 UTC #9

Hi @Majali,

I posted the error messages I found in the bnsupport bundle you send us. Can you check the logs in case you find similar messages in more recent dates?

Apart from that, I think your Apache service (running under the user daemon) can't access them. Can you try running the command below? Replace YOUR_PROJECT with the correct name

sudo chown -R bitnami:daemon /opt/bitnami/apps/django/django_projects/YOUR_PROJECT

After that, restart all services and try again.

Majali 2020-04-17 14:13:27 UTC #10

Hi @gongomgra
Thank you for your help

I tried the code you wrote to me

sudo chown -R bitnami:daemon /opt/bitnami/apps/django/django_projects/lewhdk

sudo /opt/bitnami/ctlscript.sh restart apache

Rebooted the instance

/opt/bitnami/apache2/logs/error_log

I still get "Permission denied"

I could access the error_log file using Filezilla
Here is what I receive every time I try to access the website

gongomgra 2020-04-20 08:20:36 UTC #11

Hi @Majali,

Can you try running the command below to give execution permissions to the wsgi.py file?

sudo chmod +x /opt/bitnami/apps/django/django_projects/lewhdk/lewhdk/wsgi.py

Then, restart services and try to visit your website again

`
sudo /opt/bitnami/ctlscript.sh restart

Majali 2020-04-24 10:07:05 UTC #12

Hi @gongomgra

Thank you for your help,

I fixed the issue, my problem was some apps were not installed properly

Thank you again for your help

gongomgra 2020-04-27 08:52:52 UTC #13

Hi @Majali,

Thanks for the info. I'm glad you fixed your issue! Could you post here your solution so it can help other users in the future?

Majali 2020-04-30 18:03:59 UTC #14

Thank you again @gongomgra

The tutorial here https://aws.amazon.com/getting-started/hands-on/deploy-python-application/ is correct

I had three issues
1- My website was running when I serve it using the command python manage.py runserver 0.0.0.0:80 but was not running using apache, the problem was some components were not installed successfully

2- I was not able to access the apache error log file using /opt/bitnami/apache2/logs/error_log I receive Permission denied. I solved it by accessing the file using SSH Filezilla

3- When running on apache, the server did not serve the static files, collectstatic did not work, I had to copy the static files manuallay

Then all worked fine
