I have been deploying django websites on a shared hosting platform (YouStable). With my latest attempt I get a 500 server error page, because it can’t find the settings file.
Background
I did previously manage to deploy a site that worked. I deleted that when I had problems because I had chosen app names that conflict with reserved words and I also discovered I could pip install the Bootstrap web framework (although I need to sort this issue first). I have since had problems creating a new site. I reported a problem when the hosting server was trying to run code from a virtual environment connected to a previous site ( the site and venv have been deleted). The hosting support techies have fixed that.
What I did.
The procedure for deployment involves creating a Python ‘app’ in CPanel's ‘Setup Python app’ by; selecting a Python version (I chose 3.11), choosing a name (‘myapp’), selecting the domain name and saving the app. This creates a virtual environment (or venv) using my username (‘username’), the app name and the Python version. For me:
/home/username/virtualenv/appname/3.11/
CPanel then displays the code to select and activate this venv for use in the terminal section of CPanel. I switched to the terminal, activated the venv, pip installed Django and used django-admin startproject … to create the site (‘mysite’). I then found the wsgi.py file in the project and saved that location in the CPanel Setup Python app
(/mysite/site/wsgi.py)
The CPanel confirms that it CAN find the settings file. Without any further changes this should produce the debug home page (with the rocket on). However I get a 500 server error page and an error log.
The stderr.log error log shows the server going through the same cycle twice, one of which is setout below. For most of a cycle it is using code from the correct venv, but with a couple of exceptions; once where it tries to use imp.py to load a passenger_wsgi.py (which it shouldn't because I've told it where the wsgi.py file is) and once to use importlib.py where it fails to find the settings file. Both times it uses
/opt/alt/python311/lib64/python3.11
instead of my venv and fails.
When I raised a support ticket I was advised to consult my developer (er, that's me). My questions are
Is the swap from my venv to /opt/alt… the cause of the error?
Is there anything more I can do to fix this?
Or do I need to go back to support because it is their problem?
Thanks in advance for any help with this.
The contents of the stderr.log are as follows:
