Hi all, I'm trying to learn how to use web2py, it's my first time using a
framework to develop web apps,
I have to say it's being very hard to learn because all the documentation
is very outdated. Now I'm trying to set up web2py to work with postrgerSQL
and nginx on a fresh Debian 10 install.
Not sure how to do it properly since all the examples are for old linux
distros that don't use systemd, I tried using the script that I found here:
https://github.com/motasmarcelo/setup-web2py-nginx-uwsgi-debian8
because it's the most recent I could find
But I modified it to use Python3 as follows:
#!/bin/bashLOG_FILE=/tmp/setup-web2py.loglogged () { echo $(date +"%F_%T")
$* | tee -a $LOG_FILE}echo 'Setup-web2py-nginx-uwsgi-debian8.sh'echo 'Requires

I'm just testing locally so I don't have a public IP address or a domain
name so I just enter random names for domain name and app name.
I get a 502 bad gateway error when I try to browse the website.
In my /var/log/uwsgi/app/appname.log I get this errors:
Mon Jul 6 04:15:02 2020 - mapped 364600 bytes (356 KB) for 4 cores
Mon Jul 6 04:15:02 2020 - *** Operational MODE: preforking ***
Mon Jul 6 04:15:02 2020 - *** no app loaded. going in full dynamic mode ***
Mon Jul 6 04:15:02 2020 - *** uWSGI is running in multiple interpreter

Mon Jul 6 04:15:02 2020 - !!!!!!!!!!!!!! WARNING !!!!!!!!!!!!!!
Mon Jul 6 04:15:02 2020 - no request plugin is loaded, you will not be
able to manage requests.
Mon Jul 6 04:15:02 2020 - you may need to install the package for your
language of choice, or simply load it with --plugin.
Mon Jul 6 04:15:02 2020 - !!!!!!!!!!! END OF WARNING !!!!!!!!!!
I need help to make this work since I really don't know how to fix this
because I basically don't know what I'm doing and I would also like to run
uwsgi in emperor mode but I don;t really know how to achieve that, any help
would be highly appreciated.
