I followed the documentation about how to install, but the nginx only give me its default page.
The flaskbb never shows.
I tryed remove the nginx default config file and only include the flaskbb file, but than a got a 502 bad request.

All the installation are fine, but I cant run the flaskbb on the nginx. Any help?

Here is my configs files.

Looks like its an uwsgi issue. Could you post the log from uwsgi?

Hi, You are right, the problem is the uwsgi. But it is too hard to setup, I never use it before.
At firt the console dont shows nothing, I finally manage to run the uwsgi and the nginx to see an error, but I cant find where they are logging the errors.

The only think that works is running the uwsgi like this:
uwsgi --plugin python --socket 127.0.0.1:30002 --wsgi-file /home/andre/py/rv/flaskbb/wsgi.py --master --processes 4 --threads 2 --stats 127.0.0.1:9191

But they show me this in the browser: Internal Server Error
The uwsgi give-me this in the console: --- no python application found, check your startup logs for errors ---
But as I say, I cant find the log file, It is not in the folder I configure.
When I replace the wsgi.py with a hello word file in the same folder It works, so... I dont even know if I am running the right thing.

Any help with the uwsgi to the noob are wellcome. I am reading the docs today and will try harder tomorow.
Thanks.

Actually, at the moment I am using gunicorn for these forums here - it so much easier to use. I'll post my start script as soon as I have access to a computer ;)

start.sh

#!/bin/sh

gunicorn -w 4 wsgi:flaskbb -b 127.0.0.1:30002 --log-file logs/gunicorn.log --reload -D

I stop gunicorn like this:
killall gunicorn
but checkout the gunicorn docs for more options on how to run gunicorn!

and replace the location @flaskbb part with this one:

location @flaskbb {
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
        proxy_set_header Host $http_host;
        proxy_redirect off;
        proxy_buffering off;

        proxy_pass http://127.0.0.1:30002;
    }

I don't want to give nginx support here but you should symlink all the sites you want to have enabled to sites-enabled. The asterisk operator (*) tells nginx that he should include/enable all files in sites-enabled.
btw, shouldn't your server_name be the name of your domain where you want to run flaskbb on?

Here's the uWSGI emperor config for my FlaskBB fork if anyone cares. Some things edited for clarity. Setting up uWSGI and nginx out of scope. 😆

[uwsgi]
chdir = /var/flaskbb
uid = flaskbb
gid = flaskbb
socket = 127.0.0.1:8080
venv = /var/flaskbb/venv/
module = wsgi:flaskbb

Will be testing Tyrant mode later for security reasons.
