Re: Flask app as UWSGI returning 500 when accessed through OpenBSD HTTPD

[Kamil Cholewiński]

I Am Not A uWSGI Expert, but the way we've been usually setting it up is
via plain HTTP reverse proxying, never CGI/FastCGI. I would try that
approach first.

I am now able to create the socket with correct permission / ownership.
Here is the uwsgi ini file -

[uwsgi]
module = wsgi
# process related settings
master = 1
processes = 4
threads = 2

socket = /var/www/run/hello.sock
# approprite ownership and permissions on socket
chmod-socket = 660
chown-socket = www:www

# clear environment on exit
vaccume = true
wsgi-file = myproject.py

and I am running it as -

$ doas uwsgi --ini hellopy.ini --callable app

and this is the permissions now -

$ ls -l /var/www/run
total 0
srw-rw  1 www  www  0 Oct 18 19:47 hello.sock=

Now when I access

http://192.168.1.111/hello/

request just times out (return code 408)

access.log just shows -

default x.y.a.b - - [18/Oct/2017:19:48:41 +0530]" " 408 0

There is nothing in error.log

Any idea what am I doing wrong.

Regards.

Yes, I see that. Thank you very much. I will try and figure out on how do I
make uwsgi create socket with specific ownership and permissions. I would
hate to chroot the uwsgi because that would mean to copy python libraries
in /var/www :-)

Thanks again for inputs here.

And voila, they are wrong. How would httpd daemon be able
to write there?

See what slowcgi, a fastcgi->cgi daemon says about socket:

  slowcgi opens a socket at /var/www/run/slowcgi.sock, owned by www:www,
  with permissions 0660.  It will then chroot(8) to /var/www and drop
  privileges to user "www".

See?

Here are the perms -

srwxr-xr-x  1 root  daemon  0 Oct 18 13:35 hello.sock

Nothing is in the error log. The access log indicates one line with 500 in
it.

Any pointers will be helpful.


hi, what's in your error.log?

Can httpd access the socket? What are permissions?

[Ajitabh Pandey]

Thanks for the quick response. I tried that, still getting 500 the same
problem -

$ doas uwsgi --socket /var/www/run/hello.sock --wsgi-file myproject.py
--master --callable app

In /etc/httpd.conf -

  location "/hello/*" {
fastcgi socket "/run/hello.sock"
  }

Regards.

Flask app as UWSGI returning 500 when accessed through OpenBSD HTTPD

[Ajitabh Pandey]

Hi,

I am trying to setup a sample flask application proxy through OpenBSD
httpd. Here is the config -

--
ext_ip="192.168.1.111"

prefork 2

server "default" {
  listen on $ext_ip port 80
  root "/htdocs"

  location "/hello/*" {
fastcgi socket ":"
  }
}

types {
  text/csscss
  text/html   html htm
  text/plain  txt
  image/gif   gif
  image/jpeg  jpeg jpg
  image/png   png
  application/javascript  js
  application/xml xml
}
--

The flask app is

--
from flask import Flask
app = Flask(__name__)

@app.route("/")
def hello():
return "Hello There!"

if __name__ == "__main__":
app.run(host='127.0.0.1')

I am running UWSGI as -
--

$ uwsgi --http : --wsgi-file myproject.py --master --callable app

$ curl http://127.0.0.1:/

returns the contents, but when I access the page as

http://192.168.1.111/hello/

I get 500.

Any pointers will be helpful.

Regards.
