run under uwsgi? about flask-appbuilder

[dpgaspar]

On pythonAnywhere i use it like this, you don't actually use run.py on a web server, this is just for development.

import sys

# add your project directory to the sys.path
project_home = u'/home/flaskappbuilder/Flask-AppBuilder-Site'
if project_home not in sys.path:
    sys.path = [project_home] + sys.path

activate_this = '/home/flaskappbuilder/env/bin/activate_this.py'
execfile(activate_this, dict(__file__=activate_this))

# import flask app but need to call it "application" for WSGI to work
from app import app as application

This should be your wsgi.py file. Please check if this works, then report back.

Thank You.

I followed this tutorial:
(https://www.digitalocean.com/community/articles/how-to-deploy-flask-web-applications-using-uwsgi-behind-nginx-on-centos-6-4)
step by step for my fab and it worked fine except for static files ( icons, css, ...) this is my nginx.conf:

---

worker_processes 1;

events {

worker_connections 1024;

}

http {

sendfile on;

gzip              on;
gzip_http_version 1.0;
gzip_proxied      any;
gzip_min_length   500;
gzip_disable      "MSIE [1-6]\.";
gzip_types        text/plain text/xml text/css
                  text/comma-separated-values
                  text/javascript
                  application/x-javascript
                  application/atom+xml;

# Configuration containing list of application servers
upstream uwsgicluster {

    server 127.0.0.1:8080;
    # server 127.0.0.1:8081;
    # ..
    # .

}

# Configuration for Nginx
server {

    # Running port
    listen 80;

    # Settings to by-pass for static files 
    location ^~ /static/  {

        # Example:
        # root /full/path/to/application/static/file/dir;
        root /app/static/;

    }

    # Serve a static file (ex. favico) outside static dir.
    location = /favico.ico  {

        root /app/favico.ico;

    }

    # Proxying connections to application servers
    location / {

        include            uwsgi_params;
        uwsgi_pass         uwsgicluster;

        proxy_redirect     off;
        proxy_set_header   Host $host;
        proxy_set_header   X-Real-IP $remote_addr;
        proxy_set_header   X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header   X-Forwarded-Host $server_name;

    }
}

}

pasted from that tutorial. how to serve static files? thanks.

I have configured it in a different way (no need to change nginx.conf):

First change run.py to this

from app import app

if __name__ == '__main__':
        app.run(host='0.0.0.0')

1 - /etc/nginx/sites-available/mysite

server {
    listen 0.0.0.0:8090;
    server_name _;

location / { try_files $uri @yourapplication; }
location @yourapplication {
      include uwsgi_params;
      uwsgi_pass unix:/tmp/mysite.sock;
    }
}

2 - exec*

ln -s /etc/nginx/sites-available/mysite /etc/nginx/sites-enabled/mysite

3 - /etc/uwsgi/apps-available/myapp.ini*

[uwsgi]
vhost = true
socket = /tmp/mysite.sock
chmod-socket = 666
venv = /home/dpgaspar/workspace/env
chdir = /home/dpgaspar/workspace/quickhowto
module = run
callable = app

4 - exec

sudo ln -s /etc/nginx/sites-available/mysite /etc/nginx/sites-enabled/mysite

5 - exec

sudo touch /tmp/mysite.sock
sudo chown www-data:www-data /tmp/mysite.sock
sudo chmod 666 /tmp/mysite.sock

6 - Restart and watch the logs

sudo service nginx restart
sudo service uwsgi restart
sudo tail -f /var/log/uwsgi/app/myapp.log &
sudo tail -f /var/log/nginx/error.log

[dpgaspar]

Remember: on the above config, change myapp.ini keys chdir and venv to your F.A.B. app venv and directory.

Hope this helps.

I did so ( in FreeBSD 10 ):
1.create a file WSGI.py next to run.py and inside:

---

from app import app
if name == "main":
app.run(host='127.0.0.1', port='8000')

---

2.and in nginx.conf:

---

location / {
include uwsgi_params;
uwsgi_pass 127.0.0.1:8000;
}

---

3.and finaly issued ( insilde activated virtualenv ):
-> uwsgi --socket 127.0.0.1:8000 -w WSGI:app
then it worked as expected ( without extra conf ).

Hi there! I am fighting with this configuration on a Mac and unable to get it working. Any chance of sharing a working recipe? I have other Flask apps working just fine in uWSGI/Nginx, but this one is presenting itself to be quite a challenge. Thanks in advance!

[GregSilverman]

I guess I should be more clear. I am able to get my app working on port 8080, but not on port 80. Other Flask apps run just fine on port 80.

[GregSilverman]

If you want, I can open a new issue.

[GregSilverman]

Never mind, I ran the following uwsgi command in my flask-appbuilder directory: uwsgi -s /tmp/uwsgi.sock -H ./venv/ --chmod-socket=666 --wsgi-file myproject/wsgi.py and all is working on port 80.
