<div dir="ltr">I just setup Nginx + uWSGI + Flask the other day for the first time. You're right, the Flask docs on uWSGI are outdated and use deprecated uWSGI commands. There's a pull request in the Flask repo that shows the correct way (as best I could tell) to set things up, it also covers the slightly more complicated scenario of serving multiple Flask apps on a single uWSGI socket.<div><br></div><div>I take a cursory look through your code and nothing stuck out to me... I used the Emperor option in place of the Master process option, as it gives more flexibility, so maybe that's why I'm not seeing the specific issue... maybe try that? </div><div hspace="streak-pt-mark" style="max-height:1px"><img style="width:0px;max-height:0px;overflow:hidden" src="https://mailfoogae.appspot.com/t?sender=aamVmZkBqZWZmd2lkbWFuLmNvbQ%3D%3D&type=zerocontent&guid=0662f0c6-45ac-4a50-98af-87f285e61836"><font color="#ffffff" size="1">ᐧ</font></div></div><div class="gmail_extra"><br><div class="gmail_quote">On Tue, Oct 6, 2015 at 9:03 AM, tigernassau <span dir="ltr"><<a href="mailto:tigernassau@gmail.com" target="_blank">tigernassau@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">we can only get Flask to load on a debian server with nginx, uwsgi with a command line statement, not on server boot - yet we can get bottle to load just fine.<br>
<br>
most of the docs are either outdated, 80% complete, or different combinations (ie gunicorn, mod_wsgi, uwsgi-plugin-python, systemd ...) so we hope to write up a detailed set of docs that work for this combination<br>
<br>
Here's what we have:<br>
nginx.conf<br>
.....<br>
upstream testapp {<br>
server localhost: 8082;<br>
}<br>
.....<br>
location / {<br>
try_files $uri @wsgi;<br>
}<br>
location @wsgi {<br>
include /etc/nginx/uwsgi_params;<br>
uwsgi_pass testapp<br>
}<br>
.....<br>
<br>
/etc/uwsgi/apps-enabled/testapp.ini<br>
[uwsgi]<br>
socket = localhost: 8082<br>
chdir = /home/testapp<br>
file = app.py<br>
master = true<br>
plugins = python<br>
uid = www-data<br>
gid = www-data<br>
vacuum = true<br>
<br>
--- test command line run --- (works!)<br>
sudo uwsgi --socket <a href="http://127.0.0.1:8082" rel="noreferrer" target="_blank">127.0.0.1:8082</a> --wsgi-file /home/testapp/app.py --callable app processes 4 --stats <a href="http://127.0.0.1:9191" rel="noreferrer" target="_blank">127.0.0.1:9191</a><br>
<br>
/etc/systemd/system/testapp.service<br>
[Unit]<br>
Description=wsgi flask testapp<br>
[Service]<br>
ExecStart=uwsgi --socket <a href="http://127.0.0.1:8082" rel="noreferrer" target="_blank">127.0.0.1:8082</a> --wsgi-file /home/testapp/app.py --callable app --processes 4<br>
Restart=always<br>
KillSignal=SIGQUIT<br>
Type=notify<br>
StandardError=syslog<br>
NotifyAccess=all<br>
<br>
[Install]<br>
WantedBy=multi-user.target<br>
<br>
sudo service testapp start ==> error<br>
<br>
The only difference we see between Flask not booting and Bottle working is in the app run statement<br>
Flask:<br>
if __name__ == '__main__':<br>
app.run()<br>
<br>
Bottle:<br>
if __name__ == '__main__':<br>
bottle.run(host="127.0.0.1",port=8082)<br>
else:<br>
app = application = bottle.default_app()<br>
<br>
<br>
maybe app run issue ??<br>
maybe permission issue ?? (but wsgi ini works for bottle)<br>
maybe systemd service file ??<br>
