[web2py] Re: problem with multiple processes with uwsgi and web2py

[VP]

I also test uwsgi serving a Bottle app.  I run from the command line, 
uwsgi, the bottle app with 8 processes.


This works as I expect.   Requests are served by unbusy processes while 
long-running requests are still being run.


So something about the web2py configuration that doesn't tell uwsgi to run 
with multiple processes.

Does anyone have any clue?

Thanks.

Is that the file created by the script?. uwsgi can take options in 
different ways. Make sure it is actually reading the options from there. 
For example, the CentOS script creates a .conf file

Alan,
No.  From the command line, I told uwsgi to run with 8 processes (for the 
Bottle app).  Here's the command:

uwsgi --http 127.0.0.1:8080 -p 8 --plugins python --module=app:application

[VP]

Those who are running nginx, uwsgi, web2py, can you do a quick check to see 
if uwsgi reads your web2py config file properly?

The default config has 4 processes.  If you do a top -u www-data, you 
should see 5 uwsgi processes (4 + 1 master).

If you see a different number (may be 3?), then there might be a problem.

Thanks.

[Bruno Rocha]

I have a single server, ubuntu 12.04 running 3 web2py instances + 2 php
wordpress websites

Php runs with fcgi - web2py runs with uwsgi, because of that I have 12
nginx workers running

I am not an expert on this, but this solution is working well for me.


That is what I have in top

Re: [web2py] Re: problem with multiple processes with uwsgi and web2py

[VP]

Thanks Bruno.

Okay, I figured it out.  I'm not sure if I used an out-of-date 
web2py/uwsgi/ngninx install script, but that script does not mention 
another file /usr/share/uwsgi/conf/default.ini 

This file sets the number of workers to 2 and it overwrites the web2py 
configuration file /etc/uwsgi/apps-available/web2py.xml

and youi delete or comment that file?

Re: [web2py] Re: problem with multiple processes with uwsgi and web2py

[VP]

yeah.  I commented off the worker=2 setting in that file.  Consequently, 
the number of workers was exactly what the web2py configure file says.

Ok, but just read this
