Question about install support for python and php together

Server NGINX
1

I get a vps host and install php already with spawn-fcgi.
And you could see my steps here:

Now I want to add support python (web.py) in this host,
http://webpy.org/cookbook/fastcgi-nginx
and try the steps in web.py, but can’t work correct.
just get
spawn-fcgi: child exited with: 2

Who could tell me the steps I should do?

Many thanks,

The problem is that FCGI is a bag of crap and anything non-thread safe
will usually crash it. You either have a babysit it with something like
Monit, or use something more modern like uWSGI or Gunicorn. uWSGI is a
wsgi server written in C and needs to be compiled as well as requires a
compiled version of Nginx, although this is recommended anyway because
the Debian Aptitude version of Nginx is so damn old. Gunicorn is a 100%
wsgi server and shares many of the same benefits as uWSGI, but has not
been as fast in my tests. Either of these, your app will be the slow
part, not the wsgi server so it doesn’t matter.

Hope this helps.

I’ve personally had nothing but problems with spawn-fcgi and stopped
using it years ago. The -b switch for the php-cgi config tells PHP to
bind to an address:port, so you don’t really need spawn-fcgi as long as
something can keep an eye on the process.

We use supervisord to spawn & manage both PHP & Python services which
sit behind nginx. A supervisor config with something like the following
should get you going:

[program:PHP]
command=/usr/bin/php-cgi -c /etc/php.ini -b 8888
autostart=true
environment=PHP_FCGI_MAX_REQUESTS=100,PHP_FCGI_CHILDREN=3

[program:MyPythonProgram]
directory=/path/to/my/py/app/dir
command=/usr/bin/python mywsgiapp.py

Then in your nginx config simply create a config file for each FCGI
environment (php/python) and add any “backends” (for python,
specifically) to your vhosts.

You can even use supervisord to start/manage your nginx instance. We
have supervisord manage everything, and have monit keeping an eye on
supervisord as an added bonus.

You can see more on supervisord at http://supervisord.org, however the
site is going through a server move at the moment so they’ve only got
the manual up at the moment.
