从本地主机金字塔生活

Question

Hi guys I am having some trouble here and so i'm asking for some advise.

I built a pyramid app, it works perfectly on localhost, now I'm uploading it to a vps and i'm running into all kinds of trouble. My site is hosted on mercurial.

please don't reference this: http://docs.pylonsproject.org/projects/pyramid/en/latest/tutorials/modwsgi/index.html

I've tried that many times and Googled a lot, that's why I'm asking the question here.

I'm on python 2.7

1. I create a virtualenv
2. activate the virtualenv
3. pip -r requirements to download all the requirements
4. then python setup.py install

I now have a folder structure like this:

appname_dir/
     appname_module/
        static/
        template/
        __init__.py
        views.py

keep in mind I didn't name my folders appname_dir and appname_module.

I create my app.wsgi file inside my appname_module folder it looks like this

from pyramid.paster import get_app, setup_logging
ipath = '/path/to/appname_dir/production.ini'
application = get_app(ipath, 'main')

I've tried creating a virtual host file similar to the one below

<VirtualHost *:80>
        ServerAdmin contact@domain.com
        ServerName domain.com
        ServerAlias www.domain.com

        UseCanonicalName On

        WSGIScriptAlias / /path/to/my/app.wsgi
        <Directory /path/to/folder/that/contains/app.wsgi>
                Order allow,deny
                Allow from all
        </Directory>

        Alias /static /path/to/app/static/folder
        <Directory /path/to/app/static/folder>
                Order allow,deny
                Allow from all
        </Directory>
        ErrorLog /path/to/app/folder/logs/error.log
        LogLevel warn
        CustomLog /path/to/app/folder/logs/access.log combined
</VirtualHost>

that doesn't work

I've tried to add custom apache conf file similar to the one below

WSGIApplicationGroup %{GLOBAL}
WSGIPassAuthorization On
WSGIDaemonProcess pyramid user=username group=groupname threads=6 \
   python-path=/path/to/virtualenv/site-packages
WSGIScriptAlias / /path/to/app.wsgi

<Directory /path/to/appname_dir>
  WSGIProcessGroup pyramid
  Order allow,deny
  Allow from all
</Directory>

and still no go. Typically their a 500 error with this code in the apache error log files

Target WSGI script cannot be loaded as Python module

can anyone help explain what's going on or how I can fix this. Please pointing me to other SO answers isn't helpful I've spent all day trying to figure this out.

Answer 1

Well I was able to solve the problem by moving away from apache and mod_wsgi, I setup nginx and uwsgi. If I need apache I can proxy connections from nginx to apache but I don't see me needing to take that route anytime soon.
