[web2py] Re: Webfaction Deployment and Tuning Web2py Slice.

[HittingSmoke]

How do you do this on Webfaction (use web2py/uwsgi with the native nginx 
instance)? I've asked for this specifically and been told by Webfaction 
staff that it's not actually possible to use a framework with the native 
nginx instance, only with static and PHP apps.

Right now I'm using a custom nginx/uwsgi install script.

I'm certainly no expert, but I'm also on webfaction and you may want to 
consider using nginx/uwsgi. At least in my case, there was very little I 
needed to worry about in terms of configuration/memory management. Just two 
tricks:

- no need to install nginx, as you can just use webfaction's nginx instance 
(there is a recipe floating around that has you build/install a local copy. 
there may be some advantages to this, but I found it to be unnecessary)
- make sure to use uwsgi's "reload-on-rss" option to make sure the process 
doesn't keep consuming more and more memory - webfaction kill your 
processes if you go over your limit. There's a number of posts on this 
topic in this forum.

In general, it's a fast server and relatively straightforward set up. Might 
be more suitable for your needs than fiddling with apache config files.

[web2py] Re: Webfaction deployment

[mdipierro]

of course ;-)

appadmin sets

session.secure()

which turns the session cookie into a secure cookie and it cannot go
over http, only https.

You can disable this by commenting session.secure() in appadmin.py

webfaction day2: the auto-logout problem and why


Many coincidence lead to the "auto-logout (lost session)" problem.
Here is a how-to which you shall not follow. :-)

Problem: Even the web2py welcome app on webfaction tends to ask me to
re-login often, due to something is wrong with the session.

How to reproduce the problem:

1. Follow the official "latest stable source" install script [1] to
setup web2py as normal.

2. Setup an http site for normal use, and an httpS site for admin. And
as usual, both sites map "/" as URL path to the same web2py instance.

3. Due to lack of domain resource at the beginning, I setup both sites
with the same only domain I have, MY_ACCOUNT.webfactional.com.  (This
is coincidence 1. I should better use different domain names, such as
www.top_level_domain.com for normal site, and
admin.top_level_domain.com for the admin site.) (And, later I know
that I can use the ip string as a second domain, to avoid all later
problem.)

4. Visit http://MY_ACCOUNT.webfactional.com/welcome/default/index ,
register a new web2py welcome account, then login, you will see a
"Welcome your_first_name" at the upper-right corner.

5. Use SAME browser, open a new tab, to visit
https://MY_ACCOUNT.webfactional.com/appadmin/index, page shows up
fine. (This is coincidence 2. If I use another browser to open a new
window hence a new session, I should be fine.)

6. At this moment, the session file is somehow replaced, so when you
use your same browser to visit 
http://MY_ACCOUNT.webfactional.com/welcome/default/index
, you will notice you have been automatically logout.

Now you see, two coincidence together lead to the auto-logout problem.
No wonder few webfaction-web2py users met same problem. But it did
cost me several hours to trace down the culprit. What a day2 lesson in
my webfactoin life. :-/

One more big problem, my app on webfaction keeps asking me to re-login
within every few minutes.  Why is that?  @_@

Anybody who is using webfaction can share some info?

Thanks

I used to think webfaction's one-click installer would be handy for
noob like me. Turns out its apache conf is quite different than the
one suggested in http://web2py.com/book/default/chapter/11#mod_wsgi

The webfaction apache http.conf is as below.
