Re: [web2py] Configuring web2py with nginx - domain error ("gaierror: [Errno -2] Name or service not known")
Carlos,
Maybe better to post a new thread if it is important and link to this one
if requires.

It seems like what's happening is that web2py is receiving the http;//

socket.gethostbyname() chokes on that. Is there something I should be
changing in the configuration to prevent this from happening?

Re: [web2py] Configuring web2py with nginx - domain error ("gaierror: [Errno -2] Name or service not known")
HI,
I just saw this error in my server log, just once, with the following entry:
ERROR:web2py:Traceback (most recent call last):
File "/home/www-data/web2py/gluon/main.py", line 401, in wsgibase
socket.gethostbyname(http_host)]
gaierror: [Errno -2] Name or service not known
So far it is just that one occurrence (and not from a web request generated
by me).
And so far all web requests from my end work ok.
Should I act on it somehow?.
I'm using latest web2py trunk, with ubuntu 10.04, postgresql, nginx,
uwsgi-python.
Thanks,
Carlos

Re: [web2py] Configuring web2py with nginx - domain error ("gaierror: [Errno -2] Name or service not known")
I wrote a patch to fix the problem on my server, which is basically just
commenting out that line (main.py:390ish):
local_hosts =
[http_host,'::1','127.0.0.1',':::127.0.0.1']
if not global_settings.web2py_runtime_gae:
local_hosts += [socket.gethostname()]
#socket.gethostbyname(http_host)]
It looks like that line is just to check for the request is coming from the
externally facing IP. Could that perhaps be wrapped in a try-catch block
and the results cached?
Thanks,
Chris

Re: [web2py] Configuring web2py with nginx - domain error ("gaierror: [Errno -2] Name or service not known")
I don't know if you have any constrain, but for testing purpose you can use
nginx setup script in web2py/scripts folder... There is one for ubuntu at
least...

[web2py] Configuring web2py with nginx - domain error ("gaierror: [Errno -2] Name or service not known")
I'm using web2py with nginx, and I've experienced the following error
on redeploying my app:
socket.gethostbynamesocket.gethostbyname(http_host) File "/var/
web2py/cow/gluon/main.py", line 396, in wsgibase
socket.gethostbyname(http_host)]
gaierror: [Errno -2] Name or service not known
I traced this down to a particular section in gluon/main.py:
local_hosts = [http_host,'::1','127.0.0.1',':::
127.0.0.1']
if not global_settings.web2py_runtime_gae:
local_hosts += [socket.gethostname(),
socket.gethostbyname(http_host)]
As it turns out, http_host (the value above) is mapped to the
nginx.conf value for http_host:
upstream custom_server_name {
server 127.0.0.1:8000;
}
It seems like what's happening is that web2py is receiving the http;//
custom_server_name instead of http://localhost, and
socket.gethostbyname() chokes on that. Is there something I should be
changing in the configuration to prevent this from happening?
