[ckan-dev] Internal Server Error while adding dataset

[Jason Tan]

HI Bhavesh,

I'm' just taking a a guess here based on the limited info we've got and my
very limited experience

The most common problems I have noticed with CKAN in my very limited
experience are CKAN not being able to talk to the database (e.g. database
server has been rebooted but the db did not come up or a firewall rule was
reloaded or a network interface somewhere is broken) or permissions on a
directory on the ckan server.
E.g. the ofs.storage_dir not being writable by the web server user

If you're getting webserver errors, it would be really useful to include
web server error log output.
Often the error is fairly easy to decipher from log output.

Not sure how experienced you are in this space i.e running apps on unix
hosts, but I'd be looking at my system log e.g. /var/log/messages, the
webserver error logs e.g. /var/log/apache/error_log
 /var/log/apache/ssl_error_log  (the paths will vary from distro to distro
- I'ma redhat guy so those are centos/redhat paths) and running the dmesg
command.

Also if you are running a distro with selinux  (most redhat based distros
have it) try typing: getenforce which will tell you if selinux is enforcing
its policy or not.

If it says enforcing then try temporarily turning it off by running the
following as root:
setenforce 0

Usually when something goes wrong there are hints in these kinds of places
and it is useufl for you to chceck them and if you ask for help to inlcude
any possibly related messages in your help request.

I believe you can also add logging to CKAN itself while it is running under
paster, though I can't recall how to do it.

Regards
Jason Tan
