Getting internal error for graphite

What version of Graphite you trying to install? and what's Django version do you have?

PS: For Graphite 1.0.x wsgi can be very simple - https://github.com/graphite-project/graphite-web/blob/master/conf/graphite.wsgi.example, .e.g.

import sys
sys.path.append('/opt/graphite/webapp')
from graphite.wsgi import application

Hi Denis

Just use simple wsgi file which I posted above.

Thank you for your response.

We are already using same same.

Ah, true.
django.utils.importlib was deprecated in django 1.9, but looks like your code still using old version oj django. try to remove all versions of django except 1.9

Thank you for response.

I can see only one Django==1.9.9 in the system.

Could you please help me to find out other version in the system.

Could you please some one help on this.. really appreciated..

Remove old fine (/opt/graphite/webapp/graphite/wsgi.py) and try again.

Hi Deniz

After removing the file same repose.

[root@XX webapp]# rm /opt/graphite/webapp/graphite/wsgi.py
rm: remove regular file `/opt/graphite/webapp/graphite/wsgi.py'? y
[root@icingamonitoringdr webapp]#

Still getting error

How you can get error in line 7 of non-existing File "/opt/graphite/webapp/graphite/wsgi.py" ?

Seems to be something else having the issue.

after rebooting the server.. it is saying site can't be reached.

Hi Denis,

Could you please cross check the file "/etc/httpd/conf.d/graphite.conf" mentioned above.

Looks sane. You need to remove 'Alias /media/ "@DJANGO_ROOT@/contrib/admin/media/"' line, but it should not bring any troubles.

We removed the file and tried..
still getting same issue in the error log

Sorry, rocky, but this lines are old - from September 26. I'm really doubt that non-existing file can give you this error, especially after server reboot. Please check fresh errors.

ok sure...
 Same error.. that is the reason copied for the above line..
Let me share the fresh error log.

Sorry, rocky, I ran out of ideas. You should remove file /opt/graphite/webapp/graphite/wsgi.py and restart webserver - error should gone. If it's not - probably you're checking wrong server, or something else is seriously wrong.

Thank you for response.

Found something .. let me share with you..

How to load the module with python version 2.7 ?

You should install proper mod_wsgi module, which build against python 2.7
It depends where do you get python 2.7
If you installed that from 3rd party repo - it's better to pick up mod_wsgi package also there.
if you install python from sources - then you need to build mod_wsgi also from sources, as described for example here - https://blog.webhostpython.com/how-to-install-python-2-7-with-mod_wsgi-on-a-centos-6-vps-or-server-with-cpanel/

Thank you for the update..
