Description Ken Dreyer (Red Hat) 2016-01-28 00:07:34 UTC 
Description of problem:
The calamari web application tries to write to cthulhu.log. This file is owned by root, but the web application is running as an unprivileged Apache UID.

Version-Release number of selected component (if applicable):
Calamari 1.3.2 (Ubuntu and RHEL)

How reproducible:
always

Steps to Reproduce:
1. Install calamari and set up according to instructions
2. Check the web server (http://calamari-node/)

Actual results:
The server returns an HTTP 500 error, and calamari.log indicates that the issue is a permissions problem writing to cthulhu.log.

Expected results:
The web application comes up as expected, and the user can log in

Workaround for RHEL:
sudo chown apache:apache /var/log/calamari/cthulhu.log

Workaround for Ubuntu:
sudo chown www-data:www-data /var/log/calamari/cthulhu.log

After running the chown command, the web app functions as expected.
Comment 1 Tanay Ganguly 2016-01-28 09:00:24 UTC 
I am hitting the same issue.
But even applying the workaround, i am unable to see the Calamari web server.

sudo chown apache:apache /var/log/calamari/cthulhu.log

My setup is being upgraded from 1.3.1 Async to 1.3.2 (26th Build)

[ceph@cephqe4 ceph-config]$ rpm -qa |grep ceph
ceph-common-0.94.5-4.el7cp.x86_64
ceph-deploy-1.5.27.4-1.el7cp.noarch
[ceph@cephqe4 ceph-config]$ rpm -qa |grep calama
calamari-clients-1.3-2.el7cp.x86_64
calamari-server-1.3.2-2.el7cp.x86_64


I am seeing the below Error
