I have installed keystone package in OpenStack., but while starting the keystone service, I am getting error. 
$ service openstack-keystone start
Stopping keystone: [FAILED] 
When I looked at the keystone log, observed the below error recorded
#tailf /var/log/keystone/keystone.log
CRITICAL keystone [-] ConfigFileNotFound: The Keystone configuration file keystone-paste.ini could not be found. 
TRACE keystone Traceback (most recent call last): 
TRACE keystone File "/usr/bin/keystone-all", line 113, in 
TRACE keystone paste_config = config.find_paste_config()
TRACE keystone File "/usr/lib/python2.6/site-packages/keystone/config.py", line 90, in find_paste_config
TRACE keystone raise exception.ConfigFileNotFound(config_file=paste_config_value) 
TRACE keystone ConfigFileNotFound: The Keystone configuration file keystone-paste.ini could not be found
How can I solve this problem?
Thank You
