Hello, I am trying to install Openstack *liberty* version on *Centos7*. I am stucked while installing Identity service creation. I have searched google for the solution but could not find one!
My admin-openrc.sh contains: export OS_PROJECT_DOMAIN_ID=default export OS_USER_DOMAIN_ID=default export OS_PROJECT_NAME=os_demo export OS_TENANT_NAME=admin export OS_USERNAME=admin export OS_PASSWORD=password export OS_AUTH_URL=http://controller:35357/v3 <http://10.0.0.11:35357/v3> export OS_IDENTITY_API_VERSION=3 export OS_IMAGE_API_VERSION=2 Command tried is: # openstack service create --name keystone --description "OpenStack Identity" identity --os-username admin --os-auth-url http://controller:35357/v3 <http://10.0.0.11:35357/v3> --os-project-name os_demo Output--> *Discovering versions from the identity service failed when creating the password plugin. Attempting to determine version from URL.* *Internal Server Error (HTTP 500)* When I check the file /var/log/httpd/keystone-error.log, I noticed these lines: mod_wsgi (pid=56573): Target WSGI script '/usr/bin/keystone-wsgi-admin' cannot be loaded as Python module. 2016-02-02 18:08:40.864117 mod_wsgi (pid=56573): Exception occurred processing WSGI script '/usr/bin/keystone-wsgi-admin'. 2016-02-02 18:08:40.864132 Traceback (most recent call last): 2016-02-02 18:08:40.864144 File "/usr/bin/keystone-wsgi-admin", line 36, in <module> 2016-02-02 18:08:40.864165 application = initialize_admin_application() 2016-02-02 18:08:40.864171 File "/usr/lib/python2.7/site-packages/keystone/server/wsgi.py", line 78, in initialize_admin_application 2016-02-02 18:08:40.864182 return initialize_application('admin') 2016-02-02 18:08:40.864188 File "/usr/lib/python2.7/site-packages/keystone/server/wsgi.py", line 51, in initialize_application 2016-02-02 18:08:40.864197 common.configure() 2016-02-02 18:08:40.864203 File "/usr/lib/python2.7/site-packages/keystone/server/common.py", line 31, in configure 2016-02-02 18:08:40.864212 config.configure() 2016-02-02 18:08:40.864218 File "/usr/lib/python2.7/site-packages/keystone/common/config.py", line 1204, in configure 2016-02-02 18:08:40.864228 help='Do not monkey-patch threading system modules.')) 2016-02-02 18:08:40.864234 File "/usr/lib/python2.7/site-packages/oslo_config/cfg.py", line 1828, in __inner 2016-02-02 18:08:40.864243 result = f(self, *args, **kwargs) 2016-02-02 18:08:40.864249 File "/usr/lib/python2.7/site-packages/oslo_config/cfg.py", line 2003, in register_cli_opt 2016-02-02 18:08:40.864258 raise ArgsAlreadyParsedError("cannot register CLI option") 2016-02-02 18:08:40.864272 ArgsAlreadyParsedError: arguments already parsed: cannot register CLI option Please help me get out of this issue. I have other queries mentioned below: 1. I see an example of 2-node architecture in the installation guide for liberty version. Which guide do I have to refer to have 3-node architecture (Node1 being Controller, Node2 as Nuetron and Node3 as a compute)? Thanks, Basavaraj
