Reboot the system once all the packages are installed and configured
[root@rhosp ~]# reboot

Once the system is back online, log in to the OpenStack GUI and change the default password.
The default password is created in the /root/keystonerc_admin file.

[root@rhops2 ~]# cat /root/keystonerc_admin
unset OS_SERVICE_TOKEN
export OS_USERNAME=admin
export OS_PASSWORD=c4b0a987075b44df
export OS_AUTH_URL=http://10.36.31.90:5000/v2.0
export PS1='[\u@\h \W(keystone_admin)]\$ '
export OS_TENANT_NAME=admin
export OS_REGION_NAME=RegionOne

Follow these procedures:
1. Upon login, update the admin credentials.
2. Click “admin” on the top left corner of the screen.
3. Click “Change Password”

4. Click the “Change” button to submit the password change.
5. Once the password is updated, you will be logged out of the current session immediately.

6. Use the new credentials to log in to the GUI.
7. Once the new password has been updated from the GUI session, update the password in /root/keystone_admin
and save the file.

[root@rhops2 ~]# cat /root/keystonerc_admin
unset OS_SERVICE_TOKEN
export OS_USERNAME=admin
export OS_PASSWORD=<NEW PASSWORD>
export OS_AUTH_URL=http://10.36.31.90:5000/v2.0
export PS1='[\u@\h \W(keystone_admin)]\$ '


export OS_TENANT_NAME=admin
export OS_REGION_NAME=RegionOne


To perform any OpenStack CLI operation, this file needs to be sourced.
[root@rhops2 ~]# source /root/keystonerc_admin
[root@rhops2 ~(keystone_admin)]#

The system will return an error message if the files are not sourced.

[root@rhops2 ~]# neutron port-list
