[2] | This is Client's settings. Install Keystoneclient, Swiftclient first. |
# install from EPEL OpenStack, EPEL [root@client ~]# yum --enablerepo=openstack-havana,epel -y install python-keystoneclient python-swiftclient
|
[3] | Load environment variables first. ( it's just the value for a user added in [1] ) |
[root@client ~]#
