|
| [1] | Add a user for using Swift on Keystone Control Node. By the way, if you'd like to use Swift Quickly, it's unnecessarry to add a new user, it's posibble to use with existing admin or swift user on Keystone. |

| [2] | Work on a Client from here and later. Install Keystoneclient, Swiftclient on a Client first. |
|
[root@client ~]# yum --enablerepo=centos-openstack-newton,epel -y install python-openstackclient python-keystoneclient python-swiftclient
|
| [3] | Load environment variables first. ( it's just the value for a user added in [1] ) |

[root@client ~]#
