This section shows how to use Swift Storage from Clients.
This example is based on the emvironment like follows.
-+---------------+----------------------------+----------------------------+------------

| eth0|10.0.0.30 eth0|10.0.0.50 eth0|10.0.0.61
| +-----------+-----------+ +-----------+-----------+ +-----------+-----------+
| | [ Control Node ] | | [ Proxy Node ] | | [ Client ] |
| | | | | | |
| | MariaDB RabbitMQ | | Swift Proxy | | Swift Client |
| | Memcached httpd | | | | |
| | Keystone | | | | |

| [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:~# apt-get -y install python-keystoneclient python-swiftclient
|
| [3] | Load environment variables first. ( it's just the value for a user added in [1] ) |

root@client:~#
vi ~/keystonerc_swift

export OS_USER_DOMAIN_NAME=default export OS_PROJECT_NAME=swiftservice export OS_USERNAME=user01 export OS_PASSWORD=userpassword export OS_AUTH_URL=http://10.0.0.30:35357/v3 export OS_IDENTITY_API_VERSION=3 export PS1='[\u@\h \W(swift)]\$ '
