OpenStack Object Storage（Swift）を設定します。
ここでは以下のように、Control ノード、Proxy ノード、Storage ノードと、
ノードごとにサーバーを用意して、計5台を使って設定します。

+------------------+ | +-----------------+
| [ Control Node ] |10.0.0.30 | 10.0.0.50| [ Proxy Node ] |
| Keystone |-----------+-----------| |
+------------------+ | +-----------------+
|
+---------------------------+--------------------------+
| | |
|10.0.0.71 |10.0.0.72 |10.0.0.73
+-------+----------+ +--------+---------+ +--------+---------+
| [Storage Node#1] | | [Storage Node#2] | | [Storage Node#3] |
| |-------| |-------| |
+------------------+ +------------------+ +------------------+

ここでは Proxy ノードの設定をします。
|
|
| [1] | Swift-Proxy をインストールします。 |
|
[root@proxy ~]# yum --enablerepo=centos-openstack-mitaka,epel -y install openstack-swift-proxy memcached python-memcached openssh-clients
|
| [2] | Swift-Proxy を設定します。 |
