2015/06/20
 
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     |-----------+-----------|                 |
     +------------------+           |           +-----------------+

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。
# RDO, EPEL からインストール

[root@proxy ~]#
yum --enablerepo=openstack-kilo,epel -y install openstack-swift-proxy memcached openssh-clients
[2] Swift-Proxy を設定します。
[root@proxy ~]#
vi /etc/swift/proxy-server.conf
# 53行目:以下のように変更 (認証ノードの Keystone に登録した値)

[filter:authtoken]
paste.filter_factory = keystoneclient.middleware.auth_token:filter_factory
#
admin_tenant_name = %SERVICE_TENANT_NAME%
#
admin_user = %SERVICE_USER%
#
admin_password = %SERVICE_PASSWORD%
#
#
identity_uri = http://localhost:35357/
#
auth_uri = http://localhost:5000/
#
signing_dir = /tmp/keystone-signing-swift
auth_uri = http://10.0.0.30:5000
auth_url = http://10.0.0.30:35357
auth_plugin = password
project_domain_id = default
user_domain_id = default
project_name = service
username = swift
password = servicepassword
delay_auth_decision = true
[root@proxy ~]#
vi /etc/swift/swift.conf
# 以下のように変更 (Swiftノード間でシェアする値 - 適当な文字列でよい)

[swift-hash]
swift_hash_path_suffix =
swift_shared_path
[3] Swift Ring ファイルの設定です。
