OpenStack Object Storage(Swift)の設定です。
ここでは以下のように、認証ノード、プロキシノード、ストレージノードと、 ノードごとにサーバーを用意して、計5台を使って設定してみることにします。

ここではプロキシノードの設定をします。
[1] Swift-Proxy インストール
# EPEL OpenStack, EPELからインストール

[root@proxy ~]#
yum --enablerepo=openstack-havana,epel -y install openstack-swift-proxy memcached openssh-clients
[2] Swift-Proxy 設定
[root@proxy ~]#
vi /etc/swift/proxy-server.conf
# 30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

admin_user =
swift

admin_password =
servicepassword

auth_host =
10.0.0.30

auth_port = 35357
auth_protocol = http
signing_dir = /tmp/keystone-signing-swift
[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
[root@proxy ~]#
mkdir /tmp/keystone-signing-swift

[root@proxy ~]#
chown swift. /tmp/keystone-signing-swift
