パッケージの導入

[root@opst-nova1 ~]# yum install openstack-horizon


設定ファイルの編集

[root@opst-horizon ~]# cd /usr/lib/python2.6/site-packages/openstack_dashboard/local/
[root@opst-horizon local]# cp local_settings.py.example local_settings.py

OPENSTACK_HOST で keystoneのアドレスを編集し、最後のセクションDATABASESを追加する。


起動

ここではhttpd等とは連携させず、直接djangoを起動している。

[root@horizon local]# cd /var/lib/horizon/
[root@horizon horizon]# ./manage.py runserver 0.0.0.0:8000

ブラウザでアクセス。
