OpenStack Image Service(Glance)をインストールします。 当例では以下のような環境に Glance をインストールします。 eth0|10.0.0.30 +-----------+-----------+ | [ dlp.srv.world ] | | (Control Node) | | | | MariaDB RabbitMQ | | Memcached Nginx | | Keystone httpd | | Glance | +-----------------------+ |
[1] | Keystone に Glance 用のユーザー等々を作成しておきます。 |

[2] | Glance 用のユーザーとデータベースを MariaDB に作成しておきます。 |

[3] | Glance をインストールします。 |
[root@dlp ~(keystone)]# dnf --enablerepo=centos-openstack-caracal,epel,crb -y install openstack-glance
|
[4] | Glance の基本設定です。 |
[root@dlp ~(keystone)]# mv /etc/glance/glance-api.conf /etc/glance/glance-api.conf.org

[5] | Nginx にプロキシの設定をします。 SSL/TLS 証明書を取得は Apache httpd Keystone と同じ証明書を指定します。 |
[root@dlp ~(keystone)]#
