5.3. 集成外部 Ceph

查找 stackrc 文件：

[stack@director ~]$ source ~/stackrc

生成环境文件 ~/central/central-images-env.yaml

sudo openstack tripleo container image prepare \
-e containers.yaml \
--output-env-file ~/central/central-images-env.yaml

在主目录中，为您计划部署的每个堆栈创建目录。使用它来分隔为各自站点设计的模板。将中央位置的 network_data.yaml、vip_data.yaml 和 overcloud-baremetal-deploy.yaml 模板移到 /home/stack/central/。

mkdir /home/stack/central
mkdir /home/stack/dcn0
mkdir /home/stack/dcn1

mv network_data.yaml /home/stack/central
mv vip_data.yaml /home/stack/central
mv overcloud-baremetal-deploy.yaml /home/stack/central

调配 overcloud 的网络。此命令取 overcloud 网络的定义文件作为输入。您必须使用命令中的输出文件来部署 overcloud：

openstack overcloud network provision \
--output /home/stack/central/overcloud-networks-deployed.yaml \
/home/stack/central/network_data.yaml

为 overcloud 调配虚拟 IP。此命令取虚拟 IP 的定义文件作为输入。您必须使用命令中的输出文件来部署 overcloud：

openstack overcloud network vip provision \
--stack central \
--output /home/stack/central/overcloud-vip-deployed.yaml \
/home/stack/central/vip_data.yaml

置备裸机实例。该命令为裸机节点使用一个定义文件作为输入。您必须使用命令中的输出文件来部署 overcloud：

openstack overcloud node provision \
--stack central \
--network-config \
-o /home/stack/central/deployed_metal.yaml \
/home/stack/central/overcloud-baremetal-deploy.yaml

在 site-name.yaml 环境文件中配置站点的命名约定。Compute (nova)可用区和 Block Storage (cinder)可用区必须匹配：

cat > /home/stack/central/site-name.yaml << EOF
parameter_defaults:
    NovaComputeAvailabilityZone: central
    ControllerExtraConfig:
        nova::availability_zone::default_schedule_zone: central
    NovaCrossAZAttach: false
    CinderStorageAvailabilityZone: central
    GlanceBackendID: central
EOF

使用类似如下的内容配置 external-ceph.yaml 模板：

parameter_defaults:
    CinderEnableIscsiBackend: false
    CinderEnableRbdBackend: true
    CinderEnableNfsBackend: false
    NovaEnableRbdBackend: true
    GlanceBackend: rbd
    GlanceBackendID: central
    GlanceEnabledImportMethods: web-download,copy-image
    GlanceStoreDescription: 'central rbd glance store'
    CinderRbdPoolName: "openstack-cinder"
    NovaRbdPoolName: "openstack-nova"
    GlanceRbdPoolName: "openstack-images"
    CinderBackupRbdPoolName: "automation-backups"
    GnocchiRbdPoolName: "automation-metrics"
    CephClusterFSID: 38dd387e-837a-437c-891c-7fc69e17a3c
    CephClusterName: central
    CephExternalMonHost: 10.9.0.1,10.9.0.2,10.9.0.3
    CephClientKey: "AQAKtECeLemfiBBdQp7cjNYQRGW9y8GnhhFZg=="
    CephClientUserName: "openstack

部署中央位置：

openstack overcloud deploy \
--stack central \
--templates /usr/share/openstack-tripleo-heat-templates/ \
-n /home/stack/central/network-data.yaml \
...
-e /usr/share/openstack-tripleo-heat-templates/environments/network-environment.yaml \
-e /usr/share/openstack-tripleo-heat-templates/environments/external-ceph.yaml \
-e /usr/share/openstack-tripleo-heat-templates/environments/nova-az-config.yaml \
-e /home/stack/central/overcloud-networks-deployed.yaml \
-e /home/stack/central/overcloud-vip-deployed.yaml \
-e /home/stack/central/deployed_metal.yaml \
-e /home/stack/central/external-ceph.yaml \
-e /home/stack/central/overcloud-networks-deployed.yaml \
-e /home/stack/central/central_roles.yaml

为中央位置部署 overcloud 后，导出边缘站点的额外堆栈部署的输入数据并将其放置在 /home/stack/overcloud-deploy 目录中。确保存在此 control-plane-export.yaml 文件：

stat ~/overcloud-deploy/control-plane/control-plane-export.yaml

创建名为 central_ceph_external.yaml 的环境文件，其中包含有关 Red Hat Ceph Storage 部署的详细信息。此文件可以传递给边缘站点的额外堆栈部署。
