2.4. 使用相同的网络配置和部署每个单元堆栈

流程

1. 为新单元创建一个新目录：

   (undercloud)$ mkdir cells

2. 为单元目录（cells）中每个额外单元创建一个新的环境文件，用于特定于单元的参数，例如 /cells/cell1.yaml。

3. 为每个环境文件添加以下参数，更新部署中每个单元的参数值：

   parameter_defaults:
     # Disable network creation in order to use the `network_data.yaml` file from the overcloud stack,
     # and create ports for the nodes in the separate stacks on the existing networks.
     ManageNetworks: false
   
     # Specify that this is an additional cell
     NovaAdditionalCell: True
   
     # The DNS names for the VIPs for the cell
     CloudName: cell1.ooo.test
     CloudNameInternal: cell1.internalapi.ooo.test
     CloudNameStorage: cell1.storage.ooo.test
     CloudNameStorageManagement: cell1.storagemgmt.ooo.test
     CloudNameCtlplane: cell1.ctlplane.ooo.test

4. 使用其他环境文件将环境文件添加到堆栈中，并部署单元堆栈：

   (undercloud)$ openstack overcloud deploy --templates \
    --stack cell1 \
    -e [your environment files] \
    -e /home/stack/templates/overcloud-baremetal-deployed.yaml \
    -e /home/stack/templates/overcloud-networks-deployed.yaml \
    -e /home/stack/templates/overcloud-vip-deployed.yaml \
    -r $HOME/common/cell_roles_data.yaml \
    -e $HOME/common/default_cell_export.yaml \
    -e $HOME/cells/cell1.yaml

   Copy to Clipboard Toggle word wrap

   为每个单元堆栈重复此步骤，直到部署所有单元堆栈。
