红帽全球峰会9.8. 为预置备节点配置 Ceph Storage
在 undercloud 主机上完成以下步骤，为已部署的节点配置 ceph-ansible。
步骤
在 undercloud 主机上，创建环境变量
OVERCLOUD_HOSTS，并将该变量设置为您要用作 Ceph 客户端的 overcloud 主机的 IP 地址列表（以空格分隔）：export OVERCLOUD_HOSTS="192.168.1.8 192.168.1.42"
Copy to clipboardCopiedexport OVERCLOUD_HOSTS="192.168.1.8 192.168.1.42"运行
enable-ssh-admin.sh脚本，以在 Ansible 可用于配置 Ceph 客户端的 overcloud 节点上配置用户：bash /usr/share/openstack-tripleo-heat-templates/deployed-server/scripts/enable-ssh-admin.sh
Copy to clipboardCopiedbash /usr/share/openstack-tripleo-heat-templates/deployed-server/scripts/enable-ssh-admin.sh
运行 openstack overcloud deploy 命令时，Ansible 配置您在 OVERCLOUD_HOSTS 变量中定义为 Ceph 客户端的主机。
