把不同物理机划分成不同分区 Internal 常见为 openstack 核心程序 develop-zone 供开发同事使用的计算节点集群 qa-zone 供测试同事使用的计算节点集群 |
|
Status |
Up 服务可用 Down 服务不可用 (注, 在集群中, 只能够有一个 nova-console-auth 处于 up 状态) |
|

服务启动时间 |
|
Disable |
手动关闭服务时, 可以添加注释, 注释可在该列中进行显示 |
Zone 说明
由于集群中机器比较多, 申请用户也比较多, 为了更好地进行服务器规划, 我们计划把不同机柜中的服务器划分到不同 zone 中, 并限制不同部门的同事使用不同的 zone.
规划:
开发同事只在 develop-zone 中进行云主机申请
测试同事只在 qa-zone 中进行云主机申请
Sandbox项目只在 sandbox中进行云主机申请
指定申请机器使用使用不同的 zone 方法
