篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了Kolla OpenStack相关的知识，希望对你有一定的参考价值。
多节点部署
目录
- 业务场景
- 多节点的规划（2）
- 网络规划与拓扑
- 管理节点的配置
- 部署
- 物理机部署
业务场景
- 适合节点规模在3-5个左右。
- 没有管理节点的高可用，没有ssd（没有万M网络），不用ceph。
- 主要跑些测试或hadoop应用等。
多节点的配置
- Kolla部署+一个管理（3c/6g）、一个计算(3c/8g)
- 创建vm，安装系统（可以从base克隆，然后调整配置）
- 修改虚拟机配置信息
网络拓扑
- 主机名
- IP地址
- 解析（/etc/hosts）
- 10.99.0.2 control01
- 10.99.0.3 compute01
