九州云Skyline平台OpenStack私有云部署指南 1. OpenStack与九州云Skyline平台概述OpenStack作为开源云计算管理平台项目已经成为企业私有云建设的首选方案之一。而九州云推出的Skyline发行版则是基于原生OpenStack进行了深度优化和功能增强的企业级解决方案。我在实际部署过程中发现Skyline不仅保留了OpenStack的全部核心功能还在易用性和管理界面上做了显著改进。这个发行版特别适合国内企业环境主要体现在以下几个方面对KVM虚拟化技术的深度调优使得虚拟机性能提升约15-20%集成了符合国内监管要求的运维审计功能提供了本地化的技术文档和社区支持优化了网络组件配置更适合国内网络环境2. 环境准备与系统要求2.1 硬件配置建议根据我的部署经验生产环境的最低硬件配置应该满足控制节点至少16核CPU/64GB内存/500GB SSD系统盘1TB SSDCeph OSD计算节点根据虚拟机密度配置建议每台物理机不低于32核CPU/128GB内存网络节点建议独立部署16核CPU/32GB内存/双万兆网卡特别注意所有节点建议采用相同型号的CPU避免因指令集差异导致虚拟机迁移失败。2.2 操作系统选择与配置九州云Skyline目前官方支持的操作系统版本CentOS 7.9推荐Ubuntu 20.04 LTS麒麟V10国产化需求我以CentOS 7.9为例系统安装后需要执行以下基础配置# 关闭SELinux sed -i s/SELINUXenforcing/SELINUXdisabled/g /etc/selinux/config setenforce 0 # 配置主机名和hosts解析 hostnamectl set-hostname controller echo 192.168.100.10 controller /etc/hosts echo 192.168.100.11 compute01 /etc/hosts # 禁用防火墙后续通过安全组管理 systemctl stop firewalld systemctl disable firewalld3. 九州云Skyline安装流程详解3.1 基础依赖安装首先需要配置OpenStack仓库和EPEL源# 安装EPEL源 yum install -y epel-release # 添加九州云Skyline仓库 cat /etc/yum.repos.d/99cloud.repo EOF [99cloud-openstack-train] name99cloud-openstack-train baseurlhttps://mirrors.99cloud.com/openstack/train/centos7/ enabled1 gpgcheck0 EOF然后安装基础工具包yum install -y python-openstackclient openstack-selinux \ openstack-utils mariadb-server mariadb \ rabbitmq-server memcached python-memcached3.2 数据库与服务配置MySQL数据库配置要点# 启动MariaDB systemctl enable mariadb systemctl start mariadb # 安全初始化 mysql_secure_installation # 创建OpenStack数据库用户 mysql -uroot -p -e CREATE DATABASE keystone;
