一直想学习下openstakc的源代码，期间用packstack安装成功过，但是devstack一直安装失败，终于在试验了很多次之后，终于成功了！踩坑无数。。。环境准备： centos7.3.1611最小化安装（16G内存、60G硬盘、因为直接在服务器上开虚拟机测试的，内存调到比较大，目测4G以上应该都没问题） devstack版本：newton openstack版本

总结 正确看待OpenStack、KVM、Docker的方式应该是： OpenStack用于管理整个数据中心，KVM和Docker作为相应的补充，KVM用于多租户的计算资源管理，Docker Container用于应用程序的打包部署。正确看待OpenStack、KVM、Docker的方式应该是： OpenStack用于管理整个数据中心，KVM和Docker作为相应的补充，KVM用于多租户的计算资源管理，Docker Container用于应用程序的打包部署。通过QQ浏览器打开后，可直接查看。

centos7 安装 openstack
最新发布

<think>好的，我需要帮助用户在CentOS 7上安装OpenStack的最新稳定版。根据用户提供的引用内容，我需要先整理现有的信息，并补充可能缺失的步骤。 首先，引用[3]提到CentOS下安装OpenStack的硬件要求，比如内存至少8GB，建议16GB，CPU四核，硬盘80GB以上，网络桥接模式。这些是安装前的必要条件，必须确保用户的环境符合。 引用[2]和[4]都涉及CentOS7安装OpenStack的教程，但用户需要的是最新稳定版。然而，引用[1]指出，从Ussuri版本开始，OpenStack不再支持Python2，而CentOS8默认使用Python3。但用户希望继续在CentOS7上安装，这可能存在兼容性问题，因为CentOS7默认的Python版本是2.7，而最新OpenStack版本可能需要Python3。不过，根据引用[4]，用户手动搭建了T版（即Train版本），可能说明在CentOS7上仍可行，但需要处理Python环境。 接下来，我需要确定如何在CentOS7上安装最新稳定版。但根据OpenStack的官方文档，最新的版本可能已经不再支持CentOS7，需要确认。例如，Victoria版本可能需要CentOS8。但用户引用的资料中有在CentOS7上安装T版（Train）的例子，所以可能用户需要安装较旧的稳定版，或者找到适配CentOS7的方法。 因此，安装步骤可能包括： 1. 环境准备：硬件、网络配置，安装必要依赖。 2. 配置仓库：可能使用RDO或Packstack。 3. 安装Packstack工具。 4. 生成应答文件，调整配置（如网络设置）。 5. 运行安装命令。 6. 验证安装。 需要提醒用户CentOS7可能无法安装最新版本，建议升级到CentOS8，但若坚持使用CentOS7，可能需要选择较旧的OpenStack版本，如Train或Ussuri，并处理Python依赖问题。同时，引用[1]提到Packstack在CentOS8.2成功安装Victoria，但CentOS7可能需要不同步骤。 可能的问题：如何在CentOS7上处理Python3依赖？可能需要安装Python3.6及以上，并配置虚拟环境。此外，网络配置部分需要指导Neutron的设置，如引用[4]提到的网络服务。 最后，生成相关问题需要考虑用户可能遇到的后续问题，如版本兼容性、网络配置、故障排除等。</think>### 在 CentOS 7 上安装 OpenStack 最新稳定版指南 虽然 OpenStack 最新版本（如 *Victoria* 或 *Wallaby*）官方推荐使用 CentOS 8 或更高版本[^1]，但通过手动配置仍可在 CentOS 7 上安装较新的稳定版（如 *Train* 或 *Ussuri*）。以下是具体步骤： --- #### **1. 环境准备** - **硬件要求**：内存 ≥8GB（建议 16GB）、CPU 四核、硬盘 ≥80GB、网络桥接模式[^3]。 - **系统配置**： ```bash # 关闭防火墙和 SELinux systemctl stop firewalld systemctl disable firewalld setenforce 0 sed -i 's/SELINUX=enforcing/SELINUX=disabled/g' /etc/selinux/config # 安装依赖 yum install -y centos-release-openstack-train # 选择 Train 版本仓库 yum upgrade -y ``` --- #### **2. 安装 Packstack 工具** Packstack 是快速部署 OpenStack 的自动化工具。 ```bash yum install -y openstack-packstack ``` --- #### **3. 生成应答文件并配置** 生成默认应答文件并修改关键参数： ```bash packstack --gen-answer-file=answer.txt ``` 编辑 `answer.txt`： - 设置网络接口（如 `CONFIG_NEUTRON_OVS_BRIDGE_IFACES=br-ex:eth0`）[^4] - 配置管理员密码（`CONFIG_KEYSTONE_ADMIN_PW`） - 启用必要服务（如 Neutron、Nova 等） --- #### **4. 执行安装** ```bash packstack --answer-file=answer.txt ``` 安装完成后，会输出控制台 URL 和登录凭证。 --- #### **5. 验证安装** 访问 `http://<服务器IP>/dashboard`，使用 `admin` 和设置的密码登录 Horizon 控制台[^4]。 --- #### **注意事项** - **Python 兼容性**：CentOS 7 默认使用 Python 2.7，需手动安装 Python 3.6+ 并配置虚拟环境以支持新版本 OpenStack。 - **版本限制**：CentOS 7 上建议安装 *Train*（T 版）或 *Ussuri*（U 版），更高版本可能需 CentOS 8+。 ---
