CentOS 7 中 DevStack 如何安装 OpenStack

1. 概述

OpenStack 是一个开源的云计算平台，提供了虚拟机、存储、网络等基础设施即服务（IaaS）功能。DevStack 是一个用于快速部署 OpenStack 开发环境的脚本工具，特别适合开发者和测试人员使用。本文将详细介绍如何在 CentOS 7 系统中使用 DevStack 安装 OpenStack。

2. 准备工作

在开始安装之前，确保你的 CentOS 7 系统满足以下要求：

• 至少 4GB 内存
• 至少 20GB 磁盘空间
• 稳定的网络连接
• 已安装 Git 和 Python 3

2.1 更新系统

首先，确保你的系统是最新的：

sudo yum update -y
sudo yum upgrade -y

2.2 安装依赖包

安装 DevStack 所需的依赖包：

sudo yum install -y git python3 python3-devel libffi-devel gcc openssl-devel

2.3 创建用户

为了安全起见，建议创建一个非 root 用户来运行 DevStack：

sudo useradd -s /bin/bash -d /opt/stack -m stack
echo "stack ALL=(ALL) NOPASSWD: ALL" | sudo tee /etc/sudoers.d/stack
sudo su - stack

3. 下载 DevStack

切换到 stack 用户并下载 DevStack：

git clone https://opendev.org/openstack/devstack
cd devstack

4. 配置 DevStack

4.1 创建 local.conf 文件

在 devstack 目录下创建一个名为 local.conf 的配置文件，内容如下：

”`ini [[local|localrc]] ADMIN_PASSWORD=secret DATABASE_PASSWORD=\(ADMIN_PASSWORD RABBIT_PASSWORD=\)ADMIN_PASSWORD SERVICE_PASSWORD=$ADMIN_PASSWORD
