CentOS 7 中 DevStack 如何安裝 OpenStack

1. 概述

OpenStack 是一個開源的云計算平臺，提供了虛擬機、存儲、網絡等基礎設施即服務（IaaS）功能。DevStack 是一個用于快速部署 OpenStack 開發環境的腳本工具，特別適合開發者和測試人員使用。本文將詳細介紹如何在 CentOS 7 系統中使用 DevStack 安裝 OpenStack。

2. 準備工作

在開始安裝之前，確保你的 CentOS 7 系統滿足以下要求：

• 至少 4GB 內存
• 至少 20GB 磁盤空間
• 穩定的網絡連接
• 已安裝 Git 和 Python 3

2.1 更新系統

首先，確保你的系統是最新的：

sudo yum update -y
sudo yum upgrade -y

2.2 安裝依賴包

安裝 DevStack 所需的依賴包：

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

2.3 創建用戶

為了安全起見，建議創建一個非 root 用戶來運行 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. 下載 DevStack

切換到 stack 用戶并下載 DevStack：

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

4. 配置 DevStack

4.1 創建 local.conf 文件

在 devstack 目錄下創建一個名為 local.conf 的配置文件，內容如下：

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