OpenStack-Train版-Allinone自动化部署脚本

一、环境准备

• 操作系统：CentOS 7 或以上版本

• 建议配置：

  • CPU：8 核或以上

  • 内存：16 GB 或以上

  • 磁盘：500 GB 或以上

• 网络配置：

  • 确保虚拟机已配置静态 IP 地址

  • 确保虚拟机可以正常访问外部网络

二、自动化部署脚本

#!/bin/bash

# 设置主机名
hostnamectl set-hostname openstack.alione.local
echo "Hostname set to openstack.alione.local"

# 修改/etc/hosts文件
echo "172.16.12.48 openstack openstack.alione.local" >> /etc/hosts
echo "/etc/hosts updated with the new hostname and IP address"

# 生成SSH密钥对
ssh-keygen -t rsa -b 2048 -f /root/.ssh/id_rsa -q -N ""
echo "SSH key pair generated"

# 将公钥复制到本机
ssh-copy-id -i /root/.ssh/id_rsa.pub [email protected]
echo "Public SSH key copied to [email protected]"

# 禁用SELinux
sed -i "s/SELINUX=enforcing/SELINUX=disabled/g" /etc/selinux/config
