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
bash
#!/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
setenforce 0
echo "SELinux disabled"
# 停用并禁用firewalld
systemctl stop firewalld
systemctl disable firewalld
echo "Firewalld stopped and disabled"
# 停用并禁用NetworkManager
systemctl stop NetworkManager
systemctl disable NetworkManager
echo "NetworkManager stopped and disabled"
echo "nameserver 8.8.8.8" >> /etc/resolv.conf
