本文档提供了两个自动化脚本，分别用于部署OpenStack控制器节点和计算节点。脚本涵盖了主机名设置、基础配置、YUM源配置、FTP服务器配置、SSH免密登录、iaas-xiandian软件包配置、安装过程以及部署结果验证。通过这些步骤，实现了OpenStack环境的快速搭建和验证。

OpenStack脚本controlller端部署

## 当前用户名判定：
function UserJudgment() {
  read -p "当前的主机名为${HOSTNAME},是否修改(y/n):"
  echo -n "正在改名....."
  dop1=controller
  hostnamectl set-hostname ${dop1}
  bash
}

## 基础配置：
function BasicConfig() {
  systemctl disable --now firewalld
  setenforce 0
  echo "192.168.100.10 controller" >>/etc/hosts
  echo "192.168.100.20 compute" >>/etc/hosts
}

## 挂载镜像：
function MountImage() {
  mkdir -p /opt/centos /opt/iaas
  echo "/dev/cdrom              /opt/centos             iso9660 defaults        0 0" >>/etc/fstab
  echo "/opt/chinaskills_cloud_iaas.iso /opt/iaas       iso9660 defaults        0 0" >>/etc/fstab
  mount -a
}

## 配置YUM源：
function YUMConfig() {
  rm -rf /etc/yum.repos.d/*
  touch /etc/yum.repos.d/local.repo
  echo -e "[centos]\nname=centos\nbaseurl=file:///opt/centos\nenabled=1\ngpgcheck=0" >>/etc/yum.repos.d/local.repo

  yum makecache
}

## 配置FTP服务器
function FTPConfig() {
  yum -y install vsftpd
  echo "anon_root=/opt" >>/etc/vsftpd/vsftpd.conf
  systemctl start vsftpd && systemctl enable vsftpd
}

function SSHConfig() {
  yum install -y expect
  systemctl daemon-reload
  echo "StrictHostKeyChecking no" >>/etc/ssh/ssh_config
  expect -c "
spawn ssh-keygen
