要搭建OpenStack，可以使用Shell腳本來自動化部署過程。以下是一個簡單的Shell腳本示例，用于在Ubuntu上搭建OpenStack Newton版本。

```shell
#!/bin/bash

# 安裝必要的軟件包
sudo apt-get update
sudo apt-get install -y python-dev python-pip

# 安裝OpenStack CLI工具
sudo pip install python-openstackclient

# 安裝MySQL數據庫
sudo apt-get install -y mariadb-server python-pymysql
sudo sed -i 's/bind-address/#bind-address/' /etc/mysql/mariadb.conf.d/50-server.cnf
sudo systemctl restart mysql

# 創建OpenStack數據庫
sudo mysql -e "CREATE DATABASE keystone;"
sudo mysql -e "GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'localhost' IDENTIFIED BY 'password';"
sudo mysql -e "GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'%' IDENTIFIED BY 'password';"

# 安裝Keystone身份認證服務
sudo apt-get install -y keystone

# 配置Keystone
sudo cp /etc/keystone/keystone.conf /etc/keystone/keystone.conf.bak
sudo sed -i 's/connection = sqlite:\/\/\/\/var\/lib\/keystone\/keystone.db/connection = mysql+pymysql:\/\/keystone:password@localhost\/keystone/' /etc/keystone/keystone.conf
sudo sed -i 's/#admin_token = ADMIN/admin_token = TOKEN/' /etc/keystone/keystone.conf

# 初始化Keystone數據庫
sudo su -s /bin/sh -c "keystone-manage db_sync" keystone

# 啟動Keystone服務
sudo service keystone restart

# 創建admin和demo租戶
export OS_TOKEN=TOKEN
export OS_URL=http://localhost:35357/v3
openstack project create --domain default --description "Admin Project" admin
openstack project create --domain default --description "Demo Project" demo
openstack user create --domain default --password-prompt admin
openstack role create admin
openstack role add --project admin --user admin admin
openstack user create --domain default --password-prompt demo
openstack role create user
openstack role add --project demo --user demo user

# 驗證安裝
openstack --os-auth-url http://localhost:35357/v3 --os-project-domain-name default --os-user-domain-name default --os-project-name admin --os-username admin --os-password password token issue
```

注意：上述腳本僅用于演示目的，實際情況中可能需要進行更多的配置和調整。

要運行此腳本，可以將其保存為`openstack_setup.sh`文件，并在終端中運行以下命令：

```shell
chmod +x openstack_setup.sh
./openstack_setup.sh
```

腳本將自動完成安裝和配置OpenStack的過程。
