openstack中设置环境变量，export os_url=http://controller:35357/v3命设置完成后如确认环境变量OS_URL被正确设置

您可以在终端中输入以下命令来确认环境变量OS_URL被正确设置：

echo $OS_URL

如果输出结果为：

http://controller:35357/v3

那么环境变量已经被正确设置。

脚本部署Openstack 某企业拟使用OpenStack搭建一个企业云平台，以实现资源池化弹性管理、企业应用集中管理、统一安全认证和授权等管理。 规划： 云服务器1 主机名Controller: 接口eth33IP地址192.168.100.10/24,仅主机模式 接口eth34IP地址保持默认,NAT模式 云服务器2 主机名Compute 接口eth33IP地址192.168.100.20/24,仅主机模式 接口eth34IP地址保持默认,NAT模式 本实验使用到三个网段： 192.168.100.0/24，Openstack管理网络，Vmware仅主机模式 192.168.200.0/24，Openstack数据网络，云主机外部网络，VmwareNAT模式 10.0.0.0/24，云主机内部网络 使用两台主机部署出Openstack平台，要求云平台能够正常创建出云主机并正常通信。

以下是一个简单的脚本部署 OpenStack 的示例，您可以根据自己的实际情况进行修改和调整。本脚本适用于 CentOS 7 系统。

openstack T版本环境搭建的脚本

搭建 OpenStack T 版本环境需要进行多个步骤，包括环境准备、安装依赖包、配置数据库和消息队列、安装和配置各个组件等。这里提供一个参考脚本，供你参考：

#!/bin/bash

# 环境准备
echo "nameserver 8.8.8.8" > /etc/resolv.conf
echo "nameserver 8.8.4.4" >> /etc/resolv.conf
hostnamectl set-hostname controller

# 安装依赖包
yum install -y centos-release-openstack-train
yum update -y
yum install -y python-openstackclient
yum install -y openstack-selinux

# 配置数据库和消息队列
yum install -y mariadb mariadb-server python2-PyMySQL
systemctl enable mariadb.service
systemctl start mariadb.service
mysql_secure_installation
echo "[mysqld]

innodb_locks_unsafe_for_binlog=1
query_cache_size=0
query_cache_type=0
bind-address = 10.0.0.11

[mysql]
bind-address = 10.0.0.11" > /etc/my.cnf.d/openstack.cnf

yum install -y rabbitmq-server
systemctl enable rabbitmq-server.service
systemctl start rabbitmq-server.service
rabbitmqctl add_user openstack RABBIT_PASS
rabbitmqctl set_permissions openstack ".*" ".*" ".*"

# 安装和配置各个组件
yum install -y openstack-keystone httpd mod_wsgi

# 配置 Keystone
openstack-config --set /etc/keystone/keystone.conf database connection mysql+pymysql://keystone:KEYSTONE_DBPASS@controller/keystone
openstack-config --set /etc/keystone/keystone.conf token provider fernet
su -s /bin/sh -c "keystone-manage db_sync" keystone

  --bootstrap-internal-url http://controller:5000/v3/ \
  --bootstrap-public-url http://controller:5000/v3/ \
  --bootstrap-region-id RegionOne

# 配置 Apache
echo "ServerName controller" > /etc/httpd/conf.d/servername.conf
