随着云计算技术的不断发展,OpenStack作为一种开源的云计算管理平台,已经成为了企业级私有云的首选解决方案,本文将详细介绍如何在VPS上搭建OpenStack,帮助读者快速掌握OpenStack的部署与使用。

OpenStack简介

OpenStack是一个由多个开源项目组成的云计算管理平台,旨在帮助组织构建和管理私有云和公有云,OpenStack提供了广泛的API接口,支持多种虚拟化技术,如KVM、Xen、VMware等,其主要组件包括Nova(计算服务)、Neutron(网络服务)、Cinder(存储服务)、Keystone(身份认证服务)等。

VPS搭建OpenStack的准备工作

1、准备一台VPS服务器,建议选择配置较高的服务器,以便更好地支持OpenStack的运行。

2、安装操作系统,推荐使用Ubuntu 18.04 LTS或CentOS 7。

3、配置网络,确保VPS服务器可以访问互联网。

4、安装必要的依赖包,如python3-pip、git等。

OpenStack搭建步骤

1、安装OpenStack包管理器

在Ubuntu 18.04 LTS上,执行以下命令安装OpenStack包管理器:

sudo apt update
sudo apt install software-properties-common
sudo add-apt-repository cloud-archive:train
sudo apt update
sudo apt install python3-openstackclient

在CentOS 7上,执行以下命令安装OpenStack包管理器:

sudo yum install centos-release-openstack-train
sudo yum install python3-openstackclient

2、安装OpenStack组件

在Ubuntu 18.04 LTS上,执行以下命令安装OpenStack组件:

sudo apt install openstack-dashboard
sudo apt install nova-api nova-conductor nova-consoleauth nova-novncproxy nova-scheduler
sudo apt install neutron-server neutron-plugin-ml2 neutron-linuxbridge-agent neutron-dhcp-agent neutron-l3-agent neutron-metadata-agent
sudo apt install cinder-api cinder-scheduler cinder-volume
sudo apt install keystone

在CentOS 7上,执行以下命令安装OpenStack组件:

sudo yum install openstack-dashboard
sudo yum install openstack-nova-api openstack-nova-conductor openstack-nova-consoleauth openstack-nova-novncproxy openstack-nova-scheduler
sudo yum install openstack-neutron openstack-neutron-ml2 openstack-neutron-linuxbridge openstack-neutron-dhcp openstack-neutron-l3 openstack-neutron-metadata
sudo yum install openstack-cinder-api openstack-cinder-scheduler openstack-cinder-volume
sudo yum install openstack-keystone

3、配置OpenStack组件

(1)配置Keystone

编辑/etc/keystone/keystone.conf 文件,设置以下参数:

[database]
connection = mysql+pymysql://keystone:KEystoneDBPassword@localhost/keystone
[token]
provider = fernet
[Catalog]
driver = keystone.catalog.backends.sql.Catalog

创建Keystone数据库:

sudo mysql -u root -p
CREATE DATABASE keystone;
GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'localhost' IDENTIFIED BY 'KEystoneDBPassword';
GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'%' IDENTIFIED BY 'KEystoneDBPassword';
FLUSH PRIVILEGES;
EXIT;

同步Keystone数据库:

sudo su -s /bin/sh -c "keystone-manage db_sync" keystone

启动Keystone服务:

sudo systemctl start openstack-keystone
sudo systemctl enable openstack-keystone

创建Keystone认证令牌:

openstack token issue -f value -c id

(2)配置Nova

编辑/etc/nova/nova.conf 文件,设置以下参数:

[api]
auth_strategy = keystone
[keystone_authtoken]
auth_url = http://controller:5000/v3
memcached_servers = controller:11211
auth_type = password
project_domain_name = default
user_domain_name = default
project_name = service
username = nova
password = NovaPassword
[database]
connection = mysql+pymysql://nova:NovaDBPassword@localhost/nova_api

创建Nova数据库:

sudo mysql -u root -p
CREATE DATABASE nova_api;
GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'localhost' IDENTIFIED BY 'NovaDBPassword';
GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'%' IDENTIFIED BY 'NovaDBPassword';
FLUSH PRIVILEGES;
EXIT;

同步Nova数据库:

sudo su -s /bin/sh -c "nova-manage api_db sync" nova

启动Nova服务:

sudo systemctl start openstack-nova-api
sudo systemctl start openstack-nova-consoleauth
sudo systemctl start openstack-nova-scheduler
sudo systemctl start openstack-nova-conductor
sudo systemctl enable openstack-nova-api
sudo systemctl enable openstack-nova-consoleauth
sudo systemctl enable openstack-nova-scheduler
sudo systemctl enable openstack-nova-conductor

(3)配置Neutron

编辑/etc/neutron/neutron.conf 文件,设置以下参数:

[database]
connection = mysql+pymysql://neutron:NeutronDBPassword@localhost/neutron
[keystone_authtoken]
auth_url = http://controller:5000/v3
memcached_servers = controller:11211
auth_type = password
project_domain_name = default
user_domain_name = default
project_name = service
username = neutron
password = NeutronPassword
[service_providers]
service_types = neutron

创建Neutron数据库:

sudo mysql -u root -p
CREATE DATABASE neutron;
GRANT ALL PRIVILEGES ON neutron.* TO 'neutron'@'localhost' IDENTIFIED BY 'NeutronDBPassword';
GRANT ALL PRIVILEGES ON neutron.* TO 'neutron'@'%' IDENTIFIED BY 'NeutronDBPassword';
FLUSH PRIVILEGES;
EXIT;

同步Neutron数据库:

sudo su -s /bin/sh -c "neutron-db-manage --subproject neutron --config-file /etc/neutron/neutron.conf upgrade head" neutron

启动Neutron服务:

sudo systemctl start openstack-neutron
sudo systemctl enable openstack-neutron

(4)配置Cinder

编辑/etc/cinder/cinder.conf 文件,设置以下参数:

[database]
connection = mysql+pymysql://cinder:CinderDBPassword@localhost/cinder
[keystone_authtoken]
auth_url = http://controller:5000/v3
memcached_servers = controller:11211
auth_type = password
project_domain_name = default
user_domain_name = default
project_name = service
username = cinder
password = CinderPassword

创建Cinder数据库:

sudo mysql -u root -p
CREATE DATABASE cinder;
GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'localhost' IDENTIFIED BY 'CinderDBPassword';
GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'%' IDENTIFIED BY 'CinderDBPassword';
FLUSH PRIVILEGES;
EXIT;

同步Cinder数据库:

sudo su -s /bin/sh -c "cinder-manage db sync" cinder

启动Cinder服务:

sudo systemctl start openstack-cinder-api
sudo systemctl start openstack-cinder-scheduler
sudo systemctl start openstack-cinder-volume
sudo systemctl enable openstack-cinder-api
sudo systemctl enable openstack-cinder-scheduler
sudo systemctl enable openstack-cinder-volume

4、配置OpenStack网络

(1)创建外部网络

openstack network create --external --provider physicsnet external_network
openstack subnet create --network external_network --allocation-pool start=192.168.1.100,end=192.168.1.200 --dns-nameserver 8.8.8.8 --gateway 192.168.1.1 external_subnet

(2)创建内部网络

openstack network create internal_network
openstack subnet create --network internal_network --allocation-pool start=10.0.0.100,end=10.0.0.200 --dns-nameserver 8.8.8.8 --gateway 10.0.0.1 internal_subnet

(3)创建路由器

openstack router create router1
openstack router add subnet router1 internal_subnet
openstack router set --external-gateway external_network router1

5、使用OpenStack

(1)登录OpenStack Dashboard

在浏览器中输入http://controller:8000,使用管理员账号登录OpenStack Dashboard。

(2)创建虚拟机

在OpenStack Dashboard中,创建虚拟机,选择内部网络和外部网络。

(3)访问虚拟机

通过OpenStack Dashboard的浮动IP地址访问虚拟机。
