随着云计算技术的迅猛发展,越来越多的企业和个人开始关注和使用云服务,OpenStack作为开源的云计算管理平台,因其灵活性和可扩展性,受到了广泛的关注和应用,本文将详细介绍如何在VPS(虚拟专用服务器)上搭建OpenStack私有云平台,帮助读者从零开始掌握这一技术。

准备工作

1、选择合适的VPS

硬件要求:至少4核CPU、8GB内存、100GB硬盘空间。

操作系统:推荐使用Ubuntu 20.04 LTS或CentOS 8。

2、安装必要的工具

SSH客户端:用于远程连接VPS。

文本编辑器:如Vim或Nano。

3、更新系统

```bash

sudo apt update && sudo apt upgrade -y

```

安装OpenStack基础环境

1、安装OpenStack包管理工具

Ubuntu

```bash

sudo apt install software-properties-common

sudo add-apt-rePOSitory cloud-archive:ussuri

sudo apt update && sudo apt install python3-openstackclient -y

```

CentOS

```bash

sudo yum install centos-release-openstack-ussuri -y

sudo yum install python3-openstackclient -y

```

2、配置网络

设置主机名

```bash

sudo hostnamectl set-hostname openstack-controller

```

编辑主机文件

```bash

sudo nano /etc/hosts

```

添加以下内容:

```

127.0.0.1 localhost

127.0.1.1 openstack-controller

```

3、安装数据库

安装MariaDB

```bash

sudo apt install mariadb-server python3-pymysql -y

```

配置MariaDB

```bash

sudo mysql_secure_installation

```

按提示设置root密码并优化配置。

4、安装消息队列服务

安装RabbitMQ

```bash

sudo apt install rabbitmq-server -y

```

设置RabbitMQ用户

```bash

sudo rabbitmqctl add_user openstack openstack

sudo rabbitmqctl set_perMissions openstack ".*" ".*" ".*"

```

5、安装Memcached

```bash

sudo apt install memcached python3-memcache -y

```

6、安装Etcd

```bash

sudo apt install etcd -y

```

安装OpenStack服务

1、安装Keystone(身份认证服务)

安装软件包

```bash

sudo apt install keystone apache2 libapache2-mod-wsgi-py3 -y

```

配置数据库

```bash

sudo mysql -u root -p

CREATE DATABASE keystone;

GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'localhost' IDENTIFIED BY 'keystone';

GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'%' IDENTIFIED BY 'keystone';

EXIT;

```

配置Keystone

编辑/etc/keystone/keystone.conf,添加数据库连接信息:

```ini

[database]

connection = mysql+pymysql://keystone:keystone@localhost/keystone

```

初始化数据库

```bash

sudo keystone-manage db_sync

```

配置Apache

编辑/etc/apache2/sites-available/wsgi-keystone.conf,添加以下内容:

```apache

<VirtualHost *:5000>

ServerName openstack-controller

WSGIDaemonProcess keystone-public processes=1 threads=1 user=keystone group=keystone display-name=%{GROUP}

WSGIScriptAlias / /usr/bin/keystone-wsgi-public

WSGIProcessGroup keystone-public

WSGIApplicationGroup %{GLOBAL}

WSGISocketPrefix /var/run/keystone

LogLevel info

ErrorLogFormat "%{cu}t %M"

ErrorLog /var/log/apache2/keystone.log

CustomLog /var/log/apache2/keystone_access.log combined

</VirtualHost>

```

重启Apache

```bash

sudo systemctl restart apache2

```

2、安装Glance(镜像服务)

安装软件包

```bash

sudo apt install glance -y

```

配置数据库

```bash

sudo mysql -u root -p

CREATE DATABASE glance;

GRANT ALL PRIVILEGES ON glance.* TO 'glance'@'localhost' IDENTIFIED BY 'glance';

GRANT ALL PRIVILEGES ON glance.* TO 'glance'@'%' IDENTIFIED BY 'glance';

EXIT;

```

配置Glance

编辑/etc/glance/glance-api.conf/etc/glance/glance-registry.conf,添加数据库连接信息:

```ini

[database]

connection = mysql+pymysql://glance:glance@localhost/glance

```

初始化数据库

```bash

sudo glance-manage db_sync

```

3、安装Nova(计算服务)

安装软件包

```bash

sudo apt install nova-api nova-conductor nova-consoleauth nova-novncproxy nova-scheduler -y

```

配置数据库

```bash

sudo mysql -u root -p

CREATE DATABASE nova_api;

CREATE DATABASE nova;

GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'localhost' IDENTIFIED BY 'nova';

GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'%' IDENTIFIED BY 'nova';

GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'localhost' IDENTIFIED BY 'nova';

GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'%' IDENTIFIED BY 'nova';

EXIT;

```

配置Nova

编辑/etc/nova/nova.conf,添加数据库连接信息:

```ini

[database]

connection = mysql+pymysql://nova:nova@localhost/nova

```

4、安装Neutron(网络服务)

安装软件包

```bash

sudo apt install neutron-server neutron-plugin-ml2 neutron-linuxbridge-agent neutron-dhcp-agent neutron-metadata-agent -y

```

配置数据库

```bash

sudo mysql -u root -p

CREATE DATABASE neutron;

GRANT ALL PRIVILEGES ON neutron.* TO 'neutron'@'localhost' IDENTIFIED BY 'neutron';

GRANT ALL PRIVILEGES ON neutron.* TO 'neutron'@'%' IDENTIFIED BY 'neutron';

EXIT;

```

配置Neutron

编辑/etc/neutron/neutron.conf,添加数据库连接信息:

```ini

[database]

connection = mysql+pymysql://neutron:neutron@localhost/neutron

```

5、安装Horizon(仪表盘服务)

安装软件包

```bash

sudo apt install openstack-dashboard -y

```

配置和测试

1、配置Keystone认证

创建服务实体和端点

```bash

openstack service create --name keystone --description "OpenStack Identity" identity

openstack endpoint create --region RegionOne identity public http://openstack-controller:5000/v3

openstack endpoint create --region RegionOne identity internal http://openstack-controller:5000/v3

openstack endpoint create --region RegionOne identity admin http://openstack-controller:5000/v3

```

2、创建项目和用户

创建admin项目和用户

```bash

openstack project create --domain default --description "Admin Project" admin

openstack user create --domain default --project admin --password-prompt admin

openstack role create admin

openstack role add --project admin --user admin admin

```

3、测试环境

获取认证令牌

```bash

openstack token issue

```

通过以上步骤,我们成功在VPS上搭建了OpenStack私有云平台,虽然过程较为复杂,但掌握了这些基本操作后,可以进一步扩展和优化云平台,满足更多业务需求,希望本文能为读者提供有价值的参考。
