OpenStack云平台搭建

OpenStack--开源的云计算管理平台项目

openstack

OpenStack是一个开源的云计算管理平台项目，是一系列软件开源项目的组合。由NASA(美国国家航空航天局)和Rackspace合作研发并发起，以Apache许可证（Apache软件基金会发布的一个自由软件许可证）授权。

OpenStack为私有云和公有云提供可扩展的弹性的云计算服务。项目目标是提供实施简单、可大规模扩展、丰富、标准统一的云计算管理平台。

OpenStack 简介

Openstack是一个云平台管理的项目，它不是一个软件。这个项目由几个主要的组件组合起来完成一些具体的工作。Openstack是一个旨在为公共及私有云的建设与管理提供软件的开源项目。它的社区拥有超过130家企业及1350位开发者，这些机构与个人将 Openstack作为基础设施即服务资源的通用前端。Openstack项目的首要任务是简化云的部署过程并为其带来良好的可扩展性。本文希望通过提供必要的指导信息，帮助大家利用 Openstack前端来设置及管理自己的公共云或私有云。

Openstack是由 Rackspace和NASA共同开发的云计算平台，帮助服务商和企业内部实现类似于 Amazon ec2和S3的云基础架构服务( Infrastructure as a Service)。Openstack包括两个主要模块:Nova和 Swift。前者是NASA开发的虚拟服务器部署和业务计算模块;后者是 Backpack开发的分布式云存储模块，两者可以一起用，也可以分开单独用。Openstack是开源项目，除了有 Rackspace和NASA的大力支持外，后面还有包括Dell、 Citrix、Cisco Canonical这些重量级公司的贡献和支持，发展速度非常快，有取代另一个业界领先开源云台 Eucalyptus的态势。

OpenStack 核心项目

OpenStack覆盖了网络、虚拟化、操作系统、服务器等各个方面。它是一个正在开发中的云计算平台项目，根据成熟及重要程度的不同，被分解成核心项目、孵化项目，以及支持项目和相关项目。每个项目都有自己的委员会和项目技术主管，而且每个项目都不是一成不变的，孵化项目可以根据发展的成熟度和重要性。 动漫女1
  1. 计算（Compute）：Nova，一套控制器，用于为单个用户或使用群组管理虚拟机实例的整个生命周期，根据用户需求来提供虚拟服务。负责虚拟机创建、开机、关机、挂起、暂停、调整、迁移、重启、销毁等操作，配置CPU、内存等信息规格，自Austin版本集成到项目中。
  2. 对象存储（Object Storage）：Swift，一套用于在大规模可扩展系统中通过内置冗余及高容错机制实现对象存储的系统，允许进行存储或者检索文件。可为Glance提供镜像存储，为Cinder提供卷备份服务，自Austin版本集成到项目中。
  3. 镜像服务（Image Service）：Glance，一套虚拟机镜像查找及检索系统，支持多种虚拟机镜像格式（AKI、AMI、ARI、ISO、QCOW2、Raw、VDI、VHD、VMDK），有创建上传镜像、删除镜像、编辑镜像基本信息的功能，自Bexar版本集成到项目中。

OpenStack云平台搭建说明

本次部署采用系统的是Centos 8-Stream版，存储库为OpenStack-Victoria版，除基础配置，五大服务中的时间同步服务，七大组件中的nova服务，neutron服务，cinder服务需要在双节点配置外，其他服务配置均在控制节点，neutron配置从公有网络和私有网络中选择一种即可，大多数情况还是选公有网络的配置，此次部署所有密码均为111111，可按自身需要自行配置 猫

安装环境

  • 采用虚拟化软件：VMware Workstation 16 Pro
  • 操作系统：Centos 8-Stream
  • 控制节点配置：内存4G，CPU4核，磁盘100G，启用虚拟化引擎
  • 计算节点配置：内存4G，CPU4核，磁盘100G，启用虚拟化引擎

基础配置(双节点)

Yum源仓库配置

           注意：以下配置yum是为了更快的更新源和下载安装包，但为了节省更多时间（1）和（2）都可跳过！！！！！

（1）阿里云镜像仓库地址：https://mirrors.aliyun.com

curl -o /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-vault-8.5.2111.repo

sed -i -e '/mirrors.cloud.aliyuncs.com/d' -e '/mirrors.aliyuncs.com/d' /etc/yum.repos.d/CentOS-Base.repo

（2）配置Centos 8的源只需改yum仓库.repo文件参数即可

                            注意！！！此方法可能会出现gpgcheck检查失败的问题，推荐(1)方法比较保险

# 同步nova_api数据库
[root@controller ~]# su -s /bin/sh -c "nova-manage api_db sync" nova

# 同步nova_cell0数据库
[root@controller ~]# su -s /bin/sh -c "nova-manage cell_v2 map_cell0" nova

# 创建cell1
[root@controller ~]# su -s /bin/sh -c "nova-manage cell_v2 create_cell --name=cell1 --verbose" nova

# 同步nova数据库
[root@controller ~]# su -s /bin/sh -c "nova-manage db sync" nova
(5) 创建nova用户和服务，关联admin角色
#创建nova用户
[root@controller ~]# openstack user create --domain default --password 111111 nova

#关联admin角色
[root@controller ~]# openstack role add --project service --user nova admin

#创建nova服务
[root@controller ~]# openstack service create --name nova --description "OpenStack Compute" compute
(6) 注册API接口
#public
[root@controller ~]# openstack endpoint create --region RegionOne compute public http://controller:8774/v2.1

#internal
[root@controller ~]# openstack endpoint create --region RegionOne compute internal http://controller:8774/v2.1

#admin
[root@controller ~]# openstack endpoint create --region RegionOne compute admin http://controller:8774/v2.1
(7) 查看服务端点
[root@controller ~]# openstack endpoint list
(8) 验证nova_cell0和cell1是否添加成功
[root@controller ~]# su -s /bin/sh -c "nova-manage cell_v2 list_cells" nova
(9) 启动nova所有服务并设为开机自启
[root@controller ~]# systemctl enable --now openstack-nova-api \
openstack-nova-scheduler openstack-nova-conductor openstack-nova-novncproxy
(10) 查看nova服务是否启动
[root@controller ~]# nova service-list

#一般只会显示两个服务：nova-scheduler和nova-conductor，这是因为上面这条命令是由nova-api接收，而它控制着nova-scheduler和nova-conductor服务，如果nova-api未开启，那这两个服务也会down掉，nova-novncproxy服务则是通过查看端口号的形式，示例如下：
[root@controller ~]# netstat -lntup | grep 6080
tcp        0      0 0.0.0.0:6080            0.0.0.0:*               LISTEN      1456/python3   
[root@controller ~]# ps -ef | grep 1456			
nova        1456       1  0 18:29 ?        00:00:05 /usr/bin/python3 /usr/bin/nova-novncproxy --web /usr/share/novnc/
root       27724   26054  0 20:51 pts/0    00:00:00 grep --color=auto 1456
(11) 如何通过web界面查看
#如果不配置域名解析，就直接用ip
http://10.10.10.10:6080

#如果要配置域名解析，在电脑C:\Windows\System32\drivers\etc目录下里面的hosts文件里添加
10.10.10.10		controller
10.10.10.20 	compute
#再访问
http://controller:6080

}

TIME_ZONE = "Asia/Shanghai"

(3) 配置http服务

[root@controller ~]# vi /etc/httpd/conf.d/openstack-dashboard.conf

WSGIApplicationGroup %{GLOBAL}			#添加这行

#编辑dashboard配置文件
[root@controller ~]# vim /etc/openstack-dashboard/local_settings 

WEBROOT = '/dashboard/'					#添加这行

(4) 重启http和缓存服务

[root@controller ~]# systemctl restart httpd.service memcached.service

(5) 登录web界面

#如果不配置域名解析，就直接用ip
http://10.10.10.10/dashboard

#如果要配置域名解析，在电脑C:\Windows\System32\drivers\etc目录下里面的hosts文件里添加
10.10.10.10		controller
10.10.10.20 	compute
#再访问
http://controller/dashboard

Cinder存储

控制节点

(1) 数据库创库授权
#进入数据库
[root@controller ~]# mysql -u root -p111111

#创建cinder数据库
MariaDB [(none)] CREATE DATABASE cinder;

#授权
MariaDB [(none)]> GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'localhost' IDENTIFIED BY '111111';
MariaDB [(none)]> GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'%' IDENTIFIED BY '111111';

(2) 安装cinder软件包

[root@controller ~]# dnf install -y openstack-cinder
(3) 编辑配置文件
#复制一份去掉注释
[root@controller ~]# cp /etc/cinder/cinder.conf /etc/cinder/cinder.conf.bak
[root@controller ~]# grep -Ev '^$|#' /etc/cinder/cinder.conf.bak > /etc/cinder/cinder.conf

#编辑
[root@controller ~]# vim /etc/cinder/cinder.conf
[DEFAULT]
transport_url = rabbit://openstack:111111@controller
auth_strategy = keystone
my_ip = 10.10.10.10

[database]
connection = mysql+pymysql://cinder:111111@controller/cinder

[keystone_authtoken]
www_authenticate_uri = http://controller:5000
auth_url = http://controller:5000
memcached_servers = controller:11211
auth_type = password
project_domain_name = default
user_domain_name = default
project_name = service
username = cinder
password = 111111

[oslo_concurrency]
lock_path = /var/lib/cinder/tmp
(4) 数据库初始化
[root@controller ~]# su -s /bin/sh -c "cinder-manage db sync" cinder
(5) 查看cinder数据库表信息
[root@controller ~]# mysql -uroot -p111111

MariaDB [(none)]> use cinder;
MariaDB [cinder]> show tables;
MariaDB [cinder]> quit
(6) 创建cinder用户和服务，关联admin角色
#创建cinder用户
[root@controller ~]# openstack user create --domain default --password 111111 cinder

#关联admin角色
[root@controller ~]# openstack role add --project service --user cinder admin

#创建cinderv2,cinderv3服务
[root@controller ~]# openstack service create --name cinderv2 --description "OpenStack Block Storage" volumev2
[root@controller ~]# openstack service create --name cinderv3 --description "OpenStack Block Storage" volumev3
(7) 注册API接口
cinderv2的服务端点
#public
[root@controller ~]# openstack endpoint create --region RegionOne volumev2 public http://controller:8776/v2/%\(project_id\)s

#internal
[root@controller ~]# openstack endpoint create --region RegionOne volumev2 internal http://controller:8776/v2/%\(project_id\)s

#admin
[root@controller ~]# openstack endpoint create --region RegionOne volumev2 admin http://controller:8776/v2/%\(project_id\)s
cinderv3的服务端点
#public
[root@controller ~]# openstack endpoint create --region RegionOne volumev3 public http://controller:8776/v3/%\(project_id\)s

#internal
[root@controller ~]# openstack endpoint create --region RegionOne volumev3 internal http://controller:8776/v3/%\(project_id\)s

#admin
[root@controller ~]# openstack endpoint create --region RegionOne volumev3 admin http://controller:8776/v3/%\(project_id\)s
(8) 查看服务端点
[root@controller ~]# openstack endpoint list
(9) 配置计算服务使用块存储
#编辑nova配置文件
[root@controller cinder]# vi /etc/nova/nova.conf
[cinder]
os_region_name = RegionOne

#重启nova
[root@controller ~]# systemctl restart openstack-nova-api.service
(10) 启动cinder服务并设置开机自启
[root@controller ~]# systemctl enable --now openstack-cinder-api.service openstack-cinder-scheduler.service

计算节点（关闭虚拟机添加一块硬盘，可自行选择大小，这里为50G）

(1) 查看磁盘
[root@compute ~]# fdisk --list
(2) 安装 LVM 包
[root@compute ~]# dnf -y install lvm2 device-mapper-persistent-data
(3) 创建 LVM 物理卷/dev/sdb
[root@compute ~]# pvcreate /dev/sdb
(4) 创建 LVM 卷组cinder-volumes
[root@compute ~]# vgcreate cinder-volumes /dev/sdb
(5) 修改LVM配置
#复制一份去掉注释
[root@compute ~]# cp /etc/lvm/lvm.conf /etc/lvm/lvm.conf.bak
[root@compute ~]# grep -Ev '^$|#' /etc/lvm/lvm.conf.bak > /etc/lvm/lvm.conf

#编辑
[root@compute ~]# vi /etc/lvm/lvm.conf
devices {
        filter = [ "a/sda/","a/sdb/","r/.*/"]
}
(6) 安装cinder相关软件包
[root@compute ~]# dnf install -y openstack-cinder targetcli python3-keystone
(7) 编辑cinder配置文件
#复制一份去掉注释
[root@compute ~]# cp /etc/cinder/cinder.conf /etc/cinder/cinder.conf.bak
[root@compute ~]# grep -Ev '^$|#' /etc/cinder/cinder.conf.bak > /etc/cinder/cinder.conf

#编辑
[root@compute ~]# vim /etc/cinder/cinder.conf
[DEFAULT]
transport_url = rabbit://openstack:111111@controller
auth_strategy = keystone
my_ip = 10.10.10.20
enabled_backends = lvm
glance_api_servers = http://controller:9292

[database]
connection = mysql+pymysql://cinder:111111@controller/cinder

[keystone_authtoken]
www_authenticate_uri = http://controller:5000
auth_url = http://controller:5000
memcached_servers = controller:11211
auth_type = password
project_domain_name = default
user_domain_name = default
project_name = service
username = cinder
password = 111111

[lvm]					#没有就添加
volume_driver = cinder.volume.drivers.lvm.LVMVolumeDriver
volume_group = cinder-volumes				#要与创建的卷组名对应
target_protocol = iscsi
target_helper = lioadm

[oslo_concurrency]
lock_path = /var/lib/cinder/tmp
(8) 启动cinder服务并设置开机自启
[root@compute ~]# systemctl enable --now openstack-cinder-volume.service target.service
(9) 返回控制节点，查看服务列表
[root@controller ~]# openstack volume service list
#显示这样就行
