1、openstack介绍

openstack是一个云平台管理的项目，它不是一个软件。也就是说我们可以使用openstack来管理我们一个数据中心大量资源池。它里面包含了很多子项目

openstack包含三大项:计算网络存储

openstack主要目标是来简化资源的管理和分配，把计算网络存储。三大项虚拟成三大资源池，例如需要计算资源我这里可以提供，需要网络资源这里也可以提供以及存储资源的需求，对外提供api，通过api进行交互

openstack架构

服务名称项目名称描述Dasgviard Horizon 基于Openstack API接口使用diango开发的Web管理 Compute Nova 通过虚拟化技术提供计算资源池 Networking Neutron 实现了虚拟机的网络资源管理。 Storage (存储) Object Storage Swift 对象存储，适用于“一次写入、多次读取” Block Storage Cinder 块存储，提供存储资源池 Share Services （共享服务） Identify Service Keystone 认证管理 Image Service Glance 提供虚拟镜像的注册和存储管理 Telemetry Ceilometer 提供监控和数据采集、计量服务 Higher-level Services (高层服务) Orchestration Heat 自动化部署的组件 Database Service Trove 提供数据库应用服务

Openstack服务介绍

MySQL：为各个服务提供数据存储

RabbitMq：为各个服务之间通信提供认证和服务注册

Keystone：为各个服务器之间通讯提供认证和服务注册

Glance：为虚拟机提供镜像管理

Nova：为虚拟机提供计算资源

Neutron：为虚拟机提供网络资源

2、部暑环境

2.1、主机信息

主机名	IP地址	角色	版本
controller	192.168.52.15(vm8) 172.16.2.15(vm1)	控制节点	Centos7
compute1	192.168.52.16(vm8) 172.16.2.16(vm1)	计算节点	Centos7
compute2	192.168.52.17(vm8) 172.16.2.17(vm1)	计算节点	Centos7

各角色描述及需求：

控制器：

①控制节点运行身份认证服务，镜像服务，管理部分计算和网络服务和不同的网络代理。同样包括像SQL数据库，消息队列这样的支撑服务。

②控制节点需要最少两块网卡。

计算：

①计算节点运行操作实例的 :hypervisor计算部分。默认情况下使用 KVM 作为hypervisor。计算节点同样运行网络服务代理，用来连接实例到虚拟网络，通过:security groups 为实例提供防火墙服务。

②这个服务可以部署超过1个计算节点。每个节点要求最少两个网络接口。

2.2、系统配置

1.添加hosts:

cat >> /etc/hosts << EOF

192.168.52.15 controller

192.168.52.16 compute1

192.168.52.17 compute2

EOF

2.关闭 selinux:

sed -i 's#SELINUX=enforcing#SELINUX=disabled#g' /etc/sysconfig/selinux

setenforce 0

3.关闭防火墙：

systemctl stop firewalld

systemctl disable firewalld

4.更改主机名:

hostnamectl set-hostname controller #控制节点

hostnamectl set-hostname compute1 #计算节点

hostnamectl set-hostname compute2 #计算节点

5.免密登录:

ssh-keygen -t rsa

ssh-copy-id controller

ssh-copy-id compute1

ssh-copy-id compute2

6.同步系统时间

yum install chrony -y

vim /etc/chrony.conf

server ntp.aliyun.com iburst

systemctl enable chronyd

systemctl restart chronyd

chronyc sources

7.修改网卡地址

①修改VM8网卡配置

vi /etc/sysconfig/network-scripts/ifcfg-ens33

BOOTPROTO=none

IPV4_ROUTE_METRIC=90 #调由优先级，NAT网卡优先

ONBOOT=yes

IPADDR=192.168.52.15

NETMASK=255.255.255.0

GATEWAY=192.168.52.2

②修改VM1网卡配置

vi /etc/sysconfig/network-scripts/ifcfg-ens37

BOOTPROTO=none

ONBOOT=yes

IPADDR=172.16.2.15

NETMASK=255.255.255.0

systemctl restart network #重启网卡

③配置DNS

vim /etc/resolv.conf

nameserver 114.114.114.114

nameserver 233.5.5.5

8.安装和openstack对应版本相关的仓库

yum -y install net-tools bash-completion vim gcc gcc-c++ make pcre pcre-devel expat-devel cmake bzip2

systemctl status mariadb

systemctl list-unit-files |grep mariadb

mysql_secure_installation #设置密码及初始化

Enter current password for root (enter for none): #回车

密码: abc123，一路 y 回车

systemctl restart mariadb

systemctl status mariadb

3.3、登陆mysql

mysql -uroot -p'abc123'

flush privileges;

show databases;

select user,host from mysql.user; #查看权限

4、安装配置消息队列服务rabbitmq（控制节点controller）

4.1、安装rabbitmq

yum install rabbitmq-server -y

systemctl enable rabbitmq-server

systemctl start rabbitmq-server

systemctl status rabbitmq-server

systemctl list-unit-files |grep rabbitmq-server

4.2、创建用户

mysql -ukeystone -pkeystone #测试keystone能否进行登录

7.2、安装、配置keystone

yum install httpd mod_wsgi -y

yum install openstack-keystone python-keystoneclient -y

遇见问题：在安装 openstack-keystone 和 python-keystoneclient 时，依赖包 python2-qpid-proton 需要 qpid-proton-c 的特定版本（0.26.0-2.el7），但系统中已经安装了更高版本的 qpid-proton-c（0.37.0-1.el7），导致依赖关系不满足。

解决方法：yum install qpid-proton-c-0.26.0-2.el7.x86_64 -y

openstack-config --set /etc/keystone/keystone.conf database connection mysql+pymysql://keystone:keystone@controller/keystone

openstack-config --set /etc/keystone/keystone.conf token provider fernet

# 查看生效的配置

egrep -v "^#|^$" /etc/keystone/keystone.conf

grep '^[a-z]' /etc/keystone/keystone.conf

#同步数据库
