OpenStack项目主要提供:计算服务、存储服务、镜像服务、网络服务,均依赖于身份认证keystone的支撑。其中的每个项目可以拆开部署,同一项目也可以部署在多台=物理机上,并且每个服务都提供了应用接口程序(API),方便与第三方集成调用资源。
环境准备
安装openstack环境的硬件需求
- CPU 支持intel 64或AMD 64 CPU扩展,并启用AMD-H或intel VT硬件虚拟化支持的64位x86处理器
- 内存 >=2G
- 磁盘空间 >=50G
虚拟机分配
主机名 | 操作系统 | IP地址 | 备注 |
---|---|---|---|
controller | CentOS-7.4-x86_64 | 172.16.10.33 | 控制节点 |
compute | CentOS-7.4-x86_64 | 172.16.10.35 | 计算节点 |
cinder | CentOS-7.4-x86_64 | 172.16.10.36 | 块存储节点 |
关闭虚拟机防火墙及selinux
systemctl disable firewalld.service
systemctl stop firewalld.service
vim /etc/sysconfig/selinux
SELINUX=disable //将enforcing修改为disable,永久关闭
setenforce 0
搭建OpenStack
环境准备
在接下来的操作中若无特别说明,则表示在三台主机上均进行相同操作
配置域名解析
修改所有主机名
hostnamectl set-hostname 主机名 //三台虚拟机修改相对应主机名,修改完成之后重启服务器
修改所有主机hosts文件
vim /etc/hosts
172.16.10.33 controller
172.16.10.35 compute
172.16.10.36 cinder //三台服务器hosts文件内容一致
测试各节点连通性
ping -c 4 openstack.org //是否ping通官网
ping -c 4 compute //各节点间测试
配置阿里云yum源
备份默认yum源
mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup
下载最新yum源
wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
安装配置NTP服务
在controller节点安装配置chrony
yum install chrony -y
vim /etc/chrony.conf
server controller iburst //所有节点向controller节点同步时间
allow 172.16.10.0/24 //设置时间同步网段
systemctl enable chronyd
systemctl restart chronyd
在compute节点安装配置chrony
yum install chrony -y
vim /etc/chrony.conf
server controller iburst
systemctl enable chronyd
systemctl restart chronyd
在cinder节点安装配置chrony
yum install chrony -y
vim /etc/chrony.conf
server controller iburst
systemctl enable chronyd
systemctl restart chronyd
验证时钟同步服务
chronyc sources
启用OpenStack库
yum install centos-release-openstack-queens -y

yum install openstack-selinux -y //安装openstack-selinux,便于自动管理openstack的安全策略
MySQL数据库部署(controller)
软件包安装
yum install mariadb mariadb-server python2-PyMySQL -y
配置文件修改
vim /etc/my.cnf.d/mariadb-server.cnf
[mysqld]
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
log-error=/var/log/mariadb/mariadb.log
pid-file=/var/run/mariadb/mariadb.pid
bind-address = 172.16.10.33 //修改为控制节点IP,使其他节点可以通过管理网络访问数据库
default-storage-engine = innodb
innodb_file_per_table = on
max_connections = 4096
collation-server = utf8_general_ci
character-set-server = utf8
启动服务并设置为开机自启
systemctl enable mariadb.service
systemctl start mariadb.service
对数据库进行安全加固
mysql_secure_installation
安装配置Messaging server-RabbitMQ
OpenStack使用message queue协调操作和各服务器的状态信息。消息队列服务一般运行在控制节点上。
在controller节点安装RabbitMQ
yum install rabbitmq-server -y
开启服务并设置为开机自启
systemctl enable rabbitmq-server.service
systemctl start rabbitmq-server.service
netstat -ntap | grep 5672
添加openstack用户
如果在添加用户时报错,就检查是否修改了主机名,或者是在之前的操作中修改主机名之后未重启,重启即可解决创建用户报错
rabbitmqctl add_user openstack 123456 //创建用户openstack,密码为123456
rabbitmqctl set_permissions openstack ".*" ".*" ".*" //授予新建用户权限
部署memcached服务(controller)
安装软件
yum install memcached python-memcached -y

etcd是一个分布式,一致的键值存储,用于共享配置和服务发现,特点是,安全,具有可选客户端证书身份验证的自动TLS;快速,基准测试10,000次/秒;可靠,使用Raft正确分发。
安装软件
yum install etcd -y
修改配置文件
vim /etc/etcd/etcd.conf

开启服务并设置为开机自启
systemctl enable etcd.service
systemctl start etcd.service
部署keystone认证服务
Identity服务为其他OpenStack服务提供验证和授权服务,为所有服务提供终端目录,其他OpenStack服务将身份认证当作通用统一API来使用。此外,提供用户信息但是不在OpenStack项目中的服务(如LDAP服务)可被整合进先前存在的基础设施中。
为了从identify服务中获益,其他的OpenStack服务需要与他合作。当某个OpenStack服务需要与他合作。当某个OpenStack服务收到来自用户的请求时,该服务询问identify服务,验证该用户是否有权限进行此次请求,身份验证服务包括以下组件
- 服务器:一个中心化的服务器使用RESTful接口来提供认证和授权服务
- 驱动:驱动或服务后端被整合进集中式服务器中。它们被用来访问OpenStack外部仓库的身份信息,并且它们可能已经存在于OpenStack被部署在的基础设施中,如SQL数据库
- 模块:中间件模块运行于使用身份验证服务的OpenStack组件的地址空间中。这些模块拦截服务请求,取出用户凭据,并将它们送入中央服务器寻求授权。中间件模块和OpenStack组件间的整合使用python web服务器网关接口。
当安装OpenStack自身服务时,用户必须将之注册到其OpenStack安装环境的每个服务。身份服务才可以追踪到哪些OpenStack服务已经安装,以及在网络中定位它们。
