镜像：https://mirrors.aliyun.com/centos-vault/7.2.1511/isos/x86_64/CentOS-7-x86_64-DVD-1511.iso?spm=a2c6h.25603864.0.0.5c565932JYniuU
openstack-mitaka rpm包：https://mirrors.aliyun.com/centos-vault/7.2.1511/cloud/x86_64/openstack-mitaka/?spm=a2c6h.25603864.0.0.c8773514w0jHOm
1.虚机安装
2.网络设置
3.虚机配置
3.1网卡名称设置
- 修改网卡名为
eth0和eth1，输入完成后按回车即可
net.ifnames=0 biosdevname=0
3.2基础设置
3.3网卡IP设置
3.4配置静态ip
vi /etc/sysconfig/network-scripts/ifcfg-eth0
eth0不需要上外网，所以不需要加网关和dns，否则会导致两张网卡冲突
BOOTPROTO=static
ONBOOT=yes
vi /etc/sysconfig/network-scripts/ifcfg-eth1
BOOTPROTO=static
ONBOOT=yes
IPADDR=192.168.200.10
GATEWAY=192.168.200.2
NETMASK=255.255.255.0
DNS1=114.114.114.114
ping www.baidu.com
64 bytes from 39.156.66.18: icmp_seq=l ttl=128 tim=251 ms
64 bytes from 39.156.66.18: icmp_seq=2 ttl=128 tim=205 ms
64 bytes from 39.156.66.18: icmp_seq=3 ttl=128 tim=42.8 ms
64 bytes from 39.156.66.18: icmp_seq=3 ttl=128 tim=42.9 ms
4.基于上述虚机克隆两台，一台作为计算节点compute，另一台作为存储节点block（只有一块网卡eth0，需要有两块磁盘）
4.1修改compute虚机的IP
eth0：192.168.100.20
eth1：192.68.200.20 # 可上外网
4.2修改block虚机的IP（不需要上外网）
eth0：192.168.100.30
NETMASK=255.255.255.0
- 删除
/etc/sysconfig/network-scripts/ifcfg-eth1
4.3修改三台虚机的主机名
hostnamectl set-hostname controller
hostnamectl set-hostname compute
hostnamectl set-hostname block
4.4虚机设置
- 关闭
NetworkManager服务（三台虚机都需要配置）
systemctl stop NetworkManager
systemctl disable NetworkManager
- 主机名绑定
/etc/hosts（三台虚机都需要配置）
192.168.100.10 controller
192.168.100.20 compute
192.168.100.30 block
- 验证三台虚机可以互相ping通，
ping controller、ping compute、ping block controller、compute可以ping通外网
- 关闭防火墙（三台虚机都需要配置）
systemctl stop firewalld
systemctl disable firewalld
- 关闭

- 2.启动httpd服务，并设置开机自启
systemctl enable httpd.service
systemctl start httpd.service
3.2.3.6在keystone上创建认证服务，并且注册API端点
- 1.创建
identity认证服务和注册api
# 1.设置环境变量（keystone配置）
export OS_TOKEN=ADMIN_TOKEN # 认证令牌
export OS_URL=http://controller:35357/v3 # 端点URL
export OS_IDENTITY_API_VERSION=3 # 认证 API 版本'''查看是否设置成功
[root@controller fernet-keys]# env | grep OS
OS_IDENTITY_API_VERSION=3
OS_TOKEN=ADMIN_TOKEN
OS_URL=http://controller:35357/v3

OpenStack使用三个API端点变种代表每种服务：admin，internal和public。默认情况下，管理API端点允许修改用户和租户而公共和内部APIs不允许这些操作。在生产环境中，处于安全原因，变种为了服务不同类型的用户可能驻留在单独的网络上。对实例而言，公共API网络为了让顾客管理他们自己的云在互联网上是可见的。管理API网络在管理云基础设施的组织中操作也是有所限制的。内部API网络可能会被限制在包含OpenStack服务的主机上。此外，OpenStack支持可伸缩性的多区域。为了简单起见，本指南为所有端点变种和默认
RegionOne区域都使用管理网络。
3.2.3.7在keystone上创建用户、项目、角色，以及关联关系

因为
环境变量中有一个超级管理员的token，所以可以使用openstack user list命令去查询当前用户列表
[root@controller ~]# env | grep OS_
OS_TOKEN=ADMIN_TOKEN[root@controller ~]# openstack user list

| ID | Name |
+----------------------------------+-------+
| 2049b7a000664a7c9dab8471e1b74fea | admin |

删除环境变量中的ADMIN_TOKEN，后则无法再次使用
openstack user list命令获取用户列表
[root@controller ~]# unset OS_TOKEN
[root@controller ~]# openstack user list
Missing parameter(s):
Set a username with --os-username, OS_USERNAME, or auth.username
Set an authentication URL, with --os-auth-url, OS_AUTH_URL or auth.auth_url
Set a scope, such as a project or domain, set a project scope with --os-project-name, OS_PROJECT_NAME or auth.project_name, set a domain scope with --os-domain-name, OS_DOMAIN_NAME or auth.domain_name
不使用环境变量的情况下，查询用户列表

推荐方式：使用脚本方式
# 1.创建 admin-openrc 文件，内容如下，如果直接使用环境变量，那么在退出终端后，环境变量就消失了，所以使用脚本保存
# vi /user/bin/admin-openrc # /user/bin默认添加到了系统环境变量中，所以将脚本放在此处，方便source

3.3.3.7启动镜像服务、并且配置开机自启
systemctl enable openstack-glance-api.service openstack-glance-registry.service
systemctl start openstack-glance-api.service openstack-glance-registry.service
[root@controller ~]# netstat -lntup

3.3.3.8测试镜像上传
- 1.下载测试镜像到contorller节点
# 下载失败的机率很大，建议浏览器或其他下载方式下载好之后，再上传上来
curl http://download.cirros-cloud.net/0.3.4/cirros-0.3.4-x86_64-disk.img -o cirros-0.3.4-x86_64-disk.img --progress
- 2.使用
openstack image create命令上传镜像
# --container-format bare 表示镜像是一个普通镜像，而不是docker镜像
# --public 表示是一个公共镜像
# --disk-format qcow2 镜像格式是qcow2
openstack image create "cirros" --file cirros-0.3.4-x86_64-disk.img \--disk-format qcow2 --container-format bare --public
此处镜像异常，只有273 bytes，后面基于这个镜像创建的虚机会有问题，找不到系统盘- 上传镜像时使用
qemu-img info 镜像名看一下镜像信息和上传的结果是否一致（此处是我下载镜像出了问题）

3.4Nova服务
3.4.1组件
- 只有nova-compute在
计算节点上 - 其他服务都在
控制节点上
3.4.1.1：nova-api 服务
- 接收并响应所有的计算服务请求，管理虚拟机生命周期
3.4.1.2：nova-compute 服务（可以有多个）
- 真正管理虚拟机（调用libvirt来管理虚机）
3.4.1.3：nova-scheduler 服务
- nova调度器（挑选出最适合的nova-compute来创建虚机）
3.4.1.4：nova-conductor 服务
- 代理nova-compute连接数据库（避免了所有nova-compute都配置数据库连接信息，不安全）
- 帮助nova-compute代理修改数据库中虚拟机的状态
3.4.1.5：nova-network 服务
- 早期openstack版本管理虚拟机的网络（已弃用，使用neutron服务组件替换）
3.4.1.6：nova-consoleauth 和 nova-novncproxy 服务
- web版的vnc来直接操做云主机
3.4.1.7：novncproxy 服务
- web版 vnc客户端
3.4.1.8：nova-api-metadata 服务
- 接收来自虚机发送的元数据请求
- 配合neutron-metadata-agent，来实现虚拟机的定制化操做
3.4.2安装（控制节点）
3.4.2.1创建数据库

- 停止
nova-api服务后就无法使用nova service-list来获取服务信息
systemctl stop openstack-nova-api.service
3.4.3安装（计算节点）
3.4.3.1安装说明
- 计算节点只需要安装
nova-compute这一个组件 nova-compute通过调用libvirt来创建虚拟机
3.4.3.2安装
yum install openstack-nova-compute -y
yum install openstack-utils.noarch -y
3.4.3.3修改配置文件
- 1.备份
/etc/nova/nova.conf文件，并去掉注释

3.4.3.4确定您的计算节点是否支持虚拟机的硬件加速。
egrep -c '(vmx|svm)' /proc/cpuinfo
[root@compute ~]# egrep -c '(vmx|svm)' /proc/cpuinfo
4
务必注意：如果这个命令返回了 zero 值，那么你的计算节点不支持硬件加速。你必须配置 libvirt 来使用 QEMU 去代替 KVM
openstack-config --set /etc/nova/nova.conf libvirt virt_type qemu
3.4.3.5启动nova-compute服务，并设置开机自启
systemctl enable libvirtd.service openstack-nova-compute.service
systemctl start libvirtd.service openstack-nova-compute.service

3.7Cinder服务
3.7.1工作原理
- cinder是openstack的块存储服务，为云主机分配硬盘。使用LVM划分LV，然后使用iSCSI共享给计算节点的KVM
3.7.2组件
3.7.2.1.cinder-api
- 接受API请求，并将其路由到
cinder-volume执行。 运行在控制节点
3.7.2.2.cinder-volume（可以有多个）
- 与块存储服务和例如
cinder-scheduler的进程进行直接交互。它也可以与这些进程通过一个消息队列进行交互。cinder-volume服务响应送到块存储服务的读写请求来维持状态。它也可以和多种存储提供者在驱动架构下进行交互。 - 调用
LVM、nfs、gfs、ceph然后支持多种存储技术
3.7.2.3.cinder-scheduler守护进程
- 选择最优存储提供节点来创建卷。其与
nova-scheduler组件类似。 运行在控制节点
3.7.2.4.cinder-backup守护进程
- 提供任何种类备份卷到一个备份存储提供者。就像
cinder-volume服务，它与多种存储提供者在驱动架构下进行交互。
3.7.2.5.消息队列
- 在块存储的进程之间路由信息。
3.7.3安装（控制节点）
3.7.3.1创建数据库
- 1.创建数据库
mysql -u root -popenstack
CREATE DATABASE cinder;
MariaDB [(none)]> show databases;
+--------------------+

- 3.修改
控制节点的计算服务nova配置
openstack-config --set /etc/nova/nova.conf cinder os_region_name RegionOne
3.7.3.6数据库迁移
su -s /bin/sh -c "cinder-manage db sync" cinder
3.7.3.7重启控制节点计算服务API
systemctl restart openstack-nova-api.service
3.7.3.8启动存储服务，并设置开机自启
systemctl enable openstack-cinder-api.service openstack-cinder-scheduler.service
systemctl start openstack-cinder-api.service openstack-cinder-scheduler.service
3.7.3.9验证
[root@controller ~]# cinder service-list
+------------------+------------+------+---------+-------+------------+-----------------+
| Binary | Host | Zone | Status | State | Updated_at | Disabled Reason |
+------------------+------------+------+---------+-------+------------+-----------------+
| cinder-scheduler | controller | nova | enabled | up | - | - |
+------------------+------------+------+---------+-------+------------+-----------------+
3.7.4安装（存储节点）
- 说明：如果只有两台服务器，则可以将以下服务安装在计算或控制节点
3.7.4.1安装chrony时间同步服务
- 1.安装（三台服务器都需要）
yum install -y chrony
- 2.配置
vi /etc/chrony.conf（控制节点）
#server 0.centos.pool.ntp.org iburst
#server 1.centos.pool.ntp.org iburst
#server 2.centos.pool.ntp.org iburst
#server 3.centos.pool.ntp.org iburst
server controller iburst # 增加
- 3.执行同步命令
chronyc sources
- 5.重启chrony服务（三台服务器都需要）
systemctl restart chronyd
3.7.4.1存储节点临时上网
3.7.4.1.1VMnet1网卡配置
3.7.4.1.2添加临时网关
- 1.添加临时网关
ip route add default via 192.168.100.1
- 2.验证
[root@block ~]# ping www.baidu.com
PING www.a.shifen.com (39.156.66.14) 56(84) bytes of data.
64 bytes from 39.156.66.14: icmp_seq=1 ttl=128 time=100 ms
64 bytes from 39.156.66.14: icmp_seq=2 ttl=128 time=54.7 ms
64 bytes from 39.156.66.14: icmp_seq=3 ttl=128 time=143 ms
- 3.删除临时网关
ip route del default via 192.168.100.1
- 4.验证
[root@block ~]# ping www.baidu.com
connect: Network is unreachable
3.7.4.2拷贝控制节点openstack-mitaka.repoyum源
scp root@controller:/etc/yum.repos.d/openstack-mitaka.repo /etc/yum.repos.d/
3.7.4.3安装lvm2
yum install lvm2 -y
3.7.4.5启动LVM的metadata服务并且设置该服务随系统启动：
systemctl enable lvm2-lvmetad.service
systemctl start lvm2-lvmetad.service
systemctl enable lvm2-lvmetad.service如果有如下报错
The unit files have no [Install] section. They are not meant to be enabled
using systemctl.
Possible reasons for having this kind of units are:
1) A unit may be statically enabled by being symlinked from another unit's.wants/ or .requires/ directory.
2) A unit's purpose may be to act as a helper for some other unit which hasa requirement dependency on it.
3) A unit may be started when needed via activation (socket, path, timer,D-Bus, udev, scripted systemctl call, ...).
- 1.给
/usr/lib/systemd/system/lvm2-lvmetad.service增加写权限
chmod 644 /usr/lib/systemd/system/lvm2-lvmetad.service
- 2.给
/usr/lib/systemd/system/lvm2-lvmetad.service增加以下内容
[Install]
WantedBy=multi-user.target
- 3.再次执行开机自启命令
[root@block system]# systemctl enable lvm2-lvmetad.service
Created symlink from /etc/systemd/system/multi-user.target.wants/lvm2-lvmetad.service to /usr/lib/systemd/system/lvm2-lvmetad.service.
3.7.4.6创建LVM
3.7.4.6.1划分物理卷 /dev/sdb
fdisk -l确认存储节点上另一块盘名称是/dev/sdb，否则根据实际名称操做
pvcreate /dev/sdb
# Physical volume "/dev/sdb" successfully created
[root@block ~]# pvsPV VG Fmt Attr PSize PFree /dev/sdb lvm2 --- 50.00g 50.00g
3.7.4.6.2使用 /dev/sdb 物理卷创建卷组
- 此处创建的卷组
cinder-volumes在后续的配置文件中会使用到，根据自己需要命名 - 卷组的创建也可以使用
多个物理卷来组成一个超大的卷组
vgcreate cinder-volumes /dev/sdb
# Volume group "cinder-volumes" successfully created
[root@block ~]# vgsVG #PV #LV #SN Attr VSize VFree cinder-volumes 1 0 0 wz--n- <50.00g <50.00g
3.7.4.7配置卷组的访问控制权限
vi /etc/lvm/lvm.conf
# 因为存储节点这台虚拟机操作系统磁盘也使用了LVM，所以需要将系统盘也添加进来
# 一定不要忘记结尾的/
filter = [ "a/sda/", "a/sdb/", "r/.*/"]
- a：access（允许）
- r：reject（拒绝）
3.7.4.8安装cinder相关组件
3.7.4.8.1安装
yum install openstack-cinder targetcli python-keystone -y
3.7.4.8.2配置
- 1.备份
/etc/cinder/cinder.conf文件，并去掉注释
cp /etc/cinder/cinder.conf /etc/cinder/cinder.conf.bak
grep -Ev '^$|#' /etc/cinder/cinder.conf.bak > /etc/cinder/cinder.conf
- 2.使用
openstack-config命令修改相关配置
openstack-config --set /etc/cinder/cinder.conf database connection mysql+pymysql://cinder:CINDER_DBPASS@controller/cinderopenstack-config --set /etc/cinder/cinder.conf DEFAULT rpc_backend rabbitopenstack-config --set /etc/cinder/cinder.conf oslo_messaging_rabbit rabbit_host controller

# cinder-volumes：是前面创建的卷组名
openstack-config --set /etc/cinder/cinder.conf lvm volume_group cinder-volumes
openstack-config --set /etc/cinder/cinder.conf lvm iscsi_protocol iscsi

如果有多块物理卷可以使用以下方式做区分（此处没有，略过）
openstack-config --set /etc/cinder/cinder.conf DEFAULT enabled_backends ssd,sataopenstack-config --set /etc/cinder/cinder.conf lvm volume_driver cinder.volume.drivers.lvm.LVMVolumeDriver
openstack-config --set /etc/cinder/cinder.conf lvm volume_group cinder-volumes
openstack-config --set /etc/cinder/cinder.conf lvm iscsi_protocol iscsi
openstack-config --set /etc/cinder/cinder.conf lvm iscsi_helper lioadm
volume_backend_name = sataopenstack-config --set /etc/cinder/cinder.conf lvm volume_driver cinder.volume.drivers.lvm.LVMVolumeDriver
openstack-config --set /etc/cinder/cinder.conf lvm volume_group cinder-volumes
openstack-config --set /etc/cinder/cinder.conf lvm iscsi_protocol iscsi
openstack-config --set /etc/cinder/cinder.conf lvm iscsi_helper lioadm
volume_backend_name = ssd
3.7.4.9启动cinder相关服务，并设置开机自启
systemctl enable openstack-cinder-volume.service target.service
systemctl start openstack-cinder-volume.service target.service
