（一）云計算的服務型別
IAAS：基礎設施即服務，如：云主機
PAAS:平臺即服務，如：docker
SAAS:軟體即服務，如：購買企業郵箱，CDN
| 傳統IT | IAAS | PAAS | SAAS |
|---|---|---|---|
| 1應用 | 你管理 | 你管理 | 服務上管理 |
| 2資料 | 你管理 | 你管理 | 服務上管理 |
| 3運行時 | 你管理 | 服務上管理 | 服務上管理 |
| 4中間件 | 你管理 | 服務上管理 | 服務上管理 |
| 5作業系統 | 服務上管理 | 服務上管理 | 服務上管理 |
| 6虛擬化 | 服務上管理 | 服務上管理 | 服務上管理 |
| 7服務器 | 服務上管理 | 服務上管理 | 服務上管理 |
| 8存盤 | 服務上管理 | 服務上管理 | 服務上管理 |
| 9網路 | 服務上管理 | 服務上管理 | 服務上管理 |
（二）openstack定義：
是開源的云計算管理平臺專案，通過各種互補的服務提供了基礎設施即服務（IAAS）的解決方案，每個服務提供API以進行集成，
版本：A~Z命名，docs.openstack.org
openstack架構模塊：
horizon：UI界面，
Neutron：網路
clinder：硬碟
nova：計算
Glance：鏡像
VM:虛擬機
keystone：授權
cellometer：監控
swift：校驗
heat：編排
openst核心組件：
計算：Nova，一套控制器，用于為單個用戶或使用群組管理虛擬機實體的整個生命周期，負責虛擬機創建、開機、關機、掛起、暫停、調整、遷移、重啟、銷毀等操作，
鏡像服務：Glance，一套虛擬機鏡像查找及檢索，支持多種虛擬機鏡像格式（AKI,AMI,ARI,ISO,QCOW2,RAW,VMDK）,有創建上傳鏡像、洗掉鏡像、編輯鏡像基本資訊的功能，
身份服務：keystone，為openstack其他服務提供身份驗證、服務規則和服務令牌功能，管理Domains,Projects,Users,Groups,Roles.
網路&地址管理：Neutron，
塊存盤：Cinder，
UI界面：Horizon，
soa架構介紹：
soa（拆業務）千萬用戶同時訪問，每個網頁都是一個集群，
（三）OpenStack基礎服務的安裝
（1）配置控制節點和計算節點：
[root@computer1 /]# cat /etc/hosts
10.0.0.11 controller
10.0.0.31 computer1
10.0.0.32 computer2
[root@computer1 /]#
（2）配置控制節點和計算節點的yum源：
[root@computer1 etc]# mount /dev/cdrom /mnt/
[root@computer1 etc]# cat /etc/rc.local
mount /dev/cdrom /mnt/
[root@computer1 etc]# chomd +x /etc/rc.local
將資料包里的openstack的rpm上傳至/opt,并解壓
[root@computer1 opt]# cat /etc/yum.repos.d/local.repo
[local]
name=local
baseurl=file:///mnt
gpgcheck=0
[openstack]
name=openstack
baseurl=file:///opt/repo
gpgcheck=0
[root@controller /]# yum makecache
（3）安裝時間同步chrony，并配置：
控制節點：
[root@controller /]# yum install chrony -y
[root@controller /]# vim /etc/chrony.conf
allow 10.0.0.0/24
計算節點：
[root@computer1 /]# yum install chrony -y
[root@computer1 /]# vim /etc/chrony.conf
server 10.0.0.11 iburst
控制節點和計算節點：
[root@computer1 /]# systemctl restart chronyd.service
（4）安裝openstack客戶端和selinux（控制節點和計算節點）
[root@computer1 /]# yum install python-openstackclient.noarch openstack-selinux.noarch
（5）安裝配置mariadb(僅僅控制節點)
[root@controller /]# yum install mariadb mariadb-server.x86_64 python2-PyMySQL.noarch
[root@controller /]# cat >> /etc/my.cnf.d/openstack.cnf << EOF
> [mysqld]
> bind-address = 10.0.0.11
> default-storage-engine = innodb
> innodb_file_per_table
> max_connections = 4096
> collation-server = utf8_general_ci
> character-set-server = utf8
> EOF
[root@controller /]#
[root@controller /]# systemctl start mariadb.service
[root@controller /]# systemctl status mariadb.service
[root@controller /]# systemctl enable mariadb
mysql優化配置：
[root@controller /]# mysql_secure_installation
（6）安裝rabbitmq并創建用戶(僅僅控制節點)
[root@controller /]# yum install rabbitmq-server.noarch -y
[root@controller /]# systemctl start rabbitmq-server.service
[root@controller /]# systemctl status rabbitmq-server.service
[root@controller /]# systemctl enable rabbitmq-server.service
[root@controller /]# rabbitmq-plugins enable rabbitmq_management
[root@controller /]# rabbitmqctl add_user openstack RABBIT_PASS
Creating user "openstack" ...
[root@controller /]# rabbitmqctl set_permissions openstack ".*" ".*" ".*"
Setting permissions for user "openstack" in vhost "/" ...
[root@controller /]# rabbitmq-plugins enable rabbitmq_management
（7）安裝快取memcached（僅僅控制節點）：
[root@controller /]# yum install memcached.x86_64 python-memcached.noarch -y
[root@controller /]# vim /etc/sysconfig/memcached
PORT="11211"
USER="memcached"
MAXCONN="1024"
CACHESIZE="64"
OPTIONS="-l 10.0.0.11,::1"
[root@controller /]# systemctl start memcached.service
[root@controller /]# systemctl enable memcached.service
（四）安裝openstack認證服務keystone
（1）keystone概念
①keystone的主要功能：認證管理，授權管理和服務目錄認證：也可以理解成賬號管理，openstack所有的用戶，都是在keystone上注冊的，
②授權: glance,nova,neutron,cinder等其他服務都統一使用keystone的賬號管理，就像現在很多網站支持qq登陸是一樣的，
③服務目錄：每增加一個服務，都需要在keystone上做注冊登記，用戶通過keystone可以知道由有那些服務，這么服務的url地址是多少，然后用戶就可以直接訪問這些服務，
（2）keystone認證服務
①創庫授權
資料庫授權命令：
grant 權限 on 資料庫物件 to 用戶
grant 權限 on 資料庫物件 to 用戶 identified by ‘密碼'
[root@controller ~]# mysql
MariaDB [(none)]> CREATE DATABASE keystone;
Query OK, 1 row affected (0.00 sec)
MariaDB [(none)]> GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'localhost' \
-> IDENTIFIED BY 'KEYSTONE_DBPASS';
Query OK, 0 rows affected (0.00 sec)
MariaDB [(none)]> GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'%' \
-> IDENTIFIED BY 'KEYSTONE_DBPASS';
Query OK, 0 rows affected (0.00 sec)
MariaDB [(none)]>
②安裝keystone相關軟體包
php,nginx +fastcgi --->php #通過fastcgi 使得nginx去連接php
python,httpd +wsgi--->python #通過wsgi 使得http連接python
[root@controller ~]# yum install openstack-keystone httpd mod_wsgi -y
③修改組態檔
[root@controller ~]# \cp /etc/keystone/keystone.conf{,.bak}
[root@controller ~]# grep -Ev '^$|#' /etc/keystone/keystone.conf.bak >/etc/keystone/keystone.conf
[root@controller ~]# vim /etc/keystone/keystone.conf
方法1:
定義初始管理令牌的值
[DEFAULT]
admin_token = ADMIN_TOKEN
配置資料庫訪問
[database]
connection = mysql+pymysql://keystone:KEYSTONE_DBPASS@controller/keystone
配置Fernet UUID令牌的提供者
[token]
provider = fernet
方法2：
[root@controller keystone]# yum install openstack-utils -y #openstack-utils插件，OpenStack-config命令列配置
openstack-config --set /etc/keystone/keystone.conf DEFAULT admin_token ADMIN_TOKEN
openstack-config --set /etc/keystone/keystone.conf database connection mysql+pymysql://keystone:KEYSTONE_DBPASS@controller/keystone
openstack-config --set /etc/keystone/keystone.conf token provider fernet
③同步資料庫
su -s /bin/sh -c "keystone-manage db_sync" keystone #su切換的是keystone用戶，使用/bin/sh執行命令 keystone-manage db_sync命令，
-s:表示解釋器
-c:表示要執行的命令
keystone：是資料庫用戶名
[root@controller keystone]# su -s /bin/sh -c "keystone-manage db_sync" keystone
檢查表：
[root@controller keystone]# mysql keystone -e "show tables"
查看同步日志：
[root@controller keystone]# vim /var/log/keystone/keystone.log
④初始化fernet
[root@controller keystone]# keystone-manage fernet_setup --keystone-user keystone --keystone-group keystone
[root@controller keystone]# ll /etc/keystone/
drwx------ 2 keystone keystone 24 Jan 4 22:32 fernet-keys
⑤配置httpd(apachd)
優化啟動速度：
[root@controller keystone]# echo "ServerName controller" >>/etc/httpd/conf/httpd.conf
[root@controller keystone]# vim /etc/httpd/conf.d/wsgi-keystone.conf
Listen 5000
Listen 35357
<VirtualHost *:5000>
WSGIDaemonProcess keystone-public processes=5 threads=1 user=keystone group=keystone display-name=%{GROUP}
WSGIProcessGroup keystone-public
WSGIScriptAlias / /usr/bin/keystone-wsgi-public
WSGIApplicationGroup %{GLOBAL}
WSGIPassAuthorization On
ErrorLogFormat "%{cu}t %M"
ErrorLog /var/log/httpd/keystone-error.log
CustomLog /var/log/httpd/keystone-access.log combined
<Directory /usr/bin>
Require all granted
</Directory>
</VirtualHost>
<VirtualHost *:35357>
WSGIDaemonProcess keystone-admin processes=5 threads=1 user=keystone group=keystone display-name=%{GROUP}
WSGIProcessGroup keystone-admin
WSGIScriptAlias / /usr/bin/keystone-wsgi-admin
WSGIApplicationGroup %{GLOBAL}
WSGIPassAuthorization On
ErrorLogFormat "%{cu}t %M"
ErrorLog /var/log/httpd/keystone-error.log
CustomLog /var/log/httpd/keystone-access.log combined

（4）計算服務nova
nova服務是openstack云計算中的最核心服務，
常用組件：
nova-api:接受并回應所有的計算服務請求，管理虛擬機(云主機)生命周期
nova-compute（多個）：真正管理虛擬機的生命周期
nova-scheduler： nova調度器（挑選出最合適的nova-compute來創建虛機）
nova-conductor： 幫助nova-compute代理修改資料庫中虛擬機的狀態
nova-network : 早期openstack版本管理虛擬機的網路（已棄用，neutron）
nova-consoleauth : 為web版的vnc提供訪問令牌
tokennovncproxy：web版 vnc客戶端
nova-api-metadata：接受來自虛擬機發送的元資料請求
openstack通用配置流程：
a：資料庫創庫授權
b：在keystone創建系統用戶關聯角色
c:在keystone上創建服務，注冊api
d：安裝相應服務軟體包
e：修改相應服務的組態檔
f：同步資料庫
g：啟動服務
在控制節點上：
①資料庫創庫授權

（5）網路服務neutron
概念介紹
OpenStack Networking（neutron），允許創建、附加網卡設備，這些設備由其他的OpenStack服務管理，插件式的實作可以容納不同的網路設備和軟體，為OpenStack架構與部署提供了靈活性，
常用組件：
neutron-server :接受和回應外部的網路管理請求
neutron-linuxbridge-agent:負責創建橋接網卡
neutron-dhcp-agent：負責分配IP
neutron-metadata-agent：配合nova-metadata-api實作虛擬機的定制化操作
L3-agent:實作三層網路vxlan(網路層)
①資料庫授權
[root@controller ~]# mysql
CREATE DATABASE neutron;
GRANT ALL PRIVILEGES ON neutron.* TO 'neutron'@'localhost' \
IDENTIFIED BY 'NEUTRON_DBPASS';
GRANT ALL PRIVILEGES ON neutron.* TO 'neutron'@'%' \
IDENTIFIED BY 'NEUTRON_DBPASS';
②在keystone創建系統用戶(glance,nova,neutron)關聯角色
openstack user create --domain default --password NEUTRON_PASS neutron
openstack role add --project service --user neutron admin
③在keystone上創建服務和注冊api
openstack service create --name neutron \

③啟動服務
[root@computer1 ~]# systemctl start httpd.service
④使用瀏覽器http://10.0.0.31/dashboard,
⑤如果出現Internal Server Error
解決辦法：
[root@computer1 ~]# vim /etc/httpd/conf.d/openstack-dashboard.conf
在WSGISocketPrefix run/wsgi后一行添加：
WSGIApplicationGroup %{GLOBAL}
[root@computer1 ~]# systemctl restart httpd.service
⑥登錄dashboard
域：default
用戶名:admin
密碼:ADMIN_PASS
（五）啟動一個實體
第一次啟動實體需要步驟：
1：創建openstack網路
2: 創建實體的硬體配置方案
3：創建密鑰對（控制節點免秘鑰登錄）
4：創建安全組規則
5：啟動一個實體（通過命令列創建實體，或者通過web頁面啟動實體）
（1）通過命令列創建實體
①創建網路
neutron net-create --shared --provider:physical_network provider \
--provider:network_type flat oldboy
# physical_network provider,這里的名稱相同與：
#[root@controller ~]# cat /etc/neutron/plugins/ml2/ml2_conf.ini | grep flat_networks
#flat_networks = provider
創建子網：
neutron subnet-create --name oldgirl \
--allocation-pool start=10.0.0.101,end=10.0.0.250 \
--dns-nameserver 223.5.5.5 --gateway 10.0.0.254 \
oldboy 10.0.0.0/24
②配置硬體配置方案：
查看已有配置方案：
[root@controller ~]# openstack flavor list
[root@controller ~]# openstack flavor create --id 0 --vcpus 1 --ram 64 --disk 1 m1.nano
③創建秘鑰對
[root@controller ~]# ssh-keygen -q -N "" -f ~/.ssh/id_rsa
[root@controller ~]# openstack keypair create --public-key ~/.ssh/id_rsa.pub mykey
④創建安全組規則
openstack security group rule create --proto icmp default
openstack security group rule create --proto tcp --dst-port 22 default
⑤啟動一個實體：
查看已有鏡像：
[root@controller ~]# openstack image list
查看網路id：
[root@controller ~]# neutron net-list
dd7500f9-1cb1-42df-8025-a232ef90d54c
openstack server create --flavor m1.nano --image cirros \
--nic net-id=dd7500f9-1cb1-42df-8025-a232ef90d54c --security-group default \
--key-name mykey oldboy
檢查：
[root@controller images]# openstack server list
[root@controller images]# nova list
注意：
①出現controller無法決議，在電腦的hosts檔案中添加：10.0.0.11 controller
②如果實體卡在gurb界面
計算節點修改配置：
vim /etc/nova/nova.conf
[libvirt]
cpu_mode = none
virt_type = qemu
[root@computer1 ~]# systemctl restart openstack-nova-compute
（2）web頁面創建實體
①點擊“計算”
②點擊“實體”
③點擊右上角“啟用實體”
④詳情資訊：instance name ：實體名稱，count：選擇創建實體數量
⑤選擇鏡像源，點擊加號
⑥flavor：實體的硬體配置，選擇點擊后端加號
⑦網路選擇已經創建的，默認的
⑧下面都是默認
（六）增加一個計算節點
（1）增加計算節點的步驟
1：配置yum源
2: 時間同步
3：安裝openstack基礎包
4：安裝nova-compute
5：安裝neutron-linuxbridge-agent
6：啟動服務nova-compute和linuxbridge-agent
7：驗證
（2）安裝yum
mount /dev/cdrom /mnt
rz 上傳openstack_rpm.tar.gz到/opt，并解壓
生成repo組態檔
echo '[local]
name=local
baseurl=file:///mnt
gpgcheck=0
[openstack]
name=openstack
baseurl=file:///opt/repo
gpgcheck=0' >/etc/yum.repos.d/local.repo
yum makecache
echo 'mount /dev/cdrom /mnt' >>/etc/rc.local
chmod +x /etc/rc.d/rc.local
（3）時間同步和openstack基礎包
時間同步：
vim /etc/chrony.conf

（5）啟動服務
[root@computer2 /]# systemctl start libvirtd openstack-nova-compute neutron-linuxbridge-agent
[root@computer2 /]# systemctl status libvirtd openstack-nova-compute neutron-linuxbridge-agent
（6）創建虛機來檢查新增的計算節點是否可用
①創建主機聚集：管理員-主機聚集-創建主機聚集-主機聚集資訊（名稱，域：oldboyboy）-管理聚集內主機（compute2）--創建
②創建主機：專案-實體-啟動實體-詳細資訊（可用區域選擇剛創建的oldobyboy）-源-flavor-網路-網路埠-安全組-秘鑰對-配置-元資料-創建
注意：如果實體卡在gurb界面
vim /etc/nova/nova.conf
[libvirt]
cpu_mode = none
virt_type = qemu
systemctl restart openstack-nova-compute
（七）openstack用戶專案和角色關系
（1）專案用戶角色的關系圖
創建域
openstack domain create --description "Default Domain" default
創建專案
openstack project create --domain default --description "Admin Project" admin
創建用戶
openstack user create --domain default --password ADMIN_PASS admin
創建角色
openstack role create admin
關聯角色，授權
openstack role add --project admin --user admin admin
（2）身份管理里創建角色（admin，user）
①先創建角色
②創建專案
調整配額，在專案里調整，
③創建用戶
普通用戶里無管理員目錄
admin角色：所有專案管理員
user角色：單個專案的用戶
只用管理員才能看到所有實體，
（八）遷移glance鏡像服務
（1）背景
當openstack管理的計算節點越來越多的時候，控制節點的壓力越來越大，由于所有的服務都安裝在控制節點，這時候控制節點上的openstack服務隨時都團滅的風險，
大家都知道openstack是基于soa架構設計的，我們已經實作了horizon的遷移，接下來，我們實作glance鏡像服務的遷移，后面其他的服務都可以遷移，讓控制節點只保留一個keystone服務，是soa架構的最佳實踐，
本次，我們將glance鏡像服務，由控制節點遷移到compute2上，
（2）glance鏡像服務遷移的主要步驟
1：停止控制節點上的glance服務
2：備份遷移glance資料庫
3：在新的節點上安裝配置glance
4：遷移原有glance鏡像檔案
5：修改keystone中glance的api地址
6：修改所有節點nova組態檔中glance的api地址
7：測驗，上傳鏡像，創建實體
（3）操作程序
①控制節點上關閉相關服務：
[root@controller ~]# systemctl stop openstack-glance-api.service openstack-glance-registry.service
[root@controller ~]# systemctl disable openstack-glance-api.service openstack-glance-registry.service
②在控制節點上備份庫：
[root@controller ~]# mysqldump -uroot -B glance >glance.sql
[root@controller ~]# scp glance.sql 10.0.0.32:/root
（4）資料庫遷移
在compute2上：
yum install mariadb-server.x86_64 python2-PyMySQL -y
systemctl start mariadb
systemctl enable mariadb
mysql_secure_installation
匯入從控制節點上備份的glance資料庫
mysql < glance.sql
[root@computer2 ~]# mysql
mysql>
show databases;
GRANT ALL PRIVILEGES ON glance.* TO 'glance'@'localhost' \
IDENTIFIED BY 'GLANCE_DBPASS';
GRANT ALL PRIVILEGES ON glance.* TO 'glance'@'%' \
IDENTIFIED BY 'GLANCE_DBPASS';
（5）安裝glance服務
在compute2上安裝：
yum install openstack-glance -y
在控制節點上將組態檔發送至compute2上：
[root@controller ~]# scp /etc/glance/glance-api.conf 10.0.0.32:/etc/glance/
[root@controller ~]# scp /etc/glance/glance-registry.conf 10.0.0.32:/etc/glance/
修改：
connection = mysql+pymysql://glance:[email protected]/glance
復制之前的內容，注意：修改資料庫的ip地址為10.0.0.32
systemctl start openstack-glance-api.service openstack-glance-registry.service
systemctl enable openstack-glance-api.service openstack-glance-registry.service
（6）遷移鏡像
[root@computer2 glance]# scp -rp 10.0.0.11:/var/lib/glance/images/* /var/lib/glance/images/
[root@computer2 images]# chown -R glance:glance /var/lib/glance/images/
在控制節點上檢查：
source admin-openrc
openstack endpoint list | grep image
依舊是之前的鏡像
（7）修改keystone上的glance的api地址
在控制節點上：
查看相關資料庫：
msyql keystone:
select * from endpoint
[root@controller ~]# mysqldump -uroot keystone endpoint >endpoint.sql
[root@controller ~]# cp endpoint.sql /opt/
修改資料庫組態檔：
[root@controller ~]# sed -i 's#http://controller:9292#http://10.0.0.32:9292#g' endpoint.sql
匯入修改好的資料庫檔案：
[root@controller ~]# mysql keystone < endpoint.sql
查看glance介面地址：
[root@controller ~]# openstack endpoint list|grep image
[root@controller ~]# openstack image list
（8）修改所有節點nova組態檔
sed -i 's#http://controller:9292#http://10.0.0.32:9292#g' /etc/nova/nova.conf
grep '9292' /etc/nova/nova.conf
systemctl restart openstack-nova-api.service openstack-nova-compute.service
控制節點重啟：openstack-nova-api.service
計算節點重啟：openstack-nova-compute.service
控制節點：
[root@controller ~]# nova service-list
+----+------------------+------------+-----------+---------+-------+----------------------------+-----------------+
| Id | Binary | Host | Zone | Status | State | Updated_at | Disabled Reason |
+----+------------------+------------+-----------+---------+-------+----------------------------+-----------------+

| 2 | nova-consoleauth | controller | internal | enabled | up | 2020-01-05T16:53:10.000000 | - |
| 3 | nova-scheduler | controller | internal | enabled | up | 2020-01-05T16:53:10.000000 | - |
| 6 | nova-compute | computer1 | nova | enabled | up | 2020-01-05T16:53:08.000000 | - |
| 7 | nova-compute | computer2 | oldboyboy | enabled | up | 2020-01-05T16:53:08.000000 | - |
+----+------------------+------------+-----------+---------+-------+----------------------------+-----------------+
（9）測驗，上傳鏡像，創建實體
上傳鏡像：
專案-鏡像-創建鏡像
創建實體：
專案-實體-啟用實體
web頁面；專案里可以上傳鏡像
qemu-img info .. #查看鏡像資訊
（10）安裝cinder塊服務
①塊存盤服務cinder的介紹
塊存盤服務（cinder）為實體提供塊存盤，存盤的分配和消耗是由塊存盤驅動器，或者多后端配置的驅動器決定的，還有很多驅動程式可用：NAS/SAN，NFS，LVM，Ceph等，常用組件：cinder-api: 接收和回應外部有關塊存盤請求c
inder-volume： 提供存盤空間
cinder-scheduler：調度器，決定將要分配的空間由哪一個cinder-volume提供，
cinder-backup： 備份卷
②openstack服務通用安裝步驟
a：資料庫創庫授權
b：在keystone創建系統用戶關聯角色
c：在keystone上創建服務，注冊api
d：安裝相應服務軟體包
e：修改相應服務的組態檔
f：同步資料庫
g：啟動服務
③cinder塊存盤服務控制節點

?創卷卷組型別
已定義卷組型別：
volume_backend_name = ssd
volume_backend_name = sata
管理員-卷-創建型別卷-名稱-查看卷型別-已創建-分別在鍵和值里填寫以上資訊，
專案-卷-創建卷-創建卷程序中可以選擇已經創建好的卷型別，lvs查看創建情況
（12）增加一個flat網路
分別在三臺機器上增加一個網卡，選擇lan網段，地址172.16.0.0/24
①增加一個flat網路原因
我們的openstack當前環境只有一個基于eth0網卡橋接的，它能使用的ip范圍有限，就決定著它能創建的實體數量有限，無法超過可用ip的數量，當我們的openstack私有云規模比較大的時候，這時候只有一個網路，就不能滿足我們的需求了，所以這里我們來學習如何增加一個網路我們使用的環境是VMware workstation，無法模擬vlan的場景，所以這里我們繼續使用flat，網路型別，
②添加網卡eth1
分別虛擬機上添加一塊網卡，為lan區段，172.16.0.0/24
拷貝ifcfg-eth0 至ifcfg-eth1,修改eth1的地址為172.16.0.0/24地址段，并ifup eth1啟動網卡，
[root@computer1 network-scripts]# scp ifcfg-eth1 10.0.0.11:pwd
③控制節點配置
1:控制節點
a:
vim /etc/neutron/plugins/ml2/ml2_conf.ini
[ml2_type_flat]
flat_networks = provider,net172_16
b:
vim /etc/neutron/plugins/ml2/linuxbridge_agent.ini
[linux_bridge]
physical_interface_mappings = provider:eth0,net172_16:eth1
c：重啟
systemctl restart neutron-server.service neutron-linuxbridge-agent.service
④計算節點配置
a:
vim /etc/neutron/plugins/ml2/linuxbridge_agent.ini
[linux_bridge]
physical_interface_mappings = provider:eth0,net172_16:eth1
b：重啟
systemctl restart neutron-linuxbridge-agent.service
檢測：控制節點
neutron agent-list
⑤創建網路
命令列創建：
neutron net-create --shared --provider:physical_network net172_16 \
--provider:network_type flat net172_16
neutron subnet-create --name oldgirl \
--allocation-pool start=172.16.0.1,end=172.16.0.250 \
--dns-nameserver 223.5.5.5 --gateway 172.16.0.254 \
net172_16 172.16.0.0/24
web頁面創建網路：
管理員-網路-創建網路（供應商，平面）-創建子網
創建實體：專案-實體-創建實體（創建程序中可以選擇剛創建的網路）
注意：創建一個linux系統作為路由器使用：
基于net172_16網路上網，路由器服務器需要配置：
配置eth0和eth1,但是eth1的網路地址為172.16.0.254,為虛擬機網關地址，不配置網關，
編輯內核組態檔，開啟轉發
vim /etc/sysctl.conf
net.ipv4.ip_forward = 1
使內核生效
sysctl -p
清空防火墻的filter表
iptables -F
#添加轉發規則
iptables -t nat -A POSTROUTING -s 172.16.0.0/24 -j MASQUERADE
（13）cinder對接nfs共享存盤
①cinder使用nfs做后端存盤
cinder服務和nova服務很相似
nova：不提供虛擬化，支持多種虛擬化技術，kvm,xen,qemu,lxc
cinder：不提供存盤，支持多種存盤技術，lvm，nfs，glusterFS，ceph
后期如果需要對接其他型別后端存盤，方法都類似，
②前提條件控制節點安裝nfs
安裝
[root@controller ~]# yum install nfs-utils.x86_64 -y
配置
[root@controller ~]# mkdir /data
[root@controller ~]# vim /etc/exports
/data 10.0.0.0/24(rw,async,no_root_squash,no_all_squash)
啟動
[root@controller ~]# systemctl restart rpcbind.socket
[root@controller ~]# systemctl restart nfs
③存盤節點的配置
[root@computer1 ~]# yum install nfs -y
修改/etc/cinder/cinder.conf
[DEFAULT]
enabled_backends = sata,ssd,nfs
[nfs]
volume_driver = cinder.volume.drivers.nfs.NfsDriver
nfs_shares_config = /etc/cinder/nfs_shares
volume_backend_name = nfs
vi /etc/cinder/nfs_shares
10.0.0.11:/data
[root@computer1 ~]# showmount -e 10.0.0.11
Export list for 10.0.0.11:
/data 10.0.0.0/24
重啟cinder-volume
systemctl restart openstack-cinder-volume.service
在控制節點上檢查：cinder service-list
查看卷日志：
[root@computer1 ~]# vim /var/log/cinder/volume.log
有事報錯,需要：
[root@computer1 ~]# chown -R cinder:cinder /var/lib/cinder/mnt/

計算節點2：
計算節點1是以root發送的，所以在計算節點1上都是root用戶屬主：
[root@computer1 ~]# chown -R nova:nova /var/lib/nova
控制節點配置：
[root@controller ~]# vim /etc/nova/nova.conf
[DEFAULT]
cheduler_default_filters=RetryFilter,AvailabilityZoneFilter,RamFilter,DiskF

（15）openstack新建云主機流程
流程圖要說清楚，
（16）openstack定制云主機
思考：為什么基于同一個鏡像模板啟動的云主機，云主機的主機名和實體名稱一樣？
思考：為什么在控制節點上可以免密碼登陸我們的云主機？
思考：控制節點nova的組態檔中，需要配置下面紅色標記的兩行？
vi /etc/nova/nova.com

（17）openstack三層網路vxlan
思考：為什么現在的公有云買的云主機，使用公網ip地址連接后，看到的卻是一個私網ip？
思考：公有云上每一個用戶都可以建立多個vpc網路，云廠商如何實作這么多vpc網路的隔離？
使用vlan的話，最多產生1-4094個隔離的網路
使用vxlan的話，最多產生4096*4096-2約等于1678萬個隔離的網路
①為所有節點，增加一塊網卡，作為vxlan網路的隧道通信ip
三層網路vxlan控制節點配置步驟1
[root@controller ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth2
TYPE=Ethernet
BOOTPROTO=none
NAME=eth2
DEVICE=eth2
ONBOOT=yes
IPADDR=172.16.1.11
NETMASK=255.255.255.0
GATEWAY=172.16.1.254
DNS1=223.5.5.5
[root@controller ~]#ifup eth2
②三層網路vxlan控制節點配置步驟2
修改控制節點/etc/neutron/neutron.conf檔案
[DEFAULT]
...
core_plugin = ml2
service_plugins =
修改為：
[root@controller ~]# vim /etc/neutron/neutron.conf
[DEFAULT]
core_plugin = ml2
service_plugins = router
allow_overlapping_ips = True
③三層網路vxlan控制節點配置步驟3
將/etc/neutron/plugins/ml2/ml2_conf.ini修改為
[DEFAULT]
[ml2]
type_drivers = flat,vlan,vxlan
tenant_network_types = vxlan
mechanism_drivers = linuxbridge,l2population
extension_drivers = port_security
[ml2_type_flat]

[ml2_type_geneve]
[ml2_type_gre]
[ml2_type_vlan]
[ml2_type_vxlan]
vni_ranges = 1:100000
[securitygroup]
enable_ipset = True
④三層網路vxlan控制節點配置步驟4
將/etc/neutron/plugins/ml2/linuxbridge_agent.ini修改為
[DEFAULT]
[agent]
[linux_bridge]
physical_interface_mappings = provider:eth0,net172_16:eth1
[securitygroup]
enable_security_group = True
firewall_driver = neutron.agent.linux.iptables_firewall.IptablesFirewallDriver
[vxlan]
enable_vxlan = True
local_ip = 172.16.1.11
l2_population = True
⑤三層網路vxlan控制節點配置步驟5
將/etc/neutron/l3_agent.ini修改為
[DEFAULT]
interface_driver = neutron.agent.linux.interface.BridgeInterfaceDriver
external_network_bridge =
[AGENT]
啟動服務：
systemctl restart neutron-server.service neutron-linuxbridge-agent.service neutron-dhcp-agent.service neutron-metadata-agent.service
systemctl enable neutron-l3-agent.service
systemctl start neutron-l3-agent.service
⑥計算節點：三層網路vxlan計算節點配置步驟
將/etc/neutron/plugins/ml2/linuxbridge_agent.ini修改為
[DEFAULT]
[agent]
[linux_bridge]
physical_interface_mappings = provider:eth0,net172_16:eth1
[securitygroup]
enable_security_group = True
firewall_driver = neutron.agent.linux.iptables_firewall.IptablesFirewallDriver
[vxlan]
enable_vxlan = True
local_ip = 172.16.1.31
l2_population = True
systemctl restart neutron-linuxbridge-agent.service
在控制節點查看：
[root@controller ~]# neutron agent-list
⑦web界面操作
步驟1：修改oldboy外網為外部網路，管理員-網路-oldbly-編輯網路-修改為外部網路
步驟2：創建一個內部測驗網路，專案-網路-創建網路（test，192.168.1.0/24）
步驟3：開啟外部網路的路由功能，在computer1上：
[root@computer1 ~]# vim /etc/openstack-dashboard/local_settings
OPENSTACK_NEUTRON_NETWORK = {
'enable_router': True,
重啟apache：
[root@computer1 ~]# systemctl restart httpd
在web頁面中：網路中，多了一個路由器，
步驟4：使用oldboy用戶創建一個網路，專案-網路-創建網路（test內部網路）
步驟5：使用oldboy用戶創建一個路由器，專案-網路-路由器（testr）,在路由器添加介面外部和內部介面，
步驟6:admin用戶創建兩個實體，使用內部網路創建，ping www.baidu.com
