前言：python

openstack的部署很是簡單，簡單的前提創建在紮實的理論功底，本人一直以爲，玩技術必定是理論指導實踐，網上遍及個種搭建方法均可以實現一個基本的私有云環境，可是諸位可曾發現，不少配置都是重複的，爲什麼重複？到底什麼位置該不應配？具體配置什麼參數？不少做者本人都搞不清楚，今天本人就是要在這裏正本清源（由於你不理解因此你會有冗餘的配置，說白了，啥配置啥意思你根本沒鬧明白）。mysql

若有不解可郵件聯繫我：egonlin4573@gmail.comlinux

介紹：本次案列爲基本的三節點部署，集羣案列後期有時間再整理sql

一：網絡（本次實驗沒有作Cinder節點）：mongodb

1.管理網絡：172.16.209.0/24數據庫

2.數據網絡：1.1.1.0/24apache

二：操做系統：CentOS Linux release 7.2.1511 (Core)django

三：內核：3.10.0-327.el7.x86_64vim

四：openstack版本mitaka

效果圖：

OpenStack mitaka部署

約定：

0.如下配置是在原有配置文件上找相關項進行修改或添加

1.在修改配置的時候，切勿在某條配置後加上註釋，能夠在配置的上面或者下面加註釋

2.相關配置必定是在標題後追加，不要在原有註釋的基礎上修改

PART1：環境準備

一：

1：每臺機器設置固定ip，每臺機器添加hosts文件解析，爲每臺機器設置主機名，關閉firewalld，selinux

/etc/hosts

127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4

::1 localhost localhost.localdomain localhost6 localhost6.localdomain6

172.16.209.115 controller01

172.16.209.117 compute01

172.16.209.119 network02

其中 network02三塊網卡，其餘的兩塊

2.每臺機器配置yum源，可不配置，，使用默認的CentOS repo

[mitaka]

name=mitaka repo

baseurl=http://172.16.209.100/mitaka-rpms/

enabled=1

gpgcheck=0

3.每臺機器

yum makecache && yum install vim net-tools -y&& yum update -y

4.時間服務部署

全部節點：

yum install chrony -y

控制節點：

修改配置：

/etc/chrony.conf

server ntp.staging.kycloud.lan iburst

allow 管理網絡網段ip/24

啓服務：

systemctl enable chronyd.service

systemctl start chronyd.service

其他節點：

修改配置：

/etc/chrony.conf

server 控制節點ip iburst

啓服務

systemctl enable chronyd.service

systemctl start chronyd.service

時區不是Asia/Shanghai須要改時區：

# timedatectl set-local-rtc 1 # 將硬件時鐘調整爲與本地時鐘一致, 0 爲設置爲 UTC 時間

# timedatectl set-timezone Asia/Shanghai # 設置系統時區爲上海

其實不考慮各個發行版的差別化, 從更底層出發的話, 修改時間時區比想象中要簡單:

# cp /usr/share/zoneinfo/Asia/Shanghai /etc/localtime

驗證：

每臺機器執行：

chronyc sources

在S那一列包含*號，表明同步成功（可能須要花費幾分鐘去同步，時間務必同步）

二：獲取軟件包

若是使用自定義源，那麼下列centos和redhat的操做能夠省略

#在全部節點執行

centos：

yum install yum-plugin-priorities -y #防止自動更新

yum install centos-release-openstack-mitaka -y #若是不使用個人自定義yum那麼請執行這一步

redhat：

yum install yum-plugin-priorities -y

yum install https://rdoproject.org/repos/rdo-release.rpm -y

紅帽系統請去掉epel源

#在全部節點執行

yum upgrade

yum install python-openstackclient -y

yum install openstack-selinux -y

三：部署mariadb數據庫

控制節點：

yum install mariadb mariadb-server python2-PyMySQL -y

編輯：

/etc/my.cnf.d/openstack.cnf

[mysqld]

bind-address = 控制節點管理網絡ip

default-storage-engine = innodb

innodb_file_per_table

max_connections = 4096

collation-server = utf8_general_ci

character-set-server = utf8

啓服務：

systemctl enable mariadb.service

systemctl start mariadb.service

mysql_secure_installation

四：爲Telemetry 服務部署MongoDB

控制節點：

yum install mongodb-server mongodb -y

編輯：/etc/mongod.conf

bind_ip = 控制節點管理網絡ip

smallfiles = true

啓動服務：

systemctl enable mongod.service

systemctl start mongod.service

五：部署消息隊列rabbitmq

控制節點：

yum install rabbitmq-server -y

啓動服務：

systemctl enable rabbitmq-server.service

systemctl start rabbitmq-server.service

新建rabbitmq用戶密碼：

rabbitmqctl add_user openstack che001

rabbitmqctl delete_user guest

爲新建的用戶openstack設定權限：

rabbitmqctl set_permissions openstack ".*" ".*" ".*"

啓動管理WEB

rabbitmq-plugins enable rabbitmq_management

(驗證方式:http://172.16.209.104:15672/ 用戶:openstack 密碼:che001)

六：部署memcached緩存（爲keystone服務緩存tokens）

控制節點：

yum install memcached python-memcached -y

cat /etc/sysconfig/memcached

PORT="11211"
USER="memcached" MAXCONN="10240" CACHESIZE="64" #OPTIONS="-l 127.0.0.1,::1" OPTIONS="-l 0.0.0.0"

啓動服務：

systemctl enable memcached.service

systemctl start memcached.service

PART2：認證服務keystone部署

一：安裝和配置服務

1.建庫建用戶

mysql -u root -p

CREATE DATABASE keystone;

GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'localhost' \

IDENTIFIED BY 'che001';

GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'%' \

IDENTIFIED BY 'che001';

flush privileges;

2.yum install openstack-keystone httpd mod_wsgi -y

3.編輯/etc/keystone/keystone.conf

[DEFAULT]

admin_token = che001

#建議用命令製做token:openssl rand -hex 10

#這裏的做用主要是先手動指定admin_token，爲了部署keystone，由於keystone沒部署，認證環節還不能工做，等keystone部署好，會把手動指定admin_token認證方式去掉

[database]

connection = mysql+pymysql://keystone:che001@controller01/keystone

[token]

provider = fernet

#Token Provider：UUID, PKI, PKIZ, or Fernet #http://blog.csdn.net/miss_yang_cloud/article/details/49633719

4.同步修改到數據庫

su -s /bin/sh -c "keystone-manage db_sync" keystone

5.初始化fernet keys

keystone-manage fernet_setup --keystone-user keystone --keystone-group keystone

6.配置apache服務

編輯：/etc/httpd/conf/httpd.conf

ServerName controller01

編輯：/etc/httpd/conf.d/wsgi-keystone.conf

新增配置

Listen 5000

Listen 35357

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

Require all granted

</Directory>

</VirtualHost>

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

Require all granted

</Directory>

</VirtualHost>

7.啓動服務:

systemctl enable httpd.service

systemctl start httpd.service

二：建立服務實體和訪問端點

1.實現配置管理員環境變量，用於獲取後面建立的權限

export OS_TOKEN=che001

#要與前面的/etc/keystone/keystone.conf中的admin_token相同

export OS_URL=http://controller01:35357/v3

export OS_IDENTITY_API_VERSION=3

2.基於上一步給的權限，建立認證服務實體（目錄服務）

openstack service create --name keystone --description "OpenStack Identity" identity

#如遇到報500錯誤，ArgsAlreadyParsedError: arguments already parsed: cannot register CLI option，可把--description "OpenStack Identity"去掉

3.基於上一步創建的服務實體，建立訪問該實體的三個api端點

openstack endpoint create --region RegionOne \

identity public http://controller01:5000/v3

openstack endpoint create --region RegionOne \

identity internal http://controller01:5000/v3

openstack endpoint create --region RegionOne \

identity admin http://controller01:35357/v3

三：建立域，租戶，用戶，角色，把四個元素關聯到一塊兒

創建一個公共的域名：

openstack domain create --description "Default Domain" default

管理員：admin

openstack project create --domain default \

--description "Admin Project" admin

openstack user create --domain default \

--password-prompt admin

openstack role create admin

openstack role add --project admin --user admin admin

普通用戶：demo

openstack project create --domain default \

--description "Demo Project" demo

openstack user create --domain default \

--password-prompt demo

openstack role create user

openstack role add --project demo --user demo user

爲後續的服務建立統一租戶service

解釋：後面每搭建一個新的服務都須要在keystone中執行四種操做：1.建租戶 2.建用戶 3.建角色 4.作關聯

後面全部的服務公用一個租戶service，都是管理員角色admin，因此實際上後續的服務安裝關於keysotne

的操做只剩2，4

openstack project create --domain default \

--description "Service Project" service

四：驗證操做：

編輯：/etc/keystone/keystone-paste.ini

在[pipeline:public_api], [pipeline:admin_api], and [pipeline:api_v3] 三個地方

移走：admin_token_auth

keystone部署好後，可使用用戶名密碼進行驗證產生token了，不須要手動指定admin_token了

unset OS_TOKEN OS_URL

openstack --os-auth-url http://controller01:35357/v3 \

--os-project-domain-name default --os-user-domain-name default \

--os-project-name admin --os-username admin token issue

Password: (輸入openstack user create --domain default --password-prompt admin爲admin設置的密碼)

五：新建客戶端腳本文件

管理員：admin-openrc

export OS_PROJECT_DOMAIN_NAME=default

export OS_USER_DOMAIN_NAME=default

export OS_PROJECT_NAME=admin

export OS_USERNAME=admin

export OS_PASSWORD=che001

export OS_AUTH_URL=http://controller01:35357/v3

export OS_IDENTITY_API_VERSION=3

export OS_IMAGE_API_VERSION=2

普通用戶demo：demo-openrc

export OS_PROJECT_DOMAIN_NAME=default

export OS_USER_DOMAIN_NAME=default

export OS_PROJECT_NAME=demo

export OS_USERNAME=demo

export OS_PASSWORD=che001

export OS_AUTH_URL=http://controller01:5000/v3

export OS_IDENTITY_API_VERSION=3

export OS_IMAGE_API_VERSION=2

效果：

source admin-openrc

[root@controller01 ~]# openstack token issue

part3：部署鏡像服務

一：安裝和配置服務

1.建庫建用戶

mysql -u root -p

CREATE DATABASE glance;

GRANT ALL PRIVILEGES ON glance.* TO 'glance'@'localhost' \

IDENTIFIED BY 'che001';

GRANT ALL PRIVILEGES ON glance.* TO 'glance'@'%' \

IDENTIFIED BY 'che001';

flush privileges;

2.keystone認證操做：

上面提到過：全部後續項目的部署都統一放到一個租戶service裏，而後須要爲每一個項目創建用戶，建管理員角色，創建關聯

. admin-openrc

openstack user create --domain default --password-prompt glance

openstack role add --project service --user glance admin

創建服務實體

openstack service create --name glance \

--description "OpenStack Image" image

建端點

openstack endpoint create --region RegionOne \

image public http://controller01:9292

openstack endpoint create --region RegionOne \

image internal http://controller01:9292

openstack endpoint create --region RegionOne \

image admin http://controller01:9292

3.安裝軟件

yum install openstack-glance -y

4.修改配置：

編輯：/etc/glance/glance-api.conf

[database]

#這裏的數據庫鏈接配置是用來初始化生成數據庫表結構,不配置沒法生成數據庫表結構

#glance-api不配置database對建立vm無影響，對使用metada有影響

#日誌報錯:ERROR glance.api.v2.metadef_namespaces

connection = mysql+pymysql://glance:che001@controller01/glance

[keystone_authtoken]

auth_url = http://controller01:5000

memcached_servers = controller01:11211

auth_type = password

project_domain_name = default

user_domain_name = default

project_name = service

username = glance

password = che001

[paste_deploy]

flavor = keystone

[glance_store]

stores = file,http

default_store = file

filesystem_store_datadir = /var/lib/glance/images/

編輯：/etc/glance/glance-registry.conf

[database]

#這裏的數據庫配置是用來glance-registry檢索鏡像元數據

connection = mysql+pymysql://glance:che001@controller01/glance

新建目錄：

mkdir /var/lib/glance/images/

chown glance. /var/lib/glance/images/

同步數據庫：（此處會報一些關於future的問題，自行忽略）

su -s /bin/sh -c "glance-manage db_sync" glance

啓動服務：

systemctl enable openstack-glance-api.service \

openstack-glance-registry.service

systemctl start openstack-glance-api.service \

openstack-glance-registry.service

二：驗證操做：

. admin-openrc

wget http://download.cirros-cloud.net/0.3.4/cirros-0.3.4-x86_64-disk.img

（本地下載：wget http://172.16.209.100/cirros-0.3.4-x86_64-disk.img）

openstack image create "cirros" \

--file cirros-0.3.4-x86_64-disk.img \

--disk-format qcow2 --container-format bare \

--public

openstack image list

part4：部署compute服務

一：控制節點配置

1.建庫建用戶

CREATE DATABASE nova_api;

CREATE DATABASE nova;

GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'localhost' \

IDENTIFIED BY 'che001';

GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'%' \

IDENTIFIED BY 'che001';

GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'localhost' \

IDENTIFIED BY 'che001';

GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'%' \

IDENTIFIED BY 'che001';

flush privileges;

2.keystone相關操做

. admin-openrc

openstack user create --domain default \

--password-prompt nova

openstack role add --project service --user nova admin

openstack service create --name nova \

--description "OpenStack Compute" compute

openstack endpoint create --region RegionOne \

compute public http://controller01:8774/v2.1/%\(tenant_id\)s

openstack endpoint create --region RegionOne \

compute internal http://controller01:8774/v2.1/%\(tenant_id\)s

openstack endpoint create --region RegionOne \

compute admin http://controller01:8774/v2.1/%\(tenant_id\)s

3.安裝軟件包：

yum install openstack-nova-api openstack-nova-conductor \

openstack-nova-console openstack-nova-novncproxy \

openstack-nova-scheduler -y

4.修改配置：

編輯/etc/nova/nova.conf

[DEFAULT]

enabled_apis = osapi_compute,metadata

rpc_backend = rabbit

auth_strategy = keystone

#下面的爲管理ip

my_ip = 172.16.209.115

use_neutron = True

firewall_driver = nova.virt.firewall.NoopFirewallDriver

[api_database]

connection = mysql+pymysql://nova:che001@controller01/nova_api

[database]

connection = mysql+pymysql://nova:che001@controller01/nova

[oslo_messaging_rabbit]

rabbit_host = controller01

rabbit_userid = openstack

rabbit_password = che001

[keystone_authtoken]

auth_url = http://controller01:5000

memcached_servers = controller01:11211

auth_type = password

project_domain_name = default

user_domain_name = default

project_name = service

username = nova

password = che001

[vnc]

#下面的爲管理ip

vncserver_listen = 172.16.209.115

#下面的爲管理ip

vncserver_proxyclient_address = 172.16.209.115

[oslo_concurrency]

lock_path = /var/lib/nova/tmp

5.同步數據庫：（此處會報一些關於future的問題，自行忽略）

su -s /bin/sh -c "nova-manage api_db sync" nova

su -s /bin/sh -c "nova-manage db sync" nova

6.啓動服務

systemctl enable openstack-nova-api.service \

openstack-nova-consoleauth.service openstack-nova-scheduler.service \

openstack-nova-conductor.service openstack-nova-novncproxy.service

systemctl start openstack-nova-api.service \

openstack-nova-consoleauth.service openstack-nova-scheduler.service \

openstack-nova-conductor.service openstack-nova-novncproxy.service

[glance]

api_servers = http://controller01:9292

[oslo_concurrency]

lock_path = /var/lib/nova/tmp

3.若是在不支持虛擬化的機器上部署nova，請確認

egrep -c '(vmx|svm)' /proc/cpuinfo結果爲0

則編輯/etc/nova/nova.conf

[libvirt]

virt_type = qemu

4.啓動服務

systemctl enable libvirtd.service openstack-nova-compute.service

systemctl start libvirtd.service openstack-nova-compute.service

三：驗證

控制節點

[root@controller01 ~]# source admin-openrc

[root@controller01 ~]# openstack compute service list

+----+------------------+--------------+----------+---------+-------+----------------------------+

part5：部署網絡服務

一：控制節點配置

1.建庫建用戶

CREATE DATABASE neutron;

GRANT ALL PRIVILEGES ON neutron.* TO 'neutron'@'localhost' \

IDENTIFIED BY 'che001';

GRANT ALL PRIVILEGES ON neutron.* TO 'neutron'@'%' \

IDENTIFIED BY 'che001';

flush privileges;

2.keystone相關

. admin-openrc

openstack user create --domain default --password-prompt neutron

openstack role add --project service --user neutron admin

openstack service create --name neutron \

--description "OpenStack Networking" network

network public http://controller01:9696

openstack endpoint create --region RegionOne \

network internal http://controller01:9696

openstack endpoint create --region RegionOne \

network admin http://controller01:9696

3.安裝軟件包

yum install openstack-neutron openstack-neutron-ml2 python-neutronclient which -y

4.配置服務器組件

編輯 /etc/neutron/neutron.conf文件,並完成如下動做:

在[數據庫]節中,配置數據庫訪問:

[DEFAULT]

core_plugin = ml2

service_plugins = router

#下面配置:啓用重疊IP地址功能

allow_overlapping_ips = True

rpc_backend = rabbit

auth_strategy = keystone

notify_nova_on_port_status_changes = True

notify_nova_on_port_data_changes = True

[oslo_messaging_rabbit]

rabbit_host = controller01

rabbit_userid = openstack

rabbit_password = che001

[database]

connection = mysql+pymysql://neutron:che001@controller01/neutron

[keystone_authtoken]

auth_url = http://controller01:5000

memcached_servers = controller01:11211

auth_type = password

project_domain_name = default

user_domain_name = default

project_name = service

username = neutron

password = che001

[nova]

auth_url = http://controller01:5000

auth_type = password

project_domain_name = default

user_domain_name = default

region_name = RegionOne

project_name = service

username = nova

password = che001

[oslo_concurrency]

lock_path = /var/lib/neutron/tmp

編輯/etc/neutron/plugins/ml2/ml2_conf.ini文件

[ml2]

type_drivers = flat,vlan,vxlan,gre

tenant_network_types = vxlan

mechanism_drivers = openvswitch,l2population

extension_drivers = port_security

[ml2_type_flat]

flat_networks = provider

[ml2_type_vxlan]

vni_ranges = 1:1000

[securitygroup]

enable_ipset = True

編輯/etc/nova/nova.conf文件：

[neutron]

url = http://controller01:9696

auth_url = http://controller01:5000

auth_type = password

project_domain_name = default

user_domain_name = default

region_name = RegionOne

project_name = service

username = neutron

password = che001

service_metadata_proxy = True

5.建立鏈接

ln -s /etc/neutron/plugins/ml2/ml2_conf.ini /etc/neutron/plugin.ini

6.同步數據庫：（此處會報一些關於future的問題，自行忽略）

su -s /bin/sh -c "neutron-db-manage --config-file /etc/neutron/neutron.conf \

--config-file /etc/neutron/plugins/ml2/ml2_conf.ini upgrade head" neutron

7.重啓nova服務

systemctl restart openstack-nova-api.service

8.啓動neutron服務

systemctl enable neutron-server.service

systemctl start neutron-server.service

二：網絡節點配置

1. 編輯 /etc/sysctl.conf

net.ipv4.ip_forward=1

net.ipv4.conf.all.rp_filter=0

net.ipv4.conf.default.rp_filter=0

2.執行下列命令，當即生效

sysctl -p

3.安裝軟件包

yum install openstack-neutron openstack-neutron-ml2 openstack-neutron-openvswitch -y

4．配置組件

編輯/etc/neutron/neutron.conf文件

[DEFAULT]

core_plugin = ml2

service_plugins = router

allow_overlapping_ips = True

rpc_backend = rabbit

auth_strategy = keystone

[oslo_messaging_rabbit]

rabbit_host = controller01

rabbit_userid = openstack

rabbit_password = che001

[oslo_concurrency]

lock_path = /var/lib/neutron/tmp

六、編輯 /etc/neutron/plugins/ml2/openvswitch_agent.ini文件:

[ovs]

#下面ip爲網絡節點數據網絡ip

local_ip=1.1.1.119

bridge_mappings=external:br-ex

[agent]

tunnel_types=gre,vxlan

l2_population=True

prevent_arp_spoofing=True

7.配置L3代理。編輯 /etc/neutron/l3_agent.ini文件:

[DEFAULT]

interface_driver=neutron.agent.linux.interface.OVSInterfaceDriver

external_network_bridge=br-ex

8.配置DHCP代理。編輯 /etc/neutron/dhcp_agent.ini文件:

[DEFAULT]

interface_driver=neutron.agent.linux.interface.OVSInterfaceDriver

dhcp_driver=neutron.agent.linux.dhcp.Dnsmasq

enable_isolated_metadata=True

9.配置元數據代理。編輯 /etc/neutron/metadata_agent.ini文件:

[DEFAULT]

nova_metadata_ip=controller01

metadata_proxy_shared_secret=che001

10.啓動服務

網路節點：

systemctl start neutron-openvswitch-agent.service neutron-l3-agent.service \

neutron-dhcp-agent.service neutron-metadata-agent.service

systemctl enable neutron-openvswitch-agent.service neutron-l3-agent.service \

neutron-dhcp-agent.service neutron-metadata-agent.service

12.建網橋

ovs-vsctl add-br br-ex

ovs-vsctl add-port br-ex eth2

（br-ex、eth2能夠不設置IP，有三塊網卡不用作如下設置）

注意，若是網卡數量有限，想用網路節點的管理網絡網卡做爲br-ex綁定的物理網卡

#那麼須要將網絡節點管理網絡網卡ip去掉，創建br-ex的配置文件，ip使用原管理網ip

ovs-vsctl add-br br-ex

[root@network01 ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth0

DEVICE="eno16777736"

TYPE=Ethernet

ONBOOT="yes"

BOOTPROTO="none"

[root@network01 ~]# cat /etc/sysconfig/network-scripts/ifcfg-br-ex

DEVICE=br-ex

TYPE=Ethernet

ONBOOT="yes"

BOOTPROTO="none"

#eno16777736 MAC

HWADDR=bc:ee:7b:78:7b:a7

IPADDR=172.16.209.10

GATEWAY=172.16.209.1

NETMASK=255.255.255.0

DNS1=202.106.0.20

DNS1=8.8.8.8

NM_CONTROLLED=no #表示修改配置文件後不當即生效，而是在重啓/重載network服務時生效

systemctl restart network

ovs-vsctl add-port br-ex eth0

三：計算節點配置

1. 編輯 /etc/sysctl.conf

net.ipv4.conf.all.rp_filter=0

net.ipv4.conf.default.rp_filter=0

net.bridge.bridge-nf-call-iptables=1

net.bridge.bridge-nf-call-ip6tables=1

2.sysctl -p

3.yum install openstack-neutron openstack-neutron-ml2 openstack-neutron-openvswitch -y

4.編輯 /etc/neutron/neutron.conf文件

[DEFAULT]

rpc_backend = rabbit

auth_strategy = keystone

[oslo_messaging_rabbit]

rabbit_host = controller01

rabbit_userid = openstack

rabbit_password = che001

[oslo_concurrency]

lock_path = /var/lib/neutron/tmp

5．編輯 /etc/neutron/plugins/ml2/openvswitch_agent.ini

[ovs]

#下面ip爲計算節點數據網絡ip

local_ip = 1.1.1.117

#bridge_mappings = vlan:br-vlan

[agent]

tunnel_types = gre,vxlan

l2_population = True

prevent_arp_spoofing = True

[securitygroup]

firewall_driver = neutron.agent.linux.iptables_firewall.OVSHybridIptablesFirewallDriver

enable_security_group = True

7.編輯 /etc/nova/nova.conf

[neutron]

url = http://controller01:9696

auth_url = http://controller01:5000

auth_type = password

project_domain_name = default

user_domain_name = default

region_name = RegionOne

project_name = service

username = neutron

password = che001

8．啓動服務

systemctl enable neutron-openvswitch-agent.service

systemctl start neutron-openvswitch-agent.service

systemctl restart openstack-nova-compute.service

part6:部署控制面板dashboard

在控制節點

1.安裝軟件包

yum install openstack-dashboard -y

2.配置/etc/openstack-dashboard/local_settings

OPENSTACK_HOST = "controller01"

ALLOWED_HOSTS = ['*', ]

SESSION_ENGINE = 'django.contrib.sessions.backends.cache'

CACHES = {

'default': {

'BACKEND': 'django.core.cache.backends.memcached.MemcachedCache',

'LOCATION': 'controller01:11211',

}

OPENSTACK_KEYSTONE_URL = "http://%s:5000/v3" % OPENSTACK_HOST

OPENSTACK_KEYSTONE_MULTIDOMAIN_SUPPORT = True

OPENSTACK_API_VERSIONS = {

"identity": 3,

"image": 2,

"volume": 2,

}

OPENSTACK_KEYSTONE_DEFAULT_DOMAIN = "default"

OPENSTACK_KEYSTONE_DEFAULT_ROLE = "user"

TIME_ZONE = "UTC"

3.啓動服務

systemctl enable httpd.service memcached.service

systemctl restart httpd.service memcached.service

4.驗證；

http://172.16.209.115/dashboard

總結：

與keystone打交道的只有api層，因此不要處處亂配
建主機的時候由nova-compute負責調用各個api，因此不要再控制節點配置啥調用
ml2是neutron的core plugin，只須要在控制節點配置
網絡節點只須要配置相關的agent
各組件的api除了接收請求外還有不少其餘功能，比方說驗證請求的合理性，控制節點nova.conf須要配neutron的api、認證，由於nova boot時須要去驗證用戶提交網絡的合理性，控制節點neutron.conf須要配nova的api、認證，由於你刪除網絡端口時須要經過nova-api去查是否有主機正在使用端口。計算幾點nova.conf須要配neutron，由於nova-compute發送請求給neutron-server來建立端口。這裏的端口值得是'交換機上的端口'
不明白爲啥？或者不懂我在說什麼，請好好研究openstack各組件通訊機制和主機建立流程，或者來聽個人課哦，通常博文都不教真的。
