節點規劃
準備4臺虛機，分別做Controller,Network,Compute,Middleware。
Controller安裝keystone,glance,nova-api,nova-conductor,nova-scheduler,nova-placement
Network安裝neutron相關元件
Compute安裝nova-compute
Middleware安裝mariadb,rabbitmq,memcache。
網路規劃
controller
eth0: 192.168.100.111 external
eth1: 10.1.1.1 admim
network
eth0: 192.168.100.114 external
eth1: 10.1.1.4 admin
eth2: 10.2.2.4 tunnel
compute
eth0: 192.168.100.112 external
eth1: 10.1.1.2 admin
eth2: 10.2.2.2 tunnel
middleware (mysql,mq,memcache)
eth1: 10.1.1.3 admin
基礎配置
每個節點都按如下操作
hosts檔案
echo "
10.1.1.1 controller
10.1.1.2 compute
10.1.1.3 middleware
10.1.1.4 network
" >>/etc/hosts
配置yum源
yum install -y wget
wget -O /etc/yum.repos.d/CentOS-Base.repo
yum install centos-release-openstack-pike -y
yum clean all && yum makecache
時間同步
echo "*/3 * * * * /usr/sbin/ntpdate ntp6.aliyun.com &> /dev/null" > /tmp/crontab
crontab /tmp/crontab
Middleware節點
安裝資料庫

給openstack使用者賦予許可權
rabbitmqctl set_permissions openstack ".*" ".*" ".*"
rabbitmqctl set_user_tags openstack administrator
rabbitmqctl list_users
開啟RabbitMQ相關外掛
/usr/lib/rabbitmq/bin/rabbitmq-plugins enable rabbitmq_management mochiweb webmachine rabbitmq_web_dispatch amqp_client rabbitmq_management_agent
檢視RabbitMQ外掛
/usr/lib/rabbitmq/bin/rabbitmq-plugins list

yum install -y memcached python-memcached
配置memcache監聽埠
sed -i 's/OPTIONS*.*/OPTIONS="-l 127.0.0.1,10.1.1.3"/' /etc/sysconfig/memcached
重啟memcache並設定開機啟動
systemctl restart memcached.service
systemctl enable memcached.service
systemctl status memcached.service

Controller節點

建立flat模式的public網路，public是外出網路，必須是flat模式的
neutron net-create --shared provider --router:external True --provider:network_type flat --provider:physical_network provider
本實驗環境192.168.100.0/24網段可以出外網，就以該網段作為public網段
建立子網
neutron subnet-create provider 192.168.100.0/24 --name provider-sub --allocation-pool start=192.168.100.180,end=192.168.100.190 --dns-nameserver 8.8.8.8 --gateway 192.168.100.180
建立名為private的私有網路, 網路模式為vxlan
neutron net-create private --provider:network_type vxlan --router:external False --shared
建立名為private-subnet的私有網路子網，網段為172.17.1.0, 這個網段就是虛擬機器獲取的私有的IP地址
neutron subnet-create private --name private-subnet --gateway 172.17.1.1 172.17.1.0/24
也可以建立多個不同的私有子網路
如果虛機要能夠訪問外部網路還需要新增路由
新增路由
neutron router-create router01
將私有網路的子網加入路由
neutron router-interface-add router01 private-sub
設定public網路為路由的閘道器
neutron router-gateway-set router01 provider

Compute節點搭建完畢，執行nova host-list可以檢視新加入的compute節點
如果需要再新增另外一個compute節點，只要重複下Compute節點部部分即可，計算機名和IP地址改下
