1.需求

節點角色　　 NICs
控制節點　　 eth0(10.10.10.51)eth1(192.168.100.51)
網絡節點　　　　　　 eth0(10.10.10.52)eth1(10.20.20.52)eth2(192.168.100.52)
計算結點 eth0(10.10.10.53)eth1(10.20.20.53)

 

 

 

 

注意1：你老是可使用dpkg -s <packagename>確認你是用的是Havana版本html

注意2：這個是當前網絡架構node

2.控制節點

2.1.準備Ubuntu

  • 安裝好Ubuntu12.04 server 64bits後，進入root模式進行安裝。python

sudo su -
  • 添加Havana倉庫：
#apt-get install python-software-properties
#add-apt-repository cloud-archive:havana
  • 升級系統：
#apt-get update
#apt-get upgrade
#apt-get dist-upgrade
 
2.2設置網絡

  • 配置網卡編輯/etc/network/interfaces:mysql

複製代碼 
#For Exposing OpenStack API over the internet
auto eth1
iface eth1 inet static
address 192.168.100.51
netmask 255.255.255.0
gateway 192.168.100.1
dns-nameservers 8.8.8.8

#Not internet connected(used for OpenStack management)
auto eth0
iface eth0 inet static
address 10.10.10.52
netmask 255.255.255.0
複製代碼
  • 重啓網絡服務
#/etc/init.d/networking restart

  • 開啓路由轉發：linux

 
sed -i 's/#net.ipv4.ip_forward=1/net.ipv4.ip_forward=1/' /etc/sysctl.conf
sysctl -p
 
2.3安裝MySQL
  • 安裝MySQL併爲root用戶設置密碼：
#apt-get install mysql-server python-mysqldb
  • 配置mysql監聽全部網絡請求
#sed -i 's/127.0.0.1/0.0.0.0/g' /etc/mysql/my.cnf
#service mysql restart

2.4安裝RabbitMQ和NTPgit

  • 安裝RabbitMQ:
#apt-get install rabbitmq-server
  • 安裝NTP服務
#apt-get install ntp
2.5建立數據庫
  •  建立數據庫
複製代碼 
#mysql -u root -p

#Keystone
CREATE DATABASE keystone;
GRANT ALL ON keystone.* TO 'keystoneUser'@'%' IDENTIFIED BY 'keystonePass';
#Glance
CREATE DATABASE glance;
GRANT ALL ON glance.* TO 'glanceUser'@'%' IDENTIFIED BY 'glancePass';
#Neutron
CREATE DATABASE neutron;
GRANT ALL ON neutron.* TO 'neutronUser'@'%' IDENTIFIED BY 'neutronPass';
#Nova
CREATE DATABASE nova;
GRANT ALL ON nova.* TO 'novaUser'@'%' IDENTIFIED BY 'novaPass';
#Cinder
CREATE DATABASE cinder;
GRANT ALL ON cinder.* TO 'cinderUser'@'%' IDENTIFIED BY 'cinderPass';
#Swift
CREATE DATABASE swift;
GRANT ALL ON swift.* TO 'swiftUser'@'%' IDENTIFIED BY 'swiftPass';

quit;
複製代碼

2.6.配置Keystonegithub

  • 安裝keystone軟件包：ajax

apt-get install keystone

  • 在/etc/keystone/keystone.conf中設置鏈接到新建立的數據庫：sql

connection=mysql://keystone:keystonePass@10.10.10.51/keystone

  • 重啓身份認證服務並同步數據庫：mongodb

service keystone restart
keystone-manage db_dync

  • 接下來同步數據庫：
cinder-manage db sync
  • 最後別忘記建立一個卷組命名爲cinder-volumes:
複製代碼 
dd if=/dev/zero of=cinder-volumes bs=1 count=0 seek=2G
losetup /dev/loop2 cinder-volumes
fdisk /dev/loop2
#Type in the followings:
n
p
1
ENTER
ENTER
t
8e
w
複製代碼
  • 建立物理卷和卷組：
pvcreate /dev/loop2
vgcreate cinder-volumes /dev/loop2
  • 注意：重啓後卷組不會自動掛載，以下進行設置：
vim /etc/init/losetup.conf

description "set up loop devices"
start on mounted MOUNTPOINT=/
task
exec /sbin/losetup  /dev/loop2 /home/cloud/cinder-volumes
  • 重啓cinder服務：
cd /etc/init.d/; for i in $( ls cinder-* ); do service $i restart; done
  • 確認Cinder服務在運行：
cd /etc/init.d/; for i in $( ls cinder-* ); do service $i status; done
2.11.設置Horizon
  • 安裝horizon：
apt-get install openstack-dashboard memcached
  • 若是你不喜歡OpenStack ubuntu主題，你能夠停用它：
dpkg --purge openstack-dashboard-ubuntu-theme
  • 重啓Apache和memcached服務：
service apache2 restart; service memcached restart

注意：重啓apache2,出現could not reliably determine the server's fully domain name,using 127.0.0.1 for ServerName.這是因爲沒有解析出域名致使的。解決方法以下：編輯/etc/apache2/apache2.conf，添加以下操做便可。

ServerName localhost

2.12.設置Ceilometer

  • 安裝Metering服務
apt-get install ceilometer-api ceilometer-collector ceilometer-agent-central python-ceilometerclient
  • 安裝MongoDB數據庫
apt-get install mongodb
  • 配置mongodb監聽全部網絡接口請求：
sed -i 's/127.0.0.1/0.0.0.0/g' /etc/mongodb.conf

service mongodb restart
  • 建立ceilometer數據庫用戶：
#mongo
>use ceilometer
>db.addUser({ user:"ceilometer",pwd:"CEILOMETER_DBPASS",roles:["readWrite","dbAdmin"]})
  • 配置Metering服務使用數據庫
複製代碼 
...
[database]
...

# database (string value)
connection = mongodb://ceilometer:CEILOMETER_DBPASS@10.10.10.51:27017/ceilometer
...
複製代碼
  • 配置RabbitMQ訪問,編輯/etc/ceilometer/ceilometer.conf
...

rabbit_host = 10.10.10.51
  • 編輯/etc/ceilometer/ceilometer.conf使認證信息生效
複製代碼

admin_password = CEILOMETER_PASS
複製代碼
  • 簡單獲取鏡像，你必須配置鏡像服務以發送通知給總線，編輯/etc/glance/glance-api.conf修改[DEFAULT]部分
notifier_strategy=rabbit
rabbit_host=10.10.10.51
  • 重啓鏡像服務
cd /etc/init.d/;for i in $(ls glance-* );do service $i restart;done
  • 重啓服務，使配置信息生效
cd /etc/init.d;for i in $( ls ceilometer-* );do service $i restart;done
  • 編輯/etc/cinder/cinder.conf，獲取volume。
control_exchange=cinder
notification_driver=cinder.openstack.common.notifier.rpc_notifier
  • 重啓Cinder服務

3.網絡結點

  • 安裝好ubuntu 12.04 Server 64bits後，進入root模式下完成配置：

sudo su -
  • 添加Havana源：
#apt-get install python-software-properties
#add-apt-repository cloud-archive:havana

  • 升級系統：

  • apt-get update
apt-get upgrade
apt-get dist-upgrade
  • 安裝ntp服務：
apt-get install ntp
  • 配置ntp服務從控制節點上同步時間：
複製代碼 
sed -i 's/server 0.ubuntu.pool.ntp.org/#server 0.ubuntu.pool.ntp.org/g' /etc/ntp.conf
sed -i 's/server 1.ubuntu.pool.ntp.org/#server 1.ubuntu.pool.ntp.org/g' /etc/ntp.conf
sed -i 's/server 2.ubuntu.pool.ntp.org/#server 2.ubuntu.pool.ntp.org/g' /etc/ntp.conf

6.參考文檔：

1.openstack官方文檔：http://docs.openstack.org/havana/install-guide/install/apt/openstack-install-guide-apt-havana.pdf  目前openstack官方文檔已經作的很好了，如何安裝，配置，寫的都挺不錯的，還有neutron那一節對各類狀況的網絡結構列出的很詳細。

2.感謝Bilel Msekni作出的貢獻，https://github.com/mseknibilel/OpenStack-Grizzly-Install-Guide/blob/OVS_MultiNode/OpenStack_Grizzly_Install_Guide.rst
