Ubuntu11.04环境下Openstack云平台构建

===Ubuntu11.04环境下Openstack云平台构建====

本次实验包含两个主要部分：NovaCC和Nova-compute
环境信息:
NovaCC:
Public:192.168.0.110/24
Private:192.168.3.1/24

Nova-compute:
Public:192.168.0.111/24
Private:192.168.3.2/24

#####Nova-CC安装和配置######
一、基本准备工作
1.重置root密码
2.设置本地网络可以上网，并且设置/etc/apt/source.list可以进行apt-get更新
3.安装ssh，方便使用secureCRT工具进行远程连接控制
4.执行#apt-get update和#apt-get dist-upgrade更新源包信息和包升级
5.安装桥接#apt-get install -y bridge-utils
6.配置本地网络信息和桥接:
 
auto lo 
iface lo inet loopback 
auto eth0 
iface eth0 inet static 
address 192.168.0.110
netmask 255.255.255.0 
broadcast 10.10.10.255 
gateway 192.168.0.2 
dns-nameservers 192.168.0.2

auto br100 
iface br100 inet static 
bridge_ports eth1 
bridge_stp off 
bridge_maxwait 0 
bridge_fd 0 
address 192.168.3.1

//**
把novacc节点上的配置文件复制过来，
scp 192.168.0.110:/etc/nova/nova.conf /etc/nova/nova.conf
进行修改:
添加一个选项,   --flat_interface=eth0/eth1???
**//
二、nova components configure
1.sudo apt-get install -y nova-common python-nova nova-compute vlan
2.sudo apt-get install -y euca2ools
3.sudo apt-get install -y unzip

finished!

以上是NovaCC和Nova-compute的配置，但是没有
============================================================

以下配置是在NovaCC上的Dashboard配置（未完成）

1.创建目录
#apt-get install -y bzr
#bzr init-repo .
#bzr branch lp:openstack-dashboard /opt/osdb
#cd /opt/osdb/
###sh run_test.sh###  //暂时省略
#bzr revert -r 46

2.安装配置dashboard
#cd /opt/osdb/openstack-dashboard/local
#cp local_settings.py.example local_settings.py
#vi local_settings.py

编辑/opt/osdb/openstack-dashboard/local/local_settings.py

//****local_settings.py

import os

DEBUG = True
TEMPLATE_DEBUG = DEBUG
PROD = False
USE_SSL = False

LOCAL_PATH = os.path.dirname(os.path.abspath(__file__))
DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.sqlite3',
        'NAME': os.path.join(LOCAL_PATH, 'dashboard_openstack.sqlite3'),
    },
}

CACHE_BACKEND = 'dummy://'

# Configure these for your outgoing email host
# EMAIL_HOST = 'smtp.my-company.com'
# EMAIL_PORT = 25
# EMAIL_HOST_USER = 'djangomail'
# EMAIL_HOST_PASSWORD = 'top-secret!'

NOVA_DEFAULT_ENDPOINT = 'http://localhost:8773/services/Cloud'
NOVA_DEFAULT_REGION = 'nova'
NOVA_ACCESS_KEY = 'admin'
NOVA_SECRET_KEY = 'admin'
NOVA_ADMIN_USER = 'novaadmin'
NOVA_PROJECT = 'proj'

# Configure these for your outgoing email host
# EMAIL_HOST = 'smtp.my-company.com'
# EMAIL_PORT = 25
## EMAIL_HOST_USER = 'djangomail'
## EMAIL_HOST_PASSWORD = 'top-secret!'

//***结束

3.配置dashboard环境
#apt-get install -y python-setuptools
#cd ..  //这个位置应该是/opt/osdb/openstack-dashboard/目录
#sudo easy_install virtualenv
#python tools/install_venv.py

4.创建数据库
# tools/with_venv.sh dashboard/manage.py syncdb
//在此输入的用户名和密码总提示错误。

While creating the schema, the above command asks you to create an admin account for the dashboard. Choose the user name as the project admin’s user name you chose above while creating the project ( novadmin in our case). You can choose any password you like.

# tools/with_venv.sh dashboard/manage.py runserver 10.10.10.2:8000  //这个是可以进行访问的，但是属于手工操作
