简介

本文档旨在帮助那些想要在Ubuntu 12.04 LTS(使用Ubuntu Cloud Archive)上部署OpenStack Folsom用于开发目的的人。我们将安装三个节点:一个控制器节点,一个网络节点和一个计算节点。当然,你可以根据需要安装更多的节点。对于那些想要安装测试基础设施的OpenStack新手来说,本文档是个好起点。

体系结构

Newton centos7 openstack 安装 如何安装openstack_重启


标准Quantum部署包括多达4个不同的物理数据中心网络:

  • 管理网络。用于OpenStack组件之间的内部通信。网络的IP地址只应该在数据中心内部可达。
  • 数据网络。用于在云部署内部虚拟机之间数据通信。网络的IP地址的编址需求依赖于使用的Quantum插件。
  • 外部网络。某些场景下,用于提供虚拟机的Internet访问。网络的IP地址应该对Internet上的任何主机可达。
  • API网络:暴露所有的OpenStackAPIs给租户,包括Quantum API。网络的IP地址应该对Internet的所有主机可达。这可能和外部网络是同一个网络,因为可以为外部网络创建一个Quantum子网,通过IP分配范围只使用整个IP块全部地址范围的一部分IP地址。

需求

至少需要三台机器(虚拟或物理)并安装了Ubuntu 12.04(LTS)。

操作系统

1.      安装Ubuntu,安装时设置如下参数:

  • 时区:UTC
  • 主机名:contoller
  • 软件包:OpenSSH-Server

操作系统安装完成后,重启服务器。

2.      由于Ubuntu 12.04 LTS默认包含OpenStack Essex,我们将使用Ubuntu Cloud Archive获取Folsom:

apt-get install ubuntu-cloud-keyring

 

编辑/etc/apt/sources.list.d/cloud-archive.list:

deb http://ubuntu-cloud.archive.canonical.com/ubuntu precise-updates/folsom main

 

升级系统(需要的话重启):

apt-get update && apt-get upgrade

3.      配置网络:

Ÿ   编辑/etc/network/interfaces文件:

# Management Network
auto eth0
iface eth0 inet static
address 192.168.0.1
netmask 255.255.255.0
# API + Public Network
auto eth1
iface eth1 inet static
address 7.7.7.7
netmask 255.255.255.0

dns-nameservers 8.8.8.8

 

Ÿ   编辑/etc/sysctl.conf

net.ipv4.conf.all.rp_filter = 0
net.ipv4.conf.default.rp_filter = 0

 

然后重启网络服务:

service networking restart

 

Ÿ   编辑/etc/hosts文件,添加主机名controller,network和compute1及相应IP。

127.0.0.1       localhost
127.0.1.1       controller
192.168.0.1     controller

2.      允许从网络连接数据库:

sed -i 's/127.0.0.1/0.0.0.0/g' /etc/mysql/my.cnf

 

3.      重启服务:

service mysql restart

 

4.      创建数据库,用户和权限:

mysql -u root -ppassword <<EOF
CREATE DATABASE nova;
GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'localhost' \
IDENTIFIED BY 'password';
GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'192.168.0.1' \

RabbitMQ消息服务

1.      安装软件包:

apt-get install rabbitmq-server

 

2.      修改默认口令:

rabbitmqctl change_password guest password

 

Keystone

1.      安装软件包:

apt-get install keystone python-keystone python-keystoneclient

 

2.      编辑/etc/keystone/keystone.conf:

[DEFAULT]
admin_token = password
bind_host = 0.0.0.0
public_port = 5000
admin_port = 35357
compute_port = 8774
verbose = True
debug = True
log_file = keystone.log
log_dir = /var/log/keystone
log_config = /etc/keystone/logging.conf
[sql]
connection = mysql://keystone:password@localhost:3306/keystone
idle_timeout = 200
[identity]
driver = keystone.identity.backends.sql.Identity
[catalog]
driver = keystone.catalog.backends.sql.Catalog
(...)

 

 

3.      重启Keystone并在数据库创建表:

service keystone restart
keystone-manage db_sync

 

4.      加载环境变量:

Ÿ   创建novarc文件:

export OS_TENANT_NAME=admin
export OS_USERNAME=admin
export OS_PASSWORD=password
export OS_AUTH_URL="http://localhost:5000/v2.0/"
export SERVICE_ENDPOINT="http://localhost:35357/v2.0"
export SERVICE_TOKEN=password

Ÿ   导出环境变量:

source novarc
echo "source novarc">>.bashrc

 

5.      下载数据脚本,并用数据(用户、租户、服务)填充Keystone数据库:

./keystone-data.sh

 

6.      下载endpoint脚本,并创建endpoints(为项目):

./keystone-endpoints.sh

如果管理器节点上的管理网络的IP地址与此例不同,请使用如下命令:

./keystone-endpoints.sh -K <ip address of the management network>

 

Glance

Ÿ   在数据库中创建Glance数据表:

glance-manage db_sync

 

Ÿ   下载并导入Ubuntu12.04 LTS UEC镜像:

glance image-create \
--location http://uec-images.ubuntu.com/releases/12.04/release/ubuntu-12.04-server-cloudimg-amd64-disk1.img \
--is-public true --disk-format qcow2 --container-format bare --name "Ubuntu"

 

Ÿ   检查镜像是否已在索引中引入:

glance image-list
+--------------------------------------+--------+-------------+------------------+-----------+--------+
| ID                                   | Name   | Disk Format | Container Format | Size      | Status |

  • 重启Nova服务:
service nova-compute restart

 

Quantum

Open vSwitch

1.      安装软件包:

apt-get install -y openvswitch-switch

 

2.      启动Open vSwitch服务:

 

service openvswitch-switch start

 

3.      配置虚拟网桥:

ovs-vsctl add-br br-int

 

Quantum

1.      安装软件包:

 

apt-get install -y quantum-plugin-openvswitch-agent

 

 

2.      编辑/etc/quantum/quantum.conf文件并修改:

core_plugin = \
quantum.plugins.openvswitch.ovs_quantum_plugin.OVSQuantumPluginV2
auth_strategy = keystone
fake_rabbit = False
rabbit_host = 192.168.0.1
rabbit_password = password

 

3.      编辑/etc/quantum/plugins/openvswitch/ovs_quantum_plugin.ini文件并修改:

[DATABASE]
sql_connection = mysql://quantum:password@192.168.0.1:3306/quantum
[OVS]
tenant_network_type = gre
tunnel_id_ranges = 1:1000
integration_bridge = br-int
tunnel_bridge = br-tun
local_ip = 10.10.10.2
enable_tunneling = True

 

4.      启动Agent:

service quantum-plugin-openvswitch-agent restart

 

创建第一个虚拟机

1.      现在你可以使用OpenStack API或Dashboard通过demo/password来管理你自己的IaaS:http://192.168.0.1/horizon。

2.      修改安全组”Default”以允许ICMP和SSH。

3.      创建个人的keypair。

4.      在Dashboard中,去”Instances”点击“Launch Instance”生成一个新的虚拟机。

5.      由于Horizon在Folsom发布中不管理L3,因此我们需要从Quantum CLI(使用默认demo租户)配置浮动IP。为了做这一步,你需要得到ext_net ID和虚拟机的port_id:

quantum net-list -- --router:external True
quantum port-list -- --device_id <vm-uuid>

 

6.      现在,我们将创建一个绑定到我们虚拟机的虚端口的浮动IP,并路由到外部网络:

quantum floatingip-create --port_id <port_id> <ext_net_id>

 

7.      就是这样了。你应该能够通过浮动IP ping通你的虚拟机。

总结

我们已经为高级测试创建了基本架构。这种架构和生产环境类似,但没有高可用(HA)和一些服务,如运行OpenStack Object Storage。你当然可以按照需要添加更多的计算节点。如果你需要更多的帮助,请阅读每个项目的官方文档或往OpenStack邮件列表中发邮件。
