Ubuntu 12.04 Server OpenStack Havana多节点(OVS+GRE)安装

1.需求

节点角色	NICs
控制节点	eth0(10.10.10.51)eth1(192.168.100.51)
网络节点	eth0(10.10.10.52)eth1(10.20.20.52)eth2(192.168.100.52)
计算结点	eth0(10.10.10.53)eth1(10.20.20.53)

注意1：你总是可以使用dpkg -s <packagename>确认你是用的是Havana版本

注意2：这个是当前网络架构

2.控制节点

2.1.准备Ubuntu

安装好Ubuntu12.04 server 64bits后，进入root模式进行安装。

sudo su -

添加Havana仓库：

#apt-get install python-software-properties
#add-apt-repository cloud-archive:havana

升级系统：

#apt-get update
#apt-get upgrade
#apt-get dist-upgrade

2.2设置网络

配置网卡编辑/etc/network/interfaces:

#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 10.10.10.2
netmask 255.255.255.0

重启网络服务

#/etc/init.d/networking restart

开启路由转发：

sed -i 's/#net.ipv4.ip_forward=1/net.ipv4.ip_forward=1/' /etc/sysctl.conf
sysctl -p

2.3安装MySQL

安装MySQL并为root用户设置密码：

#apt-get install mysql-server python-mysqldb

配置mysql监听所有网络请求

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

2.4安装RabbitMQ和NTP

安装RabbitMQ:

#apt-get install rabbitmq-server

安装NTP服务

#apt-get install ntp

2.5创建数据库

创建数据库

#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';
#Quantum
CREATE DATABASE neutron;
GRANT ALL ON quantum.* 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;

2.6.配置Keystone

安装keystone软件包：

apt-get install keystone

在/etc/keystone/keystone.conf中设置连接到新创建的数据库：

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

重启身份认证服务并同步数据库：

service keystone restart
keystone-manage db_dync

    按 Ctrl+C 复制代码
   
    按 Ctrl+C 复制代码

上述脚本文件为了填充keystone数据库，其中还有些内容根据自身情况修改。
创建一个简单的凭据文件，这样稍后不会因为输入过多的环境变量而感到厌烦。
通过命令列出keystone中添加的用户以及得到token：

keystone user-list
keystone token-get

2.7.设置Glance

安装Glance

apt-get install glance

更新/etc/glance/glance-api-paste.ini

[filter:authtoken]
paste.filter_factory = keystoneclient.middleware.auth_token:filter_factory

flavor = keystone

更新/etc/glance/glance-registry.conf

sql_connection = mysql://glanceUser:glancePass@10.10.10.51/glance
和
[paste_deploy]
flavor = keystone

重新启动glance服务：

cd /etc/init.d/;for i in $( ls glance-* );do service $i restart;done

同步glance数据库

cd /etc/init.d/;for i in $( ls glance-* );do service $i restart;done

测试Glance

mkdir images
cd images
wget http://cdn.download.cirros-cloud.net/0.3.1/cirros-0.3.1-x86_64-disk.iimg
glance image-create --name="Cirros 0.3.1" --disk-format=qcow2 --container-format=bare --is-public=true <cirros-0.3.1-x86_64-disk.img

列出镜像检查是否上传成功：

glance image-list

2.8.设置Neutron

安装Neutron组件：

apt-get install neutron-server

编辑/etc/neutron/api-paste.ini

[filter:authtoken]

# Compute #
compute_driver=libvirt.LibvirtDriver

# Cinder #
volume_api_class=nova.volume.cinder.API
osapi_volume_listen_port=5900

同步数据库：

nova-manage db sync

重启Nova所有服务：

cd /etc/init.d/; for i in $( ls nova-* ); do  service $i restart; done

检查所有nova服务是否启动正常：

nova-manage service list

2.10.设置Cinder

安装Cinder软件包

apt-get install  cinder-api cinder-scheduler cinder-volume iscsitarget open-iscsi iscsitarget-dkms

配置iscsi服务：

sed -i 's/false/true/g' /etc/default/iscsitarget

重启服务：

service iscsitarget start
service open-iscsi start

配置/etc/cinder/api-paste.ini

filter:authtoken]
paste.filter_factory = keystoneclient.middleware.auth_token:filter_factory
service_protocol = http
service_host = 192.168.0.51
service_port = 5000
auth_host = 10.10.10.51
auth_port = 35357
auth_protocol = http
admin_tenant_name = service
admin_user = cinder
admin_password = service_pass

编辑/etc/cinder/cinder.conf

[DEFAULT]
rootwrap_config=/etc/cinder/rootwrap.conf
sql_connection = mysql://cinderUser:cinderPass@10.10.10.51/cinder
api_paste_config = /etc/cinder/api-paste.ini
iscsi_helper=ietadm
volume_name_template = volume-%s
volume_group = cinder-volumes
verbose = True
auth_strategy = keystone
#osapi_volume_listen_port=5900

接下来同步数据库：

cinder-manage db sync

最后别忘记创建一个卷组命名为cinder-volumes:

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

创建物理卷和卷组：

pvcreate /dev/loop2
vgcreate cinder-volumes /dev/loop2

注意：重启后卷组不会自动挂载，如下进行设置：

vim /etc/init/losetup.conf

description "set up loop devices"
start on mounted MOUNTPOINT=/
task
exec /sbin/losetup  /dev/loop0 /dev/cinder-volumes

重启cinder服务：

cd /etc/init.d/; for i in $( ls cinder-* ); do service $i restart; done

确认Cinder服务在运行：

cd /etc/init.d/; for i in $( ls cinder-* ); do service $i status; done

2.11.设置Horizon

安装horizon：

apt-get install openstack-dashboard memcached

如果你不喜欢OpenStack ubuntu主题，你可以停用它：

dpkg --purge openstack-dashboard-ubuntu-theme

重启Apache和memcached服务：

service apache2 restart; service memcached restart

注意：重启apache2,出现could not reliably determine the server's fully domain name,using 127.0.0.1 for ServerName.这是由于没有解析出域名导致的。解决方法如下：编辑/etc/apache2/httpd.conf，添加如下操作即可。

ServerName localhost

2.12.设置Ceilometer

安装Metering服务

apt-get install ceilometer-api ceilometer-collector ceilometer-agent-central python-ceilometerclient

安装MongoDB数据库

apt-get install mongodb

配置mongodb监听所有网络接口请求：

sed -i 's/127.0.0.1/0.0.0.0/g' /etc/mongodb.conf

service mongodb restart

创建ceilometer数据库用户：

#mongo
>use ceilometer
>db.addUser({ user:"ceilometer",pwd:"CEILOMETER_DBPASS",roles:["readWrite","dbAdmin"]})

配置Metering服务使用数据库

...
[database]
...
# The SQLAlchemy connection string used to connect to the
# database (string value)
connection = mongodb://ceilometer:CEILOMETER_DBPASS@10.10.10.51:27017/ceilometer
...

配置RabbitMQ访问,编辑/etc/ceilometer/ceilometer.conf

...
[DEFAULT]
rabbit_host = 10.10.10.51

编辑/etc/ceilometer/ceilometer.conf使认证信息生效

[keystone_authtoken]
auth_host = 10.10.10.51
auth_port = 35357
auth_protocol = http
admin_tenant_name = service
admin_user = ceilometer
admin_password = CEILOMETER_PASS

简单获取镜像，你必须配置镜像服务以发送通知给总线，编辑/etc/glance/glance-api.conf修改[DEFAULT]部分

notifier_strategy=rabbit
rabbit_host=10.10.10.51

重启镜像服务

cd /etc/init.d/;for i in $(ls glance-* );do service $i restart;done

重启服务，使配置信息生效

cd /etc/init.d;for i in $( ls ceilometer-* );do service $i restart;done

编辑/etc/cinder/cinder.conf，获取volume。

control_exchange=cinder
notification_driver=cinder.openstack.common.notifier.rpc_notifier

重启Cinder服务

cd /etc/init.d/;for i in $( ls cinder-* );do service $i restart;done

3.网络结点

安装好ubuntu 12.04 Server 64bits后，进入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

升级系统：

apt-get update
apt-get upgrade
apt-get dist-upgrade

安装ntp服务：

apt-get install ntp

配置ntp服务从控制节点上同步时间：

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
sed -i 's/server 3.ubuntu.pool.ntp.org/#server 3.ubuntu.pool.ntp.org/g' /etc/ntp.conf

#Set the network node to follow up your conroller node
sed -i 's/server ntp.ubuntu.com/server 10.10.10.51/g' /etc/ntp.conf

service ntp restart

配置网络：

# OpenStack management
auto eth0
iface eth0 inet static
address 10.10.10.52
netmask 255.255.255.0

# VM Configuration
auto eth1

netmask 255.255.255.0
gateway 192.168.100.1
dns-servers 8.8.8.8

编辑/etc/sysctl.conf,开启路由转发和关闭包目的过滤，这样网络节点能协作VMs的traffic。

net.ipv4.ip_forward=1
net.ipv4.conf.all.rp_filter=0
net.ipv4.conf.default.rp_filter=0

#运行下面命令，使生效
sysctl -p

3.3.安装OpenVSwitch

安装OpenVSwitch软件包：

#br-ex is used to make to VM accessable from the internet
ovs-vsctl add-br br-ex

把网卡eth2加入br-ex：

ovs-vsctl add-port br-ex eth2

重新修改网卡配置/etc/network/interfaces:

# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

# The loopback network interface
auto lo
iface lo inet loopback

# Not internet connected(used for OpenStack management)
# The primary network interface

重启服务：

service quantum-plugin-openvswitch-agent restart

注意：如果你的宿主机不支持kvm虚拟化，可把nova-compute-kvm换成nova-compute-qemu
同时/etc/nova/nova-compute.conf配置文件中的libvirt_type=qemu

4.6.Nova

安装nova组件：

apt-get install nova-compute-kvm python-guestfs

在/etc/nova/api-paste.ini配置文件中修改认证信息：

[filter:authtoken]
paste.filter_factory = keystoneclient.middleware.auth_token:filter_factory
auth_host = 10.10.10.51
auth_port = 35357
auth_protocol = http
admin_tenant_name = service
admin_user = nova
admin_password = service_pass
signing_dirname = /tmp/keystone-signing-nova
# Workaround for https://bugs.launchpad.net/nova/+bug/1154809
auth_version = v2.0

编辑修改/etc/nova/nova.conf

重启nova-*服务：

cd /etc/init.d/; for i in $( ls nova-* ); do service $i restart; done

检查所有nova服务是否正常启动：

nova-manage service list

4.7. 为监控服务安装计算代理

安装监控服务：

ap-get install ceilometer-agent-compute

配置修改/etc/nova/nova.conf:

...
[DEFAULT]
...
instance_usage_audit=True
instance_usage_audit_period=hour
notify_on_state_change=vm_and_task_state
notification_driver=nova.openstack.common.notifier.rpc_notifier
notification_driver=ceilometer.compute.nova_notifier

重启服务：

service ceilometer-agent-compute restart

5.创建第一VM

5.1.为admin租户创建内网、外网、路由器和虚拟机

设置环境变量：

vim creds-admin

#Paste the following:
export OS_TENANT_NAME=admin
export OS_USERNAME=admin
export OS_PASSWORD=admin_pass
export OS_AUTH_URL="http://192.168.100.51:5000/v2.0/"

source creds-admin

列出已创建的用户和租户：

keystone user-list
keystone tenant-list

为admin租户创建网络：

neutron net-create --tenant-id $id_of_tenant --router:external=True net_admin

为admin租户创建子网：

neutron subnet-create --tenant-id $id_of_tenant net_admin 50.50.50.0/24

为admin租户创建路由器：

neutron router-create --tenant-id $id_of_tenant router_admin

列出路由代理类型：

neutron agent-list

将router_admin设置为L3代理类型：

neutron l3-agent-router-add $id_of_l3_agent router_admin

Added router router_admin to L3 agent

将net_admin子网与router_admin路由关联：

neutron router-interface-add $id_of_router_admin $id_of_net_admin

创建外网net_external，注意设置--router:external=True：

neutron net-create net_external --router:external=True --shared

为net_admin创建子网，注意设置的gateway必须在给到的网段内：

neutron subnet-create --tenant-id $id_of_tenant --allocation-pool start=192.168.100.102,end=192.168.100.130 --gateway=192.168.100.1 net_external 192.168.100.0/24 --enable_dhcp=False

将net_external与router_admin路由器关联：

neutron router-gateway-set router_admin net_external

Set gateway for router router_admin

创建floating ip:

neutron floatingip-create net_external

neutron floatingip-create net_external

6.参考文档：

1.openstack官方文档：http://docs.openstack.org/havana/install-guide/install/apt/openstack-install-guide-apt-havana.pdf 目前openstack官方文档已经做的很好了，如何安装，配置，写的都挺不错的，还有neutron那一节对各种情况的网络结构列出的很详细。
