openstack三个节点icehouse-gre模式部署

一、环境准备

1、架构

创建3台虚拟机，分别作为controll节点、network节点和compute1节点。

Controller节点：1processor，2G memory,5G storage。

Network节点：1processor，2G memory,5G storage。

Comute1节点：1processor，2G memory,5G storage。

架构图：

外部网络：提供上网业务，外界登录openstack（在上图为蓝色模块）

管理网络：三节点通信比如keystone，认证，rabbitmq消息队列。（在上图为红色模块）

业务网络：网络节点和计算节点中虚拟机数据通信，比如dhcp，L2，L3。（在上图为绿色模块）

2、三个节点网卡配置

Controller节点：一张网卡，配置eth0为管理网络

# 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

auto eth0
iface eth0 inet static
address 10.1.101.11
netmask 255.255.255.0
gateway 10.1.101.254
dns-nameservers 10.1.101.51

配置/etc/hosts如下：

root@ubuntu:~# cat /etc/hosts
127.0.0.1       localhost
#127.0.1.1      ubuntu
#controller
10.1.101.11    controller

#network
10.1.101.21    network

#compute1
10.1.101.31    compute1

# The following lines are desirable for IPv6 capable hosts
::1     ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters

Network节点：三张网卡，配置eth0为管理网络，eth1为业务网络，eth2为外部网络，需特殊配置。

root@ubuntu:~# cat /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

auto eth0
iface eth0 inet static
address 10.1.101.21
netmask 255.255.255.0
gateway 10.1.101.254
dns-nameservers 10.1.101.51

auto eth1
iface eth1 inet static
address 10.0.1.21
netmask 255.255.255.0

# The external network interface
auto eth2
iface eth2 inet manual
up ip link set dev $IFACE up
down ip link set dev $IFACE down

配置/etc/hosts如下：

root@ubuntu:~# cat /etc/hosts
127.0.0.1       localhost
#127.0.1.1      ubuntu
#network
10.1.101.21    network

#controller
10.1.101.11    controller

#compute1
10.1.101.31    compute1

# The following lines are desirable for IPv6 capable hosts
::1     ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters

Comput节点：两张网卡，配置eth0为管理网络，配置eth1为业务网络。

root@ubuntu:~# cat /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

auto eth0
iface eth0 inet static
address 10.1.101.31
netmask 255.255.255.0
gateway 10.1.101.254
#dns-nameservers 192.168.1.3
dns-nameservers 10.1.101.51

auto eth1
iface eth1 inet static
address 10.0.1.31
netmask 255.255.255.0

配置/etc/hosts如下：

root@ubuntu:~# cat /etc/hosts
127.0.0.1       localhost
#127.0.1.1      ubuntu

#compute1
10.1.101.31    compute1

#controller
10.1.101.11    controller

#network
10.1.101.21    network

# The following lines are desirable for IPv6 capable hosts
::1     ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters

3、确认网络已经配置好

Controller节点：

# ping -c 4 openstack.org【ping通外网】

# ping -c 4 network【ping通网络节点的管理网络】

# ping -c 4 compute1【ping通计算节点的管理网络】

Network节点：

# ping -c 4 openstack.org【ping通外网】

# ping -c 4 controller【ping 通控制节点的管理网络】

# ping -c 4 10.0.1.31【ping 通计算节点的tunnel网络】

Compute节点：

# ping -c 4 openstack.org【ping外网通】

# ping -c 4 controller【ping 控制节点的管理网络通】

# ping -c 4 10.0.1.21【ping 通网络节点的tunnel网络】

二、基础环境配置

1、设置全局环境变量

为了方便配置后续配置，先设置全局的环境变量。

controller节点设置：

cat > /root/novarc << EOF
export OS_USERNAME=admin
export OS_PASSWORD=password
export OS_TENANT_NAME=admin
export OS_AUTH_URL=http://controller:35357/v2.0
export SERVICE_ENDPOINT="http://controller:35357/v2.0"
export SERVICE_TOKEN=servicetoken
export MYSQL_PASS=password
export SERVICE_PASSWORD=password
export RABBIT_PASSWORD=password
export MASTER="10.1.101.11"
EOF
cat /root/novarc >> /etc/profile
source /etc/profile

compute节点设置：

# Create the environment variables
cat > /root/novarc << EOF
export OS_TENANT_NAME=admin
export OS_USERNAME=admin
export OS_PASSWORD=password
export MYSQL_PASS=password
export SERVICE_PASSWORD=password
export RABBIT_PASSWORD=password
export SERVICE_TOKEN=stackinsider
export CONTROLLER_IP=controller
export MASTER=compute
export LOCAL_IP="$(/sbin/ifconfig eth1        | awk ‘/inet addr/ {print $2}‘ | cut -f2 -d ":")"
EOF

# Update the global environment variables.
cat /root/novarc >> /etc/profile
source /etc/profile

2、更新系统

在三个节点都要执行下面操作。

第一步、安装Ubuntu Cloud Archive

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

Ubuntu Cloud Archive是一个特殊的库允许你安装Ubuntu支持的稳定的最新发布的OpenStack。

第二步、更新系统

# apt-get update
# apt-get dist-upgrade 【//lxy:需要十分钟，耐心等待】

第三步，安装Ubuntu 13.10 backported kernel

Ubuntu12.04需要安装这个Linux kernel来提升系统的稳定性。

# apt-get install linux-image-generic-lts-saucy

第四步，重启系统生效

# reboot

3、安装NTP（Network Time Protocal）

为做到每个节点的时间同步，需要在每个节点都安装ntp，然后修改配置，将/etc/ntp.conf添加controller为时间源。

在controller节点：

第一步、安装

# apt-get install ntp

第二步、配置/etc/ntp.conf

# Use Ubuntu‘s ntp server as a fallback.
server ntp.ubuntu.comserver 127.127.1.0
fudge 127.127.1.0 stratum 10

将ntp.ubuntu.com作为时间源，此外添加一个本地时间源，以防网络时间服务中断，其中server 127.127.1.0表示本机是ntp服务器。

或者执行下面命令：

sed -i ‘s/server ntp.ubuntu.com/ server ntp.ubuntu.com server 127.127.1.0 fudge 127.127.1.0 stratum 10/g‘ /etc/ntp.conf

第三步，重启ntp服务。

#service ntp restart

在controller之外的节点，

第一步，安装

# apt-get install ntp

第二步，配置/etc/ntp.conf，将controller作为时间源。

# Use Ubuntu‘s ntp server as a fallback.
server controller

或者执行命令：

sed -i -e " s/server ntp.ubuntu.com/server controller/g" /etc/ntp.conf

第三步：重启NTP服务。

4、安装数据库

每个节点都要安装python-mysqldb组件，用于数据库连接，只有主控需要安装mysqlserver。

controller节点：

第一步安装：

# apt-get install python-mysqldb mysql-server

Note:安装过程终端会提醒输入mysql root账户的密码，这里设置为password。

第二步，配置/etc/mysql/my.conf文件

将[mysqld]模块中bind-address设置为controller节点管理网络的ip，确保其他节点通过管理网络获取Mysql服务。也可以设置为0.0.0.0，就是将mysql服务绑定到所有网卡。

[mysqld]
...
bind-address = 10.1.101.11

在[mysqld]模块bind-address后面增加如下配置，来设置UTF-8字符集和InnoDB。

[mysqld]
...
default-storage-engine = innodb
collation-server = utf8_general_ci
init-connect = ‘SET NAMES utf8‘
character-set-server = utf8

第三步，重启mysql服务使设置生效

# service mysql restart

第四步，删除匿名用户

数据库第一次启动时会创建一些匿名用户，必须将这些用户删除，否则后面数据库连接会出错。

# mysql_secure_installation

Note:

1、该命令提供一堆选择给你来改善mysql数据库的安全性，除了不要改密码，其他都选yes，除非有你自己的理由。

2、如果mysql_secure_installation命令失败则执行

# mysql_install_db

# mysql_secure_installation

第五步，创建OpenStack中的Database,Users,Privileges

mysql -uroot -p$MYSQL_PASS << EOF
CREATE DATABASE nova;
GRANT ALL PRIVILEGES ON nova.* TO ‘nova‘@‘%‘ IDENTIFIED BY ‘$MYSQL_PASS‘;
GRANT ALL PRIVILEGES ON nova.* TO ‘nova‘@‘localhost‘ IDENTIFIED BY ‘$MYSQL_PASS‘;
GRANT ALL PRIVILEGES ON nova.* TO ‘nova‘@‘controller‘ IDENTIFIED BY ‘$MYSQL_PASS‘;
CREATE DATABASE glance;
GRANT ALL PRIVILEGES ON glance.* TO ‘glance‘@‘%‘ IDENTIFIED BY ‘$MYSQL_PASS‘;
GRANT ALL PRIVILEGES ON glance.* TO ‘glance‘@‘localhost‘ IDENTIFIED BY ‘$MYSQL_PASS‘;
GRANT ALL PRIVILEGES ON glance.* TO ‘glance‘@‘controller‘ IDENTIFIED BY ‘$MYSQL_PASS‘;
CREATE DATABASE keystone;
GRANT ALL PRIVILEGES ON keystone.* TO ‘keystone‘@‘%‘ IDENTIFIED BY ‘$MYSQL_PASS‘;
GRANT ALL PRIVILEGES ON keystone.* TO ‘keystone‘@‘localhost‘ IDENTIFIED BY ‘$MYSQL_PASS‘;
GRANT ALL PRIVILEGES ON keystone.* TO ‘keystone‘@‘controller‘ IDENTIFIED BY ‘$MYSQL_PASS‘;
CREATE DATABASE cinder;
GRANT ALL PRIVILEGES ON cinder.* TO ‘cinder‘@‘%‘ IDENTIFIED BY ‘$MYSQL_PASS‘;
GRANT ALL PRIVILEGES ON cinder.* TO ‘cinder‘@‘localhost‘ IDENTIFIED BY ‘$MYSQL_PASS‘;
GRANT ALL PRIVILEGES ON cinder.* TO ‘cinder‘@‘controller‘ IDENTIFIED BY ‘$MYSQL_PASS‘;
CREATE DATABASE neutron;
GRANT ALL PRIVILEGES ON neutron.* TO ‘neutron‘@‘%‘ IDENTIFIED BY ‘$MYSQL_PASS‘;
GRANT ALL PRIVILEGES ON neutron.* TO ‘neutron‘@‘localhost‘ IDENTIFIED BY ‘$MYSQL_PASS‘;
GRANT ALL PRIVILEGES ON neutron.* TO ‘neutron‘@‘controller‘ IDENTIFIED BY ‘$MYSQL_PASS‘;
FLUSH PRIVILEGES;
EOF

在controller之外的节点安装python-mysqldb

# apt-get install python-mysqldb

5、安装消息代理RabbitMQ

第一步，安装

# apt-get -y install rabbitmq-server

第二步，改密码

RabbitMQ默认创建一个用户，用户名密码都是guest，执行以下命令将guest用户的密码改为password

#rabbitmqctl change_password guest $RABBIT_PASSWORD

在用到RabbitMQ的openstack服务配置文件中都要修改rabbit_password。

三、安装OpenStack服务

1、安装keystone

在controller节点安装OpenStack认证服务.

第一步、安装keystone

# apt-get install keystone

第二步、配置/etc/keystone/keystone.conf

sed -i -e " s/#admin_token=ADMIN/admin_token=$SERVICE_TOKEN/g; s/#public_bind_host=0.0.0.0/public_bind_host=0.0.0.0/g; s/#admin_bind_host=0.0.0.0/admin_bind_host=0.0.0.0/g; s/#public_port=5000/public_port=5000/g; s/#admin_port=35357/admin_port=35357/g; s/#compute_port=8774/compute_port=8774/g; s/#verbose=false/verbose=True/g; s/#idle_timeout=3600/idle_timeout=3600/g" /etc/keystone/keystone.conf

更新keystone.conf中MySQL连接

[database]
# The SQLAlchemy connection string used to connect to the database
connection = mysql://keystone:KEYSTONE_DBPASS@controller/keystone

或者执行命令

sed -i ‘/connection = .*/{s|sqlite:///.*|mysql://‘"keystone"‘:‘"$MYSQL_PASS"‘@‘"$MASTER"‘/keystone|g}‘      /etc/keystone/keystone.conf

第三步、删除keystone.db

默认情况，Ubuntu包创建了一个SQLite数据库。删除/var/lib/keystone/目录下的keystone.db文件确保后面不会出错。

# rm /var/lib/keystone/keystone.db

第四步、重启keystone并同步数据库

# service keystone restart
# keystone-manage db_sync

第五步、创建OpenStack中的users, tenants, services

首先创建Keystone数据导入脚本Ksdata.sh ，内容如下：

vi Ksdata.sh 

#!/bin/sh
#
# Keystone Datas
#

keystone user-role-add --tenant-id $SERVICE_TENANT --user-id $CINDER_USER --role-id $ADMIN_ROLE

运行脚本

#bash Ksdata.sh

第六步，创建endpoints

首先创建脚本Ksendpoints.sh

#vi Ksendpoints.sh
#!/bin/sh
#

  create_endpoint $i $id
done

运行脚本

# bash Ksendpoints.sh

第七步，验证

现在keystone已经安装完成，验证身份认证服务安装是否正确。

# keystone user-list
# keystone user-role-list --user admin --tenant admin

2、安装OpenStack客户端

安装完后，可以通过命令来调用OpenStack各个服务的api。

# apt-get install python-pip
# pip install python-keystoneclient
# pip install python-cinderclient
# pip install python-novaclient
# pip install python-glanceclient
# pip install python-neutronclient
# 也可以用到时再安装
# pip install python-swiftclient
# pip install python-heatclient
# pip install python-ceilometerclient
# pip install python-troveclient

3、安装Glance(镜像服务)

在controller节点安装image服务

第一步、安装glance。

# apt-get install glance

第二步、配置

因为glance包含两类服务所以修改配置文件/etc/glance/glance-api.conf和/etc/glance/glanceregistry.conf

sed -i -e " s/%SERVICE_TENANT_NAME%/service/g; s/%SERVICE_USER%/glance/g; s/%SERVICE_PASSWORD%/$SERVICE_PASSWORD/g; " /etc/glance/glance-api.conf  /etc/glance/glance-registry.conf

修改两个文件中[database]模块数据库连接，

connection = mysql://glance:password@controller/glance

或直接执行命令

sed -i ‘/#connection = <None>/i\connection = mysql://‘glance‘:‘"$MYSQL_PASS"‘@‘"$MASTER"‘/glance‘ /etc/glance/glance-registry.conf /etc/glance/glance-api.conf

在[DEFAULT]中增加以下配置

[DEFAULT]
rpc_backend = rabbit
rabbit_host = controller
rabbit_password = RABBIT_PASS

设置flavor为keystone

sed -i ‘s/#flavor=/flavor=keystone/g‘ /etc/glance/glance-api.conf /etc/glance/glance-registry.conf

第三步、删除glance.sqlite

# rm /var/lib/glance/glance.sqlite

第四步、检查配置

[keystone_authtoken]
#auth_host = 127.0.0.1
auth_uri = http://controller:5000
auth_host = controller
auth_port = 35357
auth_protocol = http
admin_tenant_name = service

auth_host = $CONTROLLER_IP
auth_port = 35357
auth_protocol = http
admin_tenant_name = service
admin_user = nova
admin_password = $SERVICE_PASSWORD
EOF

第五步、删除nova.sqlite数据库

# rm /var/lib/nova/nova.sqlite

第六步、配置/etc/nova/nova-compute.conf，使用qemu而非kvm。

# vi /etc/nova/nova-compute.conf
[DEFAULT]
compute_driver=libvirt.LibvirtDriver
[libvirt]
virt_type=qemu

第七步、重启服务

# service nova-compute restart

第八步、检查nova服务是否安装成功（确保nova-cert、nova-consoleauth、nova-scheduler、nova-conductor和nova-compute均开启）

# nova-manage service list

6、安装neutron(网络服务)

controller节点：

第一步、安装neutron 组件

# apt-get install neutron-server neutron-plugin-ml2

第二步、配置/etc/neutron/neutron.conf

需要配置包括数据库，认证，消息代理，拓扑改变通知和plugin。

数据库连接

sed -i ‘/connection = .*/{s|sqlite:///.*|mysql://‘"neutron"‘:‘"$MYSQL_PASS"‘@‘"$CONTROLLER_IP"‘/neutron|g}‘         /etc/neutron/neutron.conf

身份验证

sed -i ‘s/# auth_strategy = keystone/auth_strategy = keystone/g‘         /etc/neutron/neutron.conf

sed -i -e " s/%SERVICE_TENANT_NAME%/service/g; s/%SERVICE_USER%/neutron/g;           s/%SERVICE_PASSWORD%/$SERVICE_PASSWORD/g;           s/auth_host = 127.0.0.1/auth_host = $CONTROLLER_IP/g" /etc/neutron/neutron.conf

配置消息代理

sed -i -e " s/# rpc_backend = neutron.openstack.common.rpc.impl_kombu/rpc_backend = neutron.openstack.common.rpc.impl_kombu/g;           s/# rabbit_host = localhost/rabbit_host = $CONTROLLER_IP/g;           s/# rabbit_password = guest/rabbit_password = $SERVICE_PASSWORD/g;           s/# rabbit_userid = guest/rabbit_userid = guest/g"           /etc/neutron/neutron.conf

配置网络拓扑改变通知compute

service_id=`keystone tenant-get service | awk ‘$2~/^id/{print $4}‘`

sed -i -e " s/# notify_nova_on_port_status_changes = True/notify_nova_on_port_status_changes = True/g;             s/# notify_nova_on_port_data_changes = True/notify_nova_on_port_data_changes = True/g;             s/# nova_url = http:\/\/127.0.0.1:8774\/v2/nova_url = http:\/\/$MASTER:8774\/v2/g;             s/# nova_admin_username =/nova_admin_username = nova/g;         s/# nova_admin_tenant_id =/nova_admin_tenant_id = $service_id/g;             s/# nova_admin_password =/nova_admin_password = $SERVICE_PASSWORD/g;         s/# nova_admin_auth_url =/nova_admin_auth_url = http:\/\/$MASTER:35357\/v2.0/g"             /etc/neutron/neutron.conf其中，# keystone tenant-get service用来获得service租户的id

配置ML2 plug-in

sed -i -e ‘s/core_plugin = neutron.plugins.ml2.plugin.Ml2Plugin/core_plugin = ml2/g‘ /etc/neutron/neutron.conf
sed -i -e ‘s/# service_plugins =/service_plugins = router/g‘ /etc/neutron/neutron.conf
sed -i -e ‘s/# allow_overlapping_ips = False/allow_overlapping_ips = True/g‘ /etc/neutron/neutron.conf

第三步、配置/etc/neutron/plugins/ml2/ml2_conf.ini

ML2代理使用OVS代理来创建虚拟网络架构。然而，controller节点不需要OVS代理或服务，因为controller节点不处理虚拟机网络通信。

在[ml2]模块，[ml2_type_gre]模块增加以下配置，并增加[securitygroup]新模块的配置。

[ml2]
type_drivers = gre
tenant_network_types = gre
mechanism_drivers =openvswitch

[ml2_type_gre]
tunnel_id_ranges =1:1000

[securitygroup]
# Controls if neutron security group is enabled or not.
# It should be false when you use nova security group.
firewall_driver = neutron.agent.linux.iptables_firewall.OVSHybridIptablesFirewallDriver
enable_security_group = True

第四步、配/etc/nova/nova.conf

默认情况，虚拟机会使用legacy networking，所以必须配置。确认按照下面配置。

network_api_class = nova.network.neutronv2.api.API
neutron_url = http://10.1.101.11:9696
neutron_auth_strategy = keystone
neutron_admin_tenant_name = service
neutron_admin_username = neutron
neutron_admin_password = password
neutron_admin_auth_url = http://10.1.101.11:35357/v2.0
linuxnet_interface_driver = nova.network.linux_net.LinuxOVSInterfaceDriver
firewall_driver = nova.virt.firewall.NoopFirewallDriver
security_group_api = neutron

因为默认虚拟机使用内部防火墙服务，因为Networking有防火墙，所以需要要配置防火墙为firewall_driver = nova.virt.firewall.NoopFirewallDriver

第五步、完成安装

1. Restart the Compute services:
# service nova-api restart
# service nova-scheduler restart
# service nova-conductor restart
2. Restart the Networking service:
# service neutron-server restart

network节点：

第一步、在安装OpenStack之前需要开启一些核心的网络服务，IP转发。

echo "net.ipv4.ip_forward = 1" >> /etc/sysctl.conf
echo "net.ipv4.conf.all.rp_filter=0" >> /etc/sysctl.conf
echo "net.ipv4.conf.default.rp_filter=0" >> /etc/sysctl.conf
sysctl -p

第二步、安装neutron组件

# apt-get install neutron-plugin-ml2 neutron-plugin-openvswitch-agent
openvswitch-datapath-dkms neutron-l3-agent neutron-dhcp-agent

Tip:

【查看Ubuntu版本
root@ubuntu:~# cat /etc/issue
Ubuntu 12.04.2 LTS \n \l
root@ubuntu:~# lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 12.04.2 LTS

如果Ubuntu用的Linux内核版本在3.11或以上就不需要安装openvswitch-datapath-dkms package包。
】

第三步、配置/etc/neutron/neutron.conf

[DEFAULT]模块和[keystone_authtoken]模块

[DEFAULT]
...
auth_strategy = keystonerpc_backend = neutron.openstack.common.rpc.impl_komburabbit_host = controllerrabbit_password = RABBIT_PASScore_plugin = ml2service_plugins = routerallow_overlapping_ips = True
[keystone_authtoken]
...
auth_uri = http://controller:5000
auth_host = controller
auth_protocol = http
auth_port = 35357
admin_tenant_name = service
admin_user = neutron
admin_password = NEUTRON_PASS

注释掉[service_providers]所有行

第四步、配置L3agent /etc/neutron/l3_agent.ini

[DEFAULT]
...
interface_driver = neutron.agent.linux.interface.OVSInterfaceDriver
use_namespaces = True

debug = True

第五步、配置DHCP agent /etc/neutron/dhcp_agent.ini

[DEFAULT]
...
interface_driver = neutron.agent.linux.interface.OVSInterfaceDriver
dhcp_driver = neutron.agent.linux.dhcp.Dnsmasq
use_namespaces = True
debug = True

第六步、配置metadata agent  /etc/neutron/metadata_agent.ini

Metadate代理为远程访问虚拟机授权提供配置信息

[DEFAULT]
...
auth_url = http://controller:5000/v2.0【一定要配置对】
auth_region = regionOne
admin_tenant_name = service
admin_user = neutron
admin_password = NEUTRON_PASS
nova_metadata_ip = controller
metadata_proxy_shared_secret = METADATA_SECRET

下面两步在controller节点完成

1、编辑/etc/nova/nova.conf在[DEFAULT]加上, METADATA_SECRET为对应密码，我改为password。

[DEFAULT]
...
service_neutron_metadata_proxy = true
neutron_metadata_proxy_shared_secret = METADATA_SECRET

2、在controller节点，重启Compute API服务。

# service nova-api restart

第七步、配置ML2 plug-in网络/etc/neutron/plugins/ml2/ml2_conf.ini

在[ml2]模块增加

[ml2]
...
type_drivers = gre
tenant_network_types = gre
mechanism_drivers = openvswitch

在[ml2_type_gre]模块增加

[ml2_type_gre]
...
tunnel_id_ranges = 1:1000

新增[ovs]模块并增加下面内容，其中INSTANCE_TUNNELS_INTERFACE_IP_ADDRESS替换为network节点虚拟机tunnels网络的网卡ip地址。这里为10.0.1.21

[ovs]
...
local_ip = INSTANCE_TUNNELS_INTERFACE_IP_ADDRESS
tunnel_type = gre
enable_tunneling = True

新增[securitygroup]模块并增加

[securitygroup]
...
firewall_driver = neutron.agent.linux.iptables_firewall.
OVSHybridIptablesFirewallDriver
enable_security_group = True

第八步，配置OVS服务

OVS提供底层虚拟机网络架构。br-int处理虚拟机内部网络通信。br-ext处理虚拟机外部网络通信。br-ext需要一个port在物理外网网卡来为虚拟机提供外部网络通信。这个port 桥接虚拟网络和物理外网。

重启OVS服务。

# service openvswitch-switch restart

添加集成网桥

 # ovs-vsctl add-br br-int

添加外部网桥

# ovs-vsctl add-br br-ex

添加外部网卡借以通外网

将INTERFACE_NAME  替换为当前网卡的名字。比如eth2或者ens256.我的是eth2.

# ovs-vsctl add-port br-ex INTERFACE_NAME

然后要配置network节点的/etc/network/interface中的br-ex网卡，完整内容如下：

# 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

auto eth0
iface eth0 inet static
address 10.1.101.21
netmask 255.255.255.0
gateway 10.1.101.254
dns-nameservers 10.1.101.51

auto eth1
iface eth1 inet static
address 10.0.1.21
netmask 255.255.255.0

# The external network interface
auto eth2
iface eth2 inet manual
up ip link set dev $IFACE up
down ip link set dev $IFACE down

auto br-ex
iface br-ex inet static
    address 192.168.100.21
    netmask 255.255.255.0
    up ip link set $IFACE promisc on
    down ip link set $IFACE promisc off

重启服务

/etc/init.d/networking restart

第九步、完成安装

# service neutron-plugin-openvswitch-agent restart
# service neutron-l3-agent restart
# service neutron-dhcp-agent restart
# service neutron-metadata-agent restart

compute节点:

第一步，开启ip转发

echo "net.ipv4.ip_forward = 1" >> /etc/sysctl.conf
echo "net.ipv4.conf.all.rp_filter=0" >> /etc/sysctl.conf
echo "net.ipv4.conf.default.rp_filter=0" >> /etc/sysctl.conf
sysctl -p

第二步、安装neutron组件

# apt-get install neutron-common neutron-plugin-ml2 neutron-plugin-openvswitch-agent
超过3.11的Ubuntu内核版本都不需要安装openvswitch-datapath-dkms，
因为我的Ubuntu版本是3.12所以不需要安装openvswitch-datapath-dkms

第三步、配置/etc/neutron/neutron.conf

需要配置认证服务，消息代理和plugin

认证

[DEFAULT]
...
auth_strategy = keystone

在[keystone_authtoken]模块增加下面内容，要修改NEUTRON_PASS为对应密码，我的是password。

[keystone_authtoken]
...
auth_uri = http://controller:5000
auth_host = controller
auth_protocol = http
auth_port = 35357
admin_tenant_name = service
admin_user = neutron
admin_password = NEUTRON_PASS

消息代理，在[DEFAULT]模块增加下面内容，注意要替换RABBIT_PASS为RabbitMQ的密码。

[DEFAULT]
...
rpc_backend = neutron.openstack.common.rpc.impl_kombu
rabbit_host = controller
rabbit_password = RABBIT_PASS

配置ML2，在[DEFAULT]模块增加下面内容

[DEFAULT]
...
core_plugin = ml2
service_plugins = router
allow_overlapping_ips = True
verbose = True

注释掉[service_providers]模块所有行

第四步、配置ML2 plug-in /etc/neutron/plugins/ml2/ml2_conf.ini

ML2 plug-in用OVS来建立虚拟机网络。

在[ml2]模块增加

[ml2]
...
type_drivers = gre
tenant_network_types = gre
mechanism_drivers = openvswitch

在[ml2_type_gre]模块增加

[ml2_type_gre]
...
tunnel_id_ranges = 1:1000

增加[ovs]模块，并增加下面内容，注意INSTANCE_TUNNELS_INTERFACE_IP_ADDRESS要替换成compute节点虚拟机tunnels网卡的ip，这里是10.0.1.31

[ovs]
...
local_ip = INSTANCE_TUNNELS_INTERFACE_IP_ADDRESS
tunnel_type = gre
enable_tunneling = True

增加[securitygroup]模块，并添加下面内容。

[securitygroup]
...
firewall_driver = neutron.agent.linux.iptables_firewall.
OVSHybridIptablesFirewallDriver
enable_security_group = True

第五步、配置OVS服务

OVS提供底层的虚拟网络框架。Br-int处理虚拟机内部网络流量。

重启OVS服务

# service openvswitch-switch restart

添加集成网桥

# ovs-vsctl add-br br-int

第六步、配置计算服务nova使用neutron /etc/nova/nova.conf

默认虚拟机会使用legacy networking。所以要进行配置使其使用Neutron。

在[DEFAULT]模块增加下面内容：注意要修改NEUTRON_PASS为真正的密码，我的是password。

[DEFAULT]
...
network_api_class = nova.network.neutronv2.api.API
neutron_url = http://controller:9696
neutron_auth_strategy = keystone
neutron_admin_tenant_name = service
neutron_admin_username = neutron
neutron_admin_password = NEUTRON_PASS
neutron_admin_auth_url = http://controller:35357/v2.0
linuxnet_interface_driver = nova.network.linux_net.LinuxOVSInterfaceDriver
firewall_driver = nova.virt.firewall.NoopFirewallDriver
security_group_api = neutron

默认虚拟机会使用内部防火墙，这里为了让它使用Neutron的防火墙，所以配置。nova.virt.firewall.NoopFirewallDriver

第七步、完成配置

重启计算服务

# service nova-compute restart

重启OVS代理

# service neutron-plugin-openvswitch-agent restart

7、安装dashboard

在controller节点安装dashboard

第一步、安装

# apt-get -y install apache2 libapache2-mod-wsgi openstack-dashboard memcached python-memcache

删除openstack-dashboard-ubuntu-theme这个软件包，因为它对一些功能有阻碍作用

# apt-get remove --purge openstack-dashboard-ubuntu-theme

第二步、配置/etc/openstack-dashboard/local_settings.py

修改[‘default‘][‘LOCATION‘]中的CACHES来匹配/etc/memcached.conf的内容。

CACHES = {
‘default‘: {
‘BACKEND‘ : ‘django.core.cache.backends.memcached.MemcachedCache‘,
‘LOCATION‘ : ‘127.0.0.1:11211‘
}
}

修改OPENSTACK_HOST选项为认证服务的机子。

OPENSTACK_HOST = "controller"

第三步、启动apache web服务和memcached

# service apache2 restart
# service memcached restart

第四步、重启keyston服务，并同步数据库

# service keystone restart
# keystone-manage db_sync

现在基本配置都已经完成，可以使用OpenStack了。

以上为我个人配置笔记，仅作参考，更详细介绍请参考官方文档。
