双网卡下安装配置Openstack Folsom + Quantum + Openvswitch过程
Openstack Folsom 发布好久了，但由于新的组件Quantum的加入，以及知识的跨度，比如同时需要系统管理及网络工程方面的知识，所以Folsom的安装还是挺费事的。
经过几天的测试，参考各种文档，终于完成了Folsom基于双网卡的安装，总结至此。
1. 需求说明
====================
:节点名称: NICs
:控制节点: eth0 (100.10.10.51), eth1 (192.168.100.51)
:网络节点: eth0 (100.10.10.52), eth2 (0.0.0.0)
:计算节点: eth0 (100.10.10.53)
**备注 1: ** 本文为双网卡安装Folsom设计,根据官方说明，网络节点最好采用三块网卡控制节点可以和计算节点合二为一.
**备注 2：** 本文安装指南环境为实现Folsom功能评估，力求简单方便，安全性差，不可用于生产环境。
**备注 3: ** 本文不适用于虚拟机环境.请使用物理计算机安装.

2. 控制节点
===============
2.1. 准备系统
-----------------
* 安装系统注意事项::
- ubuntu-12.10-server-amd64.iso
- 为Cinder服务预留独立分区 例如: /dev/sda5
- 提前定义好各服务器主机名及ＩＰ，尽量别改，一定要改，请修改/etc/hosts中的对应关系
* 以下所有命令均在root权限下完成，所以在装好ubuntu后，请切换到root::
sudo passwd
su
* 更新系统(依据笔者经验，安装完Folsom环境后最好别再使用dist-upgrade,以免产生些许小问题，如虚拟机获得不了ip等..)::
apt-get update
apt-get upgrade
apt-get dist-upgrade
* 因为要更新和下载的软件比较多，可以在空闲时间一次更新系统并提前安装所需要软件，以后只需要配置就行了:也可以使用squid代理，这样，其它几台机器不用连外网更新软件了
apt-get update && apt-get dist-upgrade -y && apt-get update -y && apt-get dist-upgrade -y && apt-get install -y rabbitmq-server ntp vlan bridge-utils keystone curl openssl glance quantum-server quantum-plugin-openvswitch nova-api nova-cert novnc nova-consoleauth nova-scheduler nova-novncproxy cinder-api cinder-scheduler cinder-volume iscsitarget open-iscsi iscsitarget-dkms openstack-dashboard memcached python-mysqldb mysql-server
2.2.配置网卡
------------
* 主控应该有一个外网网卡::
#访问Openstack ＡＰＩ
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
#管理网络和虚拟机网络合二为一
auto eth0
iface eth0 inet static
address 100.10.10.51
netmask 255.255.255.0
* 重新启动网络服务::
service networking restart
2.3. MySQL & RabbitMQ
------------
* 安装 MySQL 和 RabbitMQ::
apt-get install mysql-server python-mysqldb rabbitmq-server
* 配置Mysql监听所有地址::
sed -i 's/127.0.0.1/0.0.0.0/g' /etc/mysql/my.cnf
service mysql restart
* 为了简化安装，以后所有连接mysql服务均使用 root:password登录,将root权限更改为所有主机可以访问(默认只能本机访问)
mysql -uroot -ppassword
use mysql;
update user set host='%' where user='root' and host='localhost';
flush privileges;
* 创建所有必须的数据库::
create database keystone;
create database nova;
create database glance;
create database cinder;
create database quantum;
2.4. 节点时间同步
------------------
* 安装时间服务器,其它节点时间同此服务器同步::
apt-get install ntp
sed -i 's/server ntp.ubuntu.com/server ntp.ubuntu.comserver 127.127.1.0fudge 127.127.1.0 stratum 10/g' /etc/ntp.conf
service ntp restart
2.5. Others
-------------------
* 安装其它服务::
apt-get install vlan bridge-utils
* 允许IP转发::
vi /etc/sysctl.conf
net.ipv4.conf.all.rp_filter = 0
net.ipv4.conf.default.rp_filter = 0
sysctl net.ipv4.ip_forward=1
# 检查一下
sysctl -p
2.6. Keystone
-------------------
* 安装组件::
apt-get install keystone
* 编辑 /etc/keystone/keystone.conf 数据库连接::
connection = mysql://root:password@100.10.10.51/keystone
* 重新启动keystone并初始化数据库::
service keystone restart
keystone-manage db_sync
* 使用 `自动化脚本 <https://github.com/888888/OpenStack-Folsom-Install-guide/tree/GRE/2NICs/Keystone_Scripts>`_ 创建keystone用户、服务、服务端点。为了简化，这里只创建admin一个用户，请不要修改此用户密码。
bash keystone_basic.sh
执行一次，否则会创建多个service
bash keystone_endpoints_basic.sh
* 创建/root/novarc文件，写入以下内容::
export OS_TENANT_NAME=admin
export OS_TENANT_ID=c7fb80d964a24ab1bc0fd370696c804e
export OS_USERNAME=admin
export OS_PASSWORD=password
export OS_AUTH_URL="http://127.0.0.1:35357/v2.0"
export OS_REGION_NAME=RegionOne
export OS_IDENTITY_API_VERSION=2.0
export SERVICE_TOKEN=ADMIN
export SERVICE_ENDPOINT="http://127.0.0.1:35357/v2.0"
各项值请根据实际情况替换
keystone tenant-list
将获取的tenant_id替换到novarc
source /root/novarc
echo "source /root/novarc" >> ~/.bashrc
2.7. Glance
-------------------
* 安装组件
apt-get install glance
* 分别修改 /etc/glance/glance-api-paste.ini 和/etc/glance/glance-registry-paste.ini::
[filter:authtoken]
paste.filter_factory = keystone.middleware.auth_token:filter_factory
auth_host = 100.10.10.51
auth_port = 35357
auth_protocol = http
admin_tenant_name = admin
admin_user = admin
admin_password = password
* 分别修改 /etc/glance/glance-api.conf 和/etc/glance/glance-registry.conf ::
sql_connection = mysql://root:password@100.10.10.51/glance
[paste_deploy]
flavor = keystone
* 重新启动glance服务并同步glance数据库::
service glance-api restart; service glance-registry restart
glance-manage db_sync
* 测试glance 服务，不输出任何结果代表成功::
glance index
* 上传个镜像::
wget https://launchpad.net/cirros/trunk/0.3.0/+download/cirros-0.3.0-x86_64-disk.img
glance image-create --name myFirstImage --is-public true --container-format bare
--disk-format qcow2 < cirros-0.3.0-x86_64-disk.img
* 再查看一下::
glance image-list
2.8. Quantum
-------------------

5. 创建虚拟机
============
* 使用 <http://192.168.10.51/horizon> 管理虚拟机
* 编辑安全组，允许所有协议,tcp,udp,icmp
root@sm1u07:~# nova secgroup-list-rules default
Please enter password for encrypted keyring:
+-------------+-----------+---------+-----------+--------------+
| IP Protocol | From Port | To Port | IP Range | Source Group |
+-------------+-----------+---------+-----------+--------------+
| icmp | -1 | 255 | 0.0.0.0/0 | |
| tcp | 1 | 65535 | 0.0.0.0/0 | |
| udp | 1 | 65535 | 0.0.0.0/0 | |
+-------------+-----------+---------+-----------+--------------+
* 使用脚本 `quantum.sh <https://raw.github.com/888888/OpenStack-Folsom-Install-guide/GRE/2NICs/Keystone_Scripts/quantum.sh>`_ 为admin创建相关的网络，即虚拟机内网和外网
* 查看创建好的网络
root@hp4u:~# quantum net-list
+--------------------------------------+-----------+--------------------------------------+
| id | name | subnets |
+--------------------------------------+-----------+--------------------------------------+
| 14dbb282-c74a-4784-bfc3-351f7ca3d034 | ext_net | 95bddb90-84dc-4579-99b8-798a393a3edf |
| d402e168-cbda-4345-8ffa-015e6a1c4aa1 | admin-net | 8ef3c4dd-a265-421c-afa2-6cff28ae2c74 |
+--------------------------------------+-----------+--------------------------------------+
root@hp4u:~# quantum router-list
+--------------------------------------+-----------------+--------------------------------------------------------+
| id | name | external_gateway_info |
+--------------------------------------+-----------------+--------------------------------------------------------+
| 623b68f4-967a-4028-9a92-dc5a7d3e16e8 | provider-router | {"network_id": "14dbb282-c74a-4784-bfc3-351f7ca3d034"} |
+--------------------------------------+-----------------+--------------------------------------------------------+
* 修改 /etc/quantum/l3_agent.ini :
gateway_external_network_id = 14dbb282-c74a-4784-bfc3-351f7ca3d034
router_id = 623b68f4-967a-4028-9a92-dc5a7d3e16e8
service quantum-l3-agent restart
* 使用控制面板创建一个虚拟机，并记录vm-uuid，勇冠vm-uuid获取vm的端口id
quantum port-list -- --device_id <vm-uuid>
* 目前horizon不支持quantum的floatingip操作,通过quantum 命令行为vm 分配floatingip,
quantum floatingip-create --port_id <port_id> <ext_net_id>
* 大功告成，现在你可以去dashboard中用vnc登录vm，测试一下各个网络是否通畅
