OpenStack Grizzly Quantum Multihost 部署
黄弘深
本文主要介绍multihost模式下的openstack多节点部署，这种模式可以避免随着节点的增多，流量膨胀一个网络节点无法满足需求的情况。当然如果只是自己搞一台host，在上面虚拟几台VM做实验，或者小型创业公司，通过在五台十台机器上的虚拟化，创建一些VM给公司内部开发测试团队使用，那么使用多节点模式即可，即一个控制节点、一个网络节点、多个计算节点。在Essxi中nova-network的mutihost可以很好分担网络节点的负载，同样在Quantum中也有类似的功能，本文主要参考一位网友Geek的blog所写，做了适当修改，在我的环境里验证没有问题，这里记录下来也仅供大家参考！
环境需求：
管理网络： 172.16.0.0/16
业务网络： 10.10.10.0/24
外部网络： 192.168.80.0/24
我这里使用的是三台机器，你也可以横向扩展，增加计算节点的数量。
| Node Role: | NICs |
| Control Node: | eth0 (192.168.80.21), eth1 (172.16.0.51) |
| Compute1 Node: | eth0(192.168.80.22),eth1(172.16.0.52),eth2(10.10.10.52) |
| Compute2 Node: | eth0(192.168.80.23),eth1(172.16.0.53),eth2(10.10.10.53) |

添加源
添加 Grizzly 源，并升级系统
cat > /etc/apt/sources.list.d/grizzly.list << _ESXU_
deb http://ubuntu-cloud.archive.canonical.com/ubuntu precise-updates/grizzly main
deb http://ubuntu-cloud.archive.canonical.com/ubuntu precise-proposed/grizzly main
_ESXU_
apt-get install ubuntu-cloud-keyring
apt-get update
apt-get upgrade
MySQL & RabbitMQ
- 安装 MySQL：
apt-get install mysql-server python-mysqldb
- 使用sed编辑 /etc/mysql/my.cnf文件的更改绑定地址（0.0.0.0）从本地主机（127.0.0.1）
禁止 mysql 做域名解析，防止连接 mysql出现错误和远程连接 mysql慢的现象。
然后重新启动mysql服务.
sed -i 's/127.0.0.1/0.0.0.0/g' /etc/mysql/my.cnf sed -i '44 i skip-name-resolve' /etc/mysql/my.cnf /etc/init.d/mysql restart
安装 RabbitMQ：
apt-get install rabbitmq-server
NTP
- 安装 NTP 服务
apt-get install ntp
配置NTP服务器计算节点控制器节点之间的同步：
sed -i 's/server ntp.ubuntu.com/server ntp.ubuntu.com\nserver 127.127.1.0\nfudge 127.127.1.0 stratum 10/g' /etc/ntp.conf
service ntp restart
- 开启路由转发
vim /etc/sysctl.conf
net.ipv4.ip_forward=1
Keystone
- 安装 Keystone
apt-get install keystone
在 mysql 里创建 keystone 数据库并授权：
mysql -uroot -p
create database keystone;
grant all on keystone.* to 'keystone'@'%' identified by 'keystone';
quit;
修改 /etc/keystone/keystone.conf 配置文件:
admin_token = www.longgeek.com
debug = True
verbose = True
[sql]
connection = mysql://keystone:keystone@172.16.0.51/keystone #必须写到 [sql] 下面
[signing]
token_format = UUID
启动 keystone 然后同步数据库
/etc/init.d/keystone restart
keystone-manage db_sync
用脚本导入数据：
用脚本来创建 user、role、tenant、service、endpoint，下载脚本：
wget http://192.168.80.8/ubuntu/keystone.sh
修改脚本内容：
ADMIN_PASSWORD=${ADMIN_PASSWORD:-password}
SERVICE_PASSWORD=${SERVICE_PASSWORD:-password}
export SERVICE_TOKEN="admin"
export SERVICE_ENDPOINT="http://172.16.0.51:35357/v2.0"
SERVICE_TENANT_NAME=${SERVICE_TENANT_NAME:-service}
KEYSTONE_REGION=RegionOne
# If you need to provide the service, please to open keystone_wlan_ip and swift_wlan_ip
# of course you are a multi-node architecture, and swift service
# corresponding ip address set the following variables
KEYSTONE_IP="172.16.0.51"
#KEYSTONE_WLAN_IP="172.16.0.51"
SWIFT_IP="172.16.0.51"
#SWIFT_WLAN_IP="172.16.0.51"
COMPUTE_IP=$KEYSTONE_IP
EC2_IP=$KEYSTONE_IP
GLANCE_IP=$KEYSTONE_IP
VOLUME_IP=$KEYSTONE_IP
QUANTUM_IP=$KEYSTONE_IP
在这里更改你的管理员密码即可，IP地址也可根据自己环境更改下！
执行脚本：
sh keystone.sh
设置环境变量：
这里变量对于 keystone.sh 里的设置：
cat > /etc/profile << _ESXU_
export OS_TENANT_NAME=admin #这里如果设置为 service 其它服务会无法验证.
export OS_USERNAME=admin
export OS_PASSWORD=password
export OS_AUTH_URL=http://172.16.0.51:5000/v2.0/
export OS_REGION_NAME=RegionOne
export SERVICE_TOKEN=admin
export SERVICE_ENDPOINT=http://172.16.0.51:35357/v2.0/
_ESXU_
# source /root/profile #使环境变量生效

Horizon
- 安装 horizon：
apt-get install openstack-dashboard memcached
如果你不喜欢 Ubuntu 的主题，可以禁用它，使用默认界面：
sed -i 's/127.0.0.1/172.16.0.51/g' /etc/openstack-dashboard/local_settings.py sed -i 's/127.0.0.1/172.16.0.51/g' /etc/memcached.conf vim /etc/openstack-dashboard/local_settings.py DEBUG = True # Enable the Ubuntu theme if it is present. #try: # from ubuntu_theme import * #except ImportError: # pass
重新加载 apache2 和 memcache：
/etc/init.d/apache2 restart
/etc/init.d/memcached restart
现在可以通过浏览器 http://192.168.8.51/horizon 使用 admin:password 来登录界面。
所有计算节点
网络设置
所有计算节点安装方法相同，只需要替换 IP 地址即可：

添加源
- 添加 Grizzly 源，并升级系统
cat > /etc/apt/sources.list.d/grizzly.list << _GEEK_ deb http://ubuntu-cloud.archive.canonical.com/ubuntu precise-updates/grizzly main deb http://ubuntu-cloud.archive.canonical.com/ubuntu precise-proposed/grizzly main _GEEK_ apt-get update apt-get upgrade apt-get install ubuntu-cloud-keyring
- 设置 ntp 和开启路由转发:
# apt-get install ntp # sed -i 's/server ntp.ubuntu.com/server 172.16.0.51/g' /etc/ntp.conf # service ntp restart # vim /etc/sysctl.conf net.ipv4.ip_forward=1 # sysctl -p
OpenVSwitch
- 安装 openVSwitch:
必须按照下面安装顺序:
apt-get install openvswitch-datapath-source module-assistant auto-install openvswitch-datapath apt-get install openvswitch-switch openvswitch-brcompat
设置 ovs-brcompatd 启动：
sed -i 's/# BRCOMPAT=no/BRCOMPAT=yes/g' /etc/default/openvswitch-switch echo 'brcompat' >> /etc/modules
启动 openvswitch-switch:
/etc/init.d/openvswitch-switch restart
* ovs-brcompatd is not running # brcompatd 没有启动,尝试再次启动.
* ovs-vswitchd is not running
* ovsdb-server is not running
* Inserting openvswitch module
* /etc/openvswitch/conf.db does not exist
* Creating empty database /etc/openvswitch/conf.db
* Starting ovsdb-server
* Configuring Open vSwitch system IDs
* Starting ovs-vswitchd
* Enabling gre with iptables
再次启动,直到 ovs-brcompatd、ovs-vswitchd、ovsdb-server等服务都启动：
# /etc/init.d/openvswitch-switch restart # lsmod | grep brcompat brcompat 13512 0 openvswitch 84038 7 brcompat
如果还是启动不了的话，用下面命令：
/etc/init.d/openvswitch-switch force-reload-kmod
创建网桥：
ovs-vsctl add-br br-int # br-int 用于 vm 整合 ovs-vsctl add-br br-ex # br-ex 用于从互联网上访问 vm ovs-vsctl add-port br-ex eth0 # br-ex 桥接到 eth0
- 重启网卡可能会出现：
/etc/init.d/networking restart
RTNETLINK answers: File exists
Failed to bring up br-ex.
br-ex 可能有 ip 地址，但没有网关和 DNS，需要手工配置一下，或者重启机器. 重启机器后就正常了
- 查看桥接的网络
ovs-vsctl list-br
ovs-vsctl show
- 安装 Quantum openvswitch agent, metadata-agent l3 agent 和 dhcp agent:
apt-get install quantum-plugin-openvswitch-agent quantum-dhcp-agent quantum-l3-agent quantum-metadata-agent
- 编辑 /etc/quantum/quantum.conf 文件：

- 创建一个卷组，命名为 cinder-volumes:
创建一个普通分区，我这里用的sdb，创建了一个主分区，大小为所有空间
# fdisk /dev/sdb n p 1 Enter Enter t 8e w # partx -a /dev/sdb # pvcreate /dev/sdb1 # vgcreate cinder-volumes /dev/sdb1 # vgs VG #PV #LV #SN Attr VSize VFree cinder-volumes 1 7 0 wz--n- 1.64t 75.50g
- 同步数据库并重启服务：
cinder-manage db sync
/etc/init.d/cinder-api restart
/etc/init.d/cinder-scheduler restart
/etc/init.d/cinder-volume restart
最后，我们需要执行：
/etc/init.d/iscsitarget stop
具体请看这里
Nova
- 安装 nova-compute:

启动 nova-compute 服务：
service nova-compute restart
检查 nova 相关服务笑脸：
发现 compute 节点已经加入：
# nova-manage service list Binary Host Zone Status State Updated_At nova-cert control internal enabled :-) 2013-05-07 07:09:56 nova-conductor control internal enabled :-) 2013-05-07 07:09:55 nova-consoleauth control internal enabled :-) 2013-05-07 07:09:56 nova-scheduler control internal enabled :-) 2013-05-07 07:09:56 nova-compute node-02 nova enabled :-) 2013-05-07 07:10:03 nova-compute node-03 nova enabled :-) 2013-05-07 07:10:03
到这里，计算节点就成功加入了，我们可以尝试新建节点验证是否成功，具体horizon的使用方法，后面再写文章详细介绍，主要就是网络的创建这块稍微有点复杂，需要稍微注意下！
