文章 可能会满足你的需求。随着节点的增多、流量的膨胀,一个网络节点很难满足需求。在 Essxi 中 nova-network 的
multihost 可以很好的分担网络节点的负载,同样在 Quantum 中也有类似的功能。具体信息参考 孔令贤 和 陈沙克
的文档。

MySQL & RabbitMQ
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
apt-get install rabbitmq-server
NTP
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
vim /etc/sysctl.conf
net.ipv4.ip_forward=1
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
用脚本来创建 user、role、tenant、service、endpoint,下载脚本:
wget http://download.longgeek.com/openstack/grizzly/keystone.sh
修改脚本内容:
ADMIN_PASSWORD=${ADMIN_PASSWORD:-password} #租户 admin 的密码
SERVICE_PASSWORD=${SERVICE_PASSWORD:-password} #nova,glance,cinder,quantum,swift的密码
export SERVICE_TOKEN="www.longgeek.com" # token
export SERVICE_ENDPOINT="http://172.16.0.51:35357/v2.0"
SERVICE_TENANT_NAME=${SERVICE_TENANT_NAME:-service} #租户 service,包含了nova,glance,ciner,quantum,swift等服务

COMPUTE_IP=$KEYSTONE_IP
EC2_IP=$KEYSTONE_IP
GLANCE_IP=$KEYSTONE_IP
VOLUME_IP=$KEYSTONE_IP
QUANTUM_IP=$KEYSTONE_IP
执行脚本:

这里变量对于 keystone.sh 里的设置:
# cat > /root/export.sh << _GEEK_
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/

# echo 'source /root/export.sh' >> /root/.bashrc
# source /root/export.sh
验证 keystone 的安装,做一个简单测试:
apt-get install curl openssl
curl http://172.16.0.51:35357/v2.0/endpoints -H 'x-auth-token: www.longgeek.com' | python -mjson.tool
Glance
apt-get install glance
创建一个 glance 数据库并授权:
mysql -uroot -p
create database glance;
grant all on glance.* to 'glance'@'%' identified by 'glance';
更新 /etc/glance/glance-api.conf 文件:
verbose = True

auth_protocol = http
admin_tenant_name = service
admin_user = glance
admin_password = password
[paste_deploy]
config_file = /etc/glance/glance-registry-paste.ini

启动 glance-api 和 glance-registry 服务并同步到数据库:
/etc/init.d/glance-api restart
/etc/init.d/glance-registry restart
glance-manage version_control 0
glance-manage db_sync
测试 glance 的安装,上传一个镜像。下载 Cirros 镜像并上传:
wget https://launchpad.net/cirros/trunk/0.3.0/+download/cirros-0.3.0-x86_64-disk.img
glance image-create --name='cirros' --public --container-format=ovf --disk-format=qcow2 < ./cirros-0.3.0-x86_64-disk.img
glance image-list
Cinder
安装 Cinder 需要的包:
apt-get install cinder-api cinder-common cinder-scheduler cinder-volume python-cinderclient iscsitarget open-iscsi iscsitarget-dkms
配置 iscsi 并启动服务:
sed -i 's/false/true/g' /etc/default/iscsitarget
/etc/init.d/iscsitarget restart
/etc/init.d/open-iscsi restart
创建 cinder 数据库并授权用户访问:
mysql -uroot -p
create database cinder;
grant all on cinder.* to 'cinder'@'%' identified by 'cinder';
quit;
修改 /etc/cinder/cinder.conf:
cat /etc/cinder/cinder.conf

debug = False
iscsi_helper = ietadm
auth_strategy = keystone

# DATABASE
sql_connection = mysql://cinder:cinder@172.16.0.51/cinder
# API
osapi_volume_extension = cinder.api.contrib.standard_extensions
修改 /etc/cinder/api-paste.ini 文件末尾 [filter:authtoken] 字段 :
[filter:authtoken]
paste.filter_factory = keystoneclient.middleware.auth_token:filter_factory
service_protocol = http
service_host = 172.16.0.51
service_port = 5000

auth_port = 35357
auth_protocol = http
admin_tenant_name = service
admin_user = cinder
admin_password = password
signing_dir = /var/lib/cinder
创建一个卷组,命名为 cinder-volumes:
这里用文件模拟分区。
dd if=/dev/zero of=/opt/cinder-volumes bs=1 count=0 seek=5G
losetup /dev/loop2 /opt/cinder-volumes
fdisk /dev/loop2
#Type in the followings:
n
p
1
ENTER
ENTER
t
8e
w
分区现在有了,创建物理卷和卷组:
pvcreate /dev/loop2
vgcreate cinder-volumes /dev/loop2
这个卷组在系统重启会失效,把它写到 rc.local 中:
echo 'losetup /dev/loop2 /opt/cinder-volumes' >> /etc/rc.local
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

Nova
安装 Nova 相关软件包:
apt-get install nova-api nova-cert novnc nova-conductor nova-consoleauth nova-scheduler nova-novncproxy
创建 nova 数据库,授权 nova 用户访问它:
mysql -uroot -p
create database nova;

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。

设置 ntp 和开启路由转发:
# apt-get install ntp

# service ntp restart
# vim /etc/sysctl.conf
net.ipv4.ip_forward=1
# sysctl -p
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
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 eth2 # br-ex 桥接到 eth2
做完上面操作后,eth2 这个网卡是没有工作的,需修改网卡配置文件:
# ifconfig eth2 0
# ifconfig br-ex 192.168.8.52/24
# route add default gw 192.168.8.1 dev br-ex
# echo 'nameserver 8.8.8.8' > /etc/resolv.conf

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
文档更新:发现网络节点的 eth2 网卡在系统重启后没有激活,写入到 rc.local中:
echo 'ifconfig eth2 up' >> /etc/rc.local
ovs-vsctl list-br
ovs-vsctl show

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

创建 quantum 网络和虚拟机参照这里。
尝试互相宕掉某个计算节点上的 quantum-dhcp-agent 和 quantum-l3-agent 服务,来验证
Quantum 的 MultiHost,查看创建虚拟机时候是否能 DHCP 或能通过 Float IP 来访问 VM。
