配置linux桥接agent
# mv /etc/neutron/plugins/ml2/linuxbridge_agent.ini /etc/neutron/plugins/ml2/linuxbridge_agent.ini.bak
# vim /etc/neutron/plugins/ml2/linuxbridge_agent.ini增加以下内容

systemctl restart openstack-nova-compute.service
systemctl enable neutron-linuxbridge-agent.service
systemctl start neutron-linuxbridge-agent.service
# systemctl restart openstack-nova-compute.service
# systemctl enable neutron-linuxbridge-agent.service
Created symlink from /etc/systemd/system/multi-user.target.wants/neutron-linuxbridge-agent.service to /usr/lib/systemd/system/neutron-linuxbridge-agent.service.
# systemctl start neutron-linuxbridge-agent.service
# 验证配置(controller)

必须要有4个，否则说明上面的某个步骤配置有问题。
增加dashboard- horizon 【控制节点】
openstack dashboard也被称为Horizon，是一个web界面，使用管理员和用户能够管理openstack不同的资源和服务
dashboard 通过OpenStack APIs操作openstack云计算控制器
Horizon允许定制自己的商标
Horizon提供了核心类和可重复使用的木板和工具
这个部署使用的是 Apache web server.
安装包 yum install -y openstack-dashboard
编辑配置文件
vi /etc/openstack-dashboard/local_settings //更改或增加
OPENSTACK_HOST = "controller" #配置openstack服务dashboard，运行在控制节点
ALLOWED_HOSTS = ['*', ] #允许任何主机访问dashboard
#配置缓存会话存储服务，注意：注释掉其它session存储配置
CACHES = {
'default': {
'BACKEND': 'django.core.cache.backends.locmem.LocMemCache',
'LOCATION': '127.0.0.1:11211',
}
}
OPENSTACK_KEYSTONE_DEFAULT_ROLE = "user"
OPENSTACK_KEYSTONE_MULTIDOMAIN_SUPPORT = True
OPENSTACK_API_VERSIONS = {
"identity": 3,
"volume": 2,
}
TIME_ZONE = "Asia/Chongqing"#时区 重启服务systemctl restart httpd.service memcached.service
此时可以去访问了 http://controller/dashboard 使用账号admin或者demon用户登陆即可，域为default
block storage又叫做cinder，用来给openstack提供存储服务，比如我们在阿里云购买一台云主机，同时想购买容量大的磁盘，通常叫做云盘，这个云盘就是block storage。
创建库并授权cinder用户
mysql -uroot -proot
> CREATE DATABASE cinder;
> GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'localhost' IDENTIFIED BY 'cinder';
> GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'%' IDENTIFIED BY 'cinder';
MariaDB [(none)]> CREATE DATABASE cinder;
Query OK, 1 row affected (0.03 sec)
MariaDB [(none)]> GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'localhost' IDENTIFIED BY 'cinder';
Query OK, 0 rows affected (0.14 sec)
MariaDB [(none)]> GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'%' IDENTIFIED BY 'cinder';
Query OK, 0 rows affected (0.00 sec)
MariaDB [(none)]>
执行初始化脚本
source admin-openrc.sh
创建cinder用户 （密码为cinderpasswd）
openstack user create --domain default --password-prompt cinder
# source admin-openrc.sh
# openstack user create --domain default --password-prompt cinder
User Password:
Repeat User Password:

增加block storage - 安装和配置【控制节点】
安装包yum install -y openstack-cinder python-cinderclient
编辑配置文件vim /etc/cinder/cinder.conf//更改或增加
connection = mysql://cinder:cinder@controller/cinder
rpc_backend = rabbit
auth_strategy = keystone
my_ip = 192.168.100.20
verbose = True
auth_uri = http://controller:5000
auth_url = http://controller:35357
auth_plugin = password
project_domain_id = default
user_domain_id = default
project_name = service
username = cinder
password = cinderpasswd
rabbit_host = controller
rabbit_userid = openstack
rabbit_password = openstackpasswd
lock_path = /var/lib/cinder/tmp
同步数据su -s /bin/sh -c "cinder-manage db sync" cinder
配置compute使用块存储
vi /etc/nova/nova.conf #增加以下配置
os_region_name=RegionOne
启动服务
systemctl restart openstack-nova-api.service
systemctl enable openstack-cinder-api.service openstack-cinder-scheduler.service
systemctl start openstack-cinder-api.service openstack-cinder-scheduler.service
# systemctl restart openstack-nova-api.service
# systemctl enable openstack-cinder-api.service openstack-cinder-scheduler.service
Created symlink from /etc/systemd/system/multi-user.target.wants/openstack-cinder-api.service to /usr/lib/systemd/system/openstack-cinder-api.service.

# systemctl start openstack-cinder-api.service openstack-cinder-scheduler.service
#
增加block storage - 配置storage节点【计算节点】
我们理应需要再准备一台单独的机器来做storage服务的，但是为了节省资源，我们就那compute节点和storage节点共用。这里需要为compute（storage）节点再增加一块磁盘（/dev/sdb）作为存储磁盘。
安装lvm
yum install -y lvm2
启动服务
systemctl enable lvm2-lvmetad.service
systemctl start lvm2-lvmetad.service
创建物理卷 pvcreate /dev/sdb
创建卷组vgcreate cinder-volumes /dev/sdb
# pvcreate /dev/sdb
Physical volume "/dev/sdb" successfully created
# vgcreate cinder-volumes /dev/sdb
Volume group "cinder-volumes" successfully created
# 编辑配置文件 vi/etc/lvm/lvm.conf
devices {
filter = [ "a/sdb/", "r/.*/"]
说明： 如果还有第三块磁盘，应该再加上
filter = [ "a/sda/", "a/sdb/", "r/.*/"]
增加block storage - 配置storage节点 (compute)
安装包yum install -yopenstack-cinder targetcli python-oslo-policy
编辑配置文件 vi /etc/cinder/cinder.conf
rpc_backend = rabbit
auth_strategy = keystone
my_ip = 192.168.100.21
enabled_backends = lvm
glance_host = controller
verbose = True
connection = mysql://cinder:cinder@controller/cinder
rabbit_host = controller
rabbit_userid = openstack
rabbit_password = openstackpasswd
auth_uri = http://controller:5000
auth_url = http://controller:35357
auth_plugin = password
project_domain_id = default
user_domain_id = default
project_name = service
username = cinder
password = cinderpasswd
volume_driver = cinder.volume.drivers.lvm.LVMVolumeDriver
volume_group = cinder-volumes
iscsi_protocol = iscsi
iscsi_helper = lioadm
lock_path = /var/lib/cinder/tmp
增加block storage - 启动和验证
启动服务 (compute)
systemctl enable openstack-cinder-volume.service target.service
systemctl start openstack-cinder-volume.service target.service
验证操作(controller)
1. 执行初始化脚本
source admin-openrc.sh
2. 列出服务
cinder service-list
# source admin-openrc.sh
# cinder service-list
+------------------+-------------+------+---------+-------+----------------------------+-----------------+
| Binary | Host | Zone |Status | State | Updated_at | Disabled Reason |
+------------------+-------------+------+---------+-------+----------------------------+-----------------+

至此所有节点基本安装完成可以创建实例
