OpenStack Mitaka(openstack最新版安装)安装
前言:
  openstack的部署非常简单,简单的前提建立在扎实的理论功底,本人一直觉得,玩技术一定是理论指导实践,网上遍布个种搭建方法都可以实现一个基本的私有云环境,但是诸位可曾发现,很多配置都是重复的,为何重复?到底什么位置该不该配?具体配置什么参数?很多作者本人都搞不清楚,今天本人就是要在这里正本清源(因为你不理解所以你会有冗余的配置,说白了,啥配置啥意思你根本没闹明白)。
如有不解可邮件联系我:egonlin4573@gmail.com

介绍:本次案列为基本的三节点部署,集群案列后期有时间再整理
一:网络(本次实验没有做Cinder节点):
1.管理网络:172.16.209.0/24
2.数据网络:1.1.1.0/24
二:操作系统:Centos linux release 7.2.1511 (Core)

三:内核:3.10.0-327.el7.x86_64

四:openstack版本mitaka

效果图:


OpenStack mitaka部署
约定:
0.以下配置是在原有配置文件上找相关项进行修改或添加
1.在修改配置的时候,切勿在某条配置后加上注释,可以在配置的上面或者下面加注释
2.相关配置一定是在标题后追加,不要在原有注释的基础上修改


PART1:环境准备
一:
1:每台机器设置固定ip,每台机器添加hosts文件解析,为每台机器设置主机名,关闭firewalld,selinux
/etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
172.16.209.115 controller01
172.16.209.117 compute01
172.16.209.119 network02

其中 network02三块网卡,IT论坛的两块

2.每台机器配置yum源,可不配置,,使用默认的CentOS repo
[mitaka]
name=mitaka repo
baseurl=http://172.16.209.100/mitaka-rpms/
enabled=1
gpgcheck=0

3.每台机器
yum makecache && yum install vim net-tools -y&& yum update -y

4.时间服务部署

所有节点:
yum install chrony -y
控制节点:
修改配置:
/etc/chrony.conf
server ntp.staging.kycloud.lan iburst
allow 管理网络网段ip/24
启服务:
systemctl enable chronyd.service
systemctl start chronyd.service


其余节点:
修改配置:
/etc/chrony.conf
server 控制节点ip iburst
启服务
systemctl enable chronyd.service
systemctl start chronyd.service



时区不是Asia/Shanghai需要改时区:
# timedatectl set-local-rtc 1 # 将硬件时钟调整为与本地时钟一致, 0 为设置为 UTC 时间
# timedatectl set-timezone Asia/Shanghai # 设置系统时区为上海
其实不考虑各个发行版的差异化, 从更底层出发的话, 修改时间时区比想象中要简单:
# cp /usr/share/zoneinfo/Asia/Shanghai /etc/localtime



验证:
每台机器执行:
chronyc sources
在S那一列包含*号,代表同步成功(可能需要花费几分钟去同步,时间务必同步)

二:获取软件包
如果使用自定义源,那么下列centos和RedHat的操作可以省略
#在所有节点执行
centos:
yum install yum-plugin-priorities -y #防止自动更新
yum install centos-release-openstack-mitaka -y #如果不使用我的自定义yum那么请执行这一步
redhat:
yum install yum-plugin-priorities -y
红帽系统请去掉epel源

#在所有节点执行

yum upgrade
yum install Python-openstackclient -y
yum install openstack-selinux -y

三:部署mariadb数据库
控制节点:
yum install mariadb mariadb-server python2-PyMySQL -y

编辑:
/etc/my.cnf.d/openstack.cnf

[mysqld]
bind-address = 控制节点管理网络ip
default-storage-engine = innodb
innodb_file_per_table
max_connections = 4096
collation-server = utf8_general_ci
character-set-server = utf8

启服务:
systemctl enable mariadb.service
systemctl start mariadb.service
mysql_secure_installation


四:为Telemetry 服务部署MongoDB
控制节点:
yum install mongodb-server mongodb -y

编辑:/etc/mongod.conf
bind_ip = 控制节点管理网络ip
smallfiles = true

启动服务:
systemctl enable mongod.service
systemctl start mongod.service


五:部署消息队列rabbitmq
控制节点:
yum install rabbitmq-server -y

启动服务:
systemctl enable rabbitmq-server.service
systemctl start rabbitmq-server.service

新建rabbitmq用户密码:
rabbitmqctl add_user openstack che001

rabbitmqctl  delete_user guest

为新建的用户openstack设定权限:
rabbitmqctl set_permissions openstack ".*" ".*" ".*"

启动管理WEB
rabbitmq-plugins enable rabbitmq_management
(验证方式:http://172.16.209.104:15672/ 用户penstack 密码:che001)

六:部署memcached缓存(为keystone服务缓存tokens)
控制节点:
yum install memcached python-memcached -y
cat /etc/sysconfig/memcached
[url=][/url]
PORT="11211"USER="memcached"MAXCONN="10240"CACHESIZE="64"#OPTIONS="-l 127.0.0.1,::1"OPTIONS="-l 0.0.0.0"[url=][/url]


启动服务:
systemctl enable memcached.service
systemctl start memcached.service

PART2:认证服务keystone部署

一:安装和配置服务
1.建库建用户
mysql -u root -p
CREATE DATABASE keystone;
GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'localhost' \
  IDENTIFIED BY 'che001';
GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'%' \
  IDENTIFIED BY 'che001';
flush privileges;

2.yum install openstack-keystone httpd mod_wsgi -y

3.编辑/etc/keystone/keystone.conf

[DEFAULT]
admin_token = che001
#建议用命令制作tokenpenssl rand -hex 10
#这里的作用主要是先手动指定admin_token,为了部署keystone,因为keystone没部署,认证环节还不能工作,等keystone部署好,会把手动指定admin_token认证方式去掉

[database]
connection = mysql+pymysql://keystone:che001@controller01/keystone

[token]
provider = fernet
#Token Provider:UUID, PKI, PKIZ, or Fernet #http://blog.csdn.net/miss_yang_cloud/article/details/49633719


4.同步修改到数据库
su -s /bin/sh -c "keystone-manage db_sync" keystone

5.初始化fernet keys
keystone-manage fernet_setup --keystone-user keystone --keystone-group keystone

6.配置apache服务
编辑:/etc/httpd/conf/httpd.conf
ServerName controller01

编辑:/etc/httpd/conf.d/wsgi-keystone.conf
新增配置
Listen 5000
Listen 35357

<VirtualHost *:5000>
    WSGIDaemonProcess keystone-public processes=5 threads=1 user=keystone group=keystone display-name=%{GROUP}
    WSGIProcessGroup keystone-public
    WSGIScriptAlias / /usr/bin/keystone-wsgi-public
    WSGIapplicationGroup %{GLOBAL}
    WSGIPassAuthorization On
    ErrorLogFormat "%{cu}t %M"
    ErrorLog /var/log/httpd/keystone-error.log
    CustomLog /var/log/httpd/keystone-Access.log combined

    <Directory /usr/bin>
        Require all granted
    </Directory>
</VirtualHost>

<VirtualHost *:35357>
    WSGIDaemonProcess keystone-admin processes=5 threads=1 user=keystone group=keystone display-name=%{GROUP}
    WSGIProcessGroup keystone-admin
    WSGIScriptAlias / /usr/bin/keystone-wsgi-admin
    WSGIApplicationGroup %{GLOBAL}
    WSGIPassAuthorization On
    ErrorLogFormat "%{cu}t %M"
    ErrorLog /var/log/httpd/keystone-error.log
    CustomLog /var/log/httpd/keystone-access.log combined

    <Directory /usr/bin>
        Require all granted
    </Directory>
</VirtualHost>

7.启动服务:
systemctl enable httpd.service
systemctl start httpd.service

二:创建服务实体和访问端点

1.实现配置管理员环境变量,用于获取后面创建的权限
export OS_TOKEN=che001
#要与前面的/etc/keystone/keystone.conf中的admin_token相同
export OS_URL=http://controller01:35357/v3
export OS_IDENTITY_API_VERSION=3

2.基于上一步给的权限,创建认证服务实体(目录服务)
openstack service create --name keystone --description "OpenStack Identity" identity
#如遇到报500错误,ArgsAlreadyParsedError: arguments already parsed: cannot register CLI option,可把--description "OpenStack Identity"去掉
3.基于上一步建立的服务实体,创建访问该实体的三个api端点

openstack endpoint create --region RegionOne \
  identity public http://controller01:5000/v3

openstack endpoint create --region RegionOne \
  identity internal http://controller01:5000/v3

openstack endpoint create --region RegionOne \
  identity admin http://controller01:35357/v3

三:创建域,租户,用户,角色,把四个元素关联到一起
建立一个公共的域名
openstack domain create --description "Default Domain" default

管理员:admin
openstack project create --domain default \
  --description "Admin Project" admin

openstack user create --domain default \
  --password-prompt admin

openstack role create admin

openstack role add --project admin --user admin admin

普通用户:demo
openstack project create --domain default \
  --description "Demo Project" demo

openstack user create --domain default \
  --password-prompt demo

openstack role create user

openstack role add --project demo --user demo user

为后续的服务创建统一租户service
解释:后面每搭建一个新的服务都需要在keystone中执行四种操作:1.建租户 2.建用户 3.建角色 4.做关联
后面所有的服务公用一个租户service,都是管理员角色admin,所以实际上后续的服务安装关于keysotne
的操作只剩2,4
openstack project create --domain default \
  --description "Service Project" service


四:验证操作:
编辑:/etc/keystone/keystone-paste.ini
在[pipeline:public_api], [pipeline:admin_api], and [pipeline:api_v3] 三个地方
移走:admin_token_auth
keystone部署好后,可以使用用户名密码进行验证产生token了,不需要手动指定admin_token了

unset OS_TOKEN OS_URL

openstack --os-auth-url http://controller01:35357/v3 \
  --os-project-domain-name default --os-user-domain-name default \
  --os-project-name admin --os-username admin token issue
Password: (输入openstack user create --domain default --password-prompt admin为admin设置的密码)


五:新建客户端脚本文件

管理员:admin-openrc
export OS_PROJECT_DOMAIN_NAME=default
export OS_USER_DOMAIN_NAME=default
export OS_PROJECT_NAME=admin
export OS_USERNAME=admin
export OS_PASSWORD=che001
export OS_AUTH_URL=http://controller01:35357/v3
export OS_IDENTITY_API_VERSION=3
export OS_IMAGE_API_VERSION=2

普通用户demo:demo-openrc
export OS_PROJECT_DOMAIN_NAME=default
export OS_USER_DOMAIN_NAME=default
export OS_PROJECT_NAME=demo
export OS_USERNAME=demo
export OS_PASSWORD=che001
export OS_AUTH_URL=http://controller01:5000/v3
export OS_IDENTITY_API_VERSION=3
export OS_IMAGE_API_VERSION=2

效果:
source admin-openrc
[root@controller01 ~]# openstack token issue

part3:部署镜像服务
一:安装和配置服务
1.建库建用户
mysql -u root -p
CREATE DATABASE glance;
GRANT ALL PRIVILEGES ON glance.* TO 'glance'@'localhost' \
  IDENTIFIED BY 'che001';
GRANT ALL PRIVILEGES ON glance.* TO 'glance'@'%' \
  IDENTIFIED BY 'che001';
flush privileges;

2.keystone认证操作:
上面提到过:所有后续项目的部署都统一放到一个租户service里,然后需要为每个项目建立用户,建管理员角色,建立关联
. admin-openrc
openstack user create --domain default --password-prompt glance

openstack role add --project service --user glance admin

建立服务实体
openstack service create --name glance \
  --description "OpenStack Image" image

建端点
openstack endpoint create --region RegionOne \
  image public http://controller01:9292


openstack endpoint create --region RegionOne \
  image internal http://controller01:9292

openstack endpoint create --region RegionOne \
  image admin http://controller01:9292

3.安装软件
yum install openstack-glance -y

4.修改配置:
编辑:/etc/glance/glance-api.conf

[database]
#这里的数据库连接配置是用来初始化生成数据库表结构,不配置无法生成数据库表结构
#glance-api不配置database对创建vm无影响,对使用metada有影响
#日志报错:ERROR glance.api.v2.metadef_namespaces
connection = mysql+pymysql://glance:che001@controller01/glance

[keystone_authtoken]
auth_url = http://controller01:5000
memcached_servers = controller01:11211
auth_type = password
project_domain_name = default
user_domain_name = default
project_name = service
username = glance
password = che001

[paste_deploy]
flavor = keystone

[glance_store]
stores = file,http
default_store = file
filesystem_store_datadir = /var/lib/glance/images/

编辑:/etc/glance/glance-registry.conf

[database]
#这里的数据库配置是用来glance-registry检索镜像元数据
connection = mysql+pymysql://glance:che001@controller01/glance


新建目录:
mkdir /var/lib/glance/images/
chown glance. /var/lib/glance/images/

同步数据库:(此处会报一些关于future的问题,自行忽略)
su -s /bin/sh -c "glance-manage db_sync" glance

启动服务:
systemctl enable openstack-glance-api.service \
  openstack-glance-registry.service
systemctl start openstack-glance-api.service \
  openstack-glance-registry.service


二:验证操作:
. admin-openrc

openstack image create "cirros" \

  --password-prompt nova
openstack role add --project service --user nova admin
openstack service create --name nova \
  --description "OpenStack Compute" compute

openstack endpoint create --region RegionOne \
  compute public http://controller01:8774/v2.1/%\(tenant_id\)s

openstack endpoint create --region RegionOne \
  compute internal http://controller01:8774/v2.1/%\(tenant_id\)s

openstack endpoint create --region RegionOne \
  compute admin http://controller01:8774/v2.1/%\(tenant_id\)s


3.安装软件包:
yum install openstack-nova-api openstack-nova-conductor \
  openstack-nova-console openstack-nova-novncproxy \
  openstack-nova-scheduler -y

4.修改配置:
编辑/etc/nova/nova.conf

[DEFAULT]
enabled_apis = oSAPi_compute,metadata
rpc_backend = rabbit
auth_strategy = keystone
#下面的为管理ip
my_ip = 172.16.209.115
use_neutron = True
firewall_driver = nova.virt.firewall.NoopFirewallDriver

[api_database]
connection = mysql+pymysql://nova:che001@controller01/nova_api

[database]
connection = mysql+pymysql://nova:che001@controller01/nova

[oslo_messaging_rabbit]
rabbit_host = controller01
rabbit_userid = openstack
rabbit_password = che001

[keystone_authtoken]
auth_url = http://controller01:5000
memcached_servers = controller01:11211
auth_type = password
project_domain_name = default
user_domain_name = default
project_name = service
username = nova
password = che001


[vnc]
#下面的为管理ip
vncserver_listen = 172.16.209.115
#下面的为管理ip
vncserver_proxyclient_address = 172.16.209.115

[oslo_concurrency]
lock_path = /var/lib/nova/tmp

5.同步数据库:(此处会报一些关于future的问题,自行忽略)
su -s /bin/sh -c "nova-manage api_db sync" nova
su -s /bin/sh -c "nova-manage db sync" nova

6.启动服务
systemctl enable openstack-nova-api.service \
  openstack-nova-consoleauth.service openstack-nova-scheduler.service \
  openstack-nova-conductor.service openstack-nova-novncproxy.service
systemctl start openstack-nova-api.service \

[vnc]
enabled = True
vncserver_listen = 0.0.0.0
#计算节点管理网络ip
vncserver_proxyclient_address = 172.16.209.117
#控制节点管理网络ip

[glance]
api_servers = http://controller01:9292

[oslo_concurrency]
lock_path = /var/lib/nova/tmp

3.如果在不支持虚拟化的机器上部署nova,请确认
egrep -c '(vmx|svm)' /proc/cpuinfo结果为0
则编辑/etc/nova/nova.conf
[libvirt]
virt_type = qemu

4.启动服务
systemctl enable libvirtd.service openstack-nova-compute.service
systemctl start libvirtd.service openstack-nova-compute.service

三:验证
控制节点

  network admin http://controller01:9696


3.安装软件包
yum install openstack-neutron openstack-neutron-ml2 python-neutronclient which  -y

4.配置服务器组件
编辑 /etc/neutron/neutron.conf文件,并完成以下动作:
在[数据库]节中,配置数据库访问:
[DEFAULT]
core_plugin = ml2
service_plugins = router
#下面配置:启用重叠IP地址功能
allow_overlapping_ips = True
rpc_backend = rabbit

[ml2]
type_drivers = flat,vlan,vxlan,gre
tenant_network_types = vxlan
mechanism_drivers = openvswitch,l2population
extension_drivers = port_security

[ml2_type_flat]
flat_networks = provider

[ml2_type_vxlan]
vni_ranges = 1:1000

[securitygroup]
enable_ipset = True


编辑/etc/nova/nova.conf文件:
[neutron]
url = http://controller01:9696
auth_url = http://controller01:5000
auth_type = password
project_domain_name = default
user_domain_name = default
region_name = RegionOne
project_name = service
username = neutron
password = che001
service_metadata_proxy = True

5.创建连接

ln -s /etc/neutron/plugins/ml2/ml2_conf.ini /etc/neutron/plugin.ini

6.同步数据库:(此处会报一些关于future的问题,自行忽略)
su -s /bin/sh -c "neutron-db-manage --config-file /etc/neutron/neutron.conf \
--config-file /etc/neutron/plugins/ml2/ml2_conf.ini upgrade head" neutron

7.重启nova服务
systemctl restart openstack-nova-api.service

8.启动neutron服务
systemctl enable neutron-server.service
systemctl start neutron-server.service

二:网络节点配置

1. 编辑 /etc/sysctl.conf
net.ipv4.ip_forward=1
net.ipv4.conf.all.rp_filter=0
net.ipv4.conf.default.rp_filter=0

2.执行下列命令,立即生效
sysctl -p

3.安装软件包
yum install openstack-neutron openstack-neutron-ml2 openstack-neutron-openvswitch -y

4.配置组件
编辑/etc/neutron/neutron.conf文件
[DEFAULT]
core_plugin = ml2
service_plugins = router
allow_overlapping_ips = True
rpc_backend = rabbit
auth_strategy = keystone


[oslo_messaging_rabbit]
rabbit_host = controller01
rabbit_userid = openstack
rabbit_password = che001

[oslo_concurrency]
lock_path = /var/lib/neutron/tmp

6、编辑 /etc/neutron/plugins/ml2/openvswitch_agent.ini文件:
[ovs]
#下面ip为网络节点数据网络ip
local_ip=1.1.1.119
bridge_mappings=external:br-ex

[agent]
tunnel_types=gre,vxlan
l2_population=True
prevent_arp_spoofing=True


7.配置L3代理。编辑 /etc/neutron/l3_agent.ini文件:
[DEFAULT]
interface_driver=neutron.agent.linux.interface.OVSInterfaceDriver
external_network_bridge=br-ex

8.配置DHCP代理。编辑 /etc/neutron/dhcp_agent.ini文件:

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

9.配置元数据代理。编辑 /etc/neutron/metadata_agent.ini文件:
[DEFAULT]
nova_metadata_ip=controller01
metadata_proxy_shared_secret=che001

10.启动服务

网路节点:
systemctl start neutron-openvswitch-agent.service neutron-l3-agent.service \
neutron-dhcp-agent.service neutron-metadata-agent.service

systemctl enable neutron-openvswitch-agent.service neutron-l3-agent.service \
neutron-dhcp-agent.service neutron-metadata-agent.service



12.建网桥
ovs-vsctl add-br br-ex
ovs-vsctl add-port br-ex eth2
(br-ex、eth2可以不设置IP,有三块网卡不用做以下设置)

注意,如果网卡数量有限,想用网路节点的管理网络网卡作为br-ex绑定的物理网卡
#那么需要将网络节点管理网络网卡ip去掉,建立br-ex的配置文件,ip使用原管理网ip
ovs-vsctl add-br br-ex

NM_CONTROLLED=no #表示修改配置文件后不立即生效,而是在重启/重载network服务时生效

systemctl restart network
ovs-vsctl add-port br-ex eth0


三:计算节点配置
1. 编辑 /etc/sysctl.conf
net.ipv4.conf.all.rp_filter=0
net.ipv4.conf.default.rp_filter=0
net.bridge.bridge-nf-call-iptables=1
net.bridge.bridge-nf-call-ip6tables=1

2.sysctl -p

3.yum install openstack-neutron openstack-neutron-ml2 openstack-neutron-openvswitch -y

4.编辑 /etc/neutron/neutron.conf文件

[DEFAULT]
rpc_backend = rabbit
auth_strategy = keystone


[oslo_messaging_rabbit]
rabbit_host = controller01
rabbit_userid = openstack
rabbit_password = che001

[oslo_concurrency]
lock_path = /var/lib/neutron/tmp

5.编辑 /etc/neutron/plugins/ml2/openvswitch_agent.ini
[ovs]
#下面ip为计算节点数据网络ip
local_ip = 1.1.1.117
#bridge_mappings = vlan:br-vlan
[agent]
tunnel_types = gre,vxlan
l2_population = True
prevent_arp_spoofing = True

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

7.编辑 /etc/nova/nova.conf

[neutron]
url = http://controller01:9696
auth_url = http://controller01:5000
auth_type = password
project_domain_name = default
user_domain_name = default
region_name = RegionOne
project_name = service
username = neutron
password = che001

8.启动服务
systemctl enable neutron-openvswitch-agent.service
systemctl start neutron-openvswitch-agent.service
systemctl restart openstack-nova-compute.service




part6:部署控制面板dashboard
在控制节点
1.安装软件包
yum install openstack-dashboard -y

2.配置/etc/openstack-dashboard/local_settings


OPENSTACK_HOST = "controller01"

ALLOWED_HOSTS = ['*', ]

SESSION_ENGINE = 'django.contrib.sessions.backends.cache'

CACHES = {
    'default': {
         'BACKEND': 'django.core.cache.backends.memcached.MemcachedCache',
         'LOCATION': 'controller01:11211',
    }
}

OPENSTACK_KEYSTONE_URL = "http://%s:5000/v3" % OPENSTACK_HOST

OPENSTACK_KEYSTONE_MULTIDOMAIN_SUPPORT = True

OPENSTACK_API_VERSIONS = {
    "identity": 3,
    "image": 2,
    "volume": 2,
}
OPENSTACK_KEYSTONE_DEFAULT_DOMAIN = "default"
OPENSTACK_KEYSTONE_DEFAULT_ROLE = "user"
TIME_ZONE = "UTC"

3.启动服务
systemctl enable httpd.service memcached.service
systemctl restart httpd.service memcached.service


4.验证;
http://172.16.209.115/dashboard





总结:
  • 与keystone打交道的只有api层,所以不要到处乱配
  • 建主机的时候由nova-compute负责调用各个api,所以不要再控制节点配置啥调用
  • ml2是neutron的core plugin,只需要在控制节点配置
  • 网络节点只需要配置相关的agent
  • 各组件的api除了接收请求外还有很多IT论坛功能,比方说验证请求的合理性,控制节点nova.conf需要配neutron的api、认证,因为nova boot时需要去验证用户提交网络的合理性,控制节点neutron.conf需要配nova的api、认证,因为你删除网络端口时需要通过nova-api去查是否有主机正在使用端口。计算几点nova.conf需要配neutron,因为nova-compute发送请求给neutron-server来创建端口。这里的端口值得是'交换机上的端口'
  • 不明白为啥?或者不懂我在说什么,请好好研究openstack各组件通信机制和主机创建流程,或者来听我的课哦,一般博文都不教真的。


网路故障排查:
网络节点:
[root@network02 ~]# ip netns show
qdhcp-e63ab886-0835-450f-9d88-7ea781636eb8
qdhcp-b25baebb-0a54-4f59-82f3-88374387b1ec
qrouter-ff2ddb48-86f7-4b49-8bf4-0335e8dbaa83
[root@network02 ~]# ip netns exec qrouter-ff2ddb48-86f7-4b49-8bf4-0335e8dbaa83 bash
[root@network02 ~]# ping -c2 www.baidu.com
PING www.a.shifen.com (61.135.169.125) 56(84) bytes of data.

64 bytes from 61.135.169.125: icmp_seq=2 ttl=52 time=25.9 ms


如果无法ping通,那么退出namespace
ovs-vsctl del-br br-ex
ovs-vsctl del-br br-int
ovs-vsctl del-br br-tun
ovs-vsctl add-br br-int
ovs-vsctl add-br br-ex
ovs-vsctl add-port br-ex eth0
systemctl restart neutron-openvswitch-agent.service neutron-l3-agent.service \
neutron-dhcp-agent.service neutron-metadata-agent.service

openStack 基本操作使用
我的环境:

admin用户创建网络
管理员/系统/网络/创建网络


普通用户demo:

创建用户网络

创建路由
创建云主机,创建一个连接demo-net网络的云主机
点击 vm1连接到控制台
输入用户:cirros   密码:cubswin
ping 外部域名或地址,看网络是否通
查看路由

绑定浮动IP,让外部主机能访问到云主机

让外部能访问云主机的ssh
默认情况下,租户的网络之间不能通信,若要通信需要admin把他们的网络设置成共享,通过路由来转发
新建项目ops,并新建两个用户ops1、ops2,新建组opsgroup,把前面两用户加入opsgroup组,项目osp项目中添加opsgroup组
osp1用户登录后,建立网络ops,子网172.16.10.0/24
demo用户建立网络demo-sub2及相关子网172.16.1.0/24
admin新建路由core-router,把 网络 demo-sub2、ops设成成共享,在网络拓扑中,把这两网络连接上core-router

demo用户建立云主机vm2,连接上demo-sub2网络,加入ssh-sec安全组,假设云主机IP为172.16.1.3
osp1用户建立云主机vm_ops1,连接上ops网络,登录vm_ops1云主机,假设DHCP IP为172.16.10.3
ping 172.16.1.3
ssh cirros@172.16.1.3 看是否成功
