#centos7手动部署openstack的T版本
1.基础环境准备
#模板需要nat网卡和仅主机网卡。并配置内核参数net.ifnames=0 biosdevname=0。时间同步计划任务自动同步阿里云的时间服务器。关闭防火墙和selinux。
#注意：VMwareworkstation开启cpu的虚拟化功能，否则cpu不支持虚拟化后期配置nova需要配置virt-type=qemu进行模拟，性能非常差。此配置后面就是使用的qemu，走了弯路。

######Public：共有网络 比如：172.16.0.0/16
######这里使用vip的域名来连接控制节点的5000端口实现高可用，需要在haproxy中加入一个listen语句块实现转发。多个keystone服务可以写多个server。重启haproxy，并ss -tnl确认监听了5000端口

#neutron服务安装官方参考文档
https://docs.openstack.org/neutron/train/install/install-rdo.html
#有两种网络类型可选：
#提供者网络：虚拟机桥接到物理机，并且虚拟机必须和物理机在一个网络范围内。
网络选项 1：提供商网络
提供者网络选项以最简单的方式部署 OpenStack 网络服务，主要包括第 2 层（桥接/交换）服务和网络 VLAN 分段。本质上，它将虚拟网络连接到物理网络，并依赖物理网络基础设施提供第 3 层（路由）服务。此外，DHCP<动态主机配置协议 (DHCP) 服务向实例提供 IP 地址信息。
警告：此选项不支持自助服务（专用）网络、第 3 层（路由）服务和高级服务，例如防火墙即服务 (FWaaS)。如果您需要这些功能，请考虑以下自助服务网络选项。
#自服务网络：可以自己创建网络，最终会通过虚拟路由器连接外网。
自助服务网络选项通过第 3 层（路由）服务增强了提供商网络选项，这些服务支持使用虚拟可扩展 LAN (VXLAN) 等覆盖分段方法的自助服务网络。本质上，它使用网络地址转换 (NAT) 将虚拟网络路由到物理网络。此外，此选项为 FWaaS 等高级服务奠定了基础。
OpenStack 用户可以在不了解数据网络底层基础设施的情况下创建虚拟网络。如果相应地配置了第 2 层插件，这也可以包括 VLAN 网络。
#私有云一般使用提供者网络，公有云使用自服务网络。这里仅演示提供者网络,自服务网络请参考官网文档

#您可以使用选项 1 和 2 表示的两种架构之一来部署网络服务。这里仅演示提供者网络,自服务网络请参考官网文档
#选项 1 部署了最简单的架构，该架构仅支持将实例附加到提供者（外部）网络。没有自助服务（专用）网络、路由器或浮动 IP 地址。只有该admin或其他特权用户可以管理提供商网络。
#选项 2 通过支持将实例附加到自助服务网络的第 3 层服务来扩充选项 1。该demo或其他非特权用户可以管理自助服务网络，包括提供自助服务和提供商网络之间的连接的路由器。此外，浮动 IP 地址使用来自外部网络（如 Internet）的自助服务网络提供与实例的连接.自助服务网络通常使用覆盖网络。VXLAN 等覆盖网络协议包括额外的标头，这些标头会增加开销并减少可用于有效负载或用户数据的空间。在不了解虚拟网络基础架构的情况下，实例会尝试使用 1500 字节的默认以太网最大传输单元 (MTU) 发送数据包。网络服务通过 DHCP 自动为实例提供正确的 MTU 值。但是，某些云映像不使用 DHCP 或忽略 DHCP MTU 选项，并且需要使用元数据或脚本进行配置。

网络服务初始化脚本需要一个 /etc/neutron/plugin.ini指向 ML2 插件配置文件的符号链接，/etc/neutron/plugins/ml2/ml2_conf.ini. 如果此符号链接不存在，请使用以下命令创建它：
[root@openstack-controller1 ~]# ln -s /etc/neutron/plugins/ml2/ml2_conf.ini /etc/neutron/plugin.ini
#填充数据库：
[root@openstack-controller1 ~]# 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
#重启nova API 服务：
[root@openstack-controller1 ~]# systemctl restart openstack-nova-api.service
#启动网络服务并将它们配置为在系统启动时启动。
[root@openstack-controller1 ~]# systemctl enable neutron-server.service neutron-linuxbridge-agent.service neutron-dhcp-agent.service neutron-metadata-agent.service
[root@openstack-controller1 ~]# systemctl start neutron-server.service neutron-linuxbridge-agent.service neutron-dhcp-agent.service neutron-metadata-agent.service
#在compute1节点配置
安装组件
[root@openstack-compute1 ~]# yum install openstack-neutron-linuxbridge ebtables ipset -y
配置通用组件
Networking 通用组件配置包括认证机制、消息队列和插件。
编辑/etc/neutron/neutron.conf文件并完成以下操作：
[root@openstack-compute1 ~]# vim /etc/neutron/neutron.conf
在该[database]部分中，注释掉任何connection选项，因为计算节点不直接访问数据库。
在该[DEFAULT]部分中，配置RabbitMQ 消息队列访问：
[DEFAULT]
transport_url = rabbit://openstack:openstack123@openstack-vip.tan.local
在[DEFAULT]和[keystone_authtoken]部分中，配置身份服务访问：
[DEFAULT]
auth_strategy = keystone
[keystone_authtoken]
www_authenticate_uri = http://openstack-vip.tan.local:5000
auth_url = http://openstack-vip.tan.local:5000
memcached_servers = openstack-vip.tan.local:11211
auth_type = password
project_domain_name = default
user_domain_name = default
project_name = service
username = neutron
password = neutron
在该[oslo_concurrency]部分中，配置锁定路径：
[oslo_concurrency]
lock_path = /var/lib/neutron/tmp
选择您为控制器节点选择的相同网络选项以配置特定于它的服务。之后，返回此处并继续 配置计算服务以使用网络服务。
网络选项 1：提供商网络
配置 Linux 网桥代理
Linux 桥接代理为实例构建第 2 层（桥接和交换）虚拟网络基础架构并处理安全组。
编辑/etc/neutron/plugins/ml2/linuxbridge_agent.ini文件并完成以下操作：
[root@openstack-compute1 ~]# vim /etc/neutron/plugins/ml2/linuxbridge_agent.ini
在该[linux_bridge]部分中，将提供者虚拟网络映射到提供者物理网络接口：
[linux_bridge]
physical_interface_mappings = external:eth1
####绑定本机的网卡，如果和controller不一样做了bind0就写bind0
替换PROVIDER_INTERFACE_NAME为底层提供者物理网络接口的名称
在该[vxlan]部分中，禁用 VXLAN 覆盖网络：
[vxlan]
enable_vxlan = false
在该[securitygroup]部分中，启用安全组并配置 Linux 网桥 iptables 防火墙驱动程序：
[securitygroup]
enable_security_group = true
firewall_driver = neutron.agent.linux.iptables_firewall.IptablesFirewallDriver
#sysctl通过验证以下所有值都设置为1，确保您的 Linux 操作系统内核支持网桥过滤器：
[root@openstack-compute1 ~]# vim /etc/sysctl.conf
net.bridge.bridge-nf-call-iptables = 1
net.bridge.bridge-nf-call-ip6tables = 1
[root@openstack-compute1 ~]# modprobe br_netfilter
[root@openstack-compute1 ~]# sysctl -p
net.bridge.bridge-nf-call-iptables = 1
net.bridge.bridge-nf-call-ip6tables = 1
#要启用网络桥接支持，通常br_netfilter需要加载内核模块。有关启用此模块的更多详细信息，请查看您的操作系统文档。
#配置计算服务以使用网络服务
编辑/etc/nova/nova.conf文件并完成以下操作：
[root@openstack-compute1 ~]# vim /etc/nova/nova.conf
在该[neutron]部分中，配置访问参数：
[neutron]
# ...
auth_url = http://openstack-vip.tan.local:5000
auth_type = password
project_domain_name = default
user_domain_name = default
region_name = RegionOne
project_name = service
username = neutron
password = neutron
#完成安装
#重启计算服务：
[root@openstack-compute1 ~]# systemctl restart openstack-nova-compute.service
#启动 Linux 网桥代理并将其配置为在系统引导时启动：
[root@openstack-compute1 ~]# 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.
[root@openstack-compute1 ~]# systemctl start neutron-linuxbridge-agent.service

10.dashboard简介及安装
#dashboard服务安装官方参考文档
https://docs.openstack.org/horizon/train/install/install-rdo.html
本节介绍如何在控制器节点上安装和配置仪表板。
仪表板所需的唯一核心服务是身份服务。您可以将仪表板与其他服务结合使用，例如图像服务、计算和网络。您还可以在具有独立服务（如对象存储）的环境中使用仪表板。
安装和配置组件
安装软件包：
[root@openstack-controller1 ~]# yum install openstack-dashboard -y
编辑 /etc/openstack-dashboard/local_settings 文件并完成以下操作：
[root@openstack-controller1 ~]#vim /etc/openstack-dashboard/local_settings
配置仪表板以在controller节点上使用 OpenStack 服务 ：
OPENSTACK_HOST = "10.0.0.101"
允许您的主机访问仪表板：
ALLOWED_HOSTS = ['10.0.0.101', 'openstack-vip.tan.local']
笔记:ALLOWED_HOSTS 也可以是 ['*'] 以接受所有主机。这可能对开发工作有用，但可能不安全，不应在生产中使用。有关详细信息，请参阅 https://docs.djangoproject.com/en/dev/ref/settings/#allowed-hosts 。
配置memcached会话存储服务：
SESSION_ENGINE = 'django.contrib.sessions.backends.cache'
CACHES = {
'default': {
'BACKEND': 'django.core.cache.backends.memcached.MemcachedCache',
'LOCATION': 'openstack-vip.tan.local:11211',
}
}
启用身份 API 版本 3：
OPENSTACK_KEYSTONE_URL = "http://%s:5000/v3" % OPENSTACK_HOST
启用对域的支持：
OPENSTACK_KEYSTONE_MULTIDOMAIN_SUPPORT = True
配置 API 版本：
OPENSTACK_API_VERSIONS = {
"identity": 3,
"image": 2,
"volume": 3,
}
配置Default为您通过仪表板创建的用户的默认域：
OPENSTACK_KEYSTONE_DEFAULT_DOMAIN = "Default"
配置user为您通过仪表板创建的用户的默认角色：
OPENSTACK_KEYSTONE_DEFAULT_ROLE = "user"
如果您选择网络选项 1，请禁用对第 3 层网络服务的支持：
OPENSTACK_NEUTRON_NETWORK = {
...
'enable_router': False,
'enable_quotas': False,
'enable_distributed_router': False,
'enable_ha_router': False,
'enable_lb': False,
'enable_firewall': False,
'enable_vpn': False,
'enable_fip_topology_check': False,
}
（可选）配置时区：
TIME_ZONE = "Asia/Shanghai"
替换TIME_ZONE为适当的时区标识符。有关详细信息，请参阅时区列表。
#在/etc/openstack-dashboard/local_settings 文件中添加一行 WEBROOT = '/dashboard'
#在/etc/httpd/conf.d/openstack-dashboard.conf如果不包括，则添加以下行 。
[root@openstack-controller1 ~]# vim /etc/httpd/conf.d/openstack-dashboard.conf
WSGIApplicationGroup %{GLOBAL}
########在105 haproxy节点添加一个listen
[root@openstack-ha1 ~]# vim /etc/haproxy/haproxy.cfg
listen openstack-dashboard-80
bind 10.0.0.188:80
mode tcp
server 10.0.0.101 10.0.0.101:80 check inter 3s fall 3 rise 5
[root@openstack-ha1 ~]# systemctl restart haproxy && ss -tnl |grep 80
LISTEN 0 128 10.0.0.188:6080 *:*
LISTEN 0 128 10.0.0.188:80 *:*
完成安装
#重启 Web 服务器和会话存储服务：
[root@openstack-controller1 ~]# systemctl restart httpd
#然后就使用http://10.0.0.101/dashboard访问网页了，可以使用admin/admin，或者myuser用户登录本文章为转载内容，我们尊重原作者对文章享有的著作权。如有内容错误或侵权问题，欢迎原作者联系我们进行内容更正或删除文章。
