Centos7.3 部署openstack ocata版本

Centos7.3 部署openstack ocata版本

openstack 介绍

OpenStack是一个由NASA（美国国家航空航天局）和Rackspace合作研发并发起的，以Apache许可证授权的自由软件和开放源代码项目。
OpenStack是一个开源的云计算管理平台项目，由几个主要的组件组合起来完成具体工作。OpenStack支持几乎所有类型的云环境，项目目标是提供实施简单、可大规模扩展、丰富、标准统一的云计算管理平台。OpenStack通过各种互补的服务提供了基础设施即服务（IaaS）的解决方案，每个服务提供API以进行集成。

OpenStack是一个旨在为公共及私有云的建设与管理提供软件的开源项目。它的社区拥有超过130家企业及1350位开发者，这些机构与个人都将OpenStack作为基础设施即服务（IaaS）资源的通用前端。OpenStack项目的首要任务是简化云的部署过程并为其带来良好的可扩展性。本文希望通过提供必要的指导信息，帮助大家利用OpenStack前端来设置及管理自己的公共云或私有云。

OpenStack云计算平台，帮助服务商和企业内部实现类似于 Amazon EC2 和 S3 的云基础架构服务(Infrastructure as a Service, IaaS)。OpenStack 包含两个主要模块：Nova 和 Swift，前者是 NASA 开发的虚拟服务器部署和业务计算模块；后者是 Rackspace开发的分布式云存储模块，两者可以一起用，也可以分开单独用。OpenStack除了有 Rackspace 和 NASA 的大力支持外，还有包括 Dell、Citrix、 Cisco、 Canonical等重量级公司的贡献和支持，发展速度非常快，有取代另一个业界领先开源云平台 Eucalyptus 的态势。

搭建openstack

3.1 安装keystone 组件介绍

Keystone功能：

1.用户与认证: 用户权限与用户行为跟踪

2.服务目录：提供一个服务目录、包括所有服务项与相关API的端点

Keystone名词：

User： 用户

Tenant： 租户/项目

Token： 令牌

Role： 角色

Service： 服务

Endpoint： 端点

3.2 安装keystone 组件（node2 主控制节点操作）

安装openstack最新的源： 　　　　

yum install centos-release-openstack-ocata 　　　　

yum install https://rdoproject.org/repos/rdo-release.rpm 　　　　

yum upgrade (在主机上升级包）

yum install python-openstackclient （安装opentack必须的插件）

yum install openstack-selinux （可选则安装这个插件，我直接关闭了selinux，因为不熟，对后续不会有影响）

[root@linux-node1 home]# yum install openstack-keystone httpd mod_wsgi

3.2.1修改配置文件

vim /etc/keystone/keystone.conf
[database]
connection = mysql://keystone:[email protected]/keystone 
[token]
provider = fernet

3.2.2同步数据库

su -s /bin/sh -c "keystone-manage db_sync" keystone
###为什么需要su 一下呢？因为在写日志的时候文件是放在/var/log/keystone 
这个下面如果是root用户执行的话。那么写日志的时候就会写不进去。
验证一下是否成功。进入数据库查看有没有表的建立。

 MariaDB [keystone]> show tables;

+------------------------+
| Tables_in_keystone     |
初始化
# keystone-manage fernet_setup --keystone-user keystone --keystone-group keystone
# keystone-manage credential_setup --keystone-user keystone --keystone-group keystone



引导身份信息
keystone-manage bootstrap --bootstrap-password ADMIN_PASS \
  --bootstrap-admin-url http://linux-node2:35357/v3/ \
  --bootstrap-internal-url http://linux-node2:5000/v3/ \
  --bootstrap-public-url http://controller:5000/v3/ \
  --bootstrap-region-id RegionOne

3.2.3配置memcache的配置 （/etc/sysconfig/memcached）

vim /etc/sysconfig/memcached
OPTIONS="-l 127.0.0.1,::1,192.168.57.141"

3.2.4启动memcache

[root@linux-node2 ~]# systemctl start memcached.service
 [root@linux-node2 ~]# netstat -nltp|grep 121
tcp        0      0 0.0.0.0:11211           0.0.0.0:*               LISTEN      20054/memcached     
tcp6       0      0 :::11211                :::*                    LISTEN      20054/memcached

3.2.5设置apache

ln -s /usr/share/keystone/wsgi-keystone.conf /etc/httpd/conf.d/
3.2.6修改主apache的主配置文件
vim /etc/httpd/conf/httpd.conf
配置一下Servername
ServerName 192.168.57.138:80

3.2.7启动apache

systemctl enable httpd.service
systemctl start httpd.service

3.2.8检查一下是否启动成功了

[root@linux-node2 conf.d]# netstat -nltp|grep httpd
tcp6       0      0 :::80                   :::*                    LISTEN      20253/httpd         
tcp6       0      0 :::35357                :::*                    LISTEN      20253/httpd         
tcp6       0      0 :::5000                 :::*                    LISTEN      20253/httpd         
[root@linux-node2 conf.d]#

3.3 keystone 用户权限

3.3.1 设置环境变量

$ export OS_USERNAME=admin
$ export OS_PASSWORD=ADMIN_PASS
$ export OS_PROJECT_NAME=admin
$ export OS_USER_DOMAIN_NAME=Default
$ export OS_PROJECT_DOMAIN_NAME=Default
$ export OS_AUTH_URL=http://linux-node2:35357/v3
$ export OS_IDENTITY_API_VERSION=3

3.3.2创建域、项目、用户和角色

创建服务
[root@linux-node2 ~]# openstack project create --domain default --description "Service Project" service
创建demo项目
 [root@linux-node2 ~]# openstack project create --domain default \
> --description "Demo Project" demo
设置demo密码
[root@linux-node2 ~]# openstack user create --domain default \
> --password-prompt demo
创建用户组
 [root@linux-node2 ~]# openstack role create user
加入用户组
 [root@linux-node2 ~]# openstack role add --project demo --user demo user

3.3.3验证操作

1.出于安全原因，请禁用临时身份验证令牌机制：
编辑/etc/keystone/keystone-paste.ini 文件并删除admin_token_auth从 [pipeline:public_api]，[pipeline:admin_api]和[pipeline:api_v3]段。

2、取消设置临时 变量OS_AUTH_URL和OS_PASSWORD环境变量：
[root@linux-node2 ~]#  unset OS_AUTH_URL OS_PASSWORD
3、作为admin 、请求身份验证令牌
$ openstack --os-auth-url http://linux-node2:35357/v3 \
  --os-project-domain-name default --os-user-domain-name default \
  --os-project-name admin --os-username admin token issue

网络节点一（node2 主控制节点操作）

7.1 设置mysql

$ mysql -u root –p
MariaDB [（none）] CREATE DATABASE neutron;
MariaDB [(none)]> GRANT ALL PRIVILEGES ON neutron.* TO 'neutron'@'localhost' \
  IDENTIFIED BY 'neutron';
MariaDB [(none)]> GRANT ALL PRIVILEGES ON neutron.* TO 'neutron'@'%' \
  IDENTIFIED BY 'neutron';

7.2创建服务凭据

在admin的环境下
$ . admin-openrc
$ openstack user create --domain default --password-prompt neutron

User Password: neutron  #密码
Repeat User Password: neutron  #密码
+---------------------+----------------------------------+
| Field               | Value                            |
+---------------------+----------------------------------+
| domain_id           | default                          |
| enabled             | True                             |
| id                  | fdb0f541e28141719b6a43c8944bf1fb |

| options             | {}                               |
| password_expires_at | None                             |
+---------------------+----------------------------------+

加入到admin组
$ openstack role add --project service --user neutron admin
创建neutron 服务实体
$ openstack service create --name neutron \
  --description "OpenStack Networking" network
创建neutron API
$ openstack endpoint create --region RegionOne \
  network public http://linux-node2:9696
$ openstack endpoint create --region RegionOne \
  network internal http://linux-node2:9696
$ openstack endpoint create --region RegionOne \
  network admin http://linux-node2:9696

7.3配置网络选项（这里我选用的是网络1 的配置）

您可以使用选项1和2所代表的两种体系结构之一来部署网络服务。
选项1部署了最简单的架构，只支持将实例连接到提供者（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admin或其他特权用户才能管理提供商网络。
选项2增加了选项1，其中第三层服务支持将实例附加到自助服务网络。这个demo或其他非特权用户可以管理自助服务网络，包括在自助服务和提供商网络之间提供连接的路由器。此外，浮动IP地址还提供与使用来自外部网络（如Internet）的自助服务网络的实例的连接。
自助服务网络通常使用覆盖网络。覆盖网络协议（如VXLAN）包含额外的标头，这些标头会增加开销并减少有效负载或用户数据的可用空间。在不了解虚拟网络基础架构的情况下，实例将尝试使用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，某些云图像不使用DHCP或忽略DHCP MTU选项并需要使用元数据或脚本进行配置。

7.4 安装网络openstack-neutron

# yum install openstack-neutron openstack-neutron-ml2 \
  openstack-neutron-linuxbridge ebtables

7.5 编辑/etc/neutron/neutron.conf

auth_url = http://linux-node2:35357
memcached_servers = linux-node2:11211
auth_type = password
project_domain_name = default
user_domain_name = default
project_name = service
username = neutron
password = neutron  ######这个密码是上面设置的密码
[nova]
# ...
auth_url = http://controller:35357
auth_type = password
project_domain_name = default
user_domain_name = default
region_name = RegionOne
project_name = service
username = nova
password = nova  ####注意这个是nova设置的密码
[oslo_concurrency]
# ...
lock_path = /var/lib/neutron/tmp

7.6配置模块化层2（ML2）插件（/etc/neutron/plugins/ml2/ml2_conf.ini）

编辑配置文件设置如下：
[ml2]
type_drivers = flat,vlan
tenant_network_types =
mechanism_drivers = linuxbridge
[ml2_type_flat]
flat_networks = provider
[securitygroup]
enable_ipset = true

7.7配置Linux网桥代理（/etc/neutron/plugins/ml2/linuxbridge_agent.ini）

编辑配置文件设置如下：
[linux_bridge]
physical_interface_mappings = provider:eth1  ####这个是为底层实现网络的网络接口（我这里用了eth1）
[vxlan]
enable_vxlan = false
[securitygroup]
# ...
enable_security_group = true
firewall_driver = neutron.agent.linux.iptables_firewall.IptablesFirewallDriver

7.8配置DHCP代理（/etc/neutron/dhcp_agent.ini）

[DEFAULT] 
＃... 
interface_driver  =  linuxbridge 
dhcp_driver  =  neutron.agent.linux.dhcp.Dnsmasq 
enable_isolated_metadata  =  true

7.9配置计算服务以使用网络服务（/etc/nova/nova.conf）

在该[neutron]部分中，配置访问参数，启用元数据代理并配置密钥：
[neutron] 
＃... 
url  =  http：//linux-node2：9696 
auth_url  =  http：//linux-node2：35357 
auth_type  =  password 
project_domain_name  =  default 
user_domain_name  =  default 
region_name  =  RegionOne 
project_name  =  service 
username  =  neutron 
password  = neutron      ###在身份识别服务中为用户选择的密码。
service_metadata_proxy  =  true 
metadata_proxy_shared_secret  =  neutron     #  #为元数据代理选择的密码。
创建扩展链接
# ln -s /etc/neutron/plugins/ml2/ml2_conf.ini /etc/neutron/plugin.ini

7.10同步数据库

# 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

7.11 启动服务

重新启动计算API服务：
# systemctl restart openstack-nova-api.service
启动网络服务并将其配置为在系统引导时启动。
# systemctl enable neutron-server.service \
  neutron-linuxbridge-agent.service neutron-dhcp-agent.service \
  neutron-metadata-agent.service
# systemctl start neutron-server.service \
  neutron-linuxbridge-agent.service neutron-dhcp-agent.service \
  neutron-metadata-agent.service

网络节点二、（node1 计算节点操作）

8.1 安装openstack-neutron

yum install openstack-neutron-linuxbridge ebtables ipset

8.2配置通用组件（/etc/neutron/neutron.conf）

修改如下配置文件：
