计算服务：
安装配置控制节点：
yum install openstack-nova-api openstack-nova-conductor \
openstack-nova-console openstack-nova-novncproxy \
openstack-nova-scheduler
此时，缺少一个包： python-pygments需要自己下载并安装
1、获得 admin 凭证来获取只有管理员能执行的命令的访问权限：
#. admin-openrc
2、要创建服务证书，完成这些步骤：
创建 nova 用户：
openstack user create --domain default \
--password-prompt nova
给 nova 用户添加 admin 角色：
openstack role add --project service --user nova admin
创建 nova 服务实体：
openstack service create --name nova \
--description "OpenStack Compute" compute
创建 Compute 服务 API 端点 ：
# openstack endpoint create --region RegionOne \
> compute public http://172.25.33.10:8774/v2.1/%\(tenant_id\)s
# openstack endpoint create --region RegionOne compute internal http://172.25.33.10:8774/v2.1/%\(tenant_id\)s

在 [DEFAULT] 部分，使能 Networking 服务：
[DEFAULT]
use_neutron = True
firewall_driver = nova.virt.firewall.NoopFirewallDriver
默认情况下，计算服务使用内置的防火墙服务。由于网络服务包含了防火墙服务，你必须使用``nova.virt.firewall.NoopFirewallDriver``防火墙服务来禁用掉计算服务内置的防火墙服务
在``[vnc]``部分，配置VNC代理使用控制节点的管理接口IP地址
[vnc]
vncserver_listen = $my_ip
vncserver_proxyclient_address = $my_ip
在 [glance] 区域，配置镜像服务 API 的位置：
[glance]
api_servers = http://controller:9292
在 [oslo_concurrency] 部分，配置锁路径：
[oslo_concurrency]
lock_path = /var/lib/nova/tmp
同步Compute 数据库：
# su -s /bin/sh -c "nova-manage api_db sync" nova
# su -s /bin/sh -c "nova-manage db sync" nova
# systemctl enable openstack-nova-api.service \
openstack-nova-consoleauth.service openstack-nova-scheduler.service \

rabbit_host = 172.25.33.10
rabbit_userid = openstack
rabbit_password = rabbit
vncserver_listen = $my_ip
vncserver_proxyclient_address = $my_ip
安装和配置计算节点：
minion2：172.25.33.11
安装软件包：
# yum install openstack-nova-compute
编辑``/etc/nova/nova.conf``文件并完成下面的操作
在``[DEFAULT]`` 和 [oslo_messaging_rabbit]部分，配置``RabbitMQ``消息队列的连接：
[DEFAULT]
rpc_backend = rabbit
[oslo_messaging_rabbit]
rabbit_host =172.25.33.10
rabbit_userid = openstack
rabbit_password =rabbit
在 “[DEFAULT]” 和 “[keystone_authtoken]” 部分，配置认证服务访问
[DEFAULT]
auth_strategy = keystone
[keystone_authtoken]
auth_uri = http://172.25.33.10:5000
auth_url = http://172.25.33.10:35357
memcached_servers = 172.25.33.10:11211
auth_type = password
project_domain_name = default
user_domain_name = default
project_name = service
username = nova
password = nova
在 [DEFAULT] 部分，配置 my_ip 选项
[DEFAULT]
my_ip = MANAGEMENT_INTERFACE_IP_ADDRESS
将其中的 MANAGEMENT_INTERFACE_IP_ADDRESS 替换为计算节点上的管理网络接口的IP 地址
my_ip =172.25.33.11
在 [DEFAULT] 部分，使能 Networking 服务：
[DEFAULT]
use_neutron = True
firewall_driver = nova.virt.firewall.NoopFirewallDriver
缺省情况下，Compute 使用内置的防火墙服务。由于 Networking 包含了防火墙服务，所以你必须通过使用 nova.virt.firewall.NoopFirewallDriver 来去除 Compute 内置的防火墙服务
在``[vnc]``部分，启用并配置远程控制台访问：
[vnc]
enabled = True
vncserver_listen = 0.0.0.0
vncserver_proxyclient_address = $my_ip
novncproxy_base_url = http://172.25.33.10:6080/vnc_auto.html
在 [glance] 区域，配置镜像服务 API 的位置：
[glance]
api_servers = http://172.25.33.10:9292
在 [oslo_concurrency] 部分，配置锁路径：
[oslo_concurrency]
lock_path = /var/lib/nova/tmp
官方文档漏掉的配置：回报错误：oslo_service.service [-] Error starting thread.
或PlacementNotConfigured: This compute is not configured to talk to the placement service
[placement]
auth_uri = http://172.25.33.10:5000
auth_url = http://172.25.33.10:35357
memcached_servers = 172.25.33.10:11211
auth_type = password
project_domain_name = default
user_domain_name = default
project_name = service
username = nova
password = nova
os_region_name = RegionOne
完成安装
1、确定您的计算节点是否支持虚拟机的硬件加速。
#egrep -c '(vmx|svm)' /proc/cpuinfo
如果这个命令返回了 one or greater 的值，那么你的计算节点支持硬件加速且不需要额外的配置。
如果这个命令返回了 zero 值，那么你的计算节点不支持硬件加速。你必须配置 libvirt 来使用 QEMU 去代替 KVM
# egrep -c '(vmx|svm)' /proc/cpuinfo
0
在 /etc/nova/nova.conf 文件的 [libvirt] 区域做出如下的编辑
[libvirt]
virt_type = qemu
2、启动计算服务及其依赖，并将其配置为随系统自动启动：
# systemctl enable libvirtd.service openstack-nova-compute.service
# systemctl start libvirtd.service openstack-nova-compute.service
验证操作：在控制节点172.25.33.10上进行
获得 admin 凭证来获取只有管理员能执行的命令的访问权限：
#. admin-openrc
列出服务组件，以验证是否成功启动并注册了每个进程：
# openstack compute service list

网络服务：
控制节点：
OpenStack网络（neutron）管理OpenStack环境中所有虚拟网络基础设施（VNI），物理网络基础设施（PNI）的接入层。OpenStack网络允许租户创建包括像 firewall， :term:`load balancer`和 :term:`virtual private network (×××)`等这样的高级虚拟网络拓扑。
配置：
1、获得 admin 凭证来获取只有管理员能执行的命令的访问权限：
. admin-openrc
2、要创建服务证书，完成这些步骤：
创建``neutron``用户：
openstack user create --domain default --password-prompt neutron
添加``admin`` 角色到``neutron`` 用户：
openstack role add --project service --user neutron admin
创建``neutron``服务实体：
# openstack service create --name neutron \
> --description "OpenStack Networking" network
创建网络服务API端点
# openstack endpoint create --region RegionOne \
> network public http://172.25.33.10:9696

至此，基础服务已经完成，可以创建实例：
----------
创建虚拟网络
---------
公共网络：
创建公共网络：
1、在控制节点上，加载 admin 凭证来获取管理员能执行的命令访问权限：
source admin-openrc
2、创建网络：
# neutron net-create --shared --provider:physical_network provider \
> --provider:network_type flat public

3、在网络上创建一个子网：
# neutron subnet-create --name provider --allocation-pool start=172.25.33.100,end=172.25.33.200 --dns-nameserver 114.114.114.114 --gateway 172.25.33.250 public 172.25.33.0/24

使用提供者物理网络的子网CIDR标记替换``PROVIDER_NETWORK_CIDR``。即上文列出的子网
将 DNS_RESOLVER 替换为DNS解析服务的IP地址。在大多数情况下，你可以从主机``/etc/resolv.conf`` 文件选择一个使用。
将``PUBLIC_NETWORK_GATEWAY`` 替换为公共网络的网关，一般的网关IP地址以 ”.1” 结尾。 也可以使用宿主机的IP。
创建m1.nano规格的主机
默认的最小规格的主机需要512 MB内存。对于环境中计算节点内存不足4 GB的，我们推荐创建只需要64 MB的``m1.nano``规格的主机。若单纯为了测试的目的，请使用``m1.nano``规格的主机来加载CirrOS镜像
# openstack flavor create --id 0 --vcpus 1 --ram 64 --disk 1 m1.nano
+----------------------------+---------+
| Field | Value |
+----------------------------+---------+
| OS-FLV-DISABLED:disabled | False |

| disk | 1 |
| id | 0 |
| name | m1.nano |
| os-flavor-access:is_public | True |
| properties | |
| ram | 64 |
| rxtx_factor | 1.0 |
| swap | |
| vcpus | 1 |
+----------------------------+---------+
生成一个键值对
大部分云镜像支持公共密钥认证而不是传统的密码认证。在启动实例前，你必须添加一个公共密钥到计算服务。
导入租户``demo``的凭证
$ . demo-openrc
生成和添加秘钥对：
$ ssh-keygen -q -N ""
$ openstack keypair create --public-key ~/.ssh/id_rsa.pub mykey
+-------------+-------------------------------------------------+
| Field | Value |
+-------------+-------------------------------------------------+
| fingerprint | 7f:a9:fd:62:e4:2b:87:84:27:f1:ce:d4:c1:89:f3:b8 |
| name | mykey |
| user_id | 251ad20a4d754dc4a104a3f5b8159142 |
+-------------+-------------------------------------------------+
验证公钥的添加：
# openstack keypair list
+-------+-------------------------------------------------+
| Name | Fingerprint |
+-------+-------------------------------------------------+
| mykey | 7f:a9:fd:62:e4:2b:87:84:27:f1:ce:d4:c1:89:f3:b8 |
+-------+-------------------------------------------------+
增加安全组规则
默认情况下， ``default``安全组适用于所有实例并且包括拒绝远程访问实例的防火墙规则。对诸如CirrOS这样的Linux镜像，我们推荐至少允许ICMP (ping) 和安全shell(SSH)规则。
添加规则到 default 安全组。
允许 ICMP (ping)：
# openstack security group rule create --proto icmp default
