Re-enter new password:
Password updated successfully!
Remove anonymous users? [Y/n] y
Disallow root login remotely? [Y/n] y
Remove test database and access to it? [Y/n] y
Reload privilege tables now? [Y/n] y
b、安装rabbitmq
yum install rabbitmq-server -y
systemctl enable rabbitmq-server.service
systemctl start rabbitmq-server.service
# 添加用户和密码‘RABBIT_PASS’并授权
rabbitmqctl add_user openstack RABBIT_PASS
rabbitmqctl set_permissions openstack ".*" ".*" ".*"
# 启用rabbit dashboard
rabbitmq-plugins enable rabbitmq_management
c、安装memcache
认证服务认证缓存使用Memcached缓存令牌。缓存服务memecached运行在控制节点。在生产部署中，我们推荐联合启用防火墙、认证和加密保证它的安全。
yum install memcached python-memcached -y
vi /etc/sysconfig/memcached
OPTIONS="controller,10.0.0.11"
systemctl enable memcached.service
systemctl start memcached.service
2.安装认证服务

mysql keystone -e 'show tables;' -uroot -p
2.4 初始化fernet
keystone-manage fernet_setup --keystone-user keystone --keystone-group keystone
# 会在/etc/keystone/下生成 fernet-keys目录，里面存放了fernet 的token;如果身份认证服务在注册的时候出错可以重新初始化新的fernet token,把原来的删除。

4.nova服务
控制节点安装
nova-api 服务
接收和响应来自最终用户的计算API请求。此服务支持OpenStack计算服务API，Amazon EC2 API，以及特殊的管理API用于赋予用户做一些管理的操作。它会强制实施一些规则，发起多数的编排活动，例如运行一个实例。
nova-api-metadata 服务
接受来自虚拟机发送的元数据请求。服务一般在安装nova-network服务的多主机模式下使用。
一个持续工作的守护进程，通过Hypervior的API来创建和销毁虚拟机实例。例如：
- XenServer/XCP 的 XenAPI
- KVM 或 QEMU 的 libvirt
- VMware 的 VMwareAPI
过程是蛮复杂的。最为基本的，守护进程同意了来自队列的动作请求，转换为一系列的系统命令如启动一个KVM实例，然后，到数据库中更新它的状态。
nova-scheduler 服务拿到一个来自队列请求虚拟机实例，然后决定那台计算服务器主机来运行它。
nova-conductor模块
媒介作用于nova-compute服务与数据库之间。它排除了由nova-compute服务对云数据库的直接访问。nova-conductor模块可以水平扩展。但是，不要将它部署在运行nova-compute服务的主机节点上。
nova-cert模块
服务器守护进程向Nova Cert服务提供X509证书。用来为euca-bundle-image生成证书。仅仅是在EC2 API的请求中使用
nova-network worker 守护进程
与nova-compute服务类似，从队列中接受网络任务，并且操作网络。执行任务例如创建桥接的接口或者改变IPtables的规则。
nova-consoleauth 守护进程
授权控制台代理所提供的用户令牌。详情可查看nova-novncproxy和 nova-xvpvncproxy。该服务必须为控制台代理运行才可奏效。在集群配置中你可以运行二者中任一代理服务而非仅运行一个nova-consoleauth服务。
nova-novncproxy 守护进程
提供一个代理，用于访问正在运行的实例，通过VNC协议，支持基于浏览器的novnc客户端。
nova-spicehtml5proxy 守护进程
提供一个代理，用于访问正在运行的实例，通过 SPICE 协议，支持基于浏览器的 HTML5 客户端。
nova-xvpvncproxy 守护进程
提供一个代理，用于访问正在运行的实例，通过VNC协议，支持OpenStack特定的Java客户端。
nova-cert 守护进程
X509 证书。
nova客户端
用于用户作为租户管理员或最终用户来提交命令。
队列
一个在守护进程间传递消息的中央集线器。常见实现有RabbitMQ Zero MQ__等AMQP消息队列。
SQL数据库
存储构建时和运行时的状态，为云基础设施，包括有：
- 可用实例类型
- 使用中的实例
- 可用网络
- 项目
理论上，OpenStack计算可以支持任何和SQL-Alchemy所支持的后端数据库，通常使用SQLite3来做测试可开发工作，MySQL和PostgreSQL 作生产环境。
4.1 创建数据库
mysql -u root -p
CREATE DATABASE nova_api;
CREATE DATABASE nova;

IDENTIFIED BY 'NOVA_DBPASS';
GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'localhost' \

这个配置主要是让Exsi创建的虚拟机的网卡可以进入混杂模式。
如果没有这个设置，那么就会导致Exsi创建的虚拟机网卡不能分发包到OpenStack创建到虚拟机。

7.2 创建实例模板
有默认的虚拟机模板
[root@controller ~]# openstack flavor list
+----+-----------+-------+------+-----------+-------+-----------+
| ID | Name | RAM | Disk | Ephemeral | VCPUs | Is Public |
+----+-----------+-------+------+-----------+-------+-----------+
| 1 | m1.tiny | 512 | 1 | 0 | 1 | True |
| 2 | m1.small | 2048 | 20 | 0 | 1 | True |
| 3 | m1.medium | 4096 | 40 | 0 | 2 | True |
| 4 | m1.large | 8192 | 80 | 0 | 4 | True |
| 5 | m1.xlarge | 16384 | 160 | 0 | 8 | True |
+----+-----------+-------+------+-----------+-------+-----------+
# 如果要创建
[root@controller ~]# openstack flavor create --id 0 --vcpus 1 --ram 128 --disk 5 my_create
+----------------------------+-----------+
| Field | Value |
+----------------------------+-----------+
| OS-FLV-DISABLED:disabled | False |
| OS-FLV-EXT-DATA:ephemeral | 0 |
| disk | 5 |
| id | 0 |
| name | my_create |
| os-flavor-access:is_public | True |
| ram | 128 |
| rxtx_factor | 1.0 |
| swap | |
| vcpus | 1 |
+----------------------------+-----------+
7.3 创建密钥对
密钥对可以无密码直接ssh连接虚拟机，如果创建了会在创建实例的时候注入。
ssh-keygen -q -N "" -f ~/.ssh/id_rsa
[root@controller ~]# openstack keypair create --public-key ~/.ssh/id_rsa.pub my_ssh_key
+-------------+-------------------------------------------------+
| Field | Value |
+-------------+-------------------------------------------------+
| fingerprint | 44:59:f7:cb:05:70:8b:4b:e1:50:e8:36:4f:bf:51:f4 |
| name | my_ssh_key |
| user_id | c4d4838b317840c1b54ba1549a1010be |
+-------------+-------------------------------------------------+
7.4 创建安全组规则
默认情况下应该是可以ping通的，如果不行考虑添加。
[root@controller ~]# openstack security group rule create --proto icmp default
+-----------------------+--------------------------------------+
| Field | Value |
+-----------------------+--------------------------------------+
| id | af241acf-296b-428d-b368-529ec09c9dfe |
| ip_protocol | icmp |
| ip_range | 0.0.0.0/0 |
| parent_group_id | 15b8498c-eb91-47a2-8f7e-004c93d4803b |
| port_range | |
| remote_security_group | |
+-----------------------+--------------------------------------+
[root@controller ~]# openstack security group rule create --proto tcp --dst-port 22 default
+-----------------------+--------------------------------------+
| Field | Value |
+-----------------------+--------------------------------------+
| id | 73ada95f-81ff-42b1-95c9-e732d2f6480b |
| ip_protocol | tcp |
| ip_range | 0.0.0.0/0 |
| parent_group_id | 15b8498c-eb91-47a2-8f7e-004c93d4803b |
| port_range | 22:22 |
| remote_security_group | |
+-----------------------+--------------------------------------+
7.5 启动实例
[root@controller ~]# openstack flavor list
+----+-----------+-------+------+-----------+-------+-----------+
| ID | Name | RAM | Disk | Ephemeral | VCPUs | Is Public |
+----+-----------+-------+------+-----------+-------+-----------+

| 4 | m1.large | 8192 | 80 | 0 | 4 | True |
| 5 | m1.xlarge | 16384 | 160 | 0 | 8 | True |
+----+-----------+-------+------+-----------+-------+-----------+

# 这里显示的controller 是控制节点的主机名，如果在windows中没有配置解析会访问不了。解决方法
方法一： 配置hosts解析
方法二：修改计算节点nova.conf配置文件
vi /etc/nova/nova.conf

vncserver_listen = 0.0.0.0
vncserver_proxyclient_address = $my_ip
novncproxy_base_url = http://10.0.0.11:6080/vnc_auto.html
systemctl restart openstack-nova-compute.service
