前提:source admin-openstack

6.1.创建nova和nova_api数据库 

mysql> CREATE DATABASE nova_api
mysql> CREATE DATABASE nova;

6.2.数据库进行授权

mysql> GRANT ALL PRIVILEGES ON nova_api.* TO ‘nova‘@‘localhost‘ IDENTIFIED BY ‘nova‘;
mysql> GRANT ALL PRIVILEGES ON nova_api.* TO ‘nova‘@‘%‘ IDENTIFIED BY ‘nova‘;
mysql> GRANT ALL PRIVILEGES ON nova.* TO ‘nova‘@‘localhost‘ IDENTIFIED BY ‘nova‘;
mysql> GRANT ALL PRIVILEGES ON nova.* TO ‘nova‘@‘%‘   IDENTIFIED BY ‘nova‘;

6.3 创建nova用户 nova密码

 openstack user create --domain default   --password-prompt nova

User Password:
Repeat User Password:
+---------------------+----------------------------------+
| Field               | Value                            |
+---------------------+----------------------------------+

+---------------------+----------------------------------+

6.4 给nova添加admin的角色

openstack role add --project service --user nova admi

6.7 安装软件包nova  除了nova的计算节点

yum install openstack-nova-api openstack-nova-conductor   openstack-nova-console openstack-nova-novncproxy   openstack-nova-scheduler

6.8 修改nova的配置文件

[root@linux-node1 ~]# grep  ‘^[a-Z]‘  /etc/nova/nova.conf
auth_strategy=keystone  #使用kestone认证
use_neutron=True        #使用neutron的网络
enabled_apis=osapi_compute,metadata  #支持的API模型
firewall_driver = nova.virt.firewall.NoopFirewallDriver #防火墙驱动
connection=mysql+pymysql://nova:nova@192.168.56.11/nova_api  #keystone认证
connection=mysql+pymysql://nova:nova@192.168.56.11/nova
api_servers=http://192.168.56.11:9292
auth_uri = http://192.168.56.11:5000
auth_url = http://192.168.56.11:35357
memcached_servers = 192.168.56.11:11211
auth_type = password
project_domain_name = default
user_domain_name = default
project_name = service 
username = nova
password = nova
lock_path=/var/lib/nova/tmp  #锁文件
transport_url=rabbit://openstack:openstack@192.168.56.11 #消息队列
vncserver_listen=0.0.0.0 #vnc监听的IP
vncserver_proxyclient_address=192.168.56.11 #vncproxy  h5的界面化工具
[root@linux-node1 ~]#

6.9 同步书nova的数据库和nova-api的 数据库

# su -s /bin/sh -c "nova-manage api_db sync" nova
# su -s /bin/sh -c "nova-manage db sync" nova

6.10 启动计算节点

# 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   openstack-nova-consoleauth.service openstack-nova-scheduler.service   openstack-nova-conductor.service openstack-nova-novncproxy.servic

6.11 验证最后的成功

[root@linux-node1 nova]# openstack host list 
+-------------+-------------+----------+
| Host Name   | Service     | Zone     |
+-------------+-------------+----------+
| linux-node1 | consoleauth | internal |
| linux-node1 | conductor   | internal |
| linux-node1 | scheduler   | internal |
+-------------+-------------+----------+
[root@linux-node1 nova]#
