一、一般情况下，OpenStack至少需要两个物理机器，或者称之为两个节点，也就是前面提到的控制节点和计算节点。一般情况下，控制节点不需要过高的硬件资源，计算节点需要比较高的硬件资源，但是经常用户的两个节点的硬件信息都是一样的，所以我们也会在控制节点上安装Nova，来使用控制节点的硬件资源信息。
二、在控制节点上安装计算服务
1. 约定: nova使用MySQL数据库存储相关数据，相关参数如下:
库名: nova
账户: novadbadmin
密码: nova4smtest
2. 安装计算服务
sudo apt-get install nova-api nova-cert nova-conductor nova-consoleauth nova-novncproxy nova-scheduler python-novaclient
3. 编辑/etc/nova/nova.conf文件，设置数据库、消息服务及IP相关参数，
[ sudo vi /etc/nova/nova.conf ]
更新设置如下：
#-----------nova config1---------------------------------------
[database]
connection = mysql://novadbadmin:nova4smtest@192.168.3.180/nova
[DEFAULT]
rpc_backend = rabbit
rabbit_host = 192.168.3.180
rabbit_userid = guest
rabbit_password = mq4smtest
rabbit_port = 5672
#控制节点的IP
my_ip = 192.168.3.180
vncserver_listen = 192.168.3.180
vncserver_proxyclient_address = 192.168.3.180
4. 删除SQLite数据库
sudo rm /var/lib/nova/nova.sqlite
5. 创建数据库、账户并配置权限
6. 创建Compute Service表
sudo nova-manage db sync
7. 创建Compute Service 账户并设置角色
keystone user-create --name=nova --pass=nova4smtest --email=sm@163.com
keystone user-role-add --user=nova --tenant=service --role=admin
8. 编辑/etc/nova/nova.conf文件，设置相关参数，
[ sudo vi /etc/nova/nova.conf ]
更新设置如下：
[DEFAULT]
auth_strategy = keystone
[keystone_authtoken]
auth_uri = http://192.168.3.180:5000
auth_host = 192.168.3.180
auth_port = 35357
auth_protocol = http
admin_tenant_name = service
admin_user = nova
admin_password = nova4smtest
检查一下nova.conf的相关信息
9. 创建服务
keystone service-create --name=nova --type=compute --description="OpenStack Compute Service"
10. 创建接入端点
keystone endpoint-create --service-id=$(keystone service-list | awk '/ compute / {print $2}') --publicurl=http://192.168.3.180:8774/v2/%\(tenant_id\)s --internalurl=http://192.168.3.180:8774/v2/%\(tenant_id\)s --adminurl=http://192.168.3.180:8774/v2/%\(tenant_id\)s
11. 重启服务
sudo service nova-api restart
sudo service nova-cert restart
sudo service nova-consoleauth restart
sudo service nova-scheduler restart
sudo service nova-conductor restart
sudo service nova-novncproxy restart
12. 测试查看计算服务状态
1) sudo nova-manage service list
所有组件都是微笑，说明nova已经正确安装完毕。
2) nova image-list
13. 日志文件
存储位置为: /var/log/nova/
存储文件为：
/var/log/nova/nova-api.log
/var/log/nova/nova-cert.log
/var/log/nova/nova-conductor.log
/var/log/nova/nova-consoleauth.log
/var/log/nova/nova-manage.log
/var/log/nova/nova-scheduler.log
注意：如果需要控制节点也充当计算功能，需要参考部署5、部署8和部署9的第一部分的操作，在控制节点重复操作一遍即可。

vncserver_listen = 192.168.3.180
vncserver_proxyclient_address = 192.168.3.180
4. 删除SQLite数据库
sudo rm /var/lib/nova/nova.sqlite
5. 创建数据库、账户并配置权限
sudo mysql -uroot -p#db4smtest# -e 'CREATE DATABASE nova;'
sudo mysql -uroot -p#db4smtest# -e 'CREATE USER novadbadmin;'
sudo mysql -uroot -p#db4smtest# -e "GRANT ALL PRIVILEGES ON nova.* TO 'novadbadmin'@'localhost' IDENTIFIED BY 'nova4smtest';"
sudo mysql -uroot -p#db4smtest# -e "GRANT ALL PRIVILEGES ON nova.* TO 'novadbadmin'@'%' IDENTIFIED BY 'nova4smtest';"
sudo mysql -uroot -p#db4smtest# -e "SET PASSWORD FOR 'novadbadmin'@'%' = PASSWORD('nova4smtest');"6. 创建Compute Service表

所有组件都是微笑，说明nova已经正确安装完毕。
2) nova image-list
sm@controller:~$ nova image-list +--------------------------------------+---------------------+--------+--------+ | ID | Name | Status | Server | +--------------------------------------+---------------------+--------+--------+ | 6dbf0884-e9bb-406e-9f77-32aef79dd976 | cirros-0.3.2-x86_64 | ACTIVE | | +--------------------------------------+---------------------+--------+--------+<span style="font-family: 'Microsoft YaHei'; background-color: rgb(255, 255, 255);"> </span>有可用的镜像，可提供正常提高服务了。
13. 日志文件
存储位置为: /var/log/nova/
存储文件为：
/var/log/nova/nova-api.log
/var/log/nova/nova-cert.log
/var/log/nova/nova-conductor.log
/var/log/nova/nova-consoleauth.log
/var/log/nova/nova-manage.log
/var/log/nova/nova-scheduler.log
注意：如果需要控制节点也充当计算功能，需要参考部署5、部署8和部署9的第一部分的操作，在控制节点重复操作一遍即可。
