1.Controller node安装Compute service
1.1 安装前准备
1.1.1 数据库配置
1.创建 nova_api, nova, nova_cell0, placement数据库
mysql
CREATE DATABASE nova_api;
CREATE DATABASE nova;
CREATE DATABASE nova_cell0;
CREATE DATABASE placement;
2.为上述数据库创建用户及授权
GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'localhost' IDENTIFIED BY 'NOVA_DBPASS';
GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'%' IDENTIFIED BY 'NOVA_DBPASS';
GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'localhost' IDENTIFIED BY 'NOVA_DBPASS';
GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'%' IDENTIFIED BY 'NOVA_DBPASS';

user_domain_name = default
project_name = service
username = nova
password = NOVA_PASS
3.修改my_ip ，这个MANAGEMENT_INTERFACE_IP_ADDRESS要替换成这台compute节点在管理网络中的ip地址，本次搭建中使用的地址为10.0.0.31。
[DEFAULT]
# ...
my_ip = MANAGEMENT_INTERFACE_IP_ADDRESS
4.开启network service支持
[DEFAULT]
# ...
use_neutron = true

project_domain_name = Default
project_name = service
auth_type = password
user_domain_name = Default
auth_url = http://controller:5000/v3
username = placement
password = PLACEMENT_PASS
2.2 确认安装
1.在compute节点上使用如下命令
egrep -c '(vmx|svm)' /proc/cpuinfo
如果返回结果不是0那么说明你的计算节点cpu支持硬件加速，如果返回结果是0，如下，那么需要额外配置。
root@ubuntu-ComputeNode:/home/ubuntu# egrep -c '(vmx|svm)' /proc/cpuinfo
0
root@ubuntu-ComputeNode:/home/ubuntu#
修改/etc/nova/nova-compute.conf
[libvirt]
# ...
virt_type = qemu
2.重启服务
service nova-compute restart
3.将计算节点添加到cell数据库中
以下操作均在controller node上执行
1.导入环境变量,确认一下compute节点是否在数据库里
root@ubuntu-ControllerNode:/home/ubuntu# . admin.opensrc
root@ubuntu-ControllerNode:/home/ubuntu# openstack compute service list --service nova-compute
+----+--------------+--------------------+------+---------+-------+----------------------------+
| ID | Binary | Host | Zone | Status | State | Updated At |
+----+--------------+--------------------+------+---------+-------+----------------------------+
| 5 | nova-compute | ubuntu-ComputeNode | nova | enabled | up | 2019-01-10T03:40:20.000000 |
+----+--------------+--------------------+------+---------+-------+----------------------------+
2.发现计算节点
su -s /bin/sh -c "nova-manage cell_v2 discover_hosts --verbose" nova
注：这个操作需要在每次添加计算节点后都执行一次。如果觉得麻烦也可以在/etc/nova/nova.conf中添加自动扫描：
[scheduler]
discover_hosts_in_cells_interval = 300
