计算服务
[root@node1 ~]# cat /etc/hosts
192.168.200.101 openstack-vip.wyh.net
安装参考网站
https://docs.openstack.org/nova/stein/install/index.html
CentOS安装和配置计算节点
安装软件包：
[root@node1 ~]# yum install openstack-nova-compute -y
编辑/etc/nova/nova.conf文件并完成以下操作：
在此[DEFAULT]部分中，仅启用计算和元数据API：
在该[DEFAULT]部分中，配置RabbitMQ消息队列访问：
[root@node1 ~]# vim /etc/nova/nova.conf
[DEFAULT]
# ...
enabled_apis = osapi_compute,metadata
transport_url = rabbit://openstack:openstack123@openstack-vip.wyh.net
在[api]和[keystone_authtoken]部分中，配置身份服务访问
[api]
auth_strategy = keystone
[keystone_authtoken]
auth_url = http://openstack-vip.wyh.net:5000/v3
memcached_servers = openstack-vip.wyh.net:11211
auth_type = password
project_domain_name = Default
user_domain_name = Default
project_name = service
username = nova
password = nova
在该[DEFAULT]部分中，配置my_ip选项：
在本[DEFAULT]节中，启用对网络服务的支持：
use_neutron = true
firewall_driver = nova.virt.firewall.NoopFirewallDriver
在该[vnc]部分中，启用和配置远程控制台访问：
[vnc]
enabled = true
server_listen = 0.0.0.0
server_proxyclient_address = 192.168.200.103
这个ip地址为本机的ip地址
novncproxy_base_url = http://openstack-vip.wyh.net:6080/vnc_auto.html
在该[glance]部分中，配置图像服务API的位置：
[glance]
api_servers = http://openstack-vip.wyh.net:9292
在该[oslo_concurrency]部分中，配置锁定路径：
在该[placement]部分中，配置Placement API：
region_name = RegionOne
project_domain_name = Default
project_name = service
auth_type = password
user_domain_name = Default
auth_url = http://openstack-vip.wyh.net:5000/v3
username = placement
password = placement
由于[包装错误](https://bugzilla.redhat.com/show_bug.cgi?id=1430540)，您必须通过将以下配置添加到来启用对Placement API的访问 `/etc/httpd/conf.d/00-nova-placement-api.conf`：
[root@controller1 ~]# vim /etc/httpd/conf.d/00-placement-api.conf
添加到最后
<Directory /usr/bin>
<IfVersion >= 2.4>
Require all granted
</IfVersion>
<IfVersion < 2.4>
Order allow,deny
Allow from all
</IfVersion>
</Directory>
重新启动httpd服务：
确定您的计算节点是否支持虚拟机的硬件加速：
如果此命令返回值，则您的计算节点支持硬件加速，通常不需要其他配置。one or greater
如果此命令返回值zero，则您的计算节点不支持硬件加速，并且您必须配置libvirt为使用QEMU而不是KVM。
启动Compute服务及其相关性，并将其配置为在系统启动时自动启动：
[root@node1 ~]# systemctl enable libvirtd.service openstack-nova-compute.service
Created symlink from /etc/systemd/system/multi-user.target.wants/openstack-nova-compute.service to /usr/lib/systemd/system/openstack-nova-compute.service.
[root@node1 ~]# systemctl start libvirtd.service openstack-nova-compute.service
获取管理员凭据以启用仅管理员的CLI命令，然后确认数据库中有计算主机：
发现计算主机：
[root@controller1 ~]#su -s /bin/sh -c "nova-manage cell_v2 discover_hosts --verbose" nova
[root@controller1 ~]# openstack compute service list --service nova-compute
+----+--------------+------------------+------+---------+-------+----------------------------+
| ID | Binary | Host | Zone | Status | State | Updated At |
+----+--------------+------------------+------+---------+-------+----------------------------+
| 8 | nova-compute | node1.magedu.net | nova | enabled | up | 2019-12-18T10:28:30.000000 |
添加新的计算节点时，必须在控制器节点上运行以注册这些新的计算节点。另外，您可以在中设置适当的时间间隔 ：nova-manage cell_v2 discover_hosts/etc/nova/nova.conf
[root@node1 ~]# vim /etc/nova/nova.conf
9506 discover_hosts_in_cells_interval=60
每隔60秒扫描一次计算节点
[root@node1 ~]# systemctl restart libvirtd.service openstack-nova-compute.service
验证操作
[root@controller1 ~]# nova service-list
