安装并配置计算节点
http://dl.fedoraproject.org/pub/epel/7/x86_64/Packages/e/epel-release-7-11.noarch.rpm
yum install openstack-nova-compute 安装包报错
(yum install rpm* rpm-build rpmdev*
rpmbuild --rebuild --clean qemu-kvm-rhev-2.9.0-16.el7_4.8.src.rpm （需要依赖安装）
cd /root/rpmbuild/RPMS/x86_64/ yum 直接使用编译生成的包 yum remove 卸载原来
)

启动服务
# systemctl enable libvirtd.service openstack-nova-compute.service
# systemctl start libvirtd.service openstack-nova-compute.service
systemctl status libvirtd.service openstack-nova-compute.service
（网络配置
systemctl stop firewalld.service systemctl disable firewalld.service关防火墙
systemctl stop iptables systemctl disable iptables.service
rabbit 的openstack 用户不见了 rabbitmqctl list_users）
将计算节点加到数据库
. admin-openrc
openstack compute service list --service nova-compute列表
su -s /bin/sh -c "nova-manage cell_v2 discover_hosts --verbose" nova 寻找计算机
/etc/nova/nova.conf
[scheduler]
discover_hosts_in_cells_interval = 300
验证安装
. admin-openrc 管理员环境变量
openstack compute service list openstack计算服务列表
openstack catalog list openstack服务列表
openstack image list openstack图像列表
（9292端口未启动 glance 未启动）
nova-status upgrade check 检查单元格和展示位置API是否成功运行
(vi /etc/httpd/conf.d/00-nova-placement-api.conf新增

<Directory /usr/bin/nova-placement-api>

There are no compute resource providers in the Placement
service but there are 1 compute nodes in the deployment.
This means no compute nodes are reporting into the
Placement service and need to be upgraded and/or fixed.
（计算节点PUT提交资源不成功，查看计算节点硬件是否符合要求，CPU、内存。。）
