1、主机名修改 host文件解析

[root@localhost ~] hostnamectl set-hostname computer001
[root@localhost ~] vim /etc/hosts
192.168.40.151 controller
192.168.40.151 computer001
2、yum源配置
3、时间服务安装
4、永久关闭防火墙（firewalld和selinux）
[root@localhost ~]# systemctl stop firewalld
[root@localhost ~]# systemctl disable firewalld          #永久性关闭防火墙
[root@localhost ~]# setenforce 0                          #临时关闭selinux
[root@localhost ~]# vim /etc/selinux/config              #永久性关闭selinux
SELINUX=disabled
5、重启
[root@localhost ~]# reboot
6、nova组件安装
[root@computer001 ~]# yum install openstack-nova-compute
[DEFAULT]
enabled_apis = osapi_compute,metadata
transport_url = rabbit://openstack:RABBIT_PASS@controller
my_ip = MANAGEMENT_INTERFACE_IP_ADDRESS
use_neutron = True
firewall_driver = nova.virt.firewall.NoopFirewallDriver

[api]
auth_strategy = keystone

[keystone_authtoken]
auth_uri = http://controller:5000
auth_url = http://controller:35357
memcached_servers = controller:11211
auth_type = password
project_domain_name = default
user_domain_name = default
project_name = service
username = nova
password = NOVA_PASS

[vnc]
enabled = True
vncserver_listen = 0.0.0.0
vncserver_proxyclient_address = $my_ip
novncproxy_base_url = http://controller:6080/vnc_auto.html

[glance]
api_servers = http://controller:9292

[oslo_concurrency]
lock_path = /var/lib/nova/tmp

[libvirt]
virt_type = qemu

[root@computer001 ~] systemctl enable libvirtd.service openstack-nova-compute.service
[root@computer001 ~] systemctl start libvirtd.service openstack-nova-compute.service

验证安装是否成功：
    在控制节点上执行
[root@controller ~]# source admin.sh
[root@controller ~]# openstack compute service list
