#                                    计算节点 nova组件部署安装                                                #

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
