编辑/etc/nova/nova.conf文件
#vi /etc/nova/nova.conf在[DEFAULT]下添加enabled_apis = osapi_compute,metadatarpc_backend = rabbitauth_strategy = keystonemy_ip = 192.168.100.10use_neutron = Truefirewall_driver = nova.virt.firewall.NoopFirewallDriver
在[api_database]下添加connection = mysql+pymysql://nova:000000@controller/nova_api
在[database]下添加connection = mysql+pymysql://nova:000000@controller/nova
在[oslo_messaging_rabbit]下添加，配置 “RabbitMQ” 消息队列访问rabbit_host = controllerrabbit_userid = openstackrabbit_password = 000000
在[keystone_authtoken]部分，配置认证服务访问：auth_uri = http://controller:5000auth_url = http://controller:35357memcached_servers = controller:11211auth_type = passwordproject_domain_name = defaultuser_domain_name = defaultproject_name = serviceusername = novapassword = 000000

<h2 id="8">8.Compute 节点安装计算服务并配置</h2>
1.安装 nova-compute 软件包
[root@compute ~]# yum -y install openstack-nova-compute
复制代码
2.编辑 /etc/nova/nova.conf 配置文件
#vi /etc/nova/nova.conf
在 [DEFAULT] 下添加rpc_backend = rabbitauth_strategy = keystonemy_ip = 192.168.100.20use_neutron = Truefirewall_driver = nova.virt.firewall.NoopFirewallDriver

<h2 id="9">9.查看计算节点是否支持虚拟硬件加速</h2>
#egrep -c '(vmx|svm)' /proc/cpuinfo#因为一开始创建的时候在CPU选项部分勾选了虚拟化服务，所以是这样
复制代码
①如果这个命令返回了 1或者大于1 的值，那么你的计算节点支持硬件加速且不需要额外的配置。
②如果这个命令返回了 0 值，那么你的计算节点不支持硬件加速。你必须配置 libvirt 来使用 QEMU 去代替 KVM
编辑/etc/nova/nova.conf 文件的 [libvirt] #vi /etc/nova/nova.conf在[libvirtd]下添加virt_type = qemu
复制代码
<h2 id="10">10.计算节点启动 nova 服务并设置开机启动</h2>
[root@compute ~]# systemctl start libvirtd.service openstack-nova-compute.service[root@compute ~]# systemctl enable libvirtd.service openstack-nova-compute.service
