平台必须起来哦
安装服务
yum install -y openstack-nova-compute lvm2
修改配置文件（红色为添加）
vi /etc/nova/nova.conf
[DEFAULT]
enabled_apis = osapi_compute,metadata
transport_url = rabbit://openstack:[email protected]
my_ip = 10.32.24.244
use_neutron = True
// 修改标红的三个服务的配置文件 （nova 、 rabbit 、 keystone）
firewall_driver = nova.virt.firewall.NoopFirewallDriver
rpc_backeend = rabbit
auth_strategy = keystone
[oslo_messaging_rabbit]
rabbit_host = controller
rabbit_userid = openstack
rabbit_password = 000000
[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 = 000000
[vnc]
enabled = true
server_listen = $my_ip
server_proxyclient_address = $my_ip
novncproxy_base_url = http://10.32.24.244:6080/vnc_auto.html
#virt_type=kvm
virt_type=qemu
//重新启动 、 开机自启
[[email protected] ~]# source admin-openrc.sh / / 生效环境变量
/ / 重启nove服务 设置开机自启
[[email protected] ~]#systemctl start libvirtd.service openstack-nova-compute.service
[[email protected] ~]# 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.
[[email protected] ~]# openstack compute service list --service nova-compute / / 查看有两个
