Centos7安装部署openstack--nova计算服务（计算节点）

一、安装服务

yum install openstack-nova-compute -y
yum install openstack-utils.noarch -y

二、修改配置文件

 cp /etc/nova/nova.conf{,.bak}
 grep '^[a-z\[]' /etc/nova/nova.conf.bak >/etc/nova/nova.conf

 openstack-config --set /etc/nova/nova.conf DEFAULT enabled_apis  osapi_compute,metadata
 openstack-config --set /etc/nova/nova.conf DEFAULT rpc_backend rabbit
 openstack-config --set /etc/nova/nova.conf DEFAULT auth_strategy keystone
 openstack-config --set /etc/nova/nova.conf DEFAULT my_ip 10.0.0.31
 openstack-config --set /etc/nova/nova.conf DEFAULT use_neutron True
 openstack-config --set /etc/nova/nova.conf DEFAULT firewall_driver nova.virt.firewall.NoopFirewallDriver
 openstack-config --set /etc/nova/nova.conf glance api_servers http://controller:9292
 openstack-config --set /etc/nova/nova.conf keystone_authtoken auth_uri http://controller:5000
 openstack-config --set /etc/nova/nova.conf keystone_authtoken auth_url http://controller:35357
 openstack-config --set /etc/nova/nova.conf keystone_authtoken memcached_servers controller:11211
 openstack-config --set /etc/nova/nova.conf keystone_authtoken auth_type password
 openstack-config --set /etc/nova/nova.conf keystone_authtoken project_domain_name default
 openstack-config --set /etc/nova/nova.conf keystone_authtoken user_domain_name default
 openstack-config --set /etc/nova/nova.conf keystone_authtoken project_name service
 openstack-config --set /etc/nova/nova.conf keystone_authtoken username nova
 openstack-config --set /etc/nova/nova.conf keystone_authtoken password NOVA_PASS
 openstack-config --set /etc/nova/nova.conf oslo_concurrency lock_path /var/lib/nova/tmp
 openstack-config --set /etc/nova/nova.conf oslo_messaging_rabbit rabbit_host controller
 openstack-config --set /etc/nova/nova.conf oslo_messaging_rabbit rabbit_userid openstack
 openstack-config --set /etc/nova/nova.conf oslo_messaging_rabbit rabbit_password RABBIT_PASS
 openstack-config --set /etc/nova/nova.conf vnc enabled True
 openstack-config --set /etc/nova/nova.conf vnc vncserver_listen 0.0.0.0
 openstack-config --set /etc/nova/nova.conf vnc vncserver_proxyclient_address '$my_ip'
 openstack-config --set /etc/nova/nova.conf vnc novncproxy_base_url http://controller:6080/vnc_auto.html

　　记得添加placement的配置文件

[DEFAULT]
# ...
transport_url = rabbit://openstack:RABBIT_PASS@controller
[placement]
# ...
os_region_name = RegionOne
project_domain_name = Default
project_name = service
auth_type = password
user_domain_name = Default
auth_url = http://controller:35357/v3
username = placement
password = PLACEMENT_PASS

三、启动服务

systemctl enable libvirtd openstack-nova-compute.service
systemctl start libvirtd openstack-nova-compute.service

四、查看服务
