openstack Queens版本在centos7.1，最小化安装(安装nova(计算节点))

yum installopenstack-nova-compute -y

 

修改配置文件

/etc/nova/nova.conf

[DEFAULT]

my_ip = 10.0.2.112

use_neutron = True

firewall_driver =nova.virt.firewall.NoopFirewallDriver

enabled_apis=osapi_compute,metadata

transport_url = rabbit://openstack:test.2018@controller

 

 

[api]

auth_strategy=keystone

 

[glance]

api_servers=http://controller:9292

 

[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 = test.2018

 

[oslo_concurrency]

lock_path=/var/lib/nova/tmp

 

[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 = test.2018

 

 

 

[vnc]

enabled = True

server_listen = 0.0.0.0

server_proxyclient_address =10.0.2.112

novncproxy_base_url = http://controller:6080/vnc_auto.html

 

 

若为0将需要将/etc/nova/nova.conf中的virt_type=kvm 修改为 virt_type=qemu

 

 

启动服务

# systemctl enable libvirtd.serviceopenstack-nova-compute.service
# systemctl startlibvirtd.service openstack-nova-compute.service

 

 

********************************************************************

在控制节点中查看

[root@con01 ~]# openstack computeservice list --service nova-compute

 

添加新主机

[root@con01 ~]#  su -s /bin/sh -c "nova-manage cell_v2discover_hosts --verbose" nova

 

若不想手动添加 可修改/etc/nova/nova.conf配置文件

[scheduler]
discover_hosts_in_cells_interval = 300
