openstack学习之九——计算节点安装nova

安装

安装nova-compute组件

yum install openstack-nova-compute

配置nova组件

修改配置文件，/etc/nova/nova.conf，修改内容如下

[DEFAULT]
enabled_apis = osapi_compute,metadata
transport_url = rabbit://openstack:123456@controller
my_ip = 10.0.0.31
use_neutron = true
firewall_driver = nova.virt.firewall.NoopFirewallDriver

[api]
auth_strategy = keystone

[keystone_authtoken]
www_authenticate_uri = http://controller:5000/
auth_url = http://controller:5000/
memcached_servers = controller:11211
auth_type = password
project_domain_name = Default
user_domain_name = Default
project_name = service
username = nova
password = 123456

[vnc]
enabled = true
server_listen = 0.0.0.0
server_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

[placement]
region_name = RegionOne
project_domain_name = Default
project_name = service
auth_type = password
user_domain_name = Default
auth_url = http://controller:5000/v3
username = placement
password = 123456

[libvirt]
virt_type = qemu

启动nova服务及其依赖项

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

在控制节点进行一下操作

获取操作权限

. admin-openrc

查看结算节点是否正常

openstack compute service list --service nova-compute

出现下图即为正常

发现并注册计算节点

 su -s /bin/sh -c "nova-manage cell_v2 discover_hosts --verbose" nova

设置适当间隔，编辑/etc/nova/nova.conf

[scheduler]
discover_hosts_in_cells_interval = 300
