六：OPENSTACK Queens部署computer服务

Posted 2021-04-24 MisterChen

备注：在计算节点安装computer服务

• 部署计算节点computer，安装软件包

[root@computer ~]# yum install -y openstack-nova-compute

• 编辑配置文件nova.conf

vim /etc/nova/nova.conf

[DEFAULT]

enabled_apis = osapi_compute,metadata

transport_url = rabbit://openstack:123456@controller

my_ip = 192.168.1.111

use_neutron = True

firewall_driver = nova.virt.firewall.NoopFirewallDriver

[api]

auth_strategy = keystone

[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 = 123456

[vnc]

enabled = True

server_listen = 0.0.0.0

server_proxyclient_address = $my_ip

novncproxy_base_url = http://192.168.1.110:6080/vnc_auto.html

[glance]

api_servers = http://controller:9292

[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 = 123456

[libvirt]

virt_type = kvm

• 在controller节点查看

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

• 启动服务

[root@controller ~]# systemctl enable libvirtd.service openstack-nova-compute.service

[root@controller ~]# systemctl start libvirtd.service openstack-nova-compute.service

备注：当您添加新的计算节点时，您必须在控制器节点上运行nova管理cellv2发现主机来注册这些新的计算节点。或者，您可以在/etc/nov/nova.conf中设置适当的间隔

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

或者：

修改nova.conf修改时间间隔:

[scheduler]

discover_hosts_in_cells_interval = 300
