###openstack-ocata 單節點安裝 部署 目錄彙總

一 安裝nova服務

yum install openstack-nova-compute -y

--------------------------------------------------------------------------------

二 配置nova檔案
cp /etc/nova/nova.conf /etc/nova/nova.conf.bak
> /etc/nova/nova.conf

##注意修改my_ip

echo '
[DEFAULT]
# ...
enabled_apis = osapi_compute,metadata
transport_url = rabbit://openstack:

[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 = nova

[vnc]
# ...
enabled = True
vncserver_listen = 0.0.0.0
vncserver_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]
# ...
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

[libvirt]
# ...
virt_type = qemu

'>/etc/nova/nova.conf

--------------------------------------------------------------------------------

三 驗證計算節點是否支援虛擬化

egrep -c '(vmx|svm)' /proc/cpuinfo 
返回為0則不支援，返回>0則支援

--------------------------------------------------------------------------------
四 啟動nova服務

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

--------------------------------------------------------------------------------

五 控制節點執行驗證操作

. adminrc

openstack hypervisor list
+----+---------------------+-----------------+-----------+-------+
| ID | Hypervisor Hostname | Hypervisor Type | Host IP | State |
+----+---------------------+-----------------+-----------+-------+
| 1 | compute1 | QEMU | 10.0.0.31 | up |
+----+---------------------+-----------------+-----------+-------+
