控制節點安裝與設定

  1. 安裝控制節點 openstack-nova-* 套件。 
    [root@ip112 ~]# yum install openstack-nova-api openstack-nova-conductor \
openstack-nova-console openstack-nova-novncproxy \
openstack-nova-scheduler openstack-nova-placement-api
  2. 編輯 /etc/nova/nova.conf，設定如下章節： 
    [root@ip112 ~]# vim /etc/nova/nova.conf 
[root@ip112 ~]# egrep '^(\[DEF|\[api_d|\[data|\[api|\[keyst|\[vnc|\
\[glance|\[oslo_c|\[place|[a-z])' /etc/nova/nova.conf 
[DEFAULT]
enabled_apis = osapi_compute,metadata
transport_url = rabbit://openstack:123qwe@controller
my_ip = 163.17.10.112
use_neutron = True
firewall_driver = nova.virt.firewall.NoopFirewallDriver
[api]
auth_strategy = keystone
[api_database]
connection = mysql+pymysql://nova:123qwe@controller/nova_api
[database]
connection = mysql+pymysql://nova:123qwe@controller/nova
[glance]
api_servers = http://controller:9292
[keystone]
[keystone_authtoken]
auth_url = http://controller:5000/v3
memcached_servers = controller:11211
auth_type = password
project_domain_name = default
user_domain_name = default
project_name = service
username = nova
password = 123qwe
[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:5000/v3
username = placement
password = 123qwe
[vnc]
enabled = true
server_listen = $my_ip
server_proxyclient_address = $my_ip
  3. 編輯 /etc/httpd/conf.d/00-nova-placement-api.conf，開放所有 IP 可以存取 /usr/bin 目錄。 
    [root@ip112 ~]# vim /etc/httpd/conf.d/00-nova-placement-api.conf 
[root@ip112 ~]# cat /etc/httpd/conf.d/00-nova-placement-api.conf
Listen 8778

<VirtualHost *:8778>
  WSGIProcessGroup nova-placement-api
  WSGIApplicationGroup %{GLOBAL}
  WSGIPassAuthorization On
  WSGIDaemonProcess nova-placement-api processes=3 threads=1 user=nova group=nova
  WSGIScriptAlias / /usr/bin/nova-placement-api
  <IfVersion >= 2.4>
    ErrorLogFormat "%M"
  </IfVersion>
  ErrorLog /var/log/nova/nova-placement-api.log

</VirtualHost>

Alias /nova-placement-api /usr/bin/nova-placement-api
<Location /nova-placement-api>
  SetHandler wsgi-script
  Options +ExecCGI
  WSGIProcessGroup nova-placement-api
  WSGIApplicationGroup %{GLOBAL}
  WSGIPassAuthorization On

      Require all granted
   </IfVersion>
   <IfVersion < 2.4>
      Order allow,deny
      Allow from all
   </IfVersion>
</Directory>
  4. 重新啟動 httpd 服務。 
    [root@ip112 ~]# systemctl restart httpd
  5. 以用戶 nova 執行 nova-manage 進行 nova-api 資料庫同步，此步驟輸出的錯誤訊息皆可忽略。 
    [root@ip112 ~]# su -s /bin/sh -c "nova-manage api_db sync" nova
/usr/lib/python2.7/site-packages/oslo_db/sqlalchemy/enginefacade.py:332: 
NotSupportedWarning: Configuration option(s) ['use_tpool'] not supported
exception.NotSupportedWarning
  6. 以用戶 nova 執行 nova-manage 產生 cell0 資料庫，此步驟輸出的錯誤訊息皆可忽略。 
    [root@ip112 ~]# su -s /bin/sh -c "nova-manage cell_v2 map_cell0" nova
/usr/lib/python2.7/site-packages/oslo_db/sqlalchemy/enginefacade.py:332: 
NotSupportedWarning: Configuration option(s) ['use_tpool'] not supported
  exception.NotSupportedWarning
  7. 以用戶 nova 執行 nova-manage 產生 cell1 資料庫，此步驟輸出的錯誤訊息皆可忽略。 
    [root@ip112 ~]# su -s /bin/sh -c "nova-manage cell_v2 create_cell --name=cell1 --verbose" nova
/usr/lib/python2.7/site-packages/oslo_db/sqlalchemy/enginefacade.py:332: 
NotSupportedWarning: Configuration option(s) ['use_tpool'] not supported
  exception.NotSupportedWarning
4b4e2923-ee89-4057-b7d1-473951f313c2
  8. 以用戶 nova 執行 nova-manage 進行 nova 資料庫同步，此步驟輸出的錯誤訊息皆可忽略。 
    [root@ip112 ~]# su -s /bin/sh -c "nova-manage db sync" nova
/usr/lib/python2.7/site-packages/oslo_db/sqlalchemy/enginefacade.py:332: 
NotSupportedWarning: Configuration option(s) ['use_tpool'] not supported
  exception.NotSupportedWarning
/usr/lib/python2.7/site-packages/pymysql/cursors.py:166: Warning: (1831, 
u'Duplicate index `block_device_mapping_instance_uuid_virtual_name_device_name_idx`.

  result = self._query(query)
/usr/lib/python2.7/site-packages/pymysql/cursors.py:166: Warning: (1831, u'Duplicate 
index `uniq_instances0uuid`. This is deprecated and will be disallowed in a future release.')
  result = self._query(query)
  9. 確認 nova cell0 cell1 註冊正確，此步驟輸出的錯誤訊息皆可忽略。 
    [root@ip112 ~]# nova-manage cell_v2 list_cells
/usr/lib/python2.7/site-packages/oslo_db/sqlalchemy/enginefacade.py:332: 
NotSupportedWarning: Configuration option(s) ['use_tpool'] not supported

  10. 啟動 openstack-nova 控制節點相關的服務，並設定開機啟動。 
    [root@ip112 ~]# systemctl enable openstack-nova-api.service \
openstack-nova-consoleauth.service openstack-nova-scheduler.service \
openstack-nova-conductor.service openstack-nova-novncproxy.service
[root@ip112 ~]# systemctl start openstack-nova-api.service \
openstack-nova-consoleauth.service openstack-nova-scheduler.service \
openstack-nova-conductor.service openstack-nova-novncproxy.service
