OpenStack 介紹

openstack目前已經更新到P版，與以往不同的是之前每6個月發布一個新的版本，從P版本開始，每年會發布一個新的版本。

官方安裝文檔：https://docs.openstack.org/install-guide/

測試環境說明

控制節點（Controller）： openstack-node1 <192.168.10.11>
計算節點（Computer）: openstack-node2 <192.168.10.12> ， openstack-node3 <192.168.10.13>
網絡環境： 單一網絡，橋接模式
存儲模式： 本地存儲

環境初始化準備

1、 安裝ntp服務，同步時間。

2、安裝openstack 包

# yum install -y centos-release-openstack-pike

3、在node1安裝數據庫（https://docs.openstack.org/install-guide/environment-sql-database-rdo.html）

# yum install mariadb mariadb-server python2-PyMySQL -y

4、配置數據庫并啟動

vim /etc/my.cnf.d/openstack.cnf[mysqld] bind-address = 192.168.10.11 default-storage-engine = innodb innodb_file_per_table = on max_connections = 4096 collation-server = utf8_general_ci character-set-server = utf8

啟動數據庫并初始化：

# systemctl enable mariadb.service # systemctl start mariadb.service # mysql_secure_installation

5、創建數據庫

MariaDB [(none)]> create database keystone; Query OK, 1 row affected (0.00 sec)MariaDB [(none)]> create database nova; Query OK, 1 row affected (0.00 sec)MariaDB [(none)]> create database nova_api; Query OK, 1 row affected (0.00 sec)MariaDB [(none)]> create database glance; Query OK, 1 row affected (0.00 sec)MariaDB [(none)]> create database neutron; Query OK, 1 row affected (0.00 sec)MariaDB [(none)]> create database cinder; Query OK, 1 row affected (0.00 sec)MariaDB [(none)]> CREATE DATABASE nova_cell0; Query OK, 1 row affected (0.00 sec)MariaDB [(none)]> show databases; +--------------------+ | Database | +--------------------+ | cinder | | glance | | information_schema | | keystone | | mysql | | neutron | | nova | | nova_api | | nova_cell0 | | performance_schema | +--------------------+ 9 rows in set (0.00 sec)

授權：

MariaDB [(none)]> grant all on keystone.* to 'keystone'@'localhost' identified by 'keystone'; Query OK, 0 rows affected (0.00 sec)MariaDB [(none)]> grant all on keystone.* to 'keystone'@'%' identified by 'keystone'; Query OK, 0 rows affected (0.00 sec)MariaDB [(none)]> grant all on nova.* to 'nova'@'localhost' identified by 'nova'; Query OK, 0 rows affected (0.00 sec)MariaDB [(none)]> grant all on nova.* to 'nova'@'%' identified by 'nova'; Query OK, 0 rows affected (0.00 sec)MariaDB [(none)]> grant all on nova_api.* to 'nova'@'localhost' identified by 'nova'; Query OK, 0 rows affected (0.00 sec)MariaDB [(none)]> grant all on nova_api.* to 'nova'@'%' identified by 'nova'; Query OK, 0 rows affected (0.00 sec)MariaDB [(none)]> grant all on glance.* to 'glance'@'localhost' identified by 'glance'; Query OK, 0 rows affected (0.00 sec)MariaDB [(none)]> grant all on glance.* to 'glance'@'%' identified by 'glance'; Query OK, 0 rows affected (0.00 sec)MariaDB [(none)]> grant all on neutron.* to 'neutron'@'localhost' identified by 'neutron'; Query OK, 0 rows affected (0.00 sec)MariaDB [(none)]> grant all on neutron.* to 'neutron'@'%' identified by 'neutron'; Query OK, 0 rows affected (0.00 sec)MariaDB [(none)]> grant all on cinder.* to 'cinder'@'localhost' identified by 'cinder'; Query OK, 0 rows affected (0.00 sec)MariaDB [(none)]> grant all on cinder.* to 'cinder'@'%' identified by 'cinder'; Query OK, 0 rows affected (0.00 sec)MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova_cell0.* TO 'nova'@'localhost' IDENTIFIED BY 'nova'; Query OK, 0 rows affected (0.00 sec)MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova_cell0.* TO 'nova'@'%' IDENTIFIED BY 'nova'; Query OK, 0 rows affected (0.00 sec)

測試用戶和授權：

[root@node1 ~]# mysql -ukeystone -pkeystone; MariaDB [(none)]> show databases; +--------------------+ | Database | +--------------------+ | information_schema | | keystone | +--------------------+ 2 rows in set (0.00 sec)[root@node1 ~]# mysql -unova -pnova; MariaDB [(none)]> show databases; +--------------------+ | Database | +--------------------+ | information_schema | | nova | | nova_api | +--------------------+ 3 rows in set (0.00 sec)[root@node1 ~]# mysql -uglance -pglance; MariaDB [(none)]> show databases; +--------------------+ | Database | +--------------------+ | glance | | information_schema | +--------------------+ 2 rows in set (0.01 sec)[root@node1 ~]# mysql -uneutron -pneutron; MariaDB [(none)]> show databases; +--------------------+ | Database | +--------------------+ | information_schema | | neutron | +--------------------+ 2 rows in set (0.00 sec)[root@node1 ~]# mysql -ucinder -pcinder; MariaDB [(none)]> show databases; +--------------------+ | Database | +--------------------+ | cinder | | information_schema | +--------------------+ 2 rows in set (0.00 sec)

6、安裝配置rabbitMQ

[root@node1 ~]# yum install rabbitmq-server -y [root@node1 ~]# systemctl enable rabbitmq-server.service [root@node1 ~]# systemctl start rabbitmq-server.service [root@node1 ~]# rabbitmqctl add_user openstack openstack [root@node1 ~]# rabbitmqctl set_permissions openstack ".*" ".*" ".*"

檢查：
（1）. 如果要通過web界面登錄，查看rabbitMQ的狀態，需要開啟web登錄的插件：

rabbitmq-plugins enable rabbitmq_management

開啟后會rabbitMQ會開啟一個監聽15672的端口，使用此端口登錄web界面，使用賬號guest/guest可查看當前狀態。
（2）. rabbitMQ會監聽25672和2572端口。

7、安裝配置memecache:

[root@node1 ~]# yum install memcached python-memcached -y

修改配置文件,修改為本地IP地址和添加contoller節點的IP標識：

vim /etc/sysconfig/memcachedOPTIONS="-l 192.168.10.11,::1"

啟動服務：

# systemctl enable memcached.service # systemctl start memcached.service

8、控制節點安裝如下軟件包：
安裝keystone

# yum install -y openstack-keystone httpd mod_wsgi

安裝Glance

# yum install -y openstack-glance

安裝nova

# yum install -y openstack-nova-api openstack-nova-placement-api \openstack-nova-conductor openstack-nova-console \openstack-nova-novncproxy openstack-nova-scheduler

安裝neutron

# yum install -y openstack-neutron openstack-neutron-ml2 \ openstack-neutron-linuxbridge ebtables

安裝OpenStack命令

yum install -y python-openstackclient openstack-selinux

9、計算節點安裝 nova-computer 和neutron的相關組件：

# yum install -y openstack-nova-compute sysfsutils # yum install -y openstack-neutron openstack-neutron-linuxbridge ebtables

安裝Keystone服務

openstack 的Keystone 組件提供統一的用戶注冊和驗證服務。keystone服務默認使用的端口為5000.
1、 修改配置文件/etc/keystone/keystone.conf,我們的控制節點為 192.168.10.11

[database] # ... connection = mysql+pymysql://keystone:keystone@192.168.10.11/keystone[token] # ... provider = fernet

2、同步數據庫:

# su -s /bin/sh -c "keystone-manage db_sync" keystone

檢查同步是否成功：

# mysql -ukeystone -pkeystone -e "use keystone;show tables;"

3、初始化：

# keystone-manage fernet_setup --keystone-user keystone --keystone-group keystone # keystone-manage credential_setup --keystone-user keystone --keystone-group keystone

4、啟動服務,指定密碼為admin：

keystone-manage bootstrap --bootstrap-password admin \--bootstrap-admin-url http://192.168.10.11:35357/v3/ \--bootstrap-internal-url http://192.168.10.11:5000/v3/ \--bootstrap-public-url http://192.168.10.11:5000/v3/ \--bootstrap-region-id RegionOne

5、配置Apache httpd,修改配置文件/etc/httpd/conf/httpd.conf: 修改為控制節點的IP

ServerName 192.168.10.11

6、創建軟連接，將keystone的配置鏈接到apache:

ln -s /usr/share/keystone/wsgi-keystone.conf /etc/httpd/conf.d/

7、啟動服務，并設置自啟動

# systemctl enable httpd.service # systemctl start httpd.service

查看5000端口(public endpoint)和35357(admin endpoint)端口是否啟動。
8、設置環境變量：

export OS_USERNAME=adminexport OS_PASSWORD=adminexport OS_PROJECT_NAME=adminexport OS_USER_DOMAIN_NAME=Defaultexport OS_PROJECT_DOMAIN_NAME=Defaultexport OS_AUTH_URL=http://192.168.10.11:35357/v3export OS_IDENTITY_API_VERSION=3

9、創建域，項目，用戶和角色

• 創建一個service 項目：

# openstack project create --domain default --description "Service Project" service +-------------+----------------------------------+ | Field | Value | +-------------+----------------------------------+ | description | Service Project | | domain_id | default | | enabled | True | | id | 1b1aef4a9bda49d59ffa17cbae4d3247 | | is_domain | False | | name | service | | parent_id | default | +-------------+----------------------------------+

• 創建一個demo的項目：

# openstack project create --domain default --description "Demo Project" demo +-------------+----------------------------------+ | Field | Value | +-------------+----------------------------------+ | description | Demo Project | | domain_id | default | | enabled | True | | id | d63f87c94e634aefbdf3fa48d4f43b18 | | is_domain | False | | name | demo | | parent_id | default | +-------------+----------------------------------+

• 創建一個demo的用戶,并設置密碼為 demo：

# openstack user create --domain default --password demo demo +---------------------+----------------------------------+ | Field | Value | +---------------------+----------------------------------+ | domain_id | default | | enabled | True | | id | 8c10323be99e4597a099db1ba3b79627 | | name | demo | | options | {} | | password_expires_at | None | +---------------------+----------------------------------+

• 創建一個用戶角色：

# openstack role create user +-----------+----------------------------------+ | Field | Value | +-----------+----------------------------------+ | domain_id | None | | id | b3fb6198ad97428898db24d04a384e5d | | name | user | +-----------+----------------------------------+

• 將user角色添加到demo項目中，并給demo用戶授予 user角色的權限：

openstack role add --project demo --user demo user

檢查用戶，角色，項目：

# openstack user list +----------------------------------+-------+ | ID | Name | +----------------------------------+-------+ | 8c10323be99e4597a099db1ba3b79627 | demo | | b6656538b5334a1cae296fee65ca122b | admin | +----------------------------------+-------+# openstack role list +----------------------------------+----------+ | ID | Name | +----------------------------------+----------+ | 36e337bdc9c94785b4fce4e5e7cc5710 | admin | | 9fe2ff9ee4384b1894a90878d3e92bab | _member_ | | b3fb6198ad97428898db24d04a384e5d | user | +----------------------------------+----------+# openstack project list +----------------------------------+---------+ | ID | Name | +----------------------------------+---------+ | 0daaf987a867495fa0937a16b359c729 | admin | | 1b1aef4a9bda49d59ffa17cbae4d3247 | service | | d63f87c94e634aefbdf3fa48d4f43b18 | demo | +----------------------------------+---------+

10 . Unset 掉臨時的 OS_AUTH_URL 和 OS_PASSWORD 環境變量，對admin用戶和demo用戶進行驗證:

# unset OS_AUTH_URL OS_PASSWORD

11 . 使用admin 用戶，獲取一個授權的token,使用 --os-password 指定用戶密碼:

# openstack --os-auth-url http://192.168.10.11:35357/v3 --os-project-domain-name Default --os-user-domain-name Default --os-project-name admin --os-username admin --os-password admin token issue +------------+-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+ | Field | Value | +------------+-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+ | expires | 2018-01-09T10:49:13+0000 | | id | gAAAAABaVJAZylB0puTtnl0DoU1rUSkNP4wOM_2CgL7j_rVRy7nowuQRX9LueUVbfR6jjeB4wtAWAfl39oeECgdEaJUrUBvLnpDAIHBP1lf1AVXFDyAYUEisUZFEC4TpULgxvRK7c98PjABWUQO27jY74zi7kdEtEH6J783TKARCpxr42dPFfbM | | project_id | 0daaf987a867495fa0937a16b359c729 | | user_id | b6656538b5334a1cae296fee65ca122b | +------------+-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+

12 . 嘗試使用demo用戶獲取一個token:

# openstack --os-auth-url http://192.168.10.11:5000/v3 --os-project-domain-name Default --os-user-domain-name Default --os-project-name demo --os-username demo --os-password demo token issue +------------+-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+ | Field | Value | +------------+-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+ | expires | 2018-01-09T10:54:39+0000 | | id | gAAAAABaVJFfrjuHz6b6VIKFo59Z_pFF6bzdxmU7y81OhzznZ0QQIwsbiTgPrnCkC4DRBQAQ6uSj-M-kBQURHAwxHRhCvGxikhcNtsgLTH5d4xy_QIWLmAGapB90Gvykbqjz4EGjYTGWYT2vYg8K1fGiglNJZS8C-fqP6YDmDAQFLkaNVrqcs6Y | | project_id | d63f87c94e634aefbdf3fa48d4f43b18 | | user_id | 8c10323be99e4597a099db1ba3b79627 | +------------+-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+

13 . 驗證成功后，可以將admin和demo用戶指定的參數使用環境變量的方式寫到文件中，在使用不同用戶進行操作時，就先執行此環境變量：

# cat admin-openstack.sh export OS_PROJECT_DOMAIN_NAME=Default export OS_USER_DOMAIN_NAME=Default export OS_PROJECT_NAME=admin export OS_USERNAME=admin export OS_PASSWORD=admin export OS_AUTH_URL=http://192.168.10.11:35357/v3 export OS_IDENTITY_API_VERSION=3 export OS_IMAGE_API_VERSION=2 # cat demo-openstack.sh export OS_PROJECT_DOMAIN_NAME=Default export OS_USER_DOMAIN_NAME=Default export OS_PROJECT_NAME=demo export OS_USERNAME=demo export OS_PASSWORD=demo export OS_AUTH_URL=http://192.168.10.11:5000/v3 export OS_IDENTITY_API_VERSION=3 export OS_IMAGE_API_VERSION=2

通過執行 source admin-openstack.sh 和 source demo-openstack.sh 來獲取token ,確保獲取成功。

# source admin-openstack.sh # openstack token issue ... # source demo-openstack.sh # openstack token issue ...

查看服務：

[root@openstack-node1 ~]# source admin-openstack.sh [root@openstack-node1 ~]# openstack service list +----------------------------------+----------+----------+ | ID | Name | Type | +----------------------------------+----------+----------+ | 5f6ad425ca88486083910af1cf7d2684 | keystone | identity | +----------------------------------+----------+----------+

配置鏡像服務Glance

1、創建一個glance的用戶，設置密碼為glance：

# openstack user create --domain default --password glance glance +---------------------+----------------------------------+ | Field | Value | +---------------------+----------------------------------+ | domain_id | default | | enabled | True | | id | d42073f41d3240db9db27ab493be3495 | | name | glance | | options | {} | | password_expires_at | None | +---------------------+----------------------------------+

2、 將 glance用戶添加到 Service 項目，并授予 admin的角色權限：

# openstack role add --project service --user glance admin

3、 創建一個glance的服務：

# openstack service create --name glance --description "OpenStack Image" image +-------------+----------------------------------+ | Field | Value | +-------------+----------------------------------+ | description | OpenStack Image | | enabled | True | | id | 9627ac8da083454cb644916a5a30525e | | name | glance | | type | image | +-------------+----------------------------------+

4、創建鏡像服務的api ,endpoint。這里的endpoint實際上就是一個URL鏈接,分別為public、internal、admin。

# openstack endpoint create --region RegionOne image public http://192.168.10.11:9292 +--------------+----------------------------------+ | Field | Value | +--------------+----------------------------------+ | enabled | True | | id | 4d62369819b8441bbc73b5093b397093 | | interface | public | | region | RegionOne | | region_id | RegionOne | | service_id | 9627ac8da083454cb644916a5a30525e | | service_name | glance | | service_type | image | | url | http://192.168.10.11:9292 | +--------------+----------------------------------+# openstack endpoint create --region RegionOne image internal http://192.168.10.11:9292 +--------------+----------------------------------+ | Field | Value | +--------------+----------------------------------+ | enabled | True | | id | 08f7962c2f544591af7ebd7e8c01a50a | | interface | internal | | region | RegionOne | | region_id | RegionOne | | service_id | 9627ac8da083454cb644916a5a30525e | | service_name | glance | | service_type | image | | url | http://192.168.10.11:9292 | +--------------+----------------------------------+# openstack endpoint create --region RegionOne image admin http://192.168.10.11:9292 +--------------+----------------------------------+ | Field | Value | +--------------+----------------------------------+ | enabled | True | | id | 62d31d33d7b949ddb37960d5dfb04133 | | interface | admin | | region | RegionOne | | region_id | RegionOne | | service_id | 9627ac8da083454cb644916a5a30525e | | service_name | glance | | service_type | image | | url | http://192.168.10.11:9292 | +--------------+----------------------------------+

5、修改glance配置，在 /etc/glance/glance-api.conf 中配置如下選項：

# egrep -v "^#|^$" /etc/glance/glance-api.conf[database] connection = mysql+pymysql://glance:glance@192.168.10.11/glance [glance_store] stores = file,http default_store = file filesystem_store_datadir = /var/lib/glance/images[keystone_authtoken] auth_uri = http://192.168.10.11:5000 auth_url = http://192.168.10.11:35357 memcached_servers = 192.168.10.11:11211 auth_type = password project_domain_name = default user_domain_name = default project_name = service username = glance password = glance[paste_deploy] flavor = keystone

6、修改 /etc/glance/glance-registry.conf 文件配置：

# egrep -v "^#|^$" /etc/glance/glance-registry.conf [database] connection = mysql+pymysql://glance:glance@192.168.10.11/glance [keystone_authtoken] auth_uri = http://192.168.10.11:5000 auth_url = http://192.168.10.11:35357 memcached_servers = 192.168.10.11:11211 auth_type = password project_domain_name = default user_domain_name = default project_name = service username = glance password = glance [paste_deploy] flavor = keystone

6、 同步數據庫:

# su -s /bin/sh -c "glance-manage db_sync" glance

7、啟動服務：

# systemctl enable openstack-glance-api.service openstack-glance-registry.service # systemctl start openstack-glance-api.service openstack-glance-registry.service

glance-api監聽 9292端口， glance-registry 監聽9191端口,可以通過如下命令查看：

ps aux|grep PID

8、對服務進行驗證。下載示例的小鏡像：

# source admin-openstack.sh # wget http://download.cirros-cloud.net/0.3.5/cirros-0.3.5-x86_64-disk.img

9、 添加此鏡像到鏡像服務，使用QCOW2的格式，容器格式為bare，指定權限為public：

# openstack image create "cirros" --file cirros-0.3.5-x86_64-disk.img --disk-format qcow2 --container-format bare --public +------------------+------------------------------------------------------+ | Field | Value | +------------------+------------------------------------------------------+ | checksum | f8ab98ff5e73ebab884d80c9dc9c7290 | | container_format | bare | | created_at | 2018-01-09T11:27:25Z | | disk_format | qcow2 | | file | /v2/images/dc655534-2821-47c1-b9c4-8687b52dfdbc/file | | id | dc655534-2821-47c1-b9c4-8687b52dfdbc | | min_disk | 0 | | min_ram | 0 | | name | cirros | | owner | 0daaf987a867495fa0937a16b359c729 | | protected | False | | schema | /v2/schemas/image | | size | 13267968 | | status | active | | tags | | | updated_at | 2018-01-09T11:27:26Z | | virtual_size | None | | visibility | public | +------------------+------------------------------------------------------+

10、 查看鏡像：

# openstack image list +--------------------------------------+--------+--------+ | ID | Name | Status | +--------------------------------------+--------+--------+ | dc655534-2821-47c1-b9c4-8687b52dfdbc | cirros | active | +--------------------------------------+--------+--------+

控制節點配置 nova 服務

1、創建nova 用戶，設置密碼為nova：

7、創建placement的服務：

# openstack service create --name placement --description "Placement API" placement +-------------+----------------------------------+ | Field | Value | +-------------+----------------------------------+ | description | Placement API | | enabled | True | | id | df983a5c65d0458a8ddc93ffebf49f92 | | name | placement | | type | placement | +-------------+----------------------------------+

8、創建placement api endpoint,指定 public ，internal，admin：

# openstack endpoint create --region RegionOne placement public http://192.168.10.11:8778 +--------------+----------------------------------+ | Field | Value | +--------------+----------------------------------+ | enabled | True | | id | 77e40ae383774440a1d26c749205a019 | | interface | public | | region | RegionOne | | region_id | RegionOne | | service_id | df983a5c65d0458a8ddc93ffebf49f92 | | service_name | placement | | service_type | placement | | url | http://192.168.10.11:8778 | +--------------+----------------------------------+# openstack endpoint create --region RegionOne placement internal http://192.168.10.11:8778 +--------------+----------------------------------+ | Field | Value | +--------------+----------------------------------+ | enabled | True | | id | 78a4e9b6032a4174a2d4854a93305a1e | | interface | internal | | region | RegionOne | | region_id | RegionOne | | service_id | df983a5c65d0458a8ddc93ffebf49f92 | | service_name | placement | | service_type | placement | | url | http://192.168.10.11:8778 | +--------------+----------------------------------+# openstack endpoint create --region RegionOne placement admin http://192.168.10.11:8778 +--------------+----------------------------------+ | Field | Value | +--------------+----------------------------------+ | enabled | True | | id | 7d975e3e5d8c4952a6a96903e5e6a36b | | interface | admin | | region | RegionOne | | region_id | RegionOne | | service_id | df983a5c65d0458a8ddc93ffebf49f92 | | service_name | placement | | service_type | placement | | url | http://192.168.10.11:8778 | +--------------+----------------------------------+

9、修改 nova 配置文件 /etc/nova/nova.conf :

# egrep -v "^$|^#" /etc/nova/nova.conf[DEFAULT] use_neutron=true firewall_driver=nova.virt.firewall.NoopFirewallDriver enabled_apis=osapi_compute,metadata transport_url=rabbit://openstack:openstack@192.168.10.11 [api] auth_strategy=keystone [api_database] connection=mysql+pymysql://nova:nova@192.168.10.11/nova_api[database] connection=mysql+pymysql://nova:nova@192.168.10.11/nova[glance] api_servers=http://192.168.10.11:9292[keystone_authtoken] auth_uri = http://192.168.10.11:5000 auth_url = http://192.168.10.11:35357 memcached_servers = 192.168.10.11:11211 auth_type = password project_domain_name = default user_domain_name = default project_name = service username = nova password = nova[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://192.168.10.11:35357/v3 username = placement password = placement[vnc] enabled=true vncserver_listen=192.168.10.11 vncserver_proxyclient_address=192.168.10.11

10、對軟件包的 bug修復，需要添加如下內容到 /etc/httpd/conf.d/00-nova-placement-api.conf文件中（添加到虛擬主機中）：

<Directory /usr/bin><IfVersion >= 2.4>Require all granted</IfVersion><IfVersion < 2.4>Order allow,denyAllow from all</IfVersion> </Directory>

11、 重啟 httpd的服務：

# systemctl restart httpd

12、 同步nova-api數據：

su -s /bin/sh -c "nova-manage api_db sync" nova

13、注冊cell0：

# su -s /bin/sh -c "nova-manage cell_v2 map_cell0" nova

14 、創建 cell1：

su -s /bin/sh -c "nova-manage cell_v2 create_cell --name=cell1 --verbose" nova eab4a5f9-04fb-40fa-bf78-c6cd75ab93b1

15、 同步nova 數據庫：

# su -s /bin/sh -c "nova-manage db sync" nova

16、 查看cell和cell是否注冊成功。

# nova-manage cell_v2 list_cells +-------+--------------------------------------+ | Name | UUID | +-------+--------------------------------------+ | cell1 |ddc4df46-fd96-4778-b312-95e8ad37e3d3 | | cell0 | 00000000-0000-0000-0000-000000000000 | +-------+--------------------------------------+

17、啟動服務：

# systemctl enable openstack-nova-api.service \openstack-nova-consoleauth.service openstack-nova-scheduler.service \openstack-nova-conductor.service openstack-nova-novncproxy.service # systemctl start openstack-nova-api.service \openstack-nova-consoleauth.service openstack-nova-scheduler.service \openstack-nova-conductor.service openstack-nova-novncproxy.service

驗證控制節點服務

查看各個服務狀態：
