安裝配置nova
安裝nova服務軟體包
root@controller ~(keystone)# apt -y install nova-api nova-placement-api nova-conductor nova-consoleauth nova-scheduler nova-novncproxy python-novaclient
配置nova，由于官方組態檔修改較為麻煩，這里直接創建一個新的組態檔
root@controller ~(keystone)# mv /etc/nova/nova.conf /etc/nova/nova.conf.org
root@controller ~(keystone)# vi /etc/nova/nova.conf
# 添加以下內容，保存退出
[DEFAULT]
# 設定控制節點IP
my_ip = 10.0.0.7
state_path = /var/lib/nova
enabled_apis = osapi_compute,metadata
log_dir = /var/log/nova
transport_url = rabbit://openstack:root@controller
[api]
auth_strategy = keystone
[glance]
api_servers = http://controller:9292
[oslo_concurrency]
lock_path = $state_path/tmp
[api_database]
connection = mysql+pymysql://nova:root@controller/nova_api
[database]
connection = mysql+pymysql://nova:root@controller/nova
[keystone_authtoken]
auth_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 = root
[placement]
auth_url = http://controller:5000
os_region_name = RegionOne
auth_type = password
project_domain_name = default
user_domain_name = default
project_name = service
username = placement
password = root
[placement_database]
connection = mysql+pymysql://nova:root@controller/nova_placement
[wsgi]
api_paste_config = /etc/nova/api-paste.ini
因為組態檔是新建的，這里把權限加回去
root@controller ~(keystone)# chmod 640 /etc/nova/nova.conf
root@controller ~(keystone)# chgrp nova /etc/nova/nova.conf
初始化資料庫
可能耗時比較長
root@controller:~(keystone)# su -s /bin/bash nova -c "nova-manage api_db sync"
root@controller:~(keystone)# su -s /bin/bash nova -c "nova-manage cell_v2 map_cell0"
root@controller:~(keystone)# su -s /bin/bash nova -c "nova-manage db sync"
root@controller:~(keystone)# su -s /bin/bash nova -c "nova-manage cell_v2 create_cell --name cell1"
重啟apache2服務
root@controller ~(keystone)# systemctl restart apache2
重啟nova相關服務
root@controller ~(keystone)# systemctl restart nova-api
root@controller ~(keystone)# systemctl restart nova-conductor
root@controller ~(keystone)# systemctl restart nova-scheduler
root@controller ~(keystone)# systemctl restart nova-consoleauth
root@controller ~(keystone)# systemctl restart nova-novncproxy
查看nova服務狀態
root@controller ~(keystone)# openstack compute service list
