Openstack（十）部署nova服務（計算節點）

 

 

 

在計算節點安裝

10.1安裝nova計算服務

# 阿里雲源詳見2.3配置

# yum install openstack-nova-compute

10.2配置nova計算服務

10.2.1配置nova.conf

# vim /etc/nova/nova.conf

1:[DEFAULT]

2306:use_neutron=true

2465:firewall_driver=nova.virt.firewall.NoopFirewallDriver

2629:enabled_apis=osapi_compute,metadata

3021:transport_url = rabbit://openstack:123456@192.168.10.205

3069:[api]

3085:auth_strategy=keystone

4937:[glance]

4955:api_servers=http://192.168.10.100:9292

5596:[keystone_authtoken]

5597:auth_uri = http://192.168.10.100:5000

5598:auth_url = http://192.168.10.100:35357

5599:memcached_servers = 192.168.10.100:11211

5600:auth_type = password

5601:project_domain_name = default

5602:user_domain_name = default

5603:project_name = service

5604:username = nova

5605:password = nova

8082:project_name = service

8083:auth_type = password

8084:user_domain_name = Default

8085:auth_url = http://192.168.10.100:35357/v3

8086:username = placement

8087:password = placement

9667:[vnc]

9683:enabled=true

9706:vncserver_listen=0.0.0.0

10.2.2確認計算節點是否支持硬件加速

# egrep -c '(vmx|svm)' /proc/cpuinfo

40

10.3啓動nova計算服務並設置爲開機啓動

# systemctl enable libvirtd.service openstack-nova-compute.service

# systemctl start libvirtd.service openstack-nova-compute.service

10.4添加計算服務到cell數據庫

# 在控制端配置

# source  admin-openstack.sh

#按期主動發現：

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

# openstack hypervisor list

+----+-------------------------+-----------------+----------------+-------+

| ID | Hypervisor Hostname     | Hypervisor Type | Host IP        | State |

+----+-------------------------+-----------------+----------------+-------+

|  1 | linux-host2.exmaple.com | QEMU            | 192.168.10.202 | up    |

+----+-------------------------+-----------------+----------------+-------+

# 設置按期主動發現

# vim /etc/nova/nova.conf

8577 [scheduler]

8684 discover_hosts_in_cells_interval=300

#重啓nova服務

# bash nova- restart.sh

10.5驗證計算節點

# nova host-list

# nova service-list

# openstack image list

#  openstack compute service list

#列出服務組件是否成功註冊

# nova-status upgrade check

# openstack catalog list

#列出keystone服務中的端點，以驗證keystone的連通性
