Openstack（十）部署nova服务（计算节点）

在计算节点安装

10.1安装nova计算服务

# 阿里云源详见2.3配置

# yum install openstack-nova-compute

10.2配置nova计算服务

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

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确认计算节点是否支持硬件加速

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

40

10.3启动nova计算服务并设置为开机启动

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

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

10.4添加计算服务到cell数据库

# 在控制端配置

# source  admin-openstack.sh

#定期主动发现：

# 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    |

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

# 设置定期主动发现

# vim /etc/nova/nova.conf

8577 [scheduler]

8684 discover_hosts_in_cells_interval=300

#重启nova服务

# bash nova- restart.sh

10.5验证计算节点

# nova host-list

# nova service-list

# openstack image list

#  openstack compute service list

#列出服务组件是否成功注册

# nova-status upgrade check

# openstack catalog list

#列出keystone服务中的端点，以验证keystone的连通性
