openstack私有云布署实践【10.1 计算nova - kxcontroller节点配置（科兴环境）】

一、首先登录kxcontroller1创建kx_nova数据库，并赋于远程和本地访问的权限。

 

 

mysql -u root -p

 

CREATE DATABASE kx_nova;

GRANT ALL PRIVILEGES ON kx_nova.* TO 'nova'@'localhost'  IDENTIFIED BY 'venic8888';

GRANT ALL PRIVILEGES ON kx_nova.* TO 'nova'@'%'  IDENTIFIED BY 'venic8888';

flush PRIVILEGES;

 

 

二、身份认证调用

使用1台kxcontroller1创建身份认证调用

 

source admin-openrc.sh

 

openstack user create --domain default --password-prompt nova

User Password:

Repeat User Password:

三、下载安装nova组件

2台kxcontroller

yum install openstack-nova-api openstack-nova-cert openstack-nova-conductor openstack-nova-console openstack-nova-novncproxy openstack-nova-scheduler python-novaclient -y

 

2台kxcontroller配置nova配置文件

 

在kxcontroller1上

vi /etc/nova/nova.conf

[DEFAULT]

resume_guests_state_on_host_boot=True

rpc_backend = rabbit

auth_strategy = keystone

my_ip = 10.120.42.1

enabled_apis=osapi_compute,metadata

verbose = True

 

ram_allocation_ratio = 1.0

allow_resize_to_same_host=true

allow_migrate_to_same_host=true

resize_confirm_window=1

 

dhcp_domain =

 

network_api_class = nova.network.neutronv2.api.API

security_group_api = neutron

linuxnet_interface_driver = nova.network.linux_net.NeutronLinuxBridgeInterfaceDriver

firewall_driver = nova.virt.firewall.NoopFirewallDriver

 

osapi_compute_listen = 10.120.42.1

osapi_compute_listen_port = 8774

metadata_listen  = 10.120.42.1

metadata_listen_port = 8775

novncproxy_host = 10.120.42.1

novncproxy_port = 6080

 

[database]

connection = mysql://nova:venic8888@kxcontroller/kx_nova

 

[keystone_authtoken]

auth_uri = http://kxcontroller:5000

auth_url = http://kxcontroller:35357

auth_plugin = password

project_domain_id = default

user_domain_id = default

project_name = service

username = nova

password = nova

 

[vnc]

vncserver_listen = $my_ip

vncserver_proxyclient_address = $my_ip

 

[glance]

host = kxcontroller

 

[oslo_concurrency]

lock_path = /var/lib/nova/tmp

 

[oslo_messaging_rabbit]

rabbit_host=kxcontroller

rabbit_userid = openstack

rabbit_password = openstack

 

[neutron]

url = http://kxcontroller:9696

auth_url = http://kxcontroller:35357

auth_plugin = password

project_domain_id = default

user_domain_id = default

region_name = RegionTwo

project_name = service

username = neutron

password = neutron

 

service_metadata_proxy = True

metadata_proxy_shared_secret = venicchina

 

以上的紫色配置原本是要等配neutron时再加的，只是这里我提前贴出来了以便做全局维护 ，如果你们是新搭环境的话，这个紫色配置要等安装了neutron包再加

 

 

在kxcontroller2上

vi /etc/nova/nova.conf

 

[DEFAULT]

rpc_backend = rabbit

auth_strategy = keystone

my_ip = 10.120.42.2

enabled_apis=osapi_compute,metadata

verbose = True

 

ram_allocation_ratio = 1.0

allow_resize_to_same_host=true

allow_migrate_to_same_host=true

resize_confirm_window=1

 

dhcp_domain =

 

network_api_class = nova.network.neutronv2.api.API

security_group_api = neutron

linuxnet_interface_driver = nova.network.linux_net.NeutronLinuxBridgeInterfaceDriver

firewall_driver = nova.virt.firewall.NoopFirewallDriver

 

osapi_compute_listen = 10.120.42.2

osapi_compute_listen_port = 8774

metadata_listen  = 10.120.42.2

metadata_listen_port = 8775

novncproxy_host = 10.120.42.2

novncproxy_port = 6080

 

[database]

connection = mysql://nova:venic8888@kxcontroller/kx_nova

 

[keystone_authtoken]

auth_uri = http://kxcontroller:5000

auth_url = http://kxcontroller:35357

auth_plugin = password

project_domain_id = default

user_domain_id = default

project_name = service

username = nova

password = nova

 

[vnc]

vncserver_listen = $my_ip

vncserver_proxyclient_address = $my_ip

 

[glance]

host = kxcontroller

 

[oslo_concurrency]

lock_path = /var/lib/nova/tmp

 

[oslo_messaging_rabbit]

rabbit_host=kxcontroller

rabbit_userid = openstack

rabbit_password = openstack

 

[neutron]

url = http://kxcontroller:9696

auth_url = http://kxcontroller:35357

auth_plugin = password

project_domain_id = default

user_domain_id = default

region_name = RegionTwo

project_name = service

username = neutron

password = neutron

 

service_metadata_proxy = True

metadata_proxy_shared_secret = venicchina

 

 

以上的紫色配置原本是要等配neutron时再加的，只是这里我提前贴出来了以便做全局维护 ，如果你们是新搭环境的话，这个紫色配置要等安装了neutron包再加

 

 

其中一台controller 同步数据库

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

 

两台controller 开启服务，以及加入开机自启

 

# systemctl enable openstack-nova-api.service \

  openstack-nova-cert.service openstack-nova-consoleauth.service \

  openstack-nova-scheduler.service openstack-nova-conductor.service \

  openstack-nova-novncproxy.service

 

# systemctl restart openstack-nova-api.service \

  openstack-nova-cert.service openstack-nova-consoleauth.service \

  openstack-nova-scheduler.service openstack-nova-conductor.service \

  openstack-nova-novncproxy.service
