控制节点的配置

建立数据库

在controller节点上

mysql -u root -p
mysql> CREATE DATABASE nova_api;
mysql> CREATE DATABASE nova;
mysql> GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'localhost' \
  IDENTIFIED BY 'NOVA_DBPASS';
mysql> GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'%' \
  IDENTIFIED BY 'NOVA_DBPASS';
mysql> GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'localhost' \
  IDENTIFIED BY 'NOVA_DBPASS';
mysql> GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'%' \
  IDENTIFIED BY 'NOVA_DBPASS';

创建openstack用户

使用admin环境变量脚本，创建openstack用户nova

openstack user create --domain default \
  --password-prompt nova
openstack role add --project service --user nova admin
openstack service create --name nova \
  --description "OpenStack Compute" compute
openstack endpoint create --region RegionOne \
  compute public http://controller:8774/v2.1/%\(tenant_id\)s
openstack endpoint create --region RegionOne \
  compute internal http://controller:8774/v2.1/%\(tenant_id\)s
openstack endpoint create --region RegionOne \
  compute admin http://controller:8774/v2.1/%\(tenant_id\)s

安装配置nova

在controller节点上，

 yum install openstack-nova-api openstack-nova-conductor \
  openstack-nova-console openstack-nova-novncproxy \
  openstack-nova-scheduler

编辑/etc/nova/nova.conf,修改或添加如下条目

[DEFAULT]
...
enabled_apis = osapi_compute,metadata
transport_url = rabbit://openstack:RABBIT_PASS@controller
auth_strategy = keystone
my_ip = 10.0.0.101
use_neutron = True
firewall_driver = nova.virt.firewall.NoopFirewallDriver
[api_database]
...
connection = mysql+pymysql://nova:NOVA_DBPASS@controller/nova_api

[database]
...
connection = mysql+pymysql://nova:NOVA_DBPASS@controller/nova

[keystone_authtoken]
...
auth_uri = http://controller:5000
auth_url = http://controller:35357
memcached_servers = controller:11211
auth_type = password
project_domain_name = Default
user_domain_name = Default
project_name = service
username = nova
password = NOVA_PASS

[vnc]
...
vncserver_listen = $my_ip
vncserver_proxyclient_address = $my_ip

[glance]
...
api_servers = http://controller:9292

[oslo_concurrency]
...
lock_path = /var/lib/nova/tmp

nova信息同步到数据库

/bin/sh -c "nova-manage api_db sync" nova
/bin/sh -c "nova-manage db sync" nova

开机启动nova服务

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

计算节点的配置

安装nova

yum install openstack-nova-compute

编辑配置文件/etc/nova/nova.conf,添加或更改如下条目

[DEFAULT]
...
enabled_apis = osapi_compute,metadata
transport_url = rabbit://openstack:RABBIT_PASS@controller
auth_strategy = keystone
my_ip = MANAGEMENT_INTERFACE_IP_ADDRESS
use_neutron = True
firewall_driver = nova.virt.firewall.NoopFirewallDriver

[keystone_authtoken]
...
auth_uri = http://controller:5000
auth_url = http://controller:35357
memcached_servers = controller:11211
auth_type = password
project_domain_name = Default
user_domain_name = Default
project_name = service
username = nova
password = NOVA_PASS

[vnc]
...
enabled = True
vncserver_listen = 0.0.0.0
vncserver_proxyclient_address = $my_ip
novncproxy_base_url = http://controller:6080/vnc_auto.html

[glance]
...
api_servers = http://controller:9292

[oslo_concurrency]
...
lock_path = /var/lib/nova/tmp

# 如果该节点不支持虚拟化，则需要使用QEMU代替KVM
# 需要添加如下条目
[libvirt]
...
virt_type = qemu

设置开机启动

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

验证操作

在controller节点上查看计算节点,使用admin的环境变量脚本，运行下面命令

openstack compute service list
