一、 base節點設置數據庫
mysql -u root -proot
CREATE DATABASE nova_api;
CREATE DATABASE nova;
CREATE DATABASE nova_cell0;
GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'localhost' IDENTIFIED BY 'NOVA_DBPASS';
GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'%' IDENTIFIED BY 'NOVA_DBPASS';
GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'localhost' IDENTIFIED BY 'NOVA_DBPASS';
GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'%' IDENTIFIED BY 'NOVA_DBPASS';
GRANT ALL PRIVILEGES ON nova_cell0.* TO 'nova'@'localhost' IDENTIFIED BY 'NOVA_DBPASS';
GRANT ALL PRIVILEGES ON nova_cell0.* TO 'nova'@'%' IDENTIFIED BY 'NOVA_DBPASS';
二、 ctrl節點設置配置
#控制節點運行環境變量
. admin-openrc
#創建nova用戶並添加角色為admin
openstack user create --domain default --password NOVA_PASS nova
openstack role add --project service --user nova admin
#創建nova服務項目並設置endpoint
openstack service create --name nova --description "OpenStack Compute" compute
openstack endpoint create --region RegionOne compute public http://ctrl.test.com:8774/v2.1
openstack endpoint create --region RegionOne compute internal http://ctrl.test.com:8774/v2.1
openstack endpoint create --region RegionOne compute admin http://ctrl.test.com:8774/v2.1
#創建placement用戶並加入角色為admin
openstack user create --domain default --password PLACEMENT_PASS placement
openstack role add --project service --user placement admin
#創建placement服務並設置endpoint
openstack service create --name placement --description "Placement API" placement
openstack endpoint create --region RegionOne placement public http://ctrl.test.com:8778
openstack endpoint create --region RegionOne placement internal http://ctrl.test.com:8778
openstack endpoint create --region RegionOne placement admin http://ctrl.test.com:8778

三、 Nova-computer計算節點配置
#配置網卡1（eth0）
IP=172.16.2.53
DNS=172.16.2.53
網關=172.16.0.1
#安裝KVM軟件
yum install qemu-kvm* virt-* libvirt* spice* -y
lsmod | grep kvm
systemctl start libvirtd
systemctl status libvirtd
systemctl enable libvirtd
#配置網卡2（eth1）
vim /etc/sysconfig/network-scripts/ifcfg-eth1
TYPE=Ethernet BOOTPROTO=none NAME=eth1 DEVICE=eth1 ONBOOT=yes UUID=5fb06bd0-0bb0-7ffb-45f1-d6edd65f3e03
#安裝Nova軟件，並編輯配置文件
yum install openstack-nova-compute -y
vim /etc/nova/nova.conf
[DEFAULT] enabled_apis = osapi_compute,metadata transport_url = rabbit://openstack:RABBIT_PASS@base.test.com
my_ip = 172.16.2.53 use_neutron = True firewall_driver = nova.virt.firewall.NoopFirewallDriver [api] auth_strategy = keystone [keystone_authtoken] auth_uri = http://ctrl.test.com:5000/v3

[glance] api_servers = http://ctrl.test.com:9292
[oslo_concurrency] lock_path = /var/lib/nova/tmp [placement] os_region_name = RegionOne project_domain_name = Default project_name = service auth_type = password user_domain_name = Default auth_url = http://ctrl.test.com:5000/v3
username = placement password = PLACEMENT_PASS
#開啟服務
systemctl restart libvirtd.service openstack-nova-compute.service
systemctl status libvirtd.service openstack-nova-compute.service
systemctl enable libvirtd.service openstack-nova-compute.service
四、ctrl控制節點查看
#ctrl節點運行環境變量
. admin-openrc
#查看相關信息
openstack hypervisor list
su -s /bin/sh -c "nova-manage cell_v2 discover_hosts --verbose" nova
openstack compute service list
openstack catalog list
openstack image list
