openstack搭建之-nova配置（10）

一、 base节点设置数据库

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节点设置配置

#控制节点运行环境变量

. admin-openrc

#创建nova用户并添加角色为admin

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

openstack role add --project service --user nova admin

#创建nova服务项目并设置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

#创建placement用户并加入角色为admin

openstack user create --domain default --password PLACEMENT_PASS placement

openstack role add --project service --user placement admin

#创建placement服务并设置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

#编辑Nova-placement-api配置文件

vim /etc/httpd/conf.d/00-nova-placement-api.conf

<Directory /usr/bin>

systemctl restart httpd

#初始化nova-api数据库

su -s /bin/sh -c "nova-manage api_db sync" nova

#填充cell0数据库

su -s /bin/sh -c "nova-manage cell_v2 map_cell0" nova

#创建cell1

su -s /bin/sh -c "nova-manage cell_v2 create_cell --name=cell1 --verbose" nova

#初始化Nova数据库

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

#验证cell0和cell2是否注册正确

#开启Nova服务

systemctl restart \

openstack-nova-api.service \

openstack-nova-consoleauth.service \

openstack-nova-scheduler.service \

openstack-nova-conductor.service \

openstack-nova-novncproxy.service

systemctl status \

三、 Nova-computer计算节点配置

#配置网卡1（eth0）

IP=172.16.2.53

DNS=172.16.2.53

网关=172.16.0.1

#安装KVM软件

yum install qemu-kvm* virt-* libvirt* spice* -y

lsmod | grep kvm

systemctl start libvirtd

systemctl status libvirtd

systemctl enable libvirtd

#配置网卡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

#安装Nova软件，并编辑配置文件

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
auth_url = http://ctrl.test.com:35357/v3
memcached_servers = base.test.com:
auth_type = password
project_domain_name = default
user_domain_name = default

username = nova
password = NOVA_PASS

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

[glance]

#开启服务

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控制节点查看

#ctrl节点运行环境变量

. admin-openrc

#查看相关信息

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
