OpenStack系列（四）：controller节点部署08【nova安装配置】

在控制节点上，nova-api负责虚拟机生命周期的操作，nova-scheduler实现控制在哪个计算节点上启动实例，nova-conductor主要是防止云端上计算节点直接访问数据库。需要明确的一点是，控制节点上没有提供计算资源虚拟化功能，都是由计算节点上的nova-compute来完成供给实例计算资源。

1）在controller1上创建nova数据库

MariaDB [(none)]> CREATE DATABASE nova;
MariaDB [(none)]> CREATE DATABASE nova_api;


2）在controller1创建数据库用户并赋予权限

MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'localhost' IDENTIFIED BY 'yjscloud';
MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'%' IDENTIFIED BY 'yjscloud';
MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'localhost' IDENTIFIED BY 'yjscloud';
MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'%' IDENTIFIED BY 'yjscloud';


3）在controller1上创建nova用户及赋予admin权限

source /root/admin-openrc
openstack user create --domain default nova --password yjscloud
openstack role add --project service --user nova admin


4）在controller1上创建computer服务

openstack service create --name nova --description "OpenStack Compute" compute


5）在controller1创建nova的endpoint

openstack endpoint create --region RegionOne compute public http://blog.yjscloud.com:8774/v2.1/%\(tenant_id\)s
openstack endpoint create --region RegionOne compute internal http://blog.yjscloud.com:8774/v2.1/%\(tenant_id\)s
openstack endpoint create --region RegionOne compute admin http://blog.yjscloud.com:8774/v2.1/%\(tenant_id\)s


6）在controller1、2、3上安装nova相关软件

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

7）在controller1、2、3上配置nova的配置文件/etc/nova/nova.conf

scp -p /etc/nova/nova.conf controller2:/etc/nova/nova.conf 
scp -p /etc/nova/nova.conf controller3:/etc/nova/nova.conf 

注意修改ip

8）在controller1同步nova数据

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


9）在controller1上设置开机启动

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


controller2、3上设置开机启动（注意比controller1节点少了openstack-nova-consoleauth.service）：

systemctl enable openstack-nova-api.service openstack-nova-cert.service openstack-nova-scheduler.service openstack-nova-conductor.service openstack-nova-novncproxy.service


controller1上启动nova服务：

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

systemctl status openstack-nova-api.service openstack-nova-cert.service openstack-nova-consoleauth.service openstack-nova-scheduler.service openstack-nova-conductor.service openstack-nova-novncproxy.service

controller2、3上启动nova服务：

systemctl restart openstack-nova-api.service openstack-nova-cert.service openstack-nova-scheduler.service openstack-nova-conductor.service openstack-nova-novncproxy.service

systemctl status openstack-nova-api.service openstack-nova-cert.service openstack-nova-scheduler.service openstack-nova-conductor.service openstack-nova-novncproxy.service

systemctl list-unit-files | grep openstack-noca-*

10）随便一个节点上验证nova服务

unset OS_TOKEN OS_URL
echo "export OS_REGION_NAME=RegionOne" >> admin-openrc
source /root/admin-openrc
nova service-list
openstack endpoint list
