openstack安装--nova

在controller节点操作

创建Nova数据库

mysql -u root -pzouhuiying
CREATE DATABASE nova;
GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'localhost' IDENTIFIED BY 'NOVA_DBPASS';
GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'%' IDENTIFIED BY 'NOVA_DBPASS';
flush privileges

添加环境变量（临时加的环境变量，只在当前的窗口有效）

source admin-openrc.sh

创建Nova用户

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

Add the admin role to the nova user:

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

Create the nova service entity:

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

Create the Compute service API endpoints:

openstack endpoint create --region RegionOne compute public http://controller:8774/v2/%\(tenant_id\)s
openstack endpoint create --region RegionOne compute internal http://controller:8774/v2/%\(tenant_id\)s
openstack endpoint create --region RegionOne compute admin http://controller:8774/v2/%\(tenant_id\)s

同步Nova数据库

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

设置开机自动启动/启动服务

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 start openstack-nova-api.service openstack-nova-cert.service openstack-nova-consoleauth.service openstack-nova-scheduler.service openstack-nova-conductor.service openstack-nova-novncproxy.service

以下是在compute节点安装
安装openstack-nova-compute服务

yum install openstack-nova-compute sysfsutils

vim /etc/nova/nova.conf

判断本台虚拟机是否支持kvm，0：不支持，>=1支持

egrep -c '(vmx|svm)' /proc/cpuinfo

vim /etc/nova/nova.conf

[libvirt]
...
virt_type = qemu //不支持kvm的要用qemu

启动服务

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

遇到的错误：
AMQP server on controller:5672 is unreachable
解决办法：查看controller节点的5672端口没起来，5672是rabbitmq的端口。检查原因是controller节点忘记装了rabbitmq，因为Nova要用到该服务
AMQP server on controller:5672 is unreachable
该服务虽然开启但是没有权限访问
解决办法赋予权限

rabbitmqctl add_user openstack zouhuiying
rabbitmqctl set_permissions openstack ".*" ".*" ".*"
