OpenStack Train版-5.安装nova计算服务（控制节点）

nova计算服务需要在 控制节点 和 计算节点 都安装

控制节点主要安装

​ nova-api（nova主服务）
​ nova-scheduler（nova调度服务）
​ nova-conductor（nova数据库服务，提供数据库访问）
​ nova-novncproxy（nova的vnc服务，提供实例的控制台）

计算节点主要安装
nova-compute（nova计算服务）

安装nova计算服务（controller控制节点192.168.0.10）
创建nova_api，nova和nova_cell0数据库并授权

mysql -uroot
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';
flush privileges;

创建nova用户

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

向nova用户添加admin角色

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

创建nova服务实体

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

创建Compute API服务端点

openstack endpoint create --region RegionOne compute public http://controller:8774/v2.1
openstack endpoint create --region RegionOne compute internal http://controller:8774/v2.1
openstack endpoint create --region RegionOne compute admin http://controller:8774/v2.1

安装nova软件包

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

编辑nova服务的配置文件/etc/nova/nova.conf

cp -a /etc/nova/nova.conf{,.bak}
grep -Ev '^$|#' /etc/nova/nova.conf.bak > /etc/nova/nova.conf

填充nova-api数据库

su -s /bin/sh -c "nova-manage api_db sync" nova
su -s /bin/sh -c "nova-manage cell_v2 map_cell0" nova
su -s /bin/sh -c "nova-manage cell_v2 create_cell --name=cell1 --verbose" nova
su -s /bin/sh -c "nova-manage db sync" nova

验证nova cell0和cell1是否正确注册

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

启动计算服务nova并将其配置为开机自启

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

检查nova服务是否启动

netstat -tnlup|egrep '8774|8775'
curl http://controller:8774
