>安装Nova
1. 安装
# apt-get install nova-novncproxy novnc nova-api
nova-ajax-console-proxy nova-cert nova-conductor
nova-consoleauth nova-doc nova-scheduler
python-novaclient
删除sqlite文件
rm -f /var/lib/nova/nova.sqlite
2. 创建db
create database nova;
grant all privileges on nova.* to 'nova'@'%' identified by 'openstack';
grant all privileges on nova.* to 'nova'@'localhost' identified by 'openstack';
3. 创建user, role
# keystone user-create --name=nova --pass=openstack
# keystone user-role-add --user=nova --tenant=service --role=admin
4. 配置:
(1)配置/etc/nova/nova.conf :
[DEFAULT]
auth_strategy=keystone
rpc_backend = nova.rpc.impl_kombu
rabbit_host = controller
rabbit_password = openstack
my_ip=192.168.2.3
[database]
connection = mysql://nova:openstack@controller/nova
[keystone_authtoken]
auth_uri = http://controller:35357
auth_host = controller
auth_port = 35357
auth_protocol = http
admin_tenant_name = service
admin_user = nova
admin_password = openstack
(2)配置/etc/nova/api-paste.ini:
[filter:authtoken]
paste.filter_factory = keystoneclient.middleware.auth_token:filter_factory
auth_uri = http://controller:35357/v2.0
auth_host = controller
auth_port = 35357
auth_protocol = http
admin_tenant_name = service
admin_user = nova
admin_password = openstack
5. 初始表:
# nova-manage db sync
6. 注册service, endpoint:
# keystone service-create
--name=nova --type=compute
--description="Nova Compute service"
# keystone endpoint-create
--service-id=0c88f9f2a63142a7a01656e22f86b1d5
--publicurl=http://controller:8774/v2/%(tenant_id)s
--internalurl=http://controller:8774/v2/%(tenant_id)s
--adminurl=http://controller:8774/v2/%(tenant_id)s
6. 重启nova服务.
service nova-api restart
service nova-cert restart
service nova-consoleauth restart
service nova-scheduler restart
service nova-conductor restart
service nova-novncproxy restart
---------------------------------------------------
遗漏compute node部分:
1.安装
apt-get install nova-compute-qemu python-guestfs
#据说是kernel的某个BUG
dpkg-statoverride --update --add root root 0644 /boot/vmlinuz-$(uname -r)
2. 配置:
(1)配置/etc/nova/nova.conf
[DEFAULT]
...
auth_strategy=keystone
my_ip=192.168.0.11
vnc_enabled=True
vncserver_listen=0.0.0.0
vncserver_proxyclient_address=192.168.0.11
novncproxy_base_url=http://controller:6080/vnc_auto.html
glance_host=controller
注意: 最后需要指定glance_host.
[database]
# The SQLAlchemy connection string used to connect to the database
connection = mysql://nova:NOVA_DBPASS@controller/nova
(2)配置/etc/nova/api-paste.ini
[filter:authtoken]
paste.filter_factory = keystoneclient.middleware.auth_token:filter_factory
auth_host = controller
auth_port = 35357
auth_protocol = http
admin_tenant_name = service
admin_user = nova
admin_password = openstack
最后的nova.conf, 包含nova-->keystone, nova-->glance, nova-->neutron的参数:
