OpenStack:安装Nova

>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

  1. 初始表:
    # nova-manage db sync

  2. 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

  1. 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)

  1. 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
    瞩目: 最终索要指定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:
