4.1.2安装配置组件
1. 安装软件包
[[email protected]_168_200_101 ~]# yum install -y openstack-nova-api openstack-nova-conductor \ openstack-nova-console openstack-nova-novncproxy openstack-nova-scheduler \ openstack-nova-placement-api openstack-nova-compute
2. 编辑/etc/nova/nova.conf 文件并完成下列操作:
A. 在[DEFAULT]小节，只启用 compute 和 metadata 的 API。
[DEFAULT] #.... enabled_apis = osapi_compute,metadata
B. 在[api_database]和[database]小节，配置数据库访问：
[api_database] #.... connection = mysql+pymysql://nova:[email protected]/nova_api
[database] #.... connection = mysql+pymysql://nova:[email protected]/nova
C. 在[DEFAULT]小节配置 RabbitMQ 消息队列访问：
[DEFAULT] #.... transport_url = rabbit://openstack:[email protected]
D. 在[api]和[keystone_authtoken]小节配置身份服务访问信息：
[api] #.... auth_strategy = keystone
[keystone_authtoken] #.... auth_uri = http://controller:5000 auth_url = http://controller:35357 memcached_servers = controller:11211 auth_type = password project_domain_name = default user_domain_name = default project_name = service username = nova password = lookback
E. 在[DEFAULT]小节，配置 my_ip 配置项为管理节点的管理接口 IP地址。
[DEFAULT] #.... my_ip = 192.168.200.101
F. 在[DEFAULT]小节，启用支持 neutron 网络服务：
[DEFAULT] #.... use_neutron = True firewall_driver = nova.virt.firewall.NoopFirewallDriver
G. 在[vnc]小节，配置 vnc 代理，使用管理节点的管理接口 IP 地址：
[vnc] #.... enabled = true vncserver_listen = $my_ip vncserver_proxyclient_address = $my_ip
H. 在[glance]小节，配置镜像服务 API 的位置：
[glance] #.... api_servers = http://controller:9292
I. 在[oslo_concurrency]小节，配置锁路径：
[oslo_concurrency] #.... lock_path = /var/lib/nova/tmp
J. 在[placement]小节,配置 placement API 信息：
[placement] #.... os_region_name = RegionOne project_domain_name = Default project_name = service auth_type = password user_domain_name = Default auth_url = http://controller:35357/v3 username = placement password = lookback
[[email protected]_168_200_101 ~]# grep -Ev '^(#|$)' /etc/nova/nova.conf [DEFAULT] enabled_apis = osapi_compute,metadata transport_url = rabbit://openstack:[email protected] my_ip = 192.168.200.101 use_neutron = True firewall_driver = nova.virt.firewall.NoopFirewallDriver [api] auth_strategy = keystone [api_database] connection = mysql+pymysql://nova:[email protected]/nova_api [barbican] [cache] [cells] [cinder] [compute] [conductor] [console] [consoleauth] [cors] [crypto] [database] connection = mysql+pymysql://nova:[email protected]/nova [ephemeral_storage_encryption] [filter_scheduler] [glance] api_servers = http://controller:9292 [guestfs] [healthcheck] [hyperv] [ironic] [key_manager] [keystone] [keystone_authtoken] auth_uri = http://controller:5000 auth_url = http://controller:35357 memcached_servers = controller:11211 auth_type = password project_domain_name = default user_domain_name = default project_name = service username = nova password = lookback [libvirt] [matchmaker_redis] [metrics] [mks] [neutron] [notifications] [osapi_v21] [oslo_concurrency] lock_path = /var/lib/nova/tmp [oslo_messaging_amqp] [oslo_messaging_kafka] [oslo_messaging_notifications] [oslo_messaging_rabbit] [oslo_messaging_zmq] [oslo_middleware] [oslo_policy] [pci] [placement] os_region_name = RegionOne project_domain_name = Default project_name = service auth_type = password user_domain_name = Default auth_url = http://controller:35357/v3 username = placement password = lookback [quota] [rdp] [remote_debug] [scheduler] [serial_console] [service_user] [spice] [trusted_computing] [upgrade_levels] [vendordata_dynamic_auth] [vmware] [vnc] enabled = true vncserver_listen = $my_ip vncserver_proxyclient_address = $my_ip [workarounds] [wsgi] [xenserver] [xvp] [[email protected]_168_200_101 ~]#
K. 由于软件包 bug，必须将下列配置添加到文件/etc/httpd/conf.d/00-nova-placement-api.conf 中，以启用对 Placement API的访问。
<Directory /usr/bin>
<IfVersion >= 2.4>
Require all granted
</IfVersion>
<IfVersion < 2.4>
Order allow,deny
Allow from all
</IfVersion>
</Directory>

1. 探测你的计算节点是否支持硬件虚拟机化：
[[email protected]_168_200_101 ~]# egrep -c '(vmx|svm)' /proc/cpuinfo 0 [[email protected]_168_200_101 ~]#
如果结果大于或等于 1，则表示你的计算节点支持硬件虚拟化。如果等于 0，则表示不支持，那么你必须配置 libvirt，用 QEMU 代替KVM。
编辑/etc/nova/nova.conf 文件中的[libvirt]小节：
[libvirt] # ... virt_type = qemu
2. 启动计算服务并设置开机自动运行：
