安装软件包
[root@controller ~]# yum install openstack-nova-api openstack-nova-conductor openstack-nova-console openstack-nova-novncproxy openstack-nova-scheduler openstack-nova-placement-api -y
编辑nova主配置文件
[root@controller ~]# vim /etc/nova/nova.conf[DEFAULT]enabled_apis = osapi_compute,metadatatransport_url = rabbit://openstack:openstack@controllermy_ip = 192.168.223.11use_neutron = Truefirewall_driver = nova.virt.firewall.NoopFirewallDriver[api_database] connection = mysql+pymysql://nova:nova@controller/nova_api[database] connection = mysql+pymysql://nova:nova@controller/nova[api]auth_strategy = keystone[keystone_authtoken]auth_uri = http://controller:5000auth_url = http://controller:35357memcached_servers = controller:11211auth_type = passwordproject_domain_name = defaultuser_domain_name = defaultproject_name = serviceusername = novapassword = nova[vnc]enabled = trueserver_listen = $my_ipserver_proxyclient_address = $my_ip[glance]api_servers = http://controller:9292[oslo_concurrency]lock_path = /var/lib/nova/tmp[placement]os_region_name = RegionOneproject_domain_name = Defaultproject_name = serviceauth_type = passworduser_domain_name = Defaultauth_url = http://controller:35357/v3username = placementpassword = placement
由于软件包的一个bug，需要在/etc/httpd/conf.d/00-nova-placement-api.conf文件中添加如下配置
[root@controller ~]# vim /etc/httpd/conf.d/00-nova-placement-api.conf[root@controller ~]# systemctl restart httpd ##重启服务 = 2.4> Require all granted < 2.4> Order allow,deny Allow from all
同步数据库
[root@controller ~]# su -s /bin/sh -c "nova-manage api_db sync" nova
注册cell0数据库
[root@controller ~]# su -s /bin/sh -c "nova-manage cell_v2 map_cell0" nova
创建cell1 cell
[root@controller ~]# su -s /bin/sh -c "nova-manage cell_v2 create_cell --name=cell1 --verbose" nova
同步nova数据库
[root@controller ~]# su -s /bin/sh -c "nova-manage db sync" nova
验证 nova、 cell0、 cell1数据库是否注册正确
[root@controller ~]# nova-manage cell_v2 list_cells+-------+--------------------------------------+------------------------------------+-------------------------------------------------+| 名称 | UUID | Transport URL | 数据库连接 |+-------+--------------------------------------+------------------------------------+-------------------------------------------------+| cell0 | 00000000-0000-0000-0000-000000000000 | none:/ | mysql+pymysql://nova:****@controller/nova_cell0 || cell1 | ac6fcd37-7a3e-44ad-a823-5fa5289ac826 | rabbit://openstack:****@controller | mysql+pymysql://nova:****@controller/nova |+-------+--------------------------------------+------------------------------------+-------------------------------------------------+
设置开机自启和启动
[root@controller ~]# systemctl enable openstack-nova-api.service \> openstack-nova-consoleauth.service openstack-nova-scheduler.service \> openstack-nova-conductor.service openstack-nova-novncproxy.serviceCreated symlink from /etc/systemd/system/multi-user.target.wants/openstack-nova-api.service to /usr/lib/systemd/system/openstack-nova-api.service.Created symlink from /etc/systemd/system/multi-user.target.wants/openstack-nova-consoleauth.service to /usr/lib/systemd/system/openstack-nova-consoleauth.service.Created symlink from /etc/systemd/system/multi-user.target.wants/openstack-nova-scheduler.service to /usr/lib/systemd/system/openstack-nova-scheduler.service.Created symlink from /etc/systemd/system/multi-user.target.wants/openstack-nova-conductor.service to /usr/lib/systemd/system/openstack-nova-conductor.service.Created symlink from /etc/systemd/system/multi-user.target.wants/openstack-nova-novncproxy.service to /usr/lib/systemd/system/openstack-nova-novncproxy.service.[root@controller ~]# systemctl start openstack-nova-api.service \> openstack-nova-consoleauth.service openstack-nova-scheduler.service \> openstack-nova-conductor.service openstack-nova-novncproxy.service
[root@compute1 ~]# yum install openstack-nova-compute -y
安装完成配置文件
[root@compute1 ~]# vim /etc/nova/nova.conf[DEFAULT] [root@compute1 ~]# vim /etc/nova/nova.conf enabled_apis = osapi_compute,metadatatransport_url = rabbit://openstack:openstack@controllermy_ip = 192.168.223.12use_neutron = Truefirewall_driver = nova.virt.firewall.NoopFirewallDriver[api]auth_strategy = keystone[keystone_authtoken]auth_uri = http://controller:5000auth_url = http://controller:35357memcached_servers = controller:11211auth_type = passwordproject_domain_name = defaultuser_domain_name = defaultproject_name = serviceusername = novapassword = nova[vnc]enabled = Trueserver_listen = 0.0.0.0server_proxyclient_address = $my_ipnovncproxy_base_url = http://controller:6080/vnc_auto.html[glance]api_servers = http://controller:9292[oslo_concurrency]lock_path = /var/lib/nova/tmp[placement]os_region_name = RegionOneproject_domain_name = Defaultproject_name = serviceauth_type = passworduser_domain_name = Defaultauth_url = http://controller:35357/v3username = placementpassword = placement
配置完成还应该查看机器是否支持硬件加速
[root@compute1 ~]# egrep -c '(vmx|svm)' /proc/cpuinfo2 ##这个值大于1[root@compute1 ~]# lsmod | grep kvm ##可以过滤出信息说明可以kvm_intel 188688 0 kvm 636921 1 kvm_intelirqbypass 13503 1 kvm
下来就可以开启服务
[root@compute1 ~]# systemctl enable libvirtd.service openstack-nova-compute.service[root@compute1 ~]# systemctl start libvirtd.service openstack-nova-compute.service
将计算节点加入后可以在控制节点列出查看
