1、故障现象：Ocata配置完nova服务后，发现computer节点居然没有起来：
[root@linux-node1 nova]# systemctl status openstack-nova-compute.service ● openstack-nova-compute.service - OpenStack Nova Compute Server Loaded: loaded (/usr/lib/systemd/system/openstack-nova-compute.service; enabled; vendor preset: disabled) Active: activating (start) since Fri 2017-03-10 08:53:58 CST; 6s ago Main PID: 14063 (nova-compute) CGroup: /system.slice/openstack-nova-compute.service └─14063 /usr/bin/python2 /usr/bin/nova-compute Mar 10 08:53:58 linux-node1.wanwan.com systemd[1]: Starting OpenStack Nova Compute Server...

2、处理过程
由于openstack ocata的版本发布时间还不太长，通过查资料发现这是一个bug，查看官方安装手册，没有对应解决方法
在控制节点上：
[root@linux-node1 ~]# yum -y install openstack-nova-placement-api
[root@linux-node1 ~]# openstack user create --domain default --password-prompt placement
User Password:#输入密码placement
Repeat User Password:#输入密码placement
[root@linux-node1 ~]# openstack role add --project service --user placement admin
[root@linux-node1 ~]# openstack service create --name placement --description "OpenStack Placement" placement
+-------------+----------------------------------+
| Field | Value |
+-------------+----------------------------------+

+---------------------+----------------------------------+
[root@linux-node1 ~]# openstack endpoint create --region RegionOne placement admin http://10.10.10.11:8778

[root@linux-node1 ~]# openstack endpoint create --region RegionOne placement internal http://10.10.10.11:8778
+--------------+----------------------------------+

+--------------+----------------------------------+
| enabled | True |

| service_name | placement |
| service_type | placement |
| url | http://10.10.10.11:8778 |
+--------------+----------------------------------+修改nova的配置文件：
[root@linux-node1 ~]# vim /etc/nova/nova.conf [placement] auth_uri = http://10.10.10.11:5000 auth_url = http://10.10.10.11:35357/v3 memcached_servers = 10.10.10.11:11211 auth_type = password project_domain_name = default user_domain_name = default project_name = service username = nova password = nova os_region_name = RegionOne
重启对应的服务：
[root@linux-node1 ~]# systemctl restart openstack-nova-compute.service [root@linux-node1 ~]# systemctl status openstack-nova-compute.service ● openstack-nova-compute.service - OpenStack Nova Compute Server Loaded: loaded (/usr/lib/systemd/system/openstack-nova-compute.service; enabled; vendor preset: disabled) Active: active (running) since Fri 2017-03-10 09:30:27 CST; 10s ago Main PID: 26692 (nova-compute) CGroup: /system.slice/openstack-nova-compute.service └─26692 /usr/bin/python2 /usr/bin/nova-compute Mar 10 09:30:06 linux-node1.wanwan.com systemd[1]: Starting OpenStack Nova Compute Server... Mar 10 09:30:27 linux-node1.wanwan.com systemd[1]: Started OpenStack Nova Compute Server.
查看openstack的计算服务清单：

小结：新版本的Openstack还是存在一些bug，只能先在测试环境中多进行测试，填坑的过程也是收货满满的
