Ocata:Packstack Ocata does not configure nova for placement API

1、故障现象：Ocata配置完nova服务后，发现computer节点居然没有起来：

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

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 ~]

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
