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

修改nova的配置文件：

[[email protected] ~]# vim /etc/nova/nova.conf 
[placement]
auth_uri = http://10.10.10.11:5000
auth_url = http://10.10.10.11:35357/v3

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：

[[email protected] ~]# systemctl restart openstack-nova-compute.service

一.nova-rootwrap的作用 部署玩过openstack的都应该知道,它会生成一个nova用户来管理所有服务.nova身份在linux中属于普通用户级别,避免了一些需要root身份运行的操作,提高linux系统的安全性.但是openstack在实际过程中会调用很多外部命令,例如就network服务而言就有:`ip`,`ovs-vsctl`,`iptables`,`dnsmasq`,`brctl`等等,这些命令在linux中都是需要以root身份来运行的,如果是普通用户通常的做法是在命令前
