設定 metadata agent

1. 編輯 /etc/neutron/metadata_agent.ini，設定 [DEFAULT] 章節如下：

   [root@controller ~]# vim /etc/neutron/metadata_agent.ini 
   [root@controller ~]# egrep '^(\[DEF|[a-z])' /etc/neutron/metadata_agent.ini 
   [DEFAULT]
   nova_metadata_host = controller
   metadata_proxy_shared_secret = METADATA_SECRET
   

2. 編輯 /etc/nova/nova.conf，確認 [neutron] 章節有如下設定：

   [root@controller ~]# vim /etc/nova/nova.conf
   [root@controller ~]# egrep '^(\[neutron)' -A20 /etc/nova/nova.conf | grep -v ^#
   
   [neutron]
   url = http://controller:9696
   auth_url = http://controller:35357
   auth_type = password
   project_domain_name = default
   user_domain_name = default
   region_name = RegionOne
   project_name = service
   username = neutron
   password = 123qwe
   service_metadata_proxy = true
   metadata_proxy_shared_secret = METADATA_SECRET
