创建服务实体和API端点 in Installation Guide

[Mingxuan Li]

创建认证服务的API端点时，文档有三个错误：
$ openstack endpoint create --region RegionOne identity public http://controller:5000/v3
$ openstack endpoint create --region RegionOne identity internal http://controller:5000/v3
$ openstack endpoint create --region RegionOne identity admin http://controller:5000/v3
针对上述的执行命令，系统会提示错误。
应该修改为如下：
$ openstack endpoint create --region RegionOne keystone public http://controller:5000/v3
$ openstack endpoint create --region RegionOne keystone internal http://controller:5000/v3
$ openstack endpoint create --region RegionOne keystone admin http://controller:5000/v3

请按照文档顺序操作. 你应该漏了这步:
openstack service create \
  --name keystone --description "OpenStack Identity" identity

@amotoki this is not a bug, just a mistake.
command 'openstack endpoint' support service name or service type as parameter.
now 'keystone' works fine but 'identity' not, so I guess that he must miss a step mentioned above.
