我们部署好OPenStack以及Swift后，想使用开放接口对Swift进行对接，但是却找不到入口，下面就一步一步介绍一下如何使用租户，用户名和密码对接Swift。

首先，我们安装好SWIFT后，在命令行执行

nova list和keystone tenant-list都会显示错误，如下图：

是因为，我们还没有导出。

进入OPenStack主页，点Access&Security，右上角有个Download Openstack RC File，点击下载。

下载到部署Openstack的主机上，点击打开。

里面有租户，用户名和密码的内容。修改之。改成以下：

#!/bin/bash

# To use an OpenStack cloud you need to authenticate against the Identity
# service named keystone,which returns a **Token** and **Service Catalog**.
# The catalog contains the endpoints for all services the user/tenant has
# access to - such as Compute,Image Service,Identity,Object Storage,Block
# Storage,and Networking (code-named nova,glance,keystone,swift,# cinder,and neutron).
#
# *NOTE*: Using the 2.0 *Identity API* does not necessarily mean any other
# OpenStack API is version 2.0. For example,your cloud provider may implement
# Image API v1.1,Block Storage API v2,and Compute API v2.0. OS_AUTH_URL is
# only for the Identity API served through keystone.
export OS_AUTH_URL=http://192.168.111.161:5000/v2.0

# With the addition of Keystone we have standardized on the term **tenant**
# as the entity that owns the resources.
export OS_TENANT_ID=b69864c4cb0a44cfb98d4281c9739081
export OS_TENANT_NAME="admin"

# In addition to the owning entity (tenant),openstack stores the entity
# performing the action as the **user**.
export OS_USERNAME="admin"
export OS_PASSWORD="swift"

[root@node-2 ~]# vi ~/openrc
[root@node-2 ~]# source ~/openrc 
[root@node-2 ~]# nova list

[root@node-2 ~]# keystone tenant-list
+----------------------------------+----------+---------+
|                id                |   name   | enabled |
+----------------------------------+----------+---------+
| 6d0dff68ecd24215bd971a8d1935ba03 |  admin   |   True  |
| d1f2d43d358743eda4e37bfd489c1163 | services |   True  |
+----------------------------------+----------+---------+
[root@node-2 ~]# 

成功返回token和URL

成功。
