Question

如何开始使用OpenStack命令行和API

Answer 1

打开下载的文件(这里举个例子，我以admin用户登录的)，对内容稍作修改(主要是最后那个password，改成你登录horizon的密码，其他内容不要改)：
#!/bin/bash

# With the addition of Keystone, to use an openstack cloud you should
# authenticate against keystone, which returns a **Token** and **Service
# Catalog**. The catalog contains the endpoint for all services the
# user/tenant has access to - including nova, glance, keystone, swift.
#
# *NOTE*: Using the 2.0 *auth api* does not mean that compute api is 2.0. We
# will use the 1.1 *compute api*
export OS_AUTH_URL=http://119.81.159.110:5000/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=6d0dff68ecd24215bd971a8d1935ba03
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="tUWkuBpN"

好了，现在你可以登录后台，新建一个文件，然后把上面的内容复制进去，执行久违的source，然后再次运行命令：
[root@node-2 ~]# vi ~/openrc
[root@node-2 ~]# source ~/openrc
[root@node-2 ~]# www.hnnedu.com nova list

[root@node-2 ~]# keystone tenant-list
