关于opentack的(2)--利用debug信息大概了解api的调用过程

进入openshit文件夹,执行(如果是通过openshit部署的)

root@os:~/openshit# source admin-env.sh

然后再执行查看虚拟机实例:

root@os:~/openshit# nova list
+--------------------------------------+------+--------+------------+-------------+----------+
| ID                                   | Name | Status | Task State | Power State | Networks |
+--------------------------------------+------+--------+------------+-------------+----------+
| 2342b4c2-236c-4d49-9707-af77529f490b | test | ACTIVE | -          | Running     |          |
+--------------------------------------+------+--------+------------+-------------+----------+

加调试选项debug看到更多信息:

可以看到有两个调用过程:

1.http://192.168.16.190:35357/v2.0/tokens

这是访问keystone,获取token以及其他信息(这里是租户id等),需要附带管理用户名和密码

2.http://192.168.16.190:8774/v2/6ff51bde9ba940e8b90892988a0c3a82/servers/detail

这是访问nova,获取租户的虚拟机实例,需要附带第一步获取的token
