# config.py

对配置进行管理。 定义了core\_opts的属性和默认值，包括绑定的主机地址、端口、配置文件默认位置、策略文件位置、VIF的起始Mac地址、DNS数量、子网的主机路由限制、DHCP释放时间、nova的配置信息等。

定义了core\_cli\_opts的属性和默认值，包括状态文件的路径。 注册上面定义的配置项。

主要包括 load\_paste\_app(app\_name)方法，从默认的paste config文件来读取配置，生成并返回WSGI应用。最关键的逻辑实现是

```
app = deploy.loadapp("config:%s" % config_path, name=app_name)
```

init(args)方法，读入配置文件，调用rpc的初始化函数，并检查base\_mac参数是否合法。 setup\_logging(conf)方法，配置logging模块，导入配置信息。

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://yeasy.gitbook.io/openstack_code_neutron/neutron/common/configpy.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
