VPP（Vector Packet Processing）配置工具
前言
- VPP提供了一个配置工具，让用户可以简单快捷地配置VPP。用户可以通过一些简单的命令配置VPP，功能包括安装及一些基本配置和测试用例。
使用
- 先安装一个python的pip模块，使用pip安装VPP的配置工具。
- 如果不确定要如何配置，可以选择默认值：y ，而对于数字，如果问题中有形如[1024]的样子，则1024就是默认值。
在Ubuntu系统下安装运行
- 安装pyhton的pip
$ sudo -H bash
# apt-get install python-pip
Reading package lists... Done
Building dependency tree
Reading state information... Done
python-pip is already the newest version (8.1.1-2ubuntu0.4).
- 安装VPP-config
# pip install vpp-config

# vpp-config
Welcome to the VPP system configuration utility
These are the files we will modify:
/etc/vpp/startup.conf
/etc/sysctl.d/80-vpp.conf
/etc/default/grub
Before we change them, we'll create working copies in /usr/local/vpp/vpp-config/dryrun
Please inspect them carefully before applying the actual configuration (option 3)!
What would you like to do?
1) Show basic system information
2) Dry Run (Will save the configuration files in /usr/local/vpp/vpp-config/dryrun for inspection)
and user input in /usr/local/vpp/vpp-config/configs/auto-config.yaml
3) Full configuration (WARNING: This will change the system configuration)
4) List/Install/Uninstall VPP.
5) Execute some basic tests.

对于Developers
修改代码很简单。编辑并调试根目录中的代码。为了做到这一点，我们需要一个脚本，将文件复制或数据到适当的地方。这是他们最终与点安装。对于Ubuntu，这是/ usr / local / vpp / vpp-config。对于Centos / usr / vpp / vpp-config。我提供了一个能够正确复制相关文件的脚本（./scripts/cp-data.sh）。我还提供了一个清理环境的脚本。这使开发人员可以从头开始。这些是在此环境中运行实用程序的步骤。这些脚本旨在从根目录运行。
./scripts/clean.sh
./scripts/cp-data.sh
./vpp_config.py
当该实用程序使用pip安装时，wrapper scripts / vpp-config被写入/ usr / local / bin。但是，在本地调试此脚本的起点是./vpp_config.py。通过从根目录执行./vpp_config.py来运行该实用程序。
代码中的起点位于vpp_config.py中。大部分工作都在./vpplib中的文件中完成
上传到Pypi

测试用例
设置IP地址
- vpp配置好后我们可以把ip地址加入到这些已经配置好的接口上。一旦完成，你可以试着ping一下，然后一个运行脚本会创建： /usr/local/vpp/vpp-config/scripts/set_int_ipv4_and_up for Ubuntu and /usr/vpp/vpp-config/scripts/set_int_ipv4_and_up for Centos。
用这个脚本以后可以用来配置IP地址。
