环境

环境准备

  1. VmWare虚拟环境
  2. Host需求：2cpu，4G内存，3块网卡
  3. Ubuntu16.04

拓扑

搭建典型的c2s拓扑

  • 通过vsphere创建两个虚拟交换机
  • host1的第二个接口与vpp的第二个接口连在同一个交换机上
  • host2的第二个接口与vpp的第三个接口连在同一个交换机上

VPP安装先决条件

  1. Ubuntu安装git（git默认安装）
  2. Ubuntu安装dpdk，并绑定PCI的另外两个接口到dpdk

安装

官方文档提供了多种安装方式，并且推荐使用vagrant包，由于这里使用的是虚拟环境，则使用直接安装的方式

获取源码

1
$ git clone https://gerrit.fd.io/r/vpp

安装vpp

1
$ cd vpp
  • Step1

可以先执行一下make查看可以执行哪些操作

  • Step2 - make

$ make build-release

...

by executing "make install-dep"

Makefile:262: recipe for target '/root/vpp/build-root/.deps.ok' failed
make: *** [/root/vpp/build-root/.deps.ok] Error 1

如果遇到以上错误，则意味着缺少依赖包

1
$ make install-dep

依赖包安装完成后，再次执行make build-release

  • Step3 - Build deb包
1
$ make pkg-deb
  • Step4 - 安装VPP packages
1
$ dpkg -i /vpp/build-root/*.deb

中间可能会遇到vpp-api-python的错误，使用apt安装后重新安装packages

1
$ apt install vpp-api-python

配置

mkdir -p /etc/vpp
cp ./build-root/deb/debian/vpp/etc/vpp/startup.conf /etc/vpp/
cp ./build-root/deb/debian/vpp/etc/sysctl.d/80-vpp.conf /etc/sysctl.d/

虽然有警告信息，但似乎不影响使用

测试

根据startup.conf中的配置不同，选择不同的连接vpp方式
