linux环境下安装dpdk,DPDK环境搭建及Helloworld样例

配置虚拟机环境

多张网卡，一张网卡是无法运行DPDK的，至少要两张。

多核CPU，可以在实现多个DPDK逻辑调度核lcore。

安装DPDK

1.在DPDK官网下载DPDK的压缩包：http://core.dpdk.org/download, 我下载的是稳定版本18.05.1. 2.进入root权限，解压下载的安装包到用户目录下。

tar xJf ddpdk-stable-18.05.1.tar.xz

cd dpdk-stable-18.05.1/

3.配置环境变量

make config T=x86_64-native-linuxapp-gcc

sed -ri 's,(PMD_PCAP=).*,\1y,' build/.config

4.安装

make

运行DPDK

1.设置环境变量

export RTE_SDK=/home/liuhy/dpdk-stable-18.05.1/

export RTE_TARGET=build

2.编译example程序

make -C examples

3.配置大页表

mkdir -p /mnt/huge

mount -t hugetlbfs nodev /mnt/huge

echo 64 > /sys/devices/system/node/node0/hugepages/hugepages-2048kB/nr_hugepages

4.运行helloworld，效果如下：

root@liuhy-VirtualBox:/home/liuhy/dpdk-stable-18.05.1/examples/helloworld/build# ./helloworld -c f
