注意：meson安装依赖Python3,如果安装失败需要先安装Python3，然后再安装meson

yum -y install python3

3. DPDK 编译安装

• 解压

tar xf dpdk.tar.gz
cd dpdk

• 构建

meson -Dexamples=all build
ninja-build -C build

• 内存设置

  mkdir -p /dev/hugepages
  mountpoint -q /dev/hugepages || mount -t hugetlbfs nodev /dev/hugepages
  echo 64 > /sys/devices/system/node/node0/hugepages/hugepages-2048kB/nr_hugepages

4. 测试

将eth0网口 和 eth1网口 用同一根网线连接起来

  build/app/dpdk-testpmd -c7 --vdev=net_pcap0,iface=eth0 --vdev=net_pcap1,iface=eth1 --
                  -i --nb-cores=2 --nb-ports=2 --total-num-mbufs=2048

  testpmd> show port stats all
