参考上一篇文章,这里做回顾以及整理:
使用vmware虚拟机(16.04)+dpdk(dpdk-19.08.2.tar)进行测试
1:定义两个网络适配器,第一个定义为桥接模式(用来连接dpdk)第二个设置为net模式,用来连接xshell方便测试
? 增加处理器,增加内存(方便设置多队列网卡,设置大内存页)
2:配置使多个网卡有效,
修改配置文件后要重启网络服务的,才能生效:sudo service networking restart
3:修改配置文件使环境支持多队列(虚拟机配置文件中修改对应网卡)
? 一定要在虚拟机关机状态下修改,修改后启动查看
? 启动后查看多队列网卡(这里网卡没有改为传统的eth命名,重启后网卡的命名会变化,由ens33变成的ens160):
? 重新修改一下,使多个网卡都生效:
修改后多网卡:(参考第二步,重新修改/etc/network/interfaces文件)
多队列网卡:
4:配置一下大内存页 /etc/default/gru,修改后一定要执行update-grub,并重启环境生效
? default_hugepages=1G hugepagesz=2M hugepages=1024 isolcpus=0-2
5:编译dpdk环境(./usertools/dpdk-setup.sh ),执行39(x86_64-native-linux-gcc),根据描述,生成特定环境的dpdk。
? 如果报错缺少numa.h 需要安装libnuma-dev
? 这里我用的39,生成64为的linux上的dpdk,生成一个x86_64-native-linux-gcc目录。
6:如果39执行成功,设置环境变量:
# export RTE_SDK=/home/hlp/dpdk/dpdk-stable-19.08.2
# export RTE_TARGET=x86_64-native-linux-gcc
7:编译dpdk环境(./usertools/dpdk-setup.sh ),执行43 插入 IGB_UIO 模块, 选择网卡为 vmxnet3 会加载此模块
8:编译dpdk环境(./usertools/dpdk-setup.sh ),执行44 插入 IGB_UIO 模块, 选择网卡为 e1000 会加载此模块
9:编译dpdk环境(./usertools/dpdk-setup.sh ),选择 49 绑定 igb_uio 模块。
? 会失败,关闭要绑定的网卡,重新进行绑定: 例如这里我关闭了ens160多队列网卡: sudo ifconfig ens160 down
会有对应的网卡提示,输入要绑定的网卡的前面的id就好,这里我已经绑定过:
一定要关闭网卡后,执行49的网卡绑定动作,可以重新执行49查看执行成功。
10:测试dpdk环境(./usertools/dpdk-setup.sh )执行53,运行testpmd
