git clone 下来

进入 vpp目录  
依次执行命令

make install-dep
    make bootstrap
    make build

设置大页

mkdir /mnt/huge 
    mount -t hugetlbfs nodev /mnt/huge
    echo 1024 > /sys/kernel/mm/hugepages/hugepages-2048kB/nr_hugepages
    cat /proc/meminfo| grep Huge

之后就可以直接 make run 执行了。  
![这里写图片描述][SouthEast]  
**使用 quit命令退出**  
但是之后要指定配置文件执行就要编译 dpdk了。  
！！！在dpdk的目录下的 Makefile文件中改下配置 将 RTE\_EAL\_IGB\_UIO 设置为y

才会有 igb\_uio.ko 文件

之后加载驱动

modprobe uio
    insmod igb_uio.ko

dmesg

查看 成功没有

绑定网卡，配置文件等，具体可以参考最上面的链接，本人也是指定配置文件会出错，暂时还没搞懂

但我的目的是执行测试框架：  
要执行测试框架只要 make run 可以起来就可以了

在VPP目录下执行

make test

构建执行测试用例

![这里写图片描述][SouthEast 1]

就是这样的

执行 命令

make

最重要的如何执行单个测试用例：

make test-shell
    python test_*.py（要执行的单个测试用例）

(virtualenv) root@ubuntu:~/vpp/vpp/test#
    (virtualenv) root@ubuntu:~/vpp/vpp/test# python test_ip4.py
    Running tests using custom test runner
    Active filters: file=None, class=None, function=None
    10 out of 10 tests match specified filters
    Not running extended tests (some tests will be skipped)

所有分析要看 Makefile文件

其实执行测试的是这条

@bash -c "source $(PYTHON_VENV_PATH)/bin/activate && python run_tests.py -d $(TEST_DIR) $(UNITTEST_EXTRA_OPTS)"

构建了python的虚拟环境，然后执行 run\_test 指定目录也就是 test目录。  
期间遇到了很多很多的问题，比如里面的变量很多都是系统变量。开始自己设置各种问题。使用 make retest和 make test-shell可以不用设置。 对Makefile文件也不熟悉，要学习的还很多啊。  
之后会具体分析测试框架
