DPDK系列之九：f-stack简介、安装和网络性能对比测试

**一、前言**

DPDK主要支持在TCP/IP层进行数据包的操作以满足SDN、NFV等应用场景，但是对于上层更复杂的TCP的操作和对应的七层应用的支持非常有限，所以F-stack进行了一些整合操作，将DPDK、FreeBSD用户态协议栈、Posix API、线程框架和一些应用(如Nginx和Redis)集成为一个可部署的端到端服务，并给出了其它七层应用移植的指导，从而使得复杂的七层应用也能享受DPDK的高速数据通道。

**二、编译和安装f-stack**

2.1 环境设置

OS：

CentOS-7-x86_64-Minimal-1611.iso

VM硬件：

VM1 run f-stack nginx
    VM2 run send request to nginx in VM1

1 CPU, 2GB memory and 2 NICs in host-only mode

    make
    make install
    
    cd /data/f-stack/tools
    make

**三、运行基于f-stack的nginx**

3.1 配置环境

准备配置文件

echo 1024 > /sys/kernel/mm/hugepages/hugepages-2048kB/nr_hugepages
    mkdir /mnt/huge
    mount -t hugetlbfs nodev /mnt/huge
    
    
    modprobe uio
    insmod /data/f-stack/dpdk/build/kmod/igb_uio.ko
    insmod /data/f-stack/dpdk/build/kmod/rte_kni.ko
    
    export myaddr=`ifconfig enp0s17 | grep "inet" | grep -v ":" | awk -F ' '  '{print $2}'`
    export mymask=`ifconfig enp0s17 | grep "netmask" | awk -F ' ' '{print $4}'`
    export mybc=`ifconfig enp0s17 | grep "broadcast" | awk -F ' ' '{print $6}'`
    export myhw=`ifconfig enp0s17 | grep "ether" | awk -F ' ' '{print $2}'`
    export mygw=`route -n | grep 0.0.0.0 | grep enp0s17 | grep UG | awk -F ' ' '{print $2}'`
    
    export FF_PATH=/data/f-stack
    export FF_DPDK=/data/f-stack/dpdk/build
    
    ifconfig enp0s17 down
    python /data/f-stack/dpdk/tools/dpdk-devbind.py --bind=igb_uio enp0s17
    python /data/f-stack/dpdk/tools/dpdk-devbind.py  --status

3.2 运行DPDK和Nginx

cat /data/f-stack/config.ini
    [dpdk]
    ## Hexadecimal bitmask of cores to run on.
    lcore_mask=1
    channel=4
    promiscuous=1
    numa_on=1
    ## TCP segment offload, default: disabled.
    tso=0
    ## HW vlan strip, default: enabled.
    vlan_strip=1
    
    # enabled port list
    #
    # EBNF grammar:
    #
    #    exp      ::= num_list {"," num_list}
    #    num_list ::= <num> | <range>
    #    range    ::= <num>"-"<num>
    #    num      ::= '0' | '1' | '2' | '3' | '4' | '5' | '6' | '7' | '8' | '9'
    #
    # examples
    #    0-3       ports 0, 1,2,3 are enabled
    #    1-3,4,7   ports 1,2,3,4,7 are enabled
    port_list=0
    
    ## Port config section
    ## Correspond to dpdk.port_list's index: port0, port1...
    [port0]
    addr=10.0.2.15
    netmask=255.255.255.0
    broadcast=10.0.2.255
    gateway=10.0.2.2
    ... ...

3.2 运行nginx

cp /data/f-stack/config.ini /usr/local/nginx_fstack/
    cp /data/f-stack/config.ini /usr/local/nginx_fstack/conf/f-stack.conf
    
    /usr/local/nginx_fstack/sbin/nginx

VM1:

[root@fstack-dev1 ~]# ps -ef | grep nginx
    root     17511     1  0 00:02 ?        00:00:00 nginx: master process /usr/local/nginx_fstack/sbin/nginx

    EAL: WARNING: Address Space Layout Randomization (ASLR) is enabled in the kernel.
    EAL:    This may cause issues with mapping memory into secondary processes

    ether 8:0:27:ed:fd:92
    inet 192.168.56.101 netmask 0xffffff00 broadcast 192.168.56.255

VM2:

[root@fstack-dev2 wrk-master]# arp -an
    ? (192.168.56.101) at 08:00:27:ed:fd:92 [ether] on enp0s10
    ? (192.168.56.100) at 08:00:27:65:b2:2a [ether] on enp0s10

    ? (72.163.255.11) at 6c:41:6a:ff:1f:7f [ether] on enp0s9

从VM2访问VM1基于f-stack的nginx：

[root@fstack-dev2 wrk-master]# curl http://192.168.56.101/
    <!DOCTYPE html>
    <html>
    <head>

        }
    </style>
    </head>

**五、性能测试**

5.1 在VM2安装wrk

git clone https://github.com/wg/wrk.git wrk
    cd wrk
    make

5.2 在VM1启动正常的Nginx并测试

在VM2运行wrk结果如下：

[root@fstack-dev2 wrk-master]# ./wrk -t10 -c 1k -d30s http://192.168.56.101/index.html
    Running 30s test @ http://192.168.56.101/index.html

    Requests/sec:  14380.66
    Transfer/sec:     11.66MB

5.3 在VM1启动基于f-stack的Nginx并测试

start.sh 
    echo 1024 > /sys/kernel/mm/hugepages/hugepages-2048kB/nr_hugepages
    mkdir /mnt/huge
    mount -t hugetlbfs nodev /mnt/huge
    modprobe uio
    insmod /data/f-stack/dpdk/build/kmod/igb_uio.ko
    insmod /data/f-stack/dpdk/build/kmod/rte_kni.ko
    ifconfig enp0s17 down
    python /data/f-stack/dpdk/tools/dpdk-devbind.py --bind=igb_uio enp0s17
    python /data/f-stack/dpdk/tools/dpdk-devbind.py  --status
    /usr/local/nginx_fstack/sbin/nginx
    sleep 3
    ps -ef| grep nginx

在VM2运行wrk结果如下：

[root@fstack-dev2 wrk-master]# ./wrk -t10 -c 1k -d30s http://192.168.56.101/index.html
    Running 30s test @ http://192.168.56.101/index.html
