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。

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

3.3 查看状态

进程

四、互联访问

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
root     17513 17511 91 00:02 ?        00:00:11 nginx: worker process
root     17535  2163  0 00:02 pts/0    00:00:00 grep --color=auto nginx

/data/f-stack/tools/ifconfig/ifconfig
EAL: WARNING: Address Space Layout Randomization (ASLR) is enabled in the kernel.
EAL:    This may cause issues with mapping memory into secondary processes
lo0: flags=8008<LOOPBACK,MULTICAST> metric 0 mtu 16384
options=600003<RXCSUM,TXCSUM,RXCSUM_IPV6,TXCSUM_IPV6>
groups: lo 
f-stack-0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
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
? (192.168.56.1) at 0a:00:27:00:00:00 [ether] on enp0s10
? (72.163.255.1) at 00:08:e3:ff:fd:98 [ether] on enp0s9
? (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>

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

    Req/Sec     1.49k     0.92k    7.89k    74.29%

  Socket errors: connect 0, read 299, write 0, timeout 413
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
