基于DPDK抓包的Suricata安装部署


一、背景

Suricata支持网卡在线抓包和离线读取PCAP包两种形式的抓包:

  • 离线抓包天然具有速度慢、非实时的特点
  • 在线捕获数据包又包括常规网卡抓包、PF_RING和DPDK的方式

由于项目分光的流量较大, 软件自带的抓包方式并不能满足需求,因此采用了基于DPDK的Suricata在线捕获网卡数据包的方式。

 

二、 服务器配置与对应软件版本

操作系统:Centos7.6 1810
内核版本:3.10.0-1160.88.1.el7.x86_64
网卡信息:Intel X722 万兆光口以太网卡
DPDK版本:dpdk-19.11.14
Suricata版本:DPDK_Suricata-4.1.4

 

三、部署安装DPDK

基于DPDK抓包的Suricata版本只更新到4.1.4,因此对DPDK版本有要求,经过测试推荐使用 DPDK-19.11.14

DPDK官网下载地址:http://fast.dpdk.org/rel/dpdk-19.11.14.tar.gz

1、安装dpdk-19.11.14需要操作系统内核版本大于3.2,如果版本过低,可以通过以下方式升级

1 [root@ids-dpdk ~]# cat /etc/redhat-release
2 CentOS Linux release 7.6.1810 (Core)
3 [root@ids-dpdk ~]# uname -r #查看一下系统版本
4 3.10.0-957.el7.x86_64
5 [root@ids-dpdk ~]# rpm -qa kernel #通过rpm命令查看我所安装的内核版本
6 kernel-3.10.0-957.el7.x86_64
7 [root@ids-dpdk ~]# ls /usr/src/kernels/ #查看有没有相应的内核开发包
8 空 #如果该目录下没有系统内核源码,执行以下操作
9 [root@ids-dpdk ~]# yum install kernel-devel #安装内核头文件后
10 [root@ids-dpdk ~]# ls /usr/src/kernels/
11 3.10.0-1160.88.1.el7.x86_64
12 #两个版本号不一致,进行升级并重启
13 [root@ids-dpdk ~]# yum -y update kernel kernel-devel
14 [root@ids-dpdk ~]# reboot
15 #再此查看,版本号一致,问题解决
16 [root@ids-dpdk ~]# ls /usr/src/kernels/
17 3.10.0-1160.88.1.el7.x86_64
18 [root@ids-dpdk ~]# uname -r
19 3.10.0-1160.88.1.el7.x86_64

 

2、安装依赖包

sudo yum install -y gcc make
sudo yum install -y libpcap libpcap-devel
sudo yum install -y numactl numactl-devel
sudo yum install -y pciutils

 

3、从dpdk官网下载dpdk压缩包并解压

将dpdk压缩包下载到/home目录下并解压
wget http://fast.dpdk.org/rel/dpdk-19.11.14.tar.gz
tar -zxvf dpdk-19.11.14.tar.gz

 

4、DPDK编译和网卡绑定

1. 设置环境变量,命令行执行:
[root@ids-dpdk ~]# export RTE_SDK='/home/dpdk-19.11.14'
[root@ids-dpdk ~]# export RTE_TARGET=x86_64-native-linuxapp-gcc
#(对于64位机用这个命令,对于32位机用i686-native-linuxapp-gcc)

2. 查看环境变量是否设置好:
[root@ids-dpdk ~]# env |grep RTE
RTE_SDK=/home/dpdk-stable-19.11.14
RTE_TARGET=x86_64-native-linuxapp-gcc

3. 关闭要绑定的网卡,否则绑定dpdk时不成功
ifconfig  ens1f0 down

4. 进入到dpdk-19.11.14/usertools目录下
cd /home/dpdk-19.11.14/usertools
执行./dpdk-setup.sh

会输出一列可选操作:

5、DPDK_Suricata编译与安装

1、安装依赖
[root@ids-dpdk ~]# yum -y install gcc libpcap-devel pcre-devel libyaml-devel file-devel \
  zlib-devel jansson-devel nss-devel libcap-ng-devel libnet-devel tar make openssl openssl-devel \
  libnetfilter_queue-devel lua-devel PyYAML libmaxminddb-devel rustc cargo librdkafka-devel \
  lz4-devel libxml2 autoconf

2、下载DPDK_Suricata安装包
##目前DPDK_Suricata项目作者已经到4.1.4,只是目录仍沿用4.1.1,直接克隆项目代码即可
[root@ids-dpdk ~]# git clone https://github.com/vipinpv85/DPDK_SURICATA-4_1_1

3、编译并安装DPDK_Suricata
进入DPDK_Suricata目录下:
[root@ids-dpdk ~]# cd /home/DPDK_SURICATA-4_1_1/suricata-4.1.4
构建支持DPDK的配置脚本:
[root@ids-dpdk suricata-4.1.4]# autoconf
使用dpdk进行配置:
[root@ids-dpdk suricata-4.1.4]# ./configure --prefix=/usr --sysconfdir=/etc --localstatedir=/var --enable-dpdk  
编译DPDK_Suricata:
[root@ids-dpdk suricata-4.1.4]# make
安装DPDK_Suricata:
[root@ids-dpdk suricata-4.1.4]# make install
更新规则文件:
[root@ids-dpdk suricata-4.1.4]# make install-full
安装相关配置文件:
[root@ids-dpdk suricata-4.1.4]# make install-conf

 

 6、测试运行抓包

修改配置文件suricata.yaml

[root@ids-dpdk ~]# vim /etc/suricata/suricata.yaml
搜索 DPDK关键词,修改input-output-map和interface两处参数值
将input-output-map修改成:input-output-map: ["0"]
将interface修改成:- interface: 0
修改完成后执行 :wq 保存并退出

 

 

测试运行:

[root@ids-dpdk ~]# suricata
如果报以下错误,是库文件未找到的原因
/usr/bin/suricata: error while loading shared libraries: libhtp.so.2: cannot open shared object file: No such file or directory
执行命令手动建立到libhtp.so.2的软链接
[root@ids-dpdk ~]# ln -s /usr/lib/libhtp.so.2 /lib64/libhtp.so.2
然后执行命令开始运行dpdk抓包测试
[root@ids-dpdk ~]# suricata --dpdk

至此,DPDK_Suricata开启DPDK抓包

 

7、DPDK脚本补充

由于服务器开关机会导致DPDK绑定的网卡会被默认解绑,为简化重新机械的绑定工作,通过shell脚本实现自动化DPDK绑定网卡。

编辑/etc/profile,设置环境变量

在done和unset i之间添加环境变量,执行:wq保存并退出,然后执行source使之生效

[root@ids-dpdk ~]# vim /etc/profile
添加内容:

export RTE_SDK='/home/dpdk-stable-19.11.14'
export RTE_TARGET=x86_64-native-linuxapp-gcc

[root@ids-dpdk ~]# source /etc/profile

 

创建DPDK绑定脚本dpdk-bind.sh,并赋予执行权限

[root@ids-dpdk usertools]# vim dpdk-bind.sh
[root@ids-dpdk usertools]# chmod -R 775 dpdk-bind.sh

 

dpdk-bind.sh脚本内容如下,根据自己需要修改网卡名称和路径信息

#!/bin/sh

#网卡名
uio=ens1f0

#需要绑定的驱动类型igb_uio或者vfio-pci 
pci_type=igb_uio

#挂载驱动
modprobe uio
insmod /home/dpdk-stable-19.11.14/x86_64-native-linuxapp-gcc/kmod/igb_uio.ko

#关闭网卡
ifconfig $uio down

#绑定网卡到igb_uio
python /home/dpdk-stable-19.11.14/usertools/dpdk-devbind.py --bind=$pci_type $uio

 

设置大页存储,将DPDK绑定脚本加入开机启动项中,编辑/etc/rc.local,根据自己需求修改路径等信息

#!/bin/bash
# THIS FILE IS ADDED FOR COMPATIBILITY PURPOSES
#
# It is highly advisable to create own systemd services or udev rules
# to run scripts during boot instead of using this file.
#
# In contrast to previous versions due to parallel execution during boot
# this script will NOT be run after all other services.
#
# Please note that you must run 'chmod +x /etc/rc.d/rc.local' to ensure
# that this script will be executed during boot.

touch /var/lock/subsys/local

#设置大页存储
echo 1024 > /sys/kernel/mm/hugepages/hugepages-2048kB/nr_hugepages
mkdir /mnt/huge > /dev/null 2>&1
mount -t hugetlbfs nodev /mnt/huge

#网卡绑定DPDK
sh /home/dpdk-stable-19.11.14/usertools/dpdk-bind.sh > /dev/null 2>&1

编辑完成后,执行:wq保存并退出
