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-19.11.14Suricata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-release2 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_645 [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_647 [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_6412#两个版本号不一致，进行升级并重启13 [root@ids-dpdk ~]# yum -y update kernel kernel-devel14[root@ids-dpdk ~]# reboot15#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_6418 [root@ids-dpdk ~]# uname -r19 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-19.11.14RTE_TARGET=x86_64-native-linuxapp-gcc3. 关闭要绑定的网卡，否则绑定dpdk时不成功
ifconfig ens1f0 down4. 进入到dpdk-19.11.14/usertools目录下
cd/home/dpdk-19.11.14/usertools
执行./dpdk-setup.sh

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 autoconf2、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 objectfile: 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 --dpdk22/3/2023 -- 15:36:51 - <Notice> - --26. (protocol-ff)22/3/2023 -- 15:36:51 - <Notice> - --27. (protocol-ff)22/3/2023 -- 15:36:51 - <Notice> - --28.

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

# In contrast to previous versions due to parallel execution during boot
#thisscript will NOT be run after all other services.
