【安裝檔案】TRex流量分析儀保姆級安裝指南--基於VMware虛擬機器器（ubantu18.04@Intel 82545EM）
2022-11-10 21:00:10
前言
既然你已經知道TRex並嘗試搜尋它的安裝教學，這意味著你有一定的基礎知識（至少知道自己需要什麼）。因此本文對於TRex的介紹部分會偏少
本次主要為TRex安裝過程的一次記錄（版本為v3.0.0），我會整理一些遇到的問題與解決思路，希望對各位有所幫助。
簡介
Cisco開源的一個使用DPDK發包的高效能測試儀。
主要的工作原理概括如下：
- 使用scapy來構建封包模板；或者從pcap檔案中讀取封包模板；
- 利用dpdk傳送封包；（重寫指定變化的部分）
其兼具了python構建流的效率和dpdk發包的高效能。
TRex安裝
TRex是一個Linux環境下的軟體，安裝環境無非兩種：物理機和虛擬機器器
本文主要基於虛擬機器器介紹TRex的安裝
而使用虛擬機器器又可以分為兩種安裝環境：
-
本地虛擬機器器
基於本地VMware構建的虛擬機器器環境
-
遠端伺服器虛擬機器器
基於VMware EXCI構建的遠端虛擬機器器環境
兩種方式最大的不同在網路卡新增時，VMware EXCI需要使用ifcofig讓系統識別出網路卡，詳見[7]
其餘的流程差不多，本文著重介紹本地VMware基於ubantu18.04安裝TRex的流程
如果你在VMware EXCI安裝遇到了問題，也歡迎留言討論
基於本地虛擬機器器的安裝過程
如何獲得一個本地VMware虛擬機器器（包括換源等操作）請自行Google或參考[1]
我使用的VMware版本是VMwareWorkStation PRO16，虛擬機器器映象為Ubantu18.04桌面版
虛擬機器器設定
先列一下我使用的虛擬機器器設定（圖掛了看錶）
裝置 摘要
記憶體 8 GB
處理器 4
硬碟(SCSI) 35 GB
CD/DVD 2 (SATA) 自動檢測
CD/DVD (SATA) 自動檢測
軟碟 自動檢測
網路介面卡 NAT
網路介面卡2 NAT
網路介面卡3 NAT
USB控制器 存在
音效卡 自動檢測
印表機 存在
顯示器 自動檢測
注：因為安裝之後的測試需要用到多塊網路卡，故此處新增了3塊網路卡，一塊作為Linux核心的主網路卡，其餘兩塊用於繫結uio驅動進行測試。
虛擬機器器的網路卡可以隨時新增或刪除，只要保證其模式始終為NAT即可
虛擬機器器設定完成後，推薦使用VScode連線並操作，因為之後涉及對組態檔的修改，會比較方便。具體請看：https://www.cnblogs.com/DAYceng/p/16867325.html
當然也可以直接在VMware提供的介面中操作
獲取TRex
在你喜歡的目錄下建立一個資料夾存放安裝檔案
mkdir trex
cd trex
下載TRex最新分支並解壓
root@ubuntu:/root/trex# wget --no-check-certificate https://trex-tgn.cisco.com/trex/release/latest
root@ubuntu:/root/trex# tar -zxvf latest
注：latest檔案下載過程很慢，掛梯子也很慢，可以先在本地存取https://trex-tgn.cisco.com/trex/release/latest把檔案下載下來再傳到虛擬機器器上
得到以下目錄
root@ubuntu:/root/trex# ls
latest v3.00
進入解壓後的資料夾，使用指令碼檢視當前可用的網路卡
root@ubuntu:/root/trex# cd v3.00
root@ubuntu:/root/trex/v3.00#
root@ubuntu:/root/trex/v3.00#sudo ./dpdk_setup_ports.py -s

如果之前新增了網路卡，這裡就可以看見有3個網路卡（沒新增的現在再加也行），* Active *為Linux核心正在使用的網路卡，另外兩張是未啟用的網路卡（先不要啟用），如果有需要請檢視[7]
安裝dpdk
實際上這部分和獨立安裝dpdk差別不大
前面的簡介中有提到，TRex可以大致分為兩部分，一部分是用來構造封包的【基於scapy】，另一部分則是用來傳送封包【基於DPDK】
安裝gcc環境
現在我們先來安裝DPDK部分，首先安裝gcc環境
root@ubuntu:/root/trex/v3.00#
sudo apt install build-essential
sudo apt install make
sudo apt-get install libnuma-dev
下載dpdk
root@ubuntu:/root/trex/v3.00# wget http://fast.dpdk.org/rel/dpdk-18.11.9.tar.xz
root@ubuntu:/root/trex/v3.00# tar xvJf dpdk-18.11.9.tar.xz
root@ubuntu:/root/trex/v3.00# cd dpdk-stable-18.11.9/
root@ubuntu:/root/trex/v3.00/dpdk-stable-18.11.9#
新增環境變數
在dpdk的檔案目錄下設定環境變數，否則會導致之後用指令碼安裝dpdk構建環境時出錯
root@ubuntu:/root/trex/v3.00/dpdk-stable-18.11.9# export RTE_SDK=`pwd`
root@ubuntu:/root/trex/v3.00/dpdk-stable-18.11.9# export DESTDIR=`pwd`
root@ubuntu:/root/trex/v3.00/dpdk-stable-18.11.9# export RTE_TARGET=x86_64-default-linuxapp-gcc
載入uio驅動
# 載入uio驅動
root@ubuntu:/root/trex/v3.00/dpdk-stable-18.11.9# modprobe uio
使用指令碼安裝dpdk
使用dpdk-setup.sh指令碼進行安裝
root@ubuntu:/root/trex/v3.00/dpdk-stable-18.11.9# ./usertools/dpdk-setup.sh

步驟三
測試，選擇[27]和[28]
Option: 27
Enter hex bitmask of cores to execute test app on
Example: to execute app on cores 0 to 7, enter 0xff
bitmask: 0x3
Launching app
sudo: x86_64-default-linuxapp-gcc/app/test: command not found
Press enter to continue ...
Option: 28
Enter hex bitmask of cores to execute testpmd app on
Example: to execute app on cores 0 to 7, enter 0xff
bitmask: 0x3
Launching app
sudo: x86_64-default-linuxapp-gcc/app/testpmd: command not found
這兩個測試都有可能會出現"command not found"的報錯提醒，
其中[27]出現該錯誤不用理會，[28]若出現的話，可以退出指令碼（選[35]），到/[你的DPDK目錄]/x86_64-native-linuxapp-gcc/app下找到testpmd，再執行它進行測試即可，若無以外會得到以下輸出

執行testpmd可能出現的問題
1、HugePage容量問題
當執行測試時或者testpmd，可能會遇到如下問題
root@ubuntu:/root/trex/v3.00/dpdk-stable-18.11.9/x86_64-native-linuxapp-gcc/app# ./testpmd
EAL: Detected 8 lcore(s)
EAL: Detected 1 NUMA nodes

EAL: No free hugepages reported in hugepages-2048kB

2: [./testpmd(__rte_panic+0xbb) [0x47eb09]]
1: [./testpmd(rte_dump_stack+0x2b) [0x5c8a1b]]
Aborted (core dumped)
這說明Hugepage不夠用，可以先檢視系統記憶體狀況
root@ubuntu:/root/trex/v3.00/dpdk-stable-18.11.9/x86_64-native-linuxapp-gcc/app# cat /proc/meminfo | grep Huge
AnonHugePages: 0 kB
ShmemHugePages: 0 kB
FileHugePages: 0 kB

HugePages_Free: 775
HugePages_Rsvd: 0
HugePages_Surp: 0
Hugepagesize: 2048 kB
Hugetlb: 2097152 kB
如果不夠用可以按需修改
root@ubuntu:/root/trex/v3.00/dpdk-stable-18.11.9/x86_64-native-linuxapp-gcc/build/kernel/linux# echo 2048 > /sys/kernel/mm/hugepages/hugepages-2048kB/nr_hugepages

HugePages_Free: 1199
HugePages_Rsvd: 0
HugePages_Surp: 0
Hugepagesize: 2048 kB
Hugetlb: 2965504 kB
此時再去指令碼中執行測試[28]會得到以下輸出
Option: 28
Enter hex bitmask of cores to execute testpmd app on
Example: to execute app on cores 0 to 7, enter 0xff
bitmask: 0x3

testpmd>
這是正常的，包括"EAL: No free hugepages reported in hugepages-1048576kB"提示也是正常的
之後再去/[你的DPDK目錄]/x86_64-native-linuxapp-gcc/app下執行testpmd可得到與本文一致的結果
2、82545EM 虛擬網路卡問題
若物理機的網路卡為82545EM，使用VMware建立虛擬機器器後，該網路卡對於dpdk的支援會存在問題，
報錯為"Eal:Error reading from file descriptor 33: Input/output error"
具體見[5]的分析
為了跳過dpdk對82545EM某些相容性的檢測，我們需要修改dpdk的組態檔igb_uio.c
該檔案位於/[你的DPDK目錄]//kernel/linux/igb_uio/igb_uio.c下
使用vscode開啟該檔案（或者vim也行）
定位到
if (pci_intx_mask_supported(udev->pdev) ，大概是第260行
然後修改為if (pci_intx_mask_supported(udev->pdev)|| 1)，如下：
#endif
/* falls through - to INTX 修改*/
case RTE_INTR_MODE_LEGACY:
if (pci_intx_mask_supported(udev->pdev)|| 1) {
dev_dbg(&udev->pdev->dev, "using INTX");
udev->info.irq_flags = IRQF_SHARED | IRQF_NO_THREAD;
udev->info.irq = udev->pdev->irq;
udev->mode = RTE_INTR_MODE_LEGACY;
break;
}
然後重新執行編譯
modprobe uio
並重新執行指令碼中的[15]項，安裝環境
解決
啟動TRex
編輯組態檔
sudo cp cfg/simple_cfg.yaml /etc/trex_cfg.yaml
sudo vim /etc/trex_cfg.yaml
- port_limit : 2
version : 2
#List of interfaces. Change to suit your setup. Use ./dpdk_setup_ports.py -s to see available options
interfaces : ["02:06.0","02:07.0"] #將之前繫結uio驅動的網路卡新增到這裡
port_info : # Port IPs. Change to suit your needs. In case of loopback, you can leave as is.
- ip : 1.1.1.1
default_gw : 2.2.2.2
- ip : 2.2.2.2
default_gw : 1.1.1.1
開啟兩個終端，分別執行以下指令啟動stateless伺服器
root@ubuntu:/root/trex/v3.00# sudo ./t-rex-64 -i
root@ubuntu:/root/trex/v3.00# sudo ./trex-console
效果如下（圖掛了看程式碼塊）
