BCC programming 筆記

安裝 BCC 使用 Source Code

For Bionic (18.04 LTS)

Install related libraries and packages

$ sudo apt-get -y install bison build-essential cmake flex git libedit-dev \

libllvm6.0 llvm-6.0-dev libclang-6.0-dev python zlib1g-dev libelf-dev \

iperf3 luajit libluajit-5.1-dev netperf linux-headers-$(uname -r)

Compile BCC source code and install

$ git clone --recursive https://github.com/iovisor/bcc.git

$ git submodule update --recursive

# Or $ git pull --recurse-submodules

$ mkdir bcc/build; cd bcc/build

$ cmake .. -DCMAKE_INSTALL_PREFIX=/usr -DPYTHON_CMD="python python3.8"

$ make -j `nproc`
$ sudo make install 

Quick Start Guide

A Docker container is provided for user to try out bcc.

From your host shell:

docker run -it --rm \
  --privileged \
  -v /lib/modules:/lib/modules:ro \
  -v /usr/src:/usr/src:ro \
  -v /etc/localtime:/etc/localtime:ro \
  --workdir /usr/share/bcc/tools \
  zlim/bcc

[Make] Build the Linux Kernel

This document keeps my previous job that is to deal with re-building Linux Kernel for myself reference:

Modules存放位置:  /lib/modules/$(uname -r)/kernel/

核心檔案放置在:  /usr/src/kernels/`uname -r`/arch/x86/boot/bzImage

第一次進行編譯, 保持乾淨原始碼： make mrproper
其餘的時刻，你想要刪除前一次編譯過程的殘留資料: make clean

開始挑選核心功能： make XXconfig
make menuconfig

make help

[root@www linux-2.6.30.3]# make vmlinux  <==未經壓縮的核心
[root@www linux-2.6.30.3]# make modules  <==僅核心模組
[root@www linux-2.6.30.3]# make bzImage  <==經壓縮過的核心(預設)
[root@www linux-2.6.30.3]# make all      <==進行上述的三個動作


移動核心到 /boot 且保留舊核心檔案
[root@www ~]# cp /usr/src/kernels/linux-2.6.30.3/arch/x86/boot/bzImage \
> /boot/vmlinuz-2.6.30.3vbird  <==實際核心
[root@www ~]# cp /usr/src/kernels/linux-2.6.30.3/.config \
> /boot/config-2.6.30.3vbird   <==建議設定檔也複製備

建立相對應的 Initial Ram Disk (initrd)
mkinitrd -v /boot/initrd-2.6.30.3vbird.img  2.6.30.3vbird

編輯開機選單
vim /boot/grub/menu.lst

[Linux Kernel] How to build Linux kernel on Ubuntu?

The general way to build Linux kernel:

• apt-get install libncurses-dev kernel-package bzip2 make ncurses-dev fakeroot module-init-tools patch 
• apt-get install fakeroot build-essential kernel-package libncurses5 libncurses5-dev
• To find the stable version from https://www.kernel.org/ and download it and tar the tar.bz2 file into /usr/src/
• cd /usr/src/linux-source-3.2.0/   <== it is my case
• make mrproper
• make menuconfig
• make -j 16
• sudo make modules_install install
• sudo update-grub2
• reboot

Booting Menu:

/boot/grub/grub.cfg

Booting Linux Options:

/etc/default/grub


The Ubuntu way to do so:

• make-kpkg clean
• make-kpkg --initrd --append-to-version=danny4400 kernel_image kernel-headers 
• cd ..
• dpkg -i   linux-image-（Push tab button)
• ls -l /boot/
• reboot
