实验平台：CentOS Linux release 7.6.1810 (Core)

busybox Version：busybox-1.33.0

一、安装使用

1.官网

https://www.busybox.net/
https://github.com/mirror/busybox
#Github

2.下载

$ wget https://busybox.net/downloads/busybox-1.33.0.tar.bz2

3.解压

$ sudo yum -y install bzip2
$ tar -jxf busybox-1.33.0.tar.bz2
$ cd busybox-1.33.0

3.1 make help

$ make help
#会读取当前路径下的 Makefile.help，确保下载的源码包里有这个
清除(Cleaning):
  clean                 #删除由生成创建的临时文件
  distclean             #删除所有非源文件(包括.config)
  doc-clean             #删除所有生成的文档

构建(Build):
  all                   #创建可执行文件和文档
  busybox               #创建 busybox 命令
  doc                   #创建 docs/BusyBox.{txt,html,1}
  html                  #创建基于html的交叉引用

配置(Configuration):
  allnoconfig           #禁用 .config 中的所有功能，将 .config 设置为最小的通用配置
  allyesconfig          #启用 .config 中的所有功能(参考 defconfig)，将 .config 设置为最大的通用配置
  config                #基于文本的配置器 (of last resort)
  defconfig             #将 .config 设置为通用配置，用这个就足够了
  menuconfig            #交互式 curses-based 配置器，可选，可以加入或去除某些模块
  oldconfig             #resolve any unresolved symbols in .config
  android2_defconfig    # Build for android2
  TEST_noprintf_defconfig # Build for TEST_noprintf
  cygwin_defconfig      # Build for cygwin
  TEST_nommu_defconfig  # Build for TEST_nommu
  android_defconfig     # Build for android
  android_ndk_defconfig # Build for android_ndk
  android_502_defconfig # Build for android_502
  TEST_rh9_defconfig    # Build for TEST_rh9
  freebsd_defconfig     # Build for freebsd


安装(Installation):
  install               #将 busybox 安装到 CONFIG_PREFIX 中
  uninstall             #卸载

开发(Development):
  baseline              #为 bloatcheck 创建 busybox_old
  bloatcheck            #显示新旧版本之间的大小差异
  check                 #为所有程序运行测试套件
  checkhelp             #检查 Config.in 中缺少的帮助项
  randconfig            #生成随机配置
  release               #创建一个分发压缩文件
  sizes                 #显示所有已启用的 busybox 模块的大小
  objsizes              #显示所构建的每个 .o 对象
  bigdata               #显示数据对象，优先显示最大的
  stksizes              #显示堆栈用户, 优先显示最大的

4.编译

$ make defconfig
$ make
#会在当前目录下生成 busybox 二进制可执行文件。编译完成

4.1 编译安装

$ make install
#编译安装后会在当前目录生成一个 _install 文件，里面也有 busybox 的二进制可执行文件，也有一些基础命令的软连，全是软连给 busybox

二、使用 busybox

1.为什么需要用到 busybox

Linux 服务器并不是完全不可攻破的，有些厉害的病毒会修改你的基础命令，你不仔细就很容易上当了。使用 busybox 就完全避免了这个问题

3.busybox 是具备可移植的，只需将 busybox 可执行的二进制文件移至到同一类型的服务器下即可使用
