CentOS编译安装Busybox

1.下载busybox

wget -N -P /opt https://busybox.net/downloads/busybox-1.31.0.tar.bz2 -C /opt

2.安装依赖包

yum -y install gcc gcc-c++ glibc glibc-devel pcre pcre-devel openssl openssl-devel systemd-devel zlib-devel libmcrypt-devel glibc-static ncurses-devel

3.加压并编译安装

# cd /opt
# tar -jxvf busybox-1.31.0.tar.bz2 &&  cd busybox-*
# make menuconfig
选择settings-->Build static binary (no shared libs)选择，保存退出
# make
# l.             //此时在此目录下多出了一个.config的文件
.config  .config.old  .indent.pro .tmp_versions

# ./busybox ls   //编译完成，测试
bin    data   etc    lib    media  opt    root   sbin   sys    usr
boot   dev    home   lib64  mnt    proc   run    srv    tmp    var

# make install

注：使用make install后生成一个_install文件夹，里面存放各种软链接，指向为busybox，将_install移走就能使用了
