Android安装busybox

Android安装Busybox

这个只为开发者用，一般人别用。

最新的busybox已经足够强大，强大到不可想像了添加了很多命令，对开发者来说是极为好用的。

如果你是个拿来主义，把这个下载了，在system分区解压就好了。toolbox中特有的命令还是会保留的，相同的命令会替换。我使用的是armv4指令集的交叉工具链编译的，目的就是尽可能的通用。如果你的Android设备不能用，那么就得自己编译了。（编译好的:http://download.csdn.net/detail/kangear/7564291，将压缩包放到Android手机中，进行第7步解压操作就好了！）

编译一个busybox，前提你装好了交叉工具链，以下就是编译脚本。

#!/bin/sh#@author  : kangear#@function: build busybox static.# 1.download sourcewget http://www.busybox.net/downloads/busybox-1.22.1.tar.bz2 -O busybox.tar.bz2 || exit 1# 2.uncompress and cdtar xvjf busybox.tar.bz2 && cd busybox-1.22.1 || exit 1# 3.configmake defconfig CROSS_COMPILE=arm-linux- || exit 1# 4.modify busybox.linksmake CROSS_COMPILE=arm-linux- LDFLAGS=--static install || exit 1rm _install -rf || exit 1#   4.1 delect linuxrc linesed -i '/linuxrc/d' busybox.links || exit 1#   4.2 sbin usr/bin usr/sbin => binsed -i 's/usr\/sbin/bin/' busybox.links || exit 1sed -i 's/usr\/bin/bin/' busybox.links || exit 1sed -i 's/sbin/bin/' busybox.links || exit 1# 5. build & installmake CROSS_COMPILE=arm-linux- LDFLAGS=--static install || exit 1# 6. tar cvzf# adb push /system/bin & tar xvzf bin.tar.gztar cvzf busybox_bin.tar.gz -C _install/ bin || exit 1# 7. install into Android#   7.1 将/system分区进行remount成可写的#   7.2 将busybox_bin.tar.gz放置到Android文件系统中任何位置#   7.3 tar xvzf busybox_bin.tar.gz -C /system/

另：关于《busybox无法ping域名的解决办法》可以尝试如下实现busybox 中的ping:

先获取地区dns或者路由器上的dns或者getprop中的dns，思路先留在这里，以后有时候再完善。

/ # getprop | grep dns[dhcp.eth0.dns1]: [192.168.100.1][dhcp.eth0.dns2]: [][dhcp.eth0.dns3]: [][dhcp.eth0.dns4]: [][dhcp.wlan0.dns1]: [192.168.2.1][dhcp.wlan0.dns2]: [][dhcp.wlan0.dns3]: [][dhcp.wlan0.dns4]: [][net.change]: [net.eth0.dns2][net.dns1]: [192.168.100.1][net.dnschange]: [4][net.eth0.dns1]: [49.0.0.0][net.eth0.dns2]: [][net.wlan0.dns1]: [49.0.0.0][net.wlan0.dns2]: []
