手机上手动安装功能强大的Linux工具Busybox

BusyBox 是一个集成了三百多个最常用linux命令和工具的软件。功能便捷、强大。

安装需要有root权限

查询并下载自己手机的CPU型号及对应busybox二进制文件：

c:tmpfastboot>adb shell
shell@GiONEE_GBL7319:/ $ cat /proc/cpuinfo
Processor       : AArch64 Processor rev 3 (aarch64)
processor       : 0
BogoMIPS        : 26.00

Features        : fp asimd aes pmull sha1 sha2 crc32
CPU implementer : 0x41
CPU architecture: AArch64
CPU variant     : 0x0
CPU part        : 0xd03
CPU revision    : 3

Hardware        : MT6735

AArch64：对应的是ARMv8-A架构，引入的64位指令集，向后兼容基于32位指令集。

下载ARMV8相关的busybox二进制文件：busybox-armv8l

下载地址：
https://busybox.NET/downloads/binaries/

对应文件：busybox-armv8l

安装方法：

adb root              以root来运行
adb remount       重新以读写方式挂载系统
adb push c:tmpbusybox-armv8l   /system/xbin
adb shell
cd /system/xbin
chmod  755  busybox-armv8l           改权限
./busybox-armv8l    --install             安装

有些版本低，前2个命令没有，出现以下问题：error: device not found

c:tmpfastboot>adb shell
shell@GiONEE_GBL7319:/ $ adb root
* daemon not running. starting it now on port 5038 *
* daemon started successfully *
error: device not found
1|shell@GiONEE_GBL7319:/ $ adb remount
error: device not found

c:tmpfastboot>adb push c:/tmp/busybox-armv8l  /system/xbin
adb: error: fAIled to copy 'c:/tmp/busybox-armv8l' to '/system/xbin/busybox-armv8l': remote Permission denied
c:/tmp/busybox-armv8l: 0 files pushed. 0.4 MB/s (131056 bytes in 0.342s)

此时可先将文件传到临时目录： /data/local/tmp ，在用移动mv命令

c:tmpfastboot>adb push c:/tmp/busybox-armv8l  /data/local/tmp
c:/tmp/busybox-armv8l: 1 file pushed. 0.4 MB/s (1148524 bytes in 3.113s)

1|shell@GiONEE_GBL7319:/ $ su
root@GiONEE_GBL7319:/ # mv  /data/local/tmp/busybox-armv8l   /system/xbin

将/system重新挂载为可读写：(可选)

先查/system挂载对应的文件目录(device)：可用如下命令

• cat /proc/mounts
• mount

root@GiONEE_GBL7319:/system/xbin # cat /proc/mounts
rootfs / rootfs rw,seclabel 0 0
tmpfs /dev tmpfs rw,seclabel,nosuid,relatime,mode=755 0 0
devpts /dev/pts devpts rw,seclabel,relatime,mode=600 0 0
proc /proc proc rw,relatime 0 0
sysfs /sys sysfs rw,seclabel,relatime 0 0
selinuxfs /sys/fs/selinux selinuxfs rw,relatime 0 0
none /acct cgroup rw,relatime,cpuacct 0 0
none /sys/fs/cgroup tmpfs rw,seclabel,relatime,mode=750,gid=1000 0 0
tmpfs /mnt/asec tmpfs rw,seclabel,relatime,mode=755,gid=1000 0 0
tmpfs /mnt/obb tmpfs rw,seclabel,relatime,mode=755,gid=1000 0 0
none /dev/cpuctl cgroup rw,relatime,cpu 0 0
tmpfs /mnt/media_rw tmpfs rw,seclabel,relatime,mode=755,uid=1000,gid=1000 0 0
tmpfs /storage/usbotg tmpfs rw,seclabel,relatime,mode=755,uid=1000,gid=1000 0 0
tmpfs /storage/emulated tmpfs rw,seclabel,relatime,mode=755,uid=1023,gid=1023 0 0
/dev/block/platform/mtk-msdc.0/by-name/system /system ext4 rw,seclabel,noatime,data=ordered 0 0

对应目录(device)是：
/dev/block/platform/mtk-msdc.0/by-name/system

重新挂载成可读写：rw是读写，ro是只读（默认）

root@GiONEE_GBL7319:/ # mount -o remount -rw  /dev/block/platform/mtk-msdc.0/by-name/system  /system

或用：root@GiONEE_GBL7319:/ # mount -o remount, rw /system

修改属性：为可执行，chmod 755
/system/xbin/busybox-armv8l

126|root@GiONEE_GBL7319:/ # ls -l /system/xbin/busybox-armv8l
-rw-rw-rw- shell    shell     1148524 2022-01-27 22:12 busybox-armv8l
root@GiONEE_GBL7319:/ # chmod 755  /system/xbin/busybox-armv8l

安 装：./busybox-armv8l --install

127|root@GiONEE_GBL7319:/ # cd /system/xbin
1|root@GiONEE_GBL7319:/system/xbin # ./busybox-armv8l --install
