Termux 解决使用ps -ef出现关于挂载/proc分区的错误

---

报错环境

---

设备：安卓手机

运行应用：ZeroTermux v0.118.38.1( termux也一致 )

系统：termux中使用国光大佬脚本安装的Ubuntu 18.04.6 LTS

架构：aarch64

内核版本：4.14.186-perf-ga9792052ef2e

---

报错情况

---

使用命令(在root用户情况下)：

ps

出现了如下报错：

Error: /proc must be mounted
  To mount /proc at boot you need an /etc/fstab line like:
      proc   /proc   proc    defaults
  In the meantime, run "mount proc /proc -t proc"

包括安装宝塔面板时也出现了该报错

解决方案

参考b站文章：Termux 上装 GNU/Linux 报错“Error: /proc must be mounted” - 哔哩哔哩 (bilibili.com)

伪造/proc分区下的五个文件，分别为locdavg,stat,uptime,version,vmstat这五个文件

先在/data/data/com.termux目录下创建这五个文件，例如：

cd /data/data/com.termux

注意：使用前先退回到Termux自带的原生系统(使用"exit"命令退出)

然后写入内容：

locdavg 文件

echo '0.12 0.07 0.02 2/165 765' > ./locdavg

stat 文件

echo -e 'cpu 1957 0 2877 93280 262 342 254 87 0 0\ncpu0 31 0 226 12027 82 10 4 9 0 0\ncpu1 45 0 664 11144 21 263 233 12 0 0\ncpu2 494 0 537 11283 27 10 3 8 0 0\ncpu3 359 0 234 11723 24 26 5 7 0 0\ncpu4 295 0 268 11772 10 12 2 12 0 0\ncpu5 270 0 251 11833 15 3 1 10 0 0\ncpu6 430 0 520 11386 30 8 1 12 0 0\ncpu7 30 0 172 12108 50 8 1 13 0 0\nintr 127541 38 290 0 0 0 0 4 0 1 0 0 25329 258 0 5777 277 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0\nctxt 14022\nbtime 1680020856\nprocesses 772\nprocs_running 2\nprocs_blocked 0\nsoftirq 75663 0 5903 6 25375 10774 0 243 11685 0 21677' > ./stat

然后就在proot启动脚本中添加挂载选项：

结构-b 文件路径:/proc/文件名

例：-b /data/data/com.termux/stat:/proc/stat

以国光大佬脚本制作的系统为例：

sed -i '15a command+=" -b /data/data/com.termux/uptime:/proc/uptime"\ncommand+=" -b /data/data/com.termux/vmstat:/proc/vmstat"\ncommand+=" -b /data/data/com.termux/version:/proc/version"\ncommand+=" -b /data/data/com.termux/stat:/proc/stat"\ncommand+=" -b /data/data/com.termux/loadavg:/proc/locdavg"' ~/Termux-Linux/Ubuntu/start-ubuntu.sh

然后重新弄进入Ubuntu系统中即可解决挂载proc分区的问题
