![破解 LD_LIBRARY_PATH 以使用 chroot 中最近的 bash](https://linux22.com/image/217782/%E7%A0%B4%E8%A7%A3%20LD_LIBRARY_PATH%20%E4%BB%A5%E4%BD%BF%E7%94%A8%20chroot%20%E4%B8%AD%E6%9C%80%E8%BF%91%E7%9A%84%20bash.png)
我尝试获取更新版本的bash
from LinuxMint
。
我的盒子里有一个chroot
。Debian Sid
bash
我在早期尝试在包装脚本中做什么PATH
#!/bin/bash
LD_LIBRARY_PATH=/path/to/chroot/usr/lib/x86_64-linux-gnu:/path/to/chroot/lib:/path/to/chroot/lib64:/path/to/chroot/var/lib:/path/to/chroot/usr/lib:/path/to/chroot/usr/local/lib /path/to/chroot/bin/bash "$@"
但我得到:
/home/mevatlave/bin/bash: line 3: 1492488 Segmentation fault (core dumped) LD_LIBRARY_PATH=/path/to/chroot/usr/lib/x86_64-linux-gnu:/path/to/chroot/lib:/path/to/chroot/lib64:/path/to/chroot/var/lib:/path/to/chroot/usr/lib:/path/to/chroot/usr/local/lib /path/to/chroot/bin/bash "$@"
从 chroot 开始:
% ldd /bin/bash
linux-vdso.so.1 (0x00007fff237fc000)
libtinfo.so.6 => /lib/x86_64-linux-gnu/libtinfo.so.6 (0x00007f94de839000)
libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007f94de658000)
/lib64/ld-linux-x86-64.so.2 (0x00007f94de9af000)
可行吗?

我可以运行这个:
#!/bin/bash
LANG=C
LD_LIBRARY_PATH=/path/to/chroot/usr/lib/x86_64-linux-gnu:/path/to/chroot/lib:/path/to/chroot/lib64:/path/to/chroot/var/lib:/path/to/chroot/usr/lib:/path/to/chroot/usr/local/lib /path/to/chroot/lib/x86_64-linux-gnu/ld-linux-x86-64.so.2 /path/to/chroot/bin/bash "$@"
但是当我跑步时bash --version
,我得到:

我怀疑你的主动态链接器太旧了,你需要使用 chroot 的:
LD_LIBRARY_PATH=/path/to/chroot/usr/lib/x86_64-linux-gnu:/path/to/chroot/lib:/path/to/chroot/lib64:/path/to/chroot/var/lib:/path/to/chroot/usr/lib:/path/to/chroot/usr/local/lib /path/to/chroot/lib64/ld-linux-x86-64.so.2 /path/to/chroot/bin/bash

好的,找到了一个解决方法,可以避免我编译bash
以及将来需要维护它:
来自 chroot
# apt install bash-static
然后,我的升级脚本LinuxMint
:
#!/bin/bash
if mount | grep -q "/home/sid-chroot"; then
chroot /home/sid-chroot <<< 'apt-get -yy update; apt-get -yy upgrade'
else
debian-sid <<< 'apt-get -y update; apt-get -y upgrade'
fi
apt update
apt-get install zsh
apt-get -y upgrade
zsh<<EOF
mv /bin/bash /bin/bash.origin
mv /usr/bin/bash /usr/bin/bash.origin &>/dev/null
cp -a /home/sid-chroot/bin/bash-static /bin/bash
cp -a /home/sid-chroot/bin/bash-static /usr/bin/bash
EOF
