在N1的OpenWRT上使用debootstrap安装debia

1. 创建磁盘镜像

cd /mnt/data
dd if=/dev/zero of=debian.img bs=1M count=1024
mkfs.ext4 debian.img
mkdir /debian
mount debian.img /debian

2. 安装debian

opkg install debootstrap
/bin/debootstrap --arch arm64 stable /debian http://ftp.debian.org/debian

3. 进入debian环境

mount -o bind /dev /debian/dev
mount -o bind /dev/pts /debian/dev/pts
mount -o bind /proc /debian/proc
mount -o bind /sys /debian/sys
chroot /debian /bin/bash

4. debian环境下

apt update
apt install vim
apt install locales
dpkg-reconfigure locales
dpkg-reconfigure tzdata
export LC_ALL=en_US.UTF-8
export LANG=en_US.UTF-8
export LANGUAGE=en_US.UTF-8

5. 安装桌面环境及VNCServer

tasksel
mate
apt install default-jdk
apt install tightvncserver
vncserver

6. xstartup配置

#!/bin/sh

unset DBUS_SESSION_BUS_ADDRESS
[ -x /etc/vnc/xstartup ] && exec /etc/vnc/xstartup
[ -r $HOME/.Xresources ] && xrdb $HOME/.Xresources
xsetroot -solid grey
vncconfig -iconic &
#x-terminal-emulator -geometry 80x24+10+10 -ls -title "$VNCDESKTOP Desktop" &
x-window-manager &
mate-session &

7. start-debian.sh脚本

#!/bin/sh

PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/opt/sbin:/opt/bin \
HOME=/root \
SHELL=/bin/bash \
TERMINFO=/usr/share/terminfo \
TEMP=/tmp \
TMP=/tmp \
LANG=en.US_UTF-8 \
LANGUAGE=en.US_UTF-8 \
LC_ALL=en.US_UTF-8 \
`which chroot` /debian /bin/bash --login

8. /etc/init.d/debian脚本

#!/bin/sh /etc/rc.common

START=99
STOP=10

        done
    fi

# You can add mounting of your device strorages here, if you need.
# For QNAP it may look something like
# mkdir -p $CHROOT_DIR/media/disk1
# mount -o bind /share/HDA_DATA $CHROOT_DIR/media/disk1
# or
# mount -o bind /share/CACHEDEV1_DATA $CHROOT_DIR/media/disk1
