Instruktaż/Tutorial Ubuntu LTS version into your QNAP NAS (chroot/native)

[Silas Mariusz]

Prepare in QNAP NAS QTS GUI:
I. Create user and share name: Backup

II. Install Optware (Development) from QTS App Center

II-1. Once Optware is enabled, use PuTTY or any SSH client and login as admin
II-2. Execute following commands in SSH session:

ipkg install binutils
ipkg install coreutils
ipkg install perl
ipkg install nano mc

III. Prepare and download Ubuntu debootstrap

III-1. Download debootstrap

cd /share/Backup
mkdir -p chroot; cd chroot
wget -c http://mirror.esc7.net/pub/Ubuntu/pool/main/d/debootstrap/debootstrap_1.0.40~precise2_all.deb
ar -x debootstrap_1.0.40~precise2_all.deb
tar xvf data.tar.gz

III-2. Set debootstrap directory path:

export DEBOOTSTRAP_DIR=`pwd`/usr/share/debootstrap

To make sure path is correctly set, execute:

ls $DEBOOTSTRAP_DIR

You should see:

devices.tar.gz   functions   scripts/

III-3. Set env. settings

export ARCH=i386
export RELEASE=precise
export MIRROR=http://pl.archive.ubuntu.com/ubuntu/

If you have 64-bit processor, change i386 to amd64.
You can also change the mirror server by replacing pl to another country code.

IV. Initiate debootstrap

./usr/sbin/debootstrap --arch $ARCH --foreign $RELEASE ./$RELEASE\_$ARCH $MIRROR

V. Download QEMU

wget -c http://launchpadlibrarian.net/118258808/qemu-user-static_1.0.50-2012.03-0ubuntu2.1_amd64.deb
ar -x qemu-user-static_1.0.50-2012.03-0ubuntu2.1_amd64.deb
tar xvf data.tar.gz

VI. Run debootstrap second stage using QEMU arch

cp ./usr/bin/qemu-x86_64-static ./$RELEASE\_$ARCH/usr/bin
export DEBOOTSTRAP_DIR=""
LC_ALL=C LANGUAGE=C LANG=C chroot $RELEASE\_$ARCH /debootstrap/debootstrap --second-stage

VII. Configurue Ubuntu packages

LC_ALL=C LANGUAGE=C LANG=C chroot $RELEASE\_$ARCH dpkg --configure -a

VIII-1. Download Ubuntu apt repository sources list

wget --no-check-certificate https://help.ubuntu.com/12.04/sample/sources.list

All servers in sources.list are located in US, so you can change them:

sed -i "s/us\.archive/pl.archive/g" sources.list

VIII-2. Make backup of the original sources list and use the downloaded one instead:

mv $RELEASE\_$ARCH/etc/apt/sources.list $RELEASE\_$ARCH/etc/apt/sources.list.orig
cp sources.list $RELEASE\_$ARCH/etc/apt/sources.list

IX. Mount essential directories using mountall.sh script (see the end of the post):

./mountall.sh $RELEASE\_$ARCH

X. Install common packages

LC_ALL=C LANGUAGE=C LANG=C chroot $RELEASE\_$ARCH /bin/bash -c "apt-get update; apt-get install vim mc sudo gnupg -y; apt-get update; locale-gen en_US.UTF-8; echo \"Europe/Warsaw\" > /etc/timezone; dpkg-reconfigure -f noninteractive tzdata"

XI. Download and set GPG repository keys

LC_ALL=C LANGUAGE=C LANG=C chroot $RELEASE\_$ARCH apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 3E5C1192

XII. Update apt repository

LC_ALL=C LANGUAGE=C LANG=C chroot $RELEASE\_$ARCH apt-get update

XIII. Enjoy debootstrap

chroot $RELEASE\_$ARCH /bin/bash

XIV. Optional - upgrade packages

dpkg-divert --local --rename --add /sbin/initctl
ln -s /bin/true /sbin/initctl
apt-get update && apt-get upgrade

XV. Optional - install xfce and xrdp
First - set password for root user:

passwd
touch ~/.Xauthority

Second - install xfce:

apt-get install xubuntu-desktop

Third - install xrdp:

apt-get install xrdp

Now you can connect to Ubuntu desktop via Windows Remote Desktop

HAPPY HACKING …

APPEND - Useful scripts:

# ====mountall.sh====
cat > mountall.sh << EOF
#!/bin/bash

if [ -z \$1 ]; then
  CHROOT_PATH=ubuntu
else
  CHROOT_PATH=\$1
fi

DROOT=\`pwd\`/\$CHROOT_PATH

mount -t proc proc \$DROOT/proc
mount --bind /dev \$DROOT/dev
mount -t sysfs sysfs \$DROOT/sys
mount --bind /dev/pts \$DROOT/dev/pts
EOF
chmod +x mountall.sh
# =================

# ====first.sh====
chroot ubutu /bin/bash
apt-get update
apt-get install vim sudo gnupg -y
apt-get updatelocale-gen en_US.UTF-8
echo "Europe/Warsaw" > /etc/timezone
dpkg-reconfigure -f noninteractive tzdata
exit
# =============

III-1. 3. - wrong url: http://mirror.esc7.net/pub/Ubuntu/pool/main/d/debootstrap/debootstrap_1.0.40~precise2_all.deb

Silas, sprawdzisz?
Dzięki.

 

[Silas Mariusz]

To się niczym nie różni od natywnego Debiana.
Anyway... debootstrap_1.0.40~precise2_all.deb [34812 bytes] - Download Mirrors (1/10)

 

[pps]

Niczym? Pytam poważnie. Może chociaż repozytoria jakieś aktualniejsze...
Bo nie wiem, czy faktycznie się za to zabierać.

Nice! Thanks for the info.
