Debian jessie (8.x) OS install

amd64 VDS install from media

Virtual server setup

Install minimal system from netinst CD (attached when VDS is created on phoenix) Config options:

  • In the "role" selection select "ssh server" and "system utilities" only.
  • The whole disc default partitioning is fine
  • The base user the install insists on creating should be the netsurf user.
  • Boot loader in MBR

Once installed:

  • install sudo package and add netsurf user to sudo group
  • edit /etc/default/grub

GRUB_CMDLINE_LINUX="console=tty0 console=ttyS0,115200n8"

# update-grub2

Banana Pi

This system is a dual core ARMv7 allwinner using the armhf ABI

Used the install SD media from ?http://www.igorpecovnik.com/2014/09/07/banana-pi-debian-sd-image/ Igor Pecovnik

  • unzip and write raw file to full size SD card.

Once installed:

  • first login as root:1234 which will need to be immediately changed
  • use the nand-sata-install script and moved the install to sata disc. The drive needs to be a clean drive with a recognised partition table (DOS or GPT) and a single partition where the OS will be installed.
  • edit /etc/init.d/armhwinfo to remove the toilet dynamic MOTD banner
  • (re)move /etc/bash.bashrc.custom as it issues a lot of unnecessary commands
  • adduser netsurf

Packaged CI worker install

Do a base OS install

The recommended hostname for CI workers is "ciworker13" this allows us to clearly identify CI worker nodes. Note historically we have used "cislave1" which has been objected to by several users. See ?https://wiki.debian.org/HowTo/ChangeHostname changing hostname on how to achive this.

On master jenkins use "manage nodes" to create new node. Ensure "remote fs root" is set to /var/lib/jenkins add variable JENKINS_HOME set to /var/lib/jenkins

Note: replace arm64 with architecture name as required (armhf etc.)

As superuser:

  • create jenkins user

adduser --system --group --home /var/lib/jenkins/ --disabled-login jenkins

  • Add CI server repo to slave apt sources

echo "deb http://ci.netsurf-browser.org/debian/ jessie/amd64/" >> /etc/apt/sources.list.d/netsurf-browser.list

  • update repos

apt-get update

  • install ns-ci-worker package. accept the large package list and the unsigned package install for gcovr and ns-ci-slave

apt-get install ns-ci-worker

  • edit /etc/default/ns-ci-worker to set the correct url and secret parameters
  • If toolchains are to be built on the node ensure /opt is setup correctly

mkdir -p /opt/netsurf
chown jenkins:jenkins /opt/netsurf

  • become jenkins user

su -s/bin/bash - jenkins

  • create ssh keypair (accept defaults - no password)

ssh-keygen -t rsa -C "netsurf@cislave12.netsurf-browser.org"

  • copy .ssh/id_rsa.pub from slave to jenkins master node and append to /home/netsurf/.ssh/authorized_keys

scp /home/jenkins/.ssh/id_rsa.pub netsurf@ci.netsurf-browser.org:ciworker12_id_rsa.pub

  • exit jenkins user shell
  • start CI worker daemon

/etc/init.d/ns-ci-worker start

Manual CI worker install

required packages

The Netsurf repository has necessary updated packages in it and can be accessed by doing the following:

  • Add CI server repo to slave apt sources

echo "deb http://ci.netsurf-browser.org/builds/debian/ jessie/amd64/" >> /etc/apt/sources.list

  • update repos

apt-get update

use apt to install these packages:

openjdk-7-jre-headless 
screen 
build-essential
ccache
clang
git
pkg-config
check
doxygen
libjson0-dev (from our repo - needs bugfixes http://ci.netsurf-browser.org/builds/debian/)

libxml-perl
libxml-xpath-perl
lcov
gcovr (from our repo)
gperf

    • run jenkins-slave.sh
    • create new screen tab
    • create ssh keypair (accept defaults - no password)

ssh-keygen -t rsa -C "netsurf@cislave0.netsurf-browser.org"

    • copy .ssh/id_rsa.pub from slave to jenkins master node and append to /home/netsurf/.ssh/authorized_keys

scp ci.netsurf-browser.org:.ssh/id_rsa.pub .id_rsa.pub
cat id_rsa.pub >> .ssh/authorized_keys

    • copy .ssh/id_rsa.pub from master node to slave and append to /home/netsurf/.ssh/authorized_keys
    • create reverse-ssh.sh (change tunnel port number!)

#!/bin/sh

ssh -R 22224:localhost:22 netsurf@ci.netsurf-browser.org 'bash -c "while true; do echo .; sleep 60; done"'

    • run reverse-ssh.sh
    • on the master create a shell script to use the ssh tunnel connection, thus firewalls etc are moot as long as the slave can connect to the master

ssh netsurf@localhost -p 22223

Pbuilder setup

This allows a worker to build Debian packages. The worker should be installed as a normal CI worker node and then:

as superuser on node:

  • apt-get install pbuilder
  • addgroup pbuilder
  • addgroup jenkins pbuilder
  • create /etc/sudoers.d/pbuilder

jenkins         ALL = NOPASSWD:/usr/sbin/pbuilder

  • visudo and alter Defaults

Defaults        env_reset,env_keep="DIST ARCH"

  • replace /etc/pbuilderrc

# this is your configuration file for pbuilder.
# the file in /usr/share/pbuilder/pbuilderrc is the default template.
# /etc/pbuilderrc is the one meant for overwriting defaults in
# the default template
#
# read pbuilderrc.5 document for notes on specific options.
# List of Debian suites.
DEBIAN_SUITES=("sid", "stretch", "jessie", "wheezy", "squeeze")
`# List of Ubuntu suites.`
`UBUNTU_SUITES=("vivid" "utopic" "trusty" "saucy" "raring" "quantal" "precise" "oneiric" "natty" "lucid" "hardy")`

`if [ -n "${ARCH}" ]; then`

`    DEBOOTSTRAPOPTS=("--arch" "$ARCH" "${DEBOOTSTRAPOPTS[@]}")`
`fi`
`BASETGZ="/var/cache/pbuilder/$NAME-base.tgz"`

if $(echo ${DEBIAN_SUITES[@]} | grep -q $DIST); then
    # Debian configuration
    MIRRORSITE="http://$DEBIAN_MIRROR/debian/"
    COMPONENTS="main contrib non-free"
    if $(echo "$STABLE_CODENAME stable" | grep -q $DIST); then
        OTHERMIRROR="$OTHERMIRROR | deb $MIRRORSITE $STABLE_BACKPORTS_SUITE $COMPONENTS"

    # Ubuntu configuration
    MIRRORSITE="http://$UBUNTU_MIRROR/ubuntu/"
    COMPONENTS="main restricted universe multiverse"
else
    echo "Unknown distribution: $DIST"
    exit 1
fi

The architecture is assumed to be the native one from

dpkg --print-architecture

This can be set by passing ARCH to pbuilder (useful for i386 maybe?)

for each distribution this node will build for:

  • create pbuilder result directory and set ownership permissions

mkdir -p /var/cache/pbuilder/jessie-armhf/result
chown root:pbuilder /var/cache/pbuilder/jessie-armhf/result
chmod g+w /var/cache/pbuilder/jessie-armhf/result

  • become jenkins user

su -s/bin/bash - jenkins

  • create pbuilder base for distribution

sudo DIST=jessie pbuilder create

  • if desired additional packages and config can be made to the base with

sudo DIST=jessie pbuilder login --save-after-login

distcc worker node

Do a basic OS install but *not* a CI worker setup.

A recommended hostname for distcc worker is something like "cicpu0" this allows us to use systems as processing node for other purposes than just distcc in future. See debians ?https://wiki.debian.org/HowTo/ChangeHostname changing hostname on how to achive this.

The Netsurf repository has necessary updated packages in it and can be accessed by doing the following:

  • Add CI server repo to slave apt sources

echo "deb http://ci.netsurf-browser.org/builds/debian/ jessie/amd64/" >> /etc/apt/sources.list

  • update repos

apt-get update

  • use apt to install these packages:

build-essential
gcc
clang
distcc

  • edit /etc/default/distcc

STARTDISTCC="true"
ALLOWEDNETS="192.168.211.0/24"
LISTEN="0.0.0.0"
JOBS="8"

  • start the service

service distcc start

  • ensure the client has hosts set to use the new worker
