Debian 9 (Buster) 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"

as root update grub

update-grub2

arm64 VDS install

?ARM64 virtual server setup

Once installed:

  • create netsurf user
  • install sudo package and add netsurf user to sudo group
  • edit /etc/inittab comment pty 3 through 6 and uncomment serial T0
  • enable backports

echo "deb http://http.debian.net/debian buster-backports main" > /etc/apt/sources.list.d/backports.list
apt-get update

Packaged CI worker install

Do a base OS install

The recommended hostname for CI workers is "nsciworker17" this allows us to clearly identify CI worker nodes. Note historically we have used "cislave1" which has been objected to by several users. See 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.)

When configuring a scaleway instance the "Launch method" should be set to "start and stop this node on-demand" with the "Start script" set to perl /usr/bin/pscw.pl start netsurf-ciworker17 and "Stop script" set to perl /usr/bin/pscw.pl stop netsurf-ciworker17. The Availability set to "Take this slave on-line when in demand and off-line when idle" and "in demand delay" set to 0 and "idle delay" set to 15. This will mean the node is turned off and not charged for when idle.

As superuser:

create jenkins user

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

Install https transport

apt-get install apt-transport-https

Add CI server repo to slave apt sources

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

update repos

apt-get update

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

apt-get install ns-ci-worker

edit /etc/default/ns-ci-worker to set the correct url and secret parameters

ensure /opt is setup correctly to allow toolchains to be built on the node 

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@nsciworker12.netsurf-browser.org"

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

scp /home/jenkins/.ssh/id_rsa.pub netsurf@ci.netsurf-browser.org:nsciworker12_id_rsa.pub

exit jenkins user shell

start CI worker daemon

/etc/init.d/ns-ci-worker start

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", "buster", "jessie", "wheezy", "squeeze")

# List of Ubuntu suites.
UBUNTU_SUITES=("vivid" "utopic" "trusty" "saucy" "raring" "quantal" "precise" "oneiric" "natty" "lucid" "hardy")

# Mirrors to use. Update these to your preferred mirror.
DEBIAN_MIRROR="ftp.uk.debian.org"
UBUNTU_MIRROR="mirrors.kernel.org"

# set a default distribution if none is used.
: ${DIST:="$(lsb_release --short --codename)"}

# set the architecture to the host architecture if none set.
: ${ARCH:="$(dpkg --print-architecture)"}

NAME="$DIST"
if [ -n "${ARCH}" ]; then
    NAME="$NAME-$ARCH"
    DEBOOTSTRAPOPTS=("--arch" "$ARCH" "${DEBOOTSTRAPOPTS[@]}")
fi
BASETGZ="/var/cache/pbuilder/$NAME-base.tgz"
DISTRIBUTION="$DIST"
BUILDRESULT="/var/cache/pbuilder/$NAME/result/"
APTCACHE="/var/cache/pbuilder/$NAME/aptcache/"
BUILDPLACE="/var/cache/pbuilder/build/"

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"
    fi
elif $(echo ${UBUNTU_SUITES[@]} | grep -q $DIST); then
    # Ubuntu configuration
    MIRRORSITE="http://$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/buster-armhf/result
# chown root:pbuilder /var/cache/pbuilder/buster-armhf/result
# chmod g+w /var/cache/pbuilder/buster-armhf/result

become jenkins user

su -s/bin/bash - jenkins

create pbuilder base for distribution

sudo DIST=buster pbuilder create

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

sudo DIST=buster 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 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 worker apt sources

echo "deb https://ci.netsurf-browser.org/builds/debian/ buster/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

Manual CI worker install

Caution these instructions may not be up to date.

required packages

config

  • on master jenkins use "manage nodes" to create new node. Ensure "remote fs root" is set to /home/netsurf/jenkins
  • create netsurf user

  • as netsurf user:

    !/bin/bash

    java -Djava.awt.headless=true -jar slave.jar -jnlpUrl https://ci.netsurf-browser.org/jenkins/computer/chimera/slave-agent.jnlp -secret 0123456789abcdef01234567890abcdef

    • 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
