Debian jessie (8.x) OS install
------------------------------

### amd64 VDS install from media

[[Virtual server setup|virtual_host_server]]

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`

### arm64 VDS install

[[ARM64 virtual server setup|virtual_host_server_arm64]]

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`](http://http.debian.net/debian)` jessie-backports main" > /etc/apt/sources.list.d/backports.list`  
`apt-get update`

-   install updated kernel

`apt-get install linux-image-4.3.0-0.bpo.1-arm64`

### 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|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
-   change /etc/apt/sources.list to point at a local mirror
-   apt-get update
-   apt-get upgrade
-   install sudo package and add netsurf user to sudo group

### Raspberry Pi 2

This system is a quad core ARMv7 Broadcom using the armhf ABI

Used install media from [[http://sjoerd.luon.net/posts/2015/02/debian-jessie-on-rpi2/ Sjored|http///sjoerd.luon.net/posts/2015/02/debian-jessie-on-rpi2/_sjored]]

-   unpack onto micro SD card with bmap-tools

`On any debian-based linux type "sudo apt-get install bmap-tools" and install it.`  
`Then type "sudo bmaptool copy --nobmap 'yourlocation/jessie-rpi2.img' /dev/sdx" (Change yourlocation to the location of the .img file and sdx for the letter where the SD is mounted, if you don't know it type "sudo fdisk -l" and look for it).`

Once installed:

-   first login as root:debian which will need to be immediately changed
-   Prevent package FLASH-KERNEL UPDATING FROM OFFICIAL REPO WITH APT
    PINNING

`'touch /etc/apt/preferences.d/flash-kernel' create a new file`  
`'vi /etc/apt/preferences.d/flash-kernel' edit it an add the following lines to it:`  
`Package: flash-kernel`  
`Pin: origin repositories.collabora.co.uk`  
`Pin-Priority: 1000`  
`'apt-cache policy flash-kernel' check if the package is pinned`

-   change /etc/apt/sources.list to point at a local mirror
-   apt-get update
-   apt-get upgrade
-   adduser netsurf
-   install sudo package and add netsurf user to sudo group

### Orange Pi PC

This system is a quad core ARMv7 allwinner H3 using the armhf ABI

Used "mini" install media from
[[http://www.orangepi.org/orangepibbsen/forum.php?mod=viewthread&tid=342 loboris|http///www.orangepi.org/orangepibbsen/forum.php?mod=viewthread&tid=342_loboris]]

-   unpack image and write to micro SD card and configure as per loboris
    instructions, careful installation steps are not immediately obvious

Once installed:

-   first login as orangepi:orangepi which will need to be immediately
    changed

`* superuser available via sudo -i`

-   change /etc/apt/sources.list to point at a local mirror
-   apt-get update
-   apt-get upgrade
-   alter orangepi user to netsurf by editing

`/etc/group (dont forget to replace orangepi on the sudo group)`  
`/etc/passwd`  
`/etc/shadow`  
`mv /home/orangepi /home/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|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/`](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/`](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/`](http://ci.netsurf-browser.org/builds/debian/)`)`  
`libexpat1-dev`  
`libxml-perl`  
`libxml-xpath-perl`  
`lcov`  
`gcovr (from our repo)`  
`gperf`  
`flex`  
`bison`  
`libpng-dev`  
`libjpeg-dev`  
`libmozjs185-dev`  
`libglib2.0-dev`  
`libcurl4-openssl-dev`  
`liblcms1-dev`  
`libxml2-dev`  
`librsvg2-dev`  
`libmng-dev`  
`libgtk2.0-dev`  
`libmozjs-dev`

### 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:
    -   wget <http://ci.netsurf-browser.org/jenkins/jnlpJars/slave.jar>
    -   run screen
    -   create jenkins-slave.sh

`#!/bin/bash`  
  
`java -Djava.awt.headless=true -jar slave.jar -jnlpUrl `[`http://ci.netsurf-browser.org/jenkins/computer/chimera/slave-agent.jnlp`](http://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`

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")`  
``  
`# 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/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|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/`](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
