[[!meta title="Continuous Integration Debian Stretch Setup"]] [[!meta author="Kyllikki"]] [[!meta date="2017-05-28T12:46:14Z"]] [[!toc]] ## Debian 9 (Stretch) 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)` stretch-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` ### Scaleway node Scaleway servers are currently used for ARM64 and armhf workers. Although we have self-hosted hardware for both of these node types these nodes are conveniant alternatives. For AMD64 workers just create zero cost instances on phoenix! Use the scaleway dashboard to create a server of the correct architecture and Debian jessie image (it has to be upgraded currently) a minimal 50G root volume is plenty of storage. once started ssh to the image using the appropriate ssh key `ssh -i .ssh/keys/id_rsa.netsurf root@1.2.3.4` edit \etc\hostname to contain nsciworker17 edit \etc\hosts to set loopback name resolution 127.0.1.1 nsciworker17 127.0.0.1 localhost ::1 localhost ip6-localhost ip6-loopback ff02::1 ip6-allnodes ff02::2 ip6-allrouters 192.168.211.1 ci.netsurf-browser.org 93.93.129.191 vpn.netsurf-browser.org `adduser netsurf` ensure netsurf user has ssh key installed edit /etc/group to add netsurf to sudo group edit /etc/apt/sources/list to be stretch # apt-get update # apt-get dist-upgrade # apt-get clean # halt use dashboard power toggle to force a hard reboot login as netsurf and use `sudo -i` to get root terminal something in the update appears to break journalctl # mkdir -p /var/log/journal # rm /etc/machine-id # systemd-machine-id-setup # systemd-tmpfiles --create --prefix /var/log/journal # service systemd-journald restart edit /etc/ssh/sshd_config to disable password login. ensure you can login using certificates *before* you do this! # To disable tunneled clear text passwords, change to no here!

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-stretch-on-rpi2/ Sjored|http///sjoerd.luon.net/posts/2015/02/debian-stretch-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/stretch-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 Use [[armbian||https://dl.armbian.com/orangepipc/Debian_jessie_default.7z]] - unpack image and write to micro SD card and configure as per banana pi instructions Once installed: - first login as root:1234 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 "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|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.) 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/ stretch/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.

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|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 worker apt sources echo "deb https://ci.netsurf-browser.org/builds/debian/ stretch/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 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/)` stretch/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 - run screen - create jenkins-slave.sh #!/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
