Black&White Project/Compilation Farm/Setup

Organization

The Compilation Farm is installed on the download.kiwix.org server. It is organized as:

• A buildbot master running as user buildbot on the server.
• A set of VirtualBox VMs running buildbot slaves.
  • ubuntu32: i686 deb, i686 static
  • ubuntu64: x86_64 deb, x86_64 static
  • macosx: universal (i386+x86_64) dmg with app.
  • win32: i386 windows static
  • win64: x64 windows static
  • fedora: i686 sugar static
  • arm: armel kiwix-serve static

Master Setup

• Install required packages

# apt-get install build-essential subversion zip unzip python-pip vim python-dev
pip install virtualenv virtualenvwrapper

• Create user buildbot
• Log-in as user buildbot
• Edit .bashrc and add at the end

export EDITOR="vim -v"

export WORKON_HOME=~/envs
source /usr/local/bin/virtualenvwrapper.sh

• Log-out then log-in to enable virtualenvwrapper
• Create virtualenv

mkvirtualenv --no-site-packages buildbot
mkdir -p buildbot && cd buildbot

• Install builbot and create master

easy_install buildbot
buildbot create-master master

• Deploy configuration

svn co https://kiwix.svn.sourceforge.net/svnroot/kiwix/buildbot/ code
cd master && ln -sf ../code/master.cfg master.cfg && cd -
cp code/secret_pass.py master/secret_pass.py

• Edit the password file in master/secret_pass.py
• Start the master

buildbot start master

• Create an nginx proxy at /etc/nginx/sites-available/buildbot.kiwix.org

server {
  listen localhost:81;
  listen 88.190.13.50:80;
  server_name buildbot.kiwix.org;

  access_log off;

  proxy_buffering off;
  proxy_max_temp_file_size 0;

  set_real_ip_from 127.0.0.1;
  set_real_ip_from 88.190.13.50;
  real_ip_header X-Forwarded-For;

  location / {
    proxy_set_header X-Real-IP  $remote_addr;
    proxy_set_header X-Forwarded-For $remote_addr;
    proxy_pass http://localhost:8010;
    proxy_set_header Host $host;
  }
}

Automatic Startup

• crontab -e on builbot user

@reboot /home/buildbot/envs/buildbot/bin/buildbot start /home/buildbot/buildbot/master

Slave Setup

buildbot slave does not require much: a working python/setuptools environnment.

Linux Slave Setup

• Create a VirtualBox VM (20GB of storage - dynamic)
• Install Ubuntu 10.04.4 (Newer versions of Ubuntu uses a recent glibc)
• Select OpenSSH server during install.
• Create a regular user (dev)
• Use whole disk partitioning
• Install packages:

# apt-get install --fix-missing build-essential autoconf automake libtool pkg-config fastjar libssl-dev libexpat1-dev libxml2-dev libgnutls-dev libgpg-error-dev libgcrypt-dev uuid-dev libuuid1 subversion zip unzip python-pip vim python-dev

• Install python tools

# pip install virtualenv virtualenvwrapper

From now, you won't need root privileges anymore.

• Log in as dev user
• Edit ~.bashrc and add at the end

export EDITOR="vim -v"

export WORKON_HOME=~/envs
source /usr/local/bin/virtualenvwrapper.sh

• Log out then log-in again (to activate virtualenvwrapper)
• Create virtualenv

mkvirtualenv --no-site-packages buildbot

• Install buildbot

easy_install buildbot-slave

• Create the slave

mkdir -p buildbot && cd buildbot
buildslave create-slave slave SERVER_IP:9989 BUILDER_ID BUILDER_PASS

• Edit files in slave/info/ and put host description and maintainer
• Start the slave

cd slave/
buildslave start
