ReleaseEngineering/How To/Setup a buildbot master

These instructions are probably incomplete, but should serve as a good starting point for setting up a new buildbot master. If you find something missing or inaccurate, please update!

• Create a new directory for your master, e.g. /builds/buildbot/mymaster

• Create a virtual environment for your master

virtualenv --distribute --no-site-packages -p /tools/python-2.6.5/bin/python /builds/buildbot/mymaster

• Install required packages

pip install simplejson
pip install mysql-python
pip install Twisted==10.1.0
pip install sqlalchemy
pip install argparse
pip install pycrypto
pip install pyasn1
pip install mysql-python
pip install pyopenssl==0.10
pip install http://hg.mozilla.org/users/clegnitto_mozilla.com/mozillapulse/archive/tip.tar.bz2
hg clone http://hg.mozilla.org/build/buildbot
(cd buildbot/master; $PYTHON setup.py develop install)
(cd buildbot/slave; $PYTHON setup.py develop install)
hg clone -b production-0.8 http://hg.mozilla.org/build/buildbotcustom
hg clone -b production http://hg.mozilla.org/build/buildbot-configs
hg clone http://hg.mozilla.org/build/tools

• Add Makefile

PWD=$(shell pwd)
BUILDBOT=$(PWD)/bin/buildbot
HG=/tools/python-2.6.5/bin/hg
export PYTHONDONTWRITEBYTECODE=1
export PYTHONPATH=/builds/buildbot/mymaster/tools/lib/python

start:
        cd master && $(BUILDBOT) start $$PWD
stop:
        cd master && $(BUILDBOT) stop $$PWD
restart:
        cd master && $(BUILDBOT) restart $$PWD
reconfig:
        cd master && $(BUILDBOT) reconfig $$PWD
checkconfig:
        cd master && $(BUILDBOT) checkconfig
update:
        (cd buildbotcustom && $(HG) pull && $(HG) update -C)
        (cd buildbot-configs && $(HG) pull && $(HG) update -C)
        (cd tools && $(HG) pull && $(HG) update -C)
version:
        $(BUILDBOT) --version

• Setup master

mkdir master
cd master
ln -s ../buildbot-configs/config.py .
ln -s ../buildbot-configs/production_config.py localconfig.py
etc. --catlee too tired to fill this in right now. add symlinks and run make checkconfig until it works!

• Setup cron jobs

# In /home/cltbld/.mymaster_update_from_files.conf
[DEFAULT]
database = mysql://buildbot:password@tm-b01-master01.mozilla.org/buildbot
master = http://fqdn:8011
name = My master!

# In /etc/cron.d/mymaster
MAILTO=release@mozilla.com

• Update production-masters.json in tools if appropriate

• SSH Keys
  • Copy production ssh keys (for ffxbld and trybld) to ~/.ssh.
  • Make sure you can ssh to ffxbld@dm-pvtbuild01.mozilla.org and ffxbld@stage.mozilla.org

• Make sure NTP is running!
