Package Selection

The Easy Way: the installer kickstart file.

The Hard Way:

While installing, select a the GNOME Desktop and then select Custom package development; the following categories were selected:

• Desktop Environments
  • Gnome Desktop Environment
• Applications
  • Editors
  • Test-based internet
    • Add lynx
• Development
  • Development Tools
  • Development Libraries
  • X Software Development
  • GNOME Software Development
  • Legacy Software Development
• Servers
  • Turn all off, except for "Printing Support
• Base System
  • Turn off Dialup Networking
  • Turn on System Tools

Some Sys-prepping

On first boot, CentOS will ask some questions:

• Turn the firewall off (we run our build machines on their own network, behind a firewall)
• Disable SELinux
• Enable NTP

1. Login; install VMwareTools-3.0.1-32039.rpm
2. vmware-config-tools.pl
3. add clock=pit and vdso=no lines to /boot/grub/grub.conf
4. turn on syncTime in VMware config
5. for s in auditd avahi-daemon acpid bluetooth cpuspeed hplip hidd mcstrans pcscd ntpd cups cups-config-daemon mdmonitor openibd smartd pcmcia isdn atd gpm anacron autofs apmd kudzu yum-updated; do chkconfig $s off; done
6. chkconfig vncserver on
7. Copy over cltbld's ssh keys from another tinderbox
8. Edit /etc/mail/sendmail.cf and add mail.build.mozilla.org as the "Smart Relay"
9. rm /etc/sshd/ssh_host_*

Add the following lines to ~/.bash_profile

export CVS_RSH=ssh
export JAVA_HOME=/builds/jdk
export TBOX_CLIENT_CVS_DIR="/builds/tinderbox/mozilla/tools"

Install Sun Java JDK

Note: we should archive this binary somewhere

• Go to http://java.sun.com/javase/downloads/
• Click through to JDK 5.0 Update 10
• Download the "Linux self-extracting file"... not the RPM

d916c24bed9eef7aebc2626115e14a11  jdk-1_5_0_10-linux-i586.bin

• Save to /tools

cd /tools
chmod 0755 ./dist/jdk-1_5_0_10-linux-i586.bin 
./dist/jdk-1_5_0_10-linux-i586.bin 
# type 'yes' to accept the license
ln -s jdk1.5.0_10/ jdk

Version 3

Make directories

 mkdir -p /tools/dist/logs
 mkdir -p /builds/logs

Initial Setup Steps

export PYTHONHOME="/tools/python"
export PATH="/tools/python/bin:$PATH"

Installing Zope Interface

cd /tools/dist/
wget http://www.zope.org/Products/ZopeInterface/3.3.0/zope.interface-3.3.0.tar.gz
tar xfvz zope.interface-3.3.0.tar.gz 
cd zope.interface-3.3.0/
python setup.py install --prefix=/tools/zope-interface-3.3.0
cd /tools; ln -s zope-interface-3.3.0/ zope-interface
export PYTHONPATH="/tools/zope-interface/lib/python2.5/site-packages/:$PYTHONPATH"

Installing Twisted

cd /tools/dist/
wget http://tmrc.mit.edu/mirror/twisted/Twisted/2.4/TwistedCore-2.4.0.tar.bz2
wget http://tmrc.mit.edu/mirror/twisted/Twisted/2.4/Twisted-2.4.0.tar.bz2
tar xfvj TwistedCore-2.4.0.tar.bz2 
tar xfvj Twisted-2.4.0.tar.bz2 
cd TwistedCore-2.4.0
python setup.py install --prefix=/tools/twisted-core-2.4.0
pushd /tools/; ln -s twisted-core-2.4.0/ twisted-core; popd
export PYTHONPATH="/tools/twisted-core/lib/python2.5/site-packages:$PYTHONPATH"
cd /tools/dist/Twisted-2.4.0/
python setup.py install --prefix=/tools/twisted-2.4.0
cd /tools; ln -s twisted-2.4.0 twisted
export PYTHONPATH="/tools/twisted/lib/python2.5/site-packages/:$PYTHONPATH"

Version 4

Installing Mercurial

wget http://www.selenic.com/mercurial/release/mercurial-0.9.5.tar.gz
tar -zvxf mercurial-0.9.5.tar.gz
cd mercurial-0.9.5
export PYTHONHOME="/tools/python"
export PATH="/tools/python/bin:$PATH"
python setup.py install

Installing Scratchbox

As root:

wget http://repository.maemo.org/stable/chinook/maemo-scratchbox-install_4.0.1.sh
chmod a+x ./maemo-scratchbox-install_4.0.sh
./maemo-scratchbox-install_4.0.sh -s /scratchbox
/scratchbox/sbin/sbox_adduser cltbld yes

As cltbld:
Comment out the PYTHONHOME and PATH entries in ~/.bash_profile.

source ~/.bash_profile
wget http://tablets-dev.nokia.com/chinook/maemo-sdk-install_4.0.1.sh
chmod +x maemo-sdk-install_4.0.sh
bash maemo-sdk-install_4.0.sh
/scratchbox/login
wget http://ftp.gnome.org/pub/gnome/sources/libIDL/0.8/libIDL-0.8.9.tar.gz
tar -xzvf libIDL-0.8.9.tar.gz
cd libIDL-0.8.9
./configure --prefix=/usr
make
make install

Remove the comments from the PYTHONHOME and PATH entries in ~/.bash_profile and source it again.

Installing Nagios NRPE Daemon

wget http://dag.wieers.com/rpm/packages/nagios-plugins/nagios-plugins-1.4.9-1.el5.rf.i386.rpm
wget http://dag.wieers.com/rpm/packages/nagios-nrpe/nagios-nrpe-2.5.2-1.el5.rf.i386.rpm
wget http://dag.wieers.com/rpm/packages/nagios-nrpe/nagios-plugins-nrpe-2.5.2-1.el5.rf.i386.rpm
rpm --nodeps -i *.rpm
chkconfig --level 235 nrpe on
# todo: make sure this is right after configs get checked in
cvs co -d nagios mozilla/tools/nagios
mv nagios/nrpe-linux.cfg /etc/nagios/nrpe.cfg

Post-Install Setup

Post-install instructions are written for the latest version (currently, Version 4).
You should have a /builds drive added to the VM before completing this section.

Move Scratchbox

Scratchbox takes up a non-trivial amount of space and should be moved to a different partition.

1. Boot into single user mode (append 'init=/bin/sh' to the kernel params from grub).
2. mount -o remount,rw /
3. mv /scratchbox /builds
4. ln -s /builds/scratchbox /scratchbox
5. mount -o remount,ro /
6. Reboot the VM.

Installing BuildBot

Because our Buildbot code changes fairly regularly we don't keep a copy of it on the VM.

export PATH="/tools/twisted/bin:/tools/twisted-core/bin:$PATH"
cd /tools
cvs -d:pserver:anonymous@cvs-mirror.mozilla.org:/cvsroot co -d buildbot-076 -r BUILDBOT_0_7_6_BRANCH mozilla/tools/buildbot
cd /tools/buildbot-trunk
export PYTHONPATH=.:$PYTHONPATH
python setup.py install --prefix=/tools/buildbot-076
cd /tools/dist
cvs -d:pserver:anonymous@cvs-mirror.mozilla.org:/cvsroot co -d botrunner mozilla/tools/botrunner.py
cp botrunner/botrunner.py /tools/buildbot-trunk/bin/
rm -rf botrunner/
cd /tools; ln -s buildbot-trunk buildbot

Path Setup

Add the appropriate paths to the cltbld user's .bash_profile

export PYTHONPATH="/tools/buildbot/lib/python2.5/site-packages:/tools/twisted/lib/python2.5/site-packages:/tools/twisted-corelib/python2.5/site-packages/:/tools/zope-interface/lib/python2.5/site-packages/"
export PATH="/opt/local/bin:/tools/buildbot/bin:/tools/twisted/bin:/tools/twisted-core/bin:$PYTHONHOME/bin:$PATH"

To build mozilla

The mozconfig for building mozilla should contain the following settings:

CC=/tools/gcc/bin/gcc
CXX=/tools/gcc/bin/g++
