Servers

Bugzilla Project maintains several servers to run services needed by the project. Some of these are also used by other projects. Bugzilla Project also utilizes various services that are hosted and maintained by Mozilla.

Bugzilla uses CentOS 5 and Red Hat Enterprise Linux (RHEL) 6 servers that are updated to latest minor releases. Current versions are CentOS 5.10 and RHEL 6.5 (Dec 2013).

Mozilla-hosted ESX

  • VMware ESX platform is maintained by Mozilla in the SCL3 colo.

landfill.bugzilla.org

A virtual CentOS 5 server for shared development environment including development Bugzilla installations.

  • Slave DNS for internal zones.
    • All zones are transferred from master DNS infra.bugzilla.org.
    • Please read master DNS description for other configuration details.

windows.bugzilla.org

A virtual server for testing Windows support. Currently unused.

oracle.bugzilla.org

A virtual server for testing Oracle database support. Currently unused.

bugzilla1.community.scl3.mozilla.com AKA cg-bugs01.bugzilla.lan

A RHEL 6 server that runs automated tests for the Bugzilla software.

  • Uses Tinderbox Client v2.01 to run Perl, Docs, QA, Xt and checksetup Bugzilla test suites.
  • Reports test results to the Tinderbox Server maintained by Mozilla. See tinderbox.mozilla.org/Bugzilla/ for latest results.
  • Current activity of the tests can be viewed by attaching to a screen session running under the tinderbox user. There's two sessions, one for QA tests (named qa) and one for all the other tests (named tbox). Use commands screen -r qa or screen -r tbox to attach.
  • Selenium Server v2.5.0, Test::WWW::Selenium Perl module v1.24 and Firefox v6.0.2 are used by the QA tests. Be careful when updating these so that the trees won't burn unnecessarily.
  • Selenium Server is manually installed to the /usr/local/share/selenium-server/ directory. Scripts to start it and to list related processes are in the /usr/local/bin/ directory.
  • Firefox is manually installed to the ~/firefox-6.0.2/ directory of the tinderbox user. The system has Firefox v3.6.x but it's not used for the tests.
  • The perl-Test-WWW-Selenium package is installed/updated from Repoforge (previously known as RPMforge) but is excluded from normal yum updates so it needs to be manually updated (use yum update --disableexcludes=rpmforge perl-Test-WWW-Selenium command) when needed.
  • Any local RPM building should be done when logged in as the user build because that user has the correct RPM build environment configured.

bugzilla2.community.scl3.mozilla.com AKA cg-bugs02.bugzilla.lan

A RHEL 6 server that hosts virtual servers.

  • Uses qemu+kvm virtualization to run up to four (4) RHEL 6 virtual servers.

updates.bugzilla.org

A virtual RHEL 6 server for Bugzilla update services.

  • Delivers Bugzilla version information XML to Bugzilla instances all around the world.
  • Uses nginx as a high performance web server.

bots.bugzilla.org

A virtual RHEL 6 server for IRC bots.

  • Infobot word that connects to various channels in irc.mozilla.org IRC server to deliver factoids.
  • Supybot bugbot that keeps an eye on bugs in various major Bugzilla installations.
    • Receives bugmail from various major Bugzilla installations.
    • Maintains a presence on Freenode, Mozilla and GNOME IRC networks on various channels for announcing bug changes and fetching bug information.

infra.bugzilla.org

A virtual RHEL 6 server for basic infrastructure services.

  • Master DNS for internal zones.
    • Zones include bugzilla.lan, 99.168.192.in-addr.arpa, 122.168.192.in-addr.arpa and bugzilla.jp that are accessible only internally by Bugzilla servers. Additionally, includes standard zones required to be in every DNS.
    • Forwards all external name requests to mradm01.mozilla.org, ns2.globalnetoptex.com or ns2.lax01.mzima.net but will fall back to resolving requests directly by itself if none of the forwarders are available.

bugzilla3.scl3.mozilla.com AKA cg-bugs03.bugzilla.lan

A RHEL 6 server for hosting automated Bugzilla demo installations.

  • Hosts demo.bugzilla.org service.
  • Uses local MySQL database for the installations.
  • Replicates bugs_tip from landfill that is used as a basis for the new installations.
