Penguin

penguin.webarch.net is a 3GB RAM Xen Debian virtual server, it replaced NewLiveServer and DevelopmentServer for running all non-Drupal sites, and went live in early January 2013. Drupal sites from the old servers were migrated to PuffinServer.

The install and initial configuration of this server was tracked on ticket:470.

This server was upgraded from Squeeze to Wheezy on ticket:535 in December 2013.

Console Access

There is a Xen shell available for console access, see wiki:XenShell.

Munin Stats

There are munin stats for the server available here

Munin was installed on penguin via ticket:483#comment:35 and the dynamic graph generation and zooming was sorted out on ticket:641 and the APC plugin was installed on ticket:535#comment:55.

APC Stats and PHP info

There are a few scripts in ​https://penguin.transitionnetwork.org/info/ which use the same username and password as this Trac site:

See ticket:645 for APC tuning.

Updates

All systems updates are recorded on ticket:218.

There is a script in /usr/local/bin called a-up which can be used to update the system via aptitude, the advantage of using this script is that it writes things that are changed to the /root/Changelog and the time spent doing the updates can then be reported via ticket:218, see AptitudeUpdateScript for a copy of a-up and the logchange script it uses to update the Changelog.

Due some packages from dotdeb and backports being used, see ticket:470#comment:6 and ticket:470#comment:41 for some notes on this -- the pinning setup could do with some work, but this is non-urgent, the work-around is to manually upgrade some packages, eg: 

a-up
  About to upgrade munin-node/squeeze-backports munin-plugins-extra/squeeze-backports
  No packages will be installed, upgraded, or removed.
aptitude install munin-node/squeeze-backports munin-plugins-extra/squeeze-backports

The main documentation page for Trac is wiki:TransitionTrac

This trac site is running using trac from debian backports and it is using nginx as a reverse proxy to tracd, to start and stop the server: 

sudo -i
su - tracd -s /bin/bash
cd /web/tech.transitionnetwork.org/bin
./tracd-stop
./tracd-startticket/550#comment:5

Trac is set to start after a reboot via cronjob, see ticket:470#comment:30.
