quince.webarch.net

This is a debian Xen virtual server with 1GB ram, 32GB HDD, single partition, 4 processors and one IP address, 81.95.52.88.

Munin starts for the server are available on the webarchitects monitoring server and on the transition network development server.

The live site is being set up at http://live.quince.webarch.net/ and the notes about the old live server are here: LiveServer The move to quince.webarch.net is being sorted out on ticket:147

Mediawiki

The Mediawiki site at http://wiki.transitionnetwork.org/ will be running running on quince.webarch.net after the server switch, ticket:147, it is also available at http://wiki.quince.webarch.net/

There is also a wiki:DevelopmentServer#Mediawiki version of this site at http://wiki.dev.transitionnetwork.org/ -- when upgrading Mediawiki please first test the upgrade on the dev server first.

backup2kiwi

To backup the Mysql database and the files for the web sites to the wiki:DevelopmentServer run the /usr/local/bin/backup2kiwi script, it puts the files in /home/live/quince on kiwi.webarch.net and these files are used by the scripts on kiwi to update the Drupal and Mediwiki sites with the latest data from the live sites.

Mysql Backup

A MySQL Backup script from http://worldcommunitypress.com/opensource/mysql-backup is installed in /usr/local/bin and it's set to create backups in /var/backups/mysql/

It needed the libmime-lite-perl debian package to be installed.

To run it:

/usr/local/bin/mysql-backup

These lines have been changed from the original at http://worldcommunitypress.com/assets/files/opensource/utilities/mysql_backup.txt :

$admin_email_to              = 'chris@webarchitects.co.uk';
$admin_email_from            = 'root@quince.webarch.net';
$cnf_file                    = '/root/.my.cnf';
$site_name                   = 'quince.webarch.net';
$mysql_backup_dir            = '/var/backups/mysql';

Backupninja

Backupninja has been installed and set up -- it's set to backup files to another server in the same rack and then this backups up the data to a server in another colo. The main configuration file is /etc/backupninja.conf and the files containing the list of things to be backed up are in /etc/backup.d/. 60 days worth of backups are saved. It is set to backup MySQL and the following directories:

include = /var/spool/cron/crontabs
include = /var/backups
include = /etc
include = /root
include = /home
include = /usr/local/*bin
include = /var/lib/dpkg/status*
include = /web
exclude = /home/*/.gnupg
exclude = /home/*/.local/share/Trash
exclude = /home/*/.Trash
exclude = /home/*/.thumbnails
exclude = /home/*/.beagle
exclude = /home/*/.aMule
exclude = /home/*/gtk-gnutella-downloads

php

See https://live.quince.webarch.net/info/ for the php info, the php.ini file is /etc/php5/apache2/php.ini

PECL Uploadprogress was installed as suggested here: http://www.joergfelser.at/content/howto-install-pecl-uploadprogress-debian-50-lenny

aptitude install php5-dev
pecl install uploadprogress

And this was added to the php.ini file:

extension=uploadprogress.so

The, default php.ini files which had these changes:

expose_php = Off
memory_limit = 256M
extension=uploadprogress.so

Was moved to php.ini.dist.tweaked and then /usr/share/doc/php5-common/examples/php.ini-recommended was copied to /etc/php5/apache2/php.ini and a new /etc/php5/apache2/conf.d/uploadprogress.ini file was created with this in it:

extension=uploadprogress.so

And /etc/php5/apache2/php.ini was edited and these things were changed:

expose_php = Off
memory_limit = 256M      ; Maximum amount of memory a script may consume (128MB)
error_log = syslog
post_max_size = 12M
upload_max_filesize = 12M
display_errors = On
default_charset = "utf-8"
mysql.default_socket = /var/run/mysqld/mysqld.sock
mysql.default_port = 3306
session.save_path = "N;/var/lib/php5"

phpmyadmin

This is available here: https://live.quince.webarch.net/phpmyadmin/

munin

In addition to the plugins available by default these were installed:

TODO

  1. Sort out drupal errors:
warning: array_merge() [function.array-merge]: Argument #2 is not an array in /web/transitionnetwork.org/www/includes/theme.inc on line 930.
warning: call_user_func_array() [function.call-user-func-array]: First argument is expected to be a valid callback, 'nodereference_autocomplete_access' was given in /web/transitionnetwork.org/www/includes/menu.inc on line 452.
  1. Optimise, what php accelerator should we use? Tweak MySQL defaults.
  1. Cron
  1. Consider switching to http://www.dotdeb.org/ packages for php and mysql -- this should solve the GD problem...

Setup Notes

Live site, directory and svn checkup:

mkdir -p /web/transitionnetwork.org/
cd /web/transitionnetwork.org/
svn co https://svn.webarch.net/transition/code/trunk
mv trunk www
cd /web/transitionnetwork.org/www/sites
mkdir cache
chown www-data:www-data cache
mkdir workspaces.transitionnetwork.org
rsync -av kiwi:/home/live/new-live-data/web/transitionnetwork.org/www/sites/workspaces.transitionnetwork.org/ workspaces.transitionnetwork.org/
chown -R www-data:www-data workspaces.transitionnetwork.org/files/
cd /web/transitionnetwork.org/www/sites/default
rsync -av kiwi:/home/live/new-live-data/web/transitionnetwork.org/www/sites/default/files/ files/
chown -R www-data:www-data files

Databases were imported using a script, /usr/local/bin/mysql-update-from-gaia the two settings.php files were edited to suite.

There was a problem with missing modules:

Warning: require_once(./sites/all/modules/cacherouter/cacherouter.inc) [function.require-once]: failed to open stream: No such file or directory in /web/transitionnetwork.org/www/includes/bootstrap.inc on line 1009

Fatal error: require_once() [function.require]: Failed opening required './sites/all/modules/cacherouter/cacherouter.inc' (include_path='.:/usr/share/php:/usr/share/pear') in /web/transitionnetwork.org/www/includes/bootstrap.inc on line 1009

This modules isn't in svn any more: https://svn.webarch.net/transition/code/trunk/sites/all/modules/cacherouter

So it was copied over manually:

mkdir /web/transitionnetwork.org/www/sites/all/modules/cacherouter/
rsync -av kiwi:/home/live/new-live-data/web/transitionnetwork.org/www/sites/all/modules/cacherouter/ /web/transitionnetwork.org/www/sites/all/modules/cacherouter/

The following Drupal errors:

# warning: call_user_func_array() [function.call-user-func-array]: First argument is expected to be a valid callback, 'ctools_export_ui_task_access' was given in /web/transitionnetwork.org/www/includes/menu.inc on line 452.
