The live server is a virtual server running FreeBSD 7.2-RELEASE #0, it has 4Gb of RAM (found via ​this script) though only 1Gb is for our use.

There are ​munin stats for the server.

The migration from the ​old live server to the new one is being tracked on ticket #97.

Backups

The gaia script for backing up the Mysql databases is /root/sbin/mysql_backup_daily.sh and it contains:

#!/bin/sh
BACKUP=/var/backups/mysql_backup.`date +%a`.sql.gz
/usr/local/bin/mysqldump -h localhost -u root -pXXX --all-databases | /usr/bin/gzip -c > $BACKUP

# backup to the development server, kiwi.webarch.net see ~/.ssh/config
scp $BACKUP kiwi:new-live-data/var/backups/
# file system backup
rsync -qaz /web/ kiwi:new-live-data/web/

And /root/.ssh/config contains:

Host kiwi
  User live
  Hostname kiwi.webarch.net

The Mysql backups are written to /home/live/new-live-data/var/backups and the /web/ directory containing all the sites is rsynced to home/live/new-live-data/web/ on kiwi.webarch.net

Cron

The following crontab for the transnetwww user ensures that tasks like the sending of the newsletter are carried out:

crontab -e -u transnetwww
  # m h  dom mon dow   command
  */5 * * * * /usr/local/sbin/ab -v 1 -n 1 http://transitionnetwork-live.gaiahost.coop/cron.php >/dev/null 2>&1 

You can manually access the cron script to run it via ​https://transitionnetwork-live.gaiahost.coop/cron.php using a username / password, the http version is restricted to access from the local host only, see the configuration in /usr/local/etc/apache22/extra/httpd-ssl.conf and /usr/local/etc/apache22/Includes/vhost-transnetwww.conf

p5-libwww

Installed for perl's LWP::UserAgent to fix this error in /var/log/munin/munin-node.log:

 Can't locate object method "new" via package "LWP::UserAgent" at /usr/local/etc/munin/plugins/apache_volume line 130.

cd /usr/ports/www/p5-libwww
make config
  ===> No options to configure
make install clean

munin-node

Munin was installed in order that server info could be ​generated on the dev server.

cd /usr/ports/sysutils/munin-node
make config
  ===> No options to configure
make install clean
  Would you like me to set up log rotation [y]? y
  
  ********************************************************************
  Unless this file already existed, a sample configuration file
  has been placed in /usr/local/etc/munin/munin-node.conf.
  
  Please edit it according to your needs.
  
  ********************************************************************
  
  The Munin client will *not* be started automatically. To allow it
  to start, put this line in /etc/rc.conf:
  
  munin_node_enable="YES"
  
  Then, it will be started on the next boot. If this line is already
  present, the client will be started now.  Otherwise, edit
  /etc/rc.conf and execute this command:
  
      /usr/local/etc/rc.d/munin-node start
  ********************************************************************

Then /usr/local/etc/munin/munin-node.conf was edited and the following was added:

allow ^81\.95\.52\.78$

And then the following was added to /etc/rc.conf:

munin_node_enable="YES"

And then it was started:

/usr/local/etc/rc.d/munin-node start

By default there was no apache plugins configured, so this was done:

cd /usr/local/etc/munin/plugins
ln -s /usr/local/share/munin/plugins/apache_accesses
ln -s /usr/local/share/munin/plugins/apache_processes
ln -s /usr/local/share/munin/plugins/apache_volume 
ln -s /usr/local/share/munin/plugins/df
ln -s /usr/local/share/munin/plugins/df_inode
ln -s /usr/local/share/munin/plugins/load
ln -s /usr/local/share/munin/plugins/memory
ln -s /usr/local/share/munin/plugins/multimemory
ln -s /usr/local/share/munin/plugins/mysql_bytes

ln -s /usr/local/share/munin/plugins/netstat
ln -s /usr/local/share/munin/plugins/ntp_offset
ln -s /usr/local/share/munin/plugins/open_files
ln -s /usr/local/share/munin/plugins/processes
ln -s /usr/local/share/munin/plugins/sendmail_mailqueue
ln -s /usr/local/share/munin/plugins/sendmail_mailstats
ln -s /usr/local/share/munin/plugins/sendmail_mailtraffic
ln -s /usr/local/share/munin/plugins/swap
ln -s /usr/local/share/munin/plugins/vmstat

This error in /var/log/munin/munin-node.log

2010/07/30-11:46:26 [74194] Error output from sendmail_mailstats:
2010/07/30-11:46:26 [74194]     mailstats: /var/log/sendmail.st: Permission denied

Was fixed by adding the user and group for sendmail in /usr/local/etc/munin/plugin-conf.d/plugins.conf:

[sendmail*]
user root
group wheel
env.mspqueue /var/spool/clientmqueue
env.mailstats /usr/sbin/mailstats

The Mysql user 'munin' was carried over from the old live server, where it had been created using this command as the Mysql root user:

CREATE USER 'munin'@'localhost' IDENTIFIED BY '********';
GRANT USAGE ON * . * TO 'munin'@'localhost' IDENTIFIED BY '********' WITH MAX_QUERIES_PER_HOUR 0 MAX_CONNECTIONS_PER_HOUR 0 MAX_UPDATES_PER_HOUR 0 MAX_USER_CONNECTIONS 0 ;

And a a /root/.my.cnf file was created:

[client]
user = munin
password = ********
host = localhost

And the Mysql configuration in /usr/local/etc/munin/plugin-conf.d/plugins.conf was changed to:

[mysql*]
user root
group wheel
env.mysqlopts --defaults-extra-file=/root/.my.cnf
env.mysqladmin /usr/local/bin/mysqladmin
env.mysqlshow /usr/local/bin/mysqlshow

The following apache configuration was carried across from the old live server, in the default VirtualHost in /usr/local/etc/apache22/httpd.conf:

<Location /server-status>
    SetHandler server-status
    Order deny,allow
    Deny from all
    Allow from transitiontowns.gaiahost.coop localhost 127.0.0.1 67.217.100.68 67.217.100.83 
</Location>
 
ExtendedStatus On

And this was tested using wget:

wget http://127.0.0.1:80/server-status?auto -O server-status.txt

And munin-run:

munin-run apache_accesses
  accesses80.value 266
munin-run apache_processes
  busy80.value 2
  idle80.value 8
  free80.value 246
munin-run apache_volume
  volume80.value 342016

The p5-libwww was installed so munin could access the server-status and the following was added to /usr/local/etc/munin/plugin-conf.d/plugins.conf:

[apache_*]
user root
group wheel
env.url   http://127.0.0.1:%d/server-status?auto
env.ports 80 

The following apache config changes were also made, in /usr/local/etc/apache22/extra/httpd-info.conf and /usr/local/etc/apache22/httpd.conf

<Location /server-status>
    SetHandler server-status
    Order deny,allow
    Deny from all
    Allow from .gaiahost.coop localhost 127.0.0.1 67.217.100.68 67.217.100.83
</Location>

The old, hacked, multimemory munin plugin (attached to this page) was copied from the old live server to /usr/local/etc/munin/plugins/multimemory.bak and a ​newer version which supports !FreeBSD by default was downloaded:

cd /usr/local/share/munin/plugins
wget http://exchange.munin-monitoring.org/plugins/multimemory/version/1/download -O multimemory
chmod 755 multimemory
cd /usr/local/etc/munin/plugins
ln -s /usr/local/share/munin/plugins/multimemory

And the following was added to /usr/local/etc/munin/plugin-conf.d/plugins.conf:

[multimemory]
user root
group wheel
env.os freebsd
env.names httpd mysqld fcgi sendmail

The ​apache_activity plugin was installed:

cd /usr/local/share/munin/plugins
wget "http://exchange.munin-monitoring.org/plugins/apache_activity/version/1/download" -O apache_activity
chown munin:munin apache_activity 
chmod 755 apache_activity 
cd /usr/local/etc/munin/plugins/
ln -s /usr/local/share/munin/plugins/apache_activity

pecl-uploadprogress

This message in the Drupal admin interface indicated that PECL uploadprogress needed to be installed:

Your server is capable of displaying file upload progress through APC, but it is not enabled. Add apc.rfc1867 = 1 to your php.ini configuration. Alternatively, it is recommended to use PECL uploadprogress, which supports more than one simultaneous upload.

So:

cd /usr/ports/devel/pecl-uploadprogress
make config
  ===> No options to configure
  ****************************************************************************
  
  The following line has been added to your /usr/local/etc/php/extensions.ini
  configuration file to automatically load the installed extension:
  
  extension=uploadprogress.so
  
  ****************************************************************************

phpMyAdmin

phpMyAdmin is available at ​https://transitionnetwork-today.gaiahost.coop/phpmyadmin/

This is in /usr/local/www/phpMyAdmin211 (rather than /usr/local/www/phpMyAdmin as it was on the old live server) but the config file was at /usr/local/www/phpMyAdmin together with the .htpasswd file so the following sym links were created:

cd /usr/local/www/phpMyAdmin211
ln -s ../phpMyAdmin/config.inc.php
ln -s ../phpMyAdmin/.htpasswd 

One line needed changing in /usr/local/www/phpMyAdmin/config.inc.php:

/* $cfg['Servers'][$i]['host'] = 'db.transitionnetwork.gaiahost.coop'; */
$cfg['Servers'][$i]['host'] = 'localhost';

And apache was restarted.
