RT ticket tracking system Alpine Linux 2.2.0 Howto

Note: Use a computer with at least 512MB of RAM.
Note: This guide will get a basic rt4 setup working that will allow inbound emails to create/update issues.

add edge/main and edge/testing repos to /etc/apk/repositories
apk add lighttpd fcgi postgresql rt4 php php-cli php-common postfix postfix-pcre
Edit lighttpd.conf and enable fastcgi
/etc/init.d/lighttpd start
ln -s /usr/share/rt4/html /var/www/localhost/htdocs/rt4
/etc/init.d/postgresql setup
/etc/init.d/postgresql start
su - postgres
createuser -P

cp /etc/rt4/RT_Config.pm /etc/rt4/RT_SiteConfig.pm
chmod 644 /etc/rt4/RT_SiteConfig.pm
/etc/rt4/RT_SiteConfig.pm change to use Pg instead of mysql
/usr/sbin/rt-setup-database --action init
rt-server
Test and make sure that you can access rt using the built-in webserver first.
Tools -> Configuration -> Queues -> Create... Give it a name like 'support', which you'll use in the next sections (including the email address)
Add to /etc/postfix/main.cf:

virtual_alias_maps = regexp:/etc/postfix/rt4-aliases, transport_maps = regexp:/etc/postfix/rt4-transport

Create /etc/postfix/rt4-aliases:

/^(.*)@.*$/ $1

Create /etc/postfix/rt4-transport:

/^support.*$/ rt4-support:

Add to /etc/postfix/master.cf:

rt4-support unix - n n - - pipe flags=DORhu user=postgres argv=/usr/bin/rt-mailgate --queue support --action correspond --url http://localhost/

Idea is to set up Nagios as an SNMP trap receiver, especially for HP Procurve switch alerts
Source: http://xavier.dusart.free.fr/joomla/index.php/en/nagios/47-traps-snmp-dans-nagios

Add packages:

nagios

nagios-web

lighttpd

net-snmp

perl

snmptt (available from edge/testing)

Create file /etc/snmp/snmptrapd.conf, and populate:

traphandle default /usr/sbin/snmptt

disableAuthorization yes

donotlogtraps  yes

Edit /etc/conf.d/snmptrapd:

OPTIONS="-On -Lsd -p /var/run/snmptrapd.pid"

Start snmptrapd using init script.
Edit /etc/snmptt.ini and insert contents found at source link.

To be continued once my testing is complete :). With the config done as above, snmp traps will simply be logged to syslog since they're all unknown to snmptrapd.
