My Home Server

My Apple Time-Capsule just died, the disk of my AppleTV is starting to make weird noises, my time-lapse recorder needs more storage and cpu-power, and i haven't been creating anything new for too long now :) Guess it's time for a new project...

• QNAP TNS-459Pro+
• 2x Western Digital Caviar Green 2TB, model WD20EARS
• 1x OCZ Onyx SATA-II 30GB SSD Disk

Basic configuration

• Install Optware IPKG from the admin web interface
• Update ipkg: ipkg update
• Install vim as a texteditor: ipkg install vim
• Install Coreutils: ipkg install coreutils

Power management

The disks won't spin down, because system files keep writing to the /share/MD0_DATA/.locks dir. Move the locks dir to the SSD disk:

• /etc/init.d/services.sh stop
• cp -rp /share/MD0_DATA/.locks /share/HDC_DATA/.locks
• mv /share/MD0_DATA/.locks /share/MD0_DATA/.locks_old
• ln -s ../HDC_DATA/.locks /share/MD0_DATA/.locks
• /etc/init.d/services.sh start

Transmission

i installed a Bittorrent downloader on the NAS: (Instructions from http://wiki.qnap.com/wiki/Transmission)

• Install transmission: ipkg install transmission
• It is not advised to run a BitTorrent client as root. Therefore you should create a new user named transmission: adduser -DH transmission
• Add startup script:

mkdir /share/MD0_DATA/System
mkdir /share/MD0_DATA/System/transmission
vi /share/MD0_DATA/System/transmission/transmission_start.sh

#!/bin/sh
#
# start script for transmission/clutch
#
# jorg@bosman.tv - 29 january 2011

TORRENTFOLDER=/share/MD0_DATA/Multimedia/Movies
TRANSMISSION_BIN=/opt/bin/transmission-daemon
TRANSMISSION_HOME=/opt/etc/transmission
TRANSMISSION_USER=transmission
TRANSMISSION_PORT=6888

REMOTE_USER=<username>
REMOTE_PASS=<password>

echo -n "Starting Transmission Daemon..."
su $TRANSMISSION_USER -c "EVENT_NOEPOLL=0 $TRANSMISSION_BIN --blocklist --auth --username $REMOTE_USER --password $REMOTE_PASS --config-dir $TRANSMISSION_HOME --download-dir $TORRENTFOLDER"

#Wait a while till the daemon has started...
sleep 20

#Set a few settings
transmission-remote -n $REMOTE_USER:$REMOTE_PASS --portmap --port $TRANSMISSION_PORT --pex --encryption-preferred

chmod +x /share/MD0_DATA/System/transmission/transmission_start.sh

After a reboot, this script still needs to be started manually. Need to fix that later.

Timelapse

Script to fetch a snapshot from the webcam, every minute, during working hours:

mkdir /share/MD0_DATA/System/timelapse
vi /share/MD0_DATA/System/timelapse/fetch_image.sh

Nagios

• Install some extra dependencies

ipkg install gcc make perl libgd

• Create a user "nagios" via the web interface
• Download and extract nagios-3.3.1.tar.gz

./configure --prefix=/share/nagios --with-nagios-group=everyone
make all

• Comment out these lines, since they break the installation:

vi html/Makefile

• Change these:

for file in includes/rss/*; \
do $(INSTALL) -m 664 $(INSTALL_OPTS) $$file $(DESTDIR)$(HTMLDIR)/includes/rss; done
for file in includes/rss/extlib/*; \
do $(INSTALL) -m 664 $(INSTALL_OPTS) $$file $(DESTDIR)$(HTMLDIR)/includes/rss/extlib; done

Into:

chmod 775 /share/nagios/share/includes/rss
for file in includes/rss/*; \
do $(INSTALL) -m 664 $(INSTALL_OPTS) $$file $(DESTDIR)$(HTMLDIR)/includes/rss; done
chmod 775 /share/nagios/share/includes/rss/extlib
for file in includes/rss/extlib/*; \
do $(INSTALL) -m 664 $(INSTALL_OPTS) $$file $(DESTDIR)$(HTMLDIR)/includes/rss/extlib; done

• Install nagios:

make install
make install-commandmode

• Remove the '-b' from the 'install -b' lines, since that option isn't available:

vi Makefile
make install-config

• Copy startup script and remove the "su" from it:

cp ~/src/nagios/daemon-init ~/bin/daemon
chmod +x ~/bin/daemon
vi ~/bin/daemon

#su - $NagiosUser -c "touch $NagiosVarDir/nagios.log $NagiosRetentionFile"
touch $NagiosVarDir/nagios.log $NagiosRetentionFile

• Make the scripts accessible:

ln -s ~/share/cgi-bin ../sbin

pnp4nagios

• Install some extra dependencies

ipkg install rrdtool grep diffutils sudo

• Download and extract pnp4nagios-0.6.14.tar.gz

./configure --prefix=/share/nagios/pnp4nagios --with-nagios-group=everyone --with-base-url=/nagios/pnp4nagios --with-httpd-conf=/share/nagios/pnp4nagios/etc
make all

• Add this line to /usr/local/apache/conf/apache.conf

Include /share/nagios/pnp4nagios/etc/httpd.conf

• Setup sudo

vi /opt/etc/sudoers.d/nagios
  nagios ALL=(ALL) NOPASSWD: ALL
chmod 440 /opt/etc/sudoers.d/nagios

• Add a root useraccount after the original admin username. (sudo admin remains the default root account)

vi /etc/passwd 
  root:x:0:0:administrators:/share/homes/admin:/bin/sh
