Install OpenHAB2 on emonSD / emonPi

glyn.hudson · 12 October 2016 07:04

Mmm good conversation on that thread. I’m away this week but when I’m home I will try and install open hab 2 myself. Would be good to get install procedure written up to work with our r/o image.

Have you tried added in a line to rc.local to restart openhab2 after creating the log directory?

E.g

github.com

openenergymonitor/emonpi/blob/master/rc.local_jessieminimal#L22

    
      
          ifup wlan0
          
          
# Will only run if /var/log is mounted in tmpfs
          if ( mount | grep "on /var/log "| grep -q "^tmpfs " )
          then
            for i in "redis" "apache2" "mysql" "openhab" "logrotate" "mosquitto" "supervisor" "emonhub" "emoncms"; do mkdir /var/log/"$i"; done
            for i in "emoncms.log" "mysql.log" "mqtt_input.log" "redis/redis-server.log" "service-runner.log" "mysql/error.log" "apache2/error.log" "supervisor/supervisord.log" "ntp_update.log"; do touch /var/log/"$i"; done
            for i in "emoncms.log" "mysql.log" "mqtt_input.log" "redis/redis-server.log" "service-runner.log" "mysql/error.log" "apache2/error.log" "supervisor/supervisord.log" "ntp_update.log"; do ""chmod 666"" /var/log/"$i"; done
            chown -R root:adm /var/log/apache2
            chown -R redis:redis /var/log/redis
            chown -R mysql:adm /var/log/mysql
            chown -R openhab:openhab /var/log/openhab
            chown -R pi:pi /var/log/logrotate
            chown -R mosquitto:mosquitto /var/log/mosquitto
            chown -R dataplicity:dataplicity /var/log/supervisor;
            chown -R emonhub:emonhub /var/log/emonhub
            chown -R pi:pi /var/log/emoncms
            
            touch /home/pi/data/emonpiupdate.log
            ln -s /home/pi/data/emonpiupdate.log /var/log/emoncms/emonpiupdate.log

This is my effort so far once openhab2 is installed via deb:
> mount -t tmpfs tmpfs /var/lib/openhab2/cache

mount -t tmpfs tmpfs /var/lib/openhab2/mapdb
mount -t tmpfs tmpfs /var/lib/openhab2/tmp
mount -t tmpfs tmpfs /var/lib/openhab2/log
ln -s /var/lib/openhab2/tmp/port /var/lib/openhab2/port
ln -s /var/lib/openhab2/tmp/lock /var/lib/openhab2/lock
rm -rf /var/lib/openhab2/persistence && ln -s /mnt/rwdata/openhab2/persistence /var/lib/openhab2/persistence

Did it work?!

mattwire · 27 November 2016 21:27

Sorry! Yes it works. Just wanted to add to the thread in case it helps, I’ve got it running fine on a Pi with the above commands. /mnt/rwdata is a writeable usb stick here (there’s quite a lot of persistence data which could probably be stored in a ram disk if you don’t need to store it permanently). It may help to have mapdb on writeable storage because it takes quite a long time to start up openhab when mapdb database needs to be recreated (and it will store any config created via UI rather than stored in config files in /etc/openhab2).

glyn.hudson · 28 November 2016 10:17

Nice work

I’ll add a link to this thread from the OpenEnergyMonitor OpenHAB git repo

mattwire · 12 December 2016 22:13

There’s been a few changes with openhab2, not least the change to jsondb (replacing mapdb) for saving configuration through the UI. /mnt/rwdata is a read/write usb key. Any config I wish to save is moved to /etc/openhab2 so I can manage it easily.
Below are the steps I’m currently using:

mount -t tmpfs tmpfs /var/lib/openhab2/cache
mount -t tmpfs tmpfs /var/lib/openhab2/tmp
mount -t tmpfs tmpfs /var/lib/openhab2/log
rm /var/lib/openhab2/port && ln -s /var/lib/openhab2/tmp/port /var/lib/openhab2/port
rm -rf /var/lib/openhab2/lock && ln -s /var/lib/openhab2/tmp/lock /var/lib/openhab2/lock
rm -rf /var/lib/openhab2/persistence && ln -s /mnt/rwdata/openhab2/persistence /var/lib/openhab2/persistence
mv /var/lib/openhab2/etc /etc/openhab2/etc
ln -s /etc/openhab2/etc /var/lib/openhab2/etc
mv /var/lib/openhab2/jsondb /etc/openhab2/jsondb
ln -s /etc/openhab2/jsondb /var/lib/openhab2/jsondb

Quick update on this to autoconfigure this:

Create file /usr/share/openhab2/start_pre.sh:

#!/bin/sh
test -d /var/lib/openhab2/cache || mkdir /var/lib/openhab2/cache
mountpoint -q /var/lib/openhab2/cache || mount -t tmpfs tmpfs /var/lib/openhab2/cache
test -d /var/lib/openhab2/tmp || mkdir /var/lib/openhab2/tmp
mountpoint -q /var/lib/openhab2/tmp || mount -t tmpfs tmpfs /var/lib/openhab2/tmp
test -d /var/lib/openhab2/log || mkdir /var/lib/openhab2/log
mountpoint -q /var/lib/openhab2/log || mount -t tmpfs tmpfs /var/lib/openhab2/log

Modify /usr/lib/systemd/system/openhab2.service:

[Unit]
Description=openHAB 2 - empowering the smart home
Documentation=http://docs.openhab.org
Documentation=https://community.openhab.org
Wants=network-online.target
After=network-online.target

[Service]
EnvironmentFile=/etc/default/openhab2
User=openhab
Group=openhab
WorkingDirectory=/usr/share/openhab2
PermissionsStartOnly=true
ExecStartPre=/usr/share/openhab2/start_pre.sh
ExecStart=/usr/share/openhab2/start.sh server
ExecStop=/usr/share/openhab2/runtime/bin/stop
# Shutdown delay in seconds, before process is tried to be killed with KILL (if configured)
TimeoutStopSec=120
Restart=on-failure

[Install]
WantedBy=multi-user.target

(Note: The PermissionsStartOnly=true is important as the start_pre script needs to run as root).

You still need to run the commands on initial setup:

rm /var/lib/openhab2/port && ln -s /var/lib/openhab2/tmp/port /var/lib/openhab2/port
rm -rf /var/lib/openhab2/lock && ln -s /var/lib/openhab2/tmp/lock /var/lib/openhab2/lock
rm -rf /var/lib/openhab2/persistence && ln -s /mnt/rwdata/openhab2/persistence /var/lib/openhab2/persistence
mv /var/lib/openhab2/etc /etc/openhab2/etc
ln -s /etc/openhab2/etc /var/lib/openhab2/etc
mv /var/lib/openhab2/jsondb /etc/openhab2/jsondb
ln -s /etc/openhab2/jsondb /var/lib/openhab2/jsondb

but don’t need the mount commands as they are taken care of in start_pre.sh each run.

Hi Matthew,

I tried your steps on a clean emonSD image (the latest nov16 release) and removed OH1.8 before installing OH2 (stable branch) and OH2-addons.

I’m also struggling with the same issue. I think it could be that OH2 requires some contents in /var/lib/openhab2. I need to look into this further.

mattwire · 27 February 2017 16:12

What is the content of your /usr/lib/systemd/system/openhab2.service and /usr/share/openhab2/start_pre.sh files?

It’s the start_pre.sh script that’s failing according to those logs which means openhab won’t try and start. Make sure PermissionsStartOnly=true is set in openhab2.service as the start_pre.sh script must run as root. Check that the start_pre.sh script will run by itself.

Any idea why the start_pre.sh script isn’t “green” ??

mattwire · 27 February 2017 21:53

It needs to be executable:
chmod +x start_pre.sh

The new log file:

The file system is in Read Only (RO) mode. If you need to make changes,
use the command 'rpi-rw' to put the file system in Read Write (RW) mode.
Use 'rpi-ro' to return to RO mode. The /home/pi/data directory is always in RW m                                                                                                   ode.

Good, progress. Now check your logfile for openhab2 at /var/log/openhab2/openhab.log. There’s probably an error there that’s causing openhab to shutdown. Also run journalctl -xn that might give a clue

fluppie007 · 27 February 2017 22:09

Lol there is no log file :

pi@emonpi(rw):~$ journalctl -xn
No journal files were found.
pi@emonpi(rw):~$ cd /var/log
pi@emonpi(rw):log$ ls

Anything at /var/lib/openhab2/log?

fluppie007 · 27 February 2017 22:19

Empty too… Maybe I did something wrong? You applied these steps on the emonSD image?

mattwire · 27 February 2017 22:29

I have done, yes. Though I find that openhab2 can be a little temperamental if it’s not got everything where it likes it… How did you install openhab2 and which version?

If you installed via the apt repository can you try (I assume you don’t have any openhab configuration you need to keep?):

apt-get --purge remove openhab2
rm -rf /etc/openhab2
rm -rf /var/lib/openhab2

Make sure openhab is not running:

ps -ef | grep "karaf"
ps -ef | grep "openhab"

should return no results

Then try reinstalling openhab2 and configure as above.
Start openhab:

systemctl start openhab2

Hopefully that’ll work…

fluppie007 · 27 February 2017 22:36

I removed openhab-runtime from the image and then I installed OH2 according to: openHAB 2 on Linux - openHAB 2 - Empowering the Smart Home

wget -qO - 'https://bintray.com/user/downloadSubjectPublicKey?username=openhab' | sudo apt-key add -
echo 'deb http://dl.bintray.com/openhab/apt-repo2 stable main' | sudo tee /etc/apt/sources.list.d/openhab2.list

sudo apt-get update
sudo apt-get install openhab2
sudo apt-get install openhab2-addons

sudo systemctl start openhab2.service
sudo systemctl status openhab2.service
  
sudo systemctl daemon-reload
sudo systemctl enable openhab2.service

I’ll try your instructions right away.
