Install OpenHAB2 on emonSD / emonPi

fluppie007 · 29 September 2016 18:31

Hi all,

I tried to install OpenHAB 2 beta 4 on this image. Because of the absence of a openhab2 folder in /var/log OpenHAB 2 doesn’t start. So rpi-rw, sudo mkdir openhab2, sudo chown openhab:openhab openhab2 and openhab 2 works. But after a reboot my openhab2 folder is gone… Any ideas?

Also started a thread here: Trying to install OH 2 beta 4 on OpenEnergyMonitor image - #4 by rlkoshak - Beginners - openHAB Community

This is because on the emonpi /var/log is mounted as a temp RAM partition.

You need to edit ~/emonpi/rc.local_jessieminimal which is symlinked to /etc/rc.local to create the folder you need on startup:

github.com

openenergymonitor/emonpi/blob/master/rc.local_jessieminimal

#!/bin/sh
#
# rc.local

echo" My IP address is":
hostname -I

# WLAN fix on RasPi 3B+ Stretch
rm /var/run/wpa_supplicant/wlan0
ifdown wlan0
sleep 1
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

Once you get openHAB 2 up and running it would be great if you could update us on OpenHAB development. How soon should we all update to openHAB 2? How can we replicate the OpenEnergyMonitor OpenHAB setup on openHab2?

Done, now a small step further

The other trick we do on the emonSD is mount var/lib/openhab onto tmpfs

~/emonpi/fstab is symlinked to /etc/fstab

github.com

openenergymonitor/emonpi/blob/master/fstab#L5

    
      
          tmpfs           /tmp             tmpfs   nodev,nosuid,size=30M,mode=1777 0  0
          tmpfs           /var/tmp         tmpfs   nodev,nosuid,size=1M,mode=1777  0  0

          /dev/mmcblk0p3  /home/pi/data    ext2    defaults,rw,noatime,nodiratime,errors=remount-ro 0 2

It looks like you might need to add an entry to also mount /usr/share/openhab2

I already changed that one to /openhab2

Just tried a empty jessie lite image and installed openhab2, this works fine.
So it only comes from removing openhab 1.8 and/or the read-only filesystem.

glyn.hudson · 1 October 2016 00:43

From the log files this seems to be the main issue. Any idea what this is and how it can be installed?

fluppie007 · 10 October 2016 22:25

Ok, I retried. Took a clean image. How I started:

sudo apt-get update
sudo apt-get remove openhab-runtime
java -version
sudo apt-get install screen mc vim git htop
sudo apt-get install oracle-java8-jdk
sudo echo 'deb http://dl.bintray.com/openhab/apt-repo2 testing main' | sudo tee /etc/apt/sources.list.d/openhab2.list
sudo wget -qO - 'https://bintray.com/user/downloadSubjectPublicKey?username=openhab' | sudo apt-key add -
sudo apt-get update
sudo reboot

sudo nano ~/emonpi/rc.local_jessieminimal
Changed line 11 openhab to openhab2
Changed line 17 /var/log/openhab to /var/log/openhab2
sudo reboot

sudo nano ~/emonpi/fstab
Changed line 5 /var/lib/openhab to /var/lib/openhab2
added underneath line 5 tmpfs           /usr/share/openhab2 tmpfs  nodev,nosuid,size=40M,mode=1777 0  0
sudo apt-get install openhab2-offline
sudo systemctl start openhab2.service
sudo systemctl status openhab2.service
sudo systemctl daemon-reload
sudo systemctl enable openhab2.service
sudo reboot

openHAB2 won’t run, also no log file in /var/log/openhab2

Then again, a sudo reboot and a sudo apt-get upgrade. Same result .

Oh dear, this is not cool.

I can’t see anything useful in the log files. I’m afraid I don’t know the intricacies of how openhab works let alone openhab2 to debug further without better info from the log. Maybe it’s time to ask the openhab forum guys regarding running on R/O FS.

Already a work in progress Trying to install OH 2 beta 4 on OpenEnergyMonitor image - Beginners - openHAB Community

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

glyn.hudson · 26 November 2016 21:08

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.
