PicApport running fine in a FreeNAS jail, but not as a service

[Gegele1]

I got PicApport, a nice self-hosted private photo and video opensource server with gallery and photo management, to run in a FreeNAS Jail, but could not get it to run as a service.

Installation of PicApport, in a freenas jail (11.3):

1 - Created a jail in my favorite pool (say "MyPool" for the exemple)
using Freenas wizard and igb1 interface / vnet0 avec BPF (Berkeley Packet Filter)
In Jail properties, checked that mount_fdescfs is checked.

2 - Mounted the volume containing photos from the wizard

3 - Installed pkg (system will guide when I simply entered pkg at command line)

4 - Installed, using pkg install, whatever packages I am used to work with ; sudo, nano, etc …

5 - Installed java14 :
Pkg install openjdk14 (or any other version that you want after version 8)

At the end of iava installation, the script sends a message to mount the volumes fdesc and proc,

Either manually (I could not get it to work):
sudo mount -t fdescfs fdesc /dev/fd
sudo mount -t procfs proc /proc

Or through fstab file:
starting from host shell edited /mnt/"MyPool"/iocage/jails/PicApport/fstab added the following at the end:
fdesc /mnt/"MyPool"/iocage/jails/PicApport/root/dev/fd fdescfs rw 0 0
proc /mnt/"MyPool"/iocage/jails/PicApport/root/proc procfs rw 0 0

6 - Installed PicApport from the jail shell:
6.1 - Created directories:
mkdir /opt
mkdir /opt/picapport
mkdir /opt/picapport/.picapport

6.2 - copied the files from PicApport site (https://www.picapport.de)
copied picapport-headless.jar to /opt/picapport/.
copied picapport.properties to /opt/picapport/.picapport/.
No need to copy picapport and StartPicApport.sh files, they won't work with FreeBSD.

6.3 Made rc.d script file /etc/rc.d/picapport with the following contents:
(this is an adaptation to freeBSD of the picapport provided startup files, and from an exemple of java daemon startup script for unify in FreeBSD)

#!/bin/sh

picapport_prestart()
{
if [ ! -e /var/run/picapport ] ; then
install -d -o picapport -g picapport /var/run/picapport;
fi
}

run_rc_command "$1"

Saved it as /etc/rc.d/picapport

7 - Edited /etc/rc.conf adding

# Enable PicApport
Picapport_enable="YES"

8 - Edited /opt/picapport/.picapport/picapport.properties to adapt the line robot.root.0.path= to my photos library directory,

9 - Restarted the jail,

10 - Enjoyed the application !


The application is running, can find it in /var/run.

I can connect to my server using most web browsers (did not find a browser of Apple IOS9.3 to work). The pictures in the gallery may seem to show a little more noise than the originals, depending of the web browser I am using. PicApport seems to have many options and features that I have not yet explored.

The application seems to run fine with this, but I expected to have picapport behave as a service, and in spite of all my attempts, i could not get picapport to answer to 'service picapport status'. I am far from being knowledgeable in FreeBSD scripting and if someone could help me fix this issue, that would close the subject of a completely clean PicApport installation in a FreeBSD jail.

For your rc.d script, you need to have a picapport_start() and a picapport_stop() routine. Something like this:

Code:

#!/bin/sh

        fi

Hi Samuel,
I thank you for your fast answer. I am sure you are right, but when I copy the code to /etc/rc.d/picapport, after restarting the jail, I still have the PicApport application running fine, but when I issue a 'service picapport status', i receive the following answer:

env: /etc/rc.d/picapport: No such file or directory

I think this might be due to inadequate command:

: ${picapport_chdir:=/opt/picapport/.picapport}

I am not sure what this is for: the .jar program is in /opt/picapport while the program properties are in /opt/picapport/.picapport

It is very late here, and I shall try and fix this tomorrow morning.

Thank you again,
