I have a server written in Erlang, compiled with Rebar, and I make a release with Relx. Starts nicely with 

/root/rel/share3/bin/share3 start

The next step is to start when the server boots.

I have tried different approaches, the last one is using the /etc/init.d/skeleton where I changed the following

NAME=share3
DAEMON=/root/rel/share3/bin/share3
DAEMON_ARGS="$1"

After that, I run update-rc.d, but I have not gotten it too work. (Ubuntu 14.04)

The service runs until the machine reboots, and I need to login and start it again.

For Windows, it is really elegant, since it can create the Windows service.

Ubuntu uses upstart as init system, so you could try something like that:

description "Start my awesome service"
start on runlevel [2345]
stop on runlevel [!2345]

respawn
exec /root/rel/share3/bin/share3

You have to place this script in /etc/init/ directory with '.conf' extension like '/etc/init/share3.coinf'. To start it invoke sudo start share3.

At last, I solved it!

I have told to relx to place the result at /home/mattias/rel. The script from relx is /home/mattias/rel/share3/bin/share3

Replace the row

SCRIPT_DIR="$(dirname "$0")"

by (you need to fix the path /home/mattias/rel)

HOME=/home/mattias
export HOME
SCRIPT_DIR="/home/mattias/rel/share3/bin"

Copy the file to /etc/init.d/share3 using

sudo cp ~/rel/share3/bin/share3 /etc/init.d/

Test that it works using

/etc/init.d/share3 start

and 

/etc/init.d/share3 stop

In order to make it start at boot, install sysv-rc-conf

sudo apt-get install sysv-rc-conf

Enable boot at start using

sudo sysv-rc-conf share3 on

and disable 

sudo sysv-rc-conf share3 off

Alternatives are welcome.
