This is as simple upstart job which we wrote for starting our application but I am unable to find any good solution to make it for systemD… If I may create a simple Start and Post Exec command base file, It just gave me errors and nothing work…
I have only hurdles with those basic values as from start to setgid root? how can we write it in SystemD service?
description "evercam_media"
start on filesystem or runlevel [2345]
stop on runlevel [!2345]
limit nofile 1000000 1000000
respawn
chdir /
setuid root
setgid root
env HOME=/home/root
env LANG=en_US.UTF-8
env LANGUAGE=en_US:en
env LS_ALL=en_US.UTF-8
env ERL_MAX_PORTS=10240
exec watch -n1 '/usr/local/bin/run_evercam_media.sh'
post-stop exec sudo pkill beam
Any help will be wonderful, i have been struggling so long on this

This should be a good starting point:
[Unit]
Description=evercam media
After=network-online.target
[Service]
Restart=on-failure
User=root
Group=root
Environment=HOME=/home/root LANG=en_US.UTF-8 LANGUAGE=en_US:en LS_ALL=en_US.UTF-8 ERL_MAX_PORTS=10240
WorkingDirectory=/
ExecStart=/usr/bin/watch -n1 '/usr/local/bin/run_evercam_media.sh'
ExecStopPost=/bin/pkill beam
LimitNOFILE=1000000
[Install]
WantedBy=multi-user.target
The main difference is that systemd requires absolute paths. I noticed that the service is running as root. I would recommend looking into having it run as a regular user unless absolutely necessary :)
