Systemd specify a config file
I have this systemd unit file and my attempt was to convert the existing init.d script to a systemd unit file. I am having trouble declaring the config file that should be used as declared in the init.d script.

Here is the init.d script:
Code:
# The following variables can be overwritten in $DEFAULT
# maximum number of open files
MAX_OPEN_FILES=
# overwrite settings from default file
if [ -f "$DEFAULT" ]; then
      . "$DEFAULT"
fi
# set maximum open files if set
if [ -n "$MAX_OPEN_FILES" ]; then
    ulimit -n $MAX_OPEN_FILES
fi
get_user_shell() {
    local shell=$(getent passwd ${1:-`whoami`} | cut -d: -f7 | sed -e 's/[[:space:]]*$//')
    if [[ $shell == *"/sbin/nologin" ]] || [[ $shell == "/bin/false" ]] || [[ -z "$shell" ]];
    then
      shell="/bin/bash"
    fi
    echo "$shell"
}
super() {
    local shell=$(get_user_shell $USER)
    su - $USER -s $shell -c "PATH=$PATH; PM2_HOME=$PM2_HOME $*"
}
start() {
    echo "Starting $NAME"
    super $PM2 start --only="$PM2_APP_NAME" --env=production $PM2_CONFIG_FILE
}
stop() {
    super $PM2 stop --only="$PM2_APP_NAME" $PM2_CONFIG_FILE
    $PM2 kill
}
restart() {
    echo "Restarting $NAME"
    stop
    start
}
reload() {
    echo "Reloading $NAME"
    super $PM2 reload --only="$PM2_APP_NAME" $PM2_CONFIG_FILE
}
status() {
    echo "Status for $NAME:"
    super $PM2 list
    RETVAL=$?
}
case "$1" in
    start)
        start
        ;;
    stop)
        stop
        ;;
    status)
        status
        ;;
    restart)
        restart
        ;;
    reload)
        reload
        ;;
    force-reload)
        reload
        ;;
    *)
        echo "Usage: {start|stop|status|restart|reload|force-reload}"
        exit 1
        ;;
esac
exit $RETVAL

And here is my attempt so far of the systemd unit file:

Code:
[Unit]
Description=app1
Documentation=https://pm2.keymetrics.io/
After=network.target

[Service]
Type=forking
User=appuser
LimitNOFILE=infinity
LimitNPROC=infinity
LimitCORE=infinity
Environment=PATH=/usr/local/bin:/usr/bin:/bin:/usr/local/games:/usr/games:/usr/bin:/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin
Environment=PM2_HOME=/home/appuser/.pm2
PIDFile=/home/appuser/.pm2/pm2.pid
Restart=on-failure

ExecStart=/home/appuser/products/services/ash/releases/2.10.0/node_modules/pm2/bin/pm2  "-c /home/appuser/products/services/app1/current/ecosystem.config.js"
ExecReload=/home/appuser/products/services/ash/releases/2.10.0/node_modules/pm2/bin/pm2 reload all
ExecStop=/home/appuser/products/services/ash/releases/2.10.0/node_modules/pm2/bin/pm2 kill

[Install]
WantedBy=multi-user.target

So far I cannot get this to work?

SERVICE(8)                                                    System Manager's Manual                                                   SERVICE(8)

NAME

       service - run a System V init script

SYNOPSIS

       service SCRIPT COMMAND [OPTIONS]

       service --status-all

       service --help | -h | --version

DESCRIPTION

       service  runs  a System V init script or systemd unit in as predictable an environment as possible, removing most environment variables and
       with the current working directory set to /.

       The SCRIPT parameter specifies a System V init script, located in /etc/init.d/SCRIPT, or the name of a systemd unit.  The  existence  of  a
       systemd unit of the same name as a script in /etc/init.d will cause the unit to take precedence over the init.d script.  The supported val-
       ues of COMMAND depend on the invoked script. service passes COMMAND  and OPTIONS to the init script unmodified. For systemd  units,  start,
       stop, status, and reload are passed through to their systemctl/initctl equivalents.

       All scripts should support at least the start and stop commands.  As a special case, if COMMAND is --full-restart, the script is run twice,
       first with the stop command, then with the start command.

       service --status-all runs all init scripts, in alphabetical order, with the status command. The status is [ + ] for running services, [ - ]
       for stopped services and [ ? ] for services without a status command.  This option only calls status for sysvinit jobs.

EXIT CODES

       service calls the init script and returns the status returned by it.

FILES

       /etc/init.d
              The directory containing System V init scripts.

       /{lib,run,etc}/systemd/system
              The directories containing systemd units.

ENVIRONMENT

       LANG,  LANGUAGE,  LC_CTYPE, LC_NUMERIC, LC_TIME, LC_COLLATE, LC_MONETARY, LC_MESSAGES, LC_PAPER, LC_NAME, LC_ADDRESS, LC_TELEPHONE, LC_MEA-
       SUREMENT, LC_IDENTIFICATION, LC_ALL, TERM, PATH
              The only environment variables passed to the init scripts.
