Screen ./tfs.sh

Screen starts, but after reboot does not want to restart the server


tfs.sh

#!/bin/bash

rm screenlog.*

ulimit -c unlimited

screen -L -S Classic ./tfs;

A bash script doesn't execute itself just like that when rebooting the server.
You might also want to consider giving the full path of TFS in the script.
Now to making a script automatically restarting:

First make a script that automatically restarts tfs, here you can get creative (for example including PIDs, config and ini files, etc) but to keep it simple lets do it like this:

#!/bin/bash
while true; do /path/to/tfs; done

Now to make this automatically execute, we will create a service
To do so, create a file called (for example) TFS in /etc/init.d
touch /etc/init.d/TFS
This file should contain the following code -- Modify the paths, script, user, etc so it fits your server!

#!/bin/sh
### BEGIN INIT INFO
# Provides:          TFS
# Required-Start:    $local_fs $network $named $time $syslog
# Required-Stop:     $local_fs $network $named $time $syslog
# Default-Start:     2 3 4 5
# Default-Stop:      0 1 6
# Description:       foo
### END INIT INFO

SCRIPT="screen -dmS tfs /path/to/your/restart/script"
RUNAS=tfs

PIDFILE=/var/run/TFS.pid
LOGFILE=/var/log/TFS.log

start() {
  if [ -f $PIDFILE ] && kill -0 $(head -1 $PIDFILE); then
    echo 'Service already running' >&2
    return 1
  fi
  echo 'Starting service…' >&2
  local CMD="$SCRIPT > \"$LOGFILE\" & echo \$!"
  su -s "/bin/sh" -c "$CMD" $RUNAS > "$PIDFILE"
  echo 'Service started' >&2
}

stop() {
  if [ ! -f "$PIDFILE" ] || ! kill -0 $(head -1 "$PIDFILE"); then
    echo 'Service not running' >&2
    return 1
  fi
  echo 'Stopping service…' >&2
  kill -15 $(head -1 "$PIDFILE") && rm -f "$PIDFILE"
  kill $(screen -list | grep tfs | cut -d'.' -f1)
  echo 'Service stopped' >&2
}

uninstall() {
  echo -n "Are you really sure you want to uninstall this service? That cannot be undone. [yes|No] "
  local SURE
  read SURE
  if [ "$SURE" = "yes" ]; then
    stop
    rm -f "$PIDFILE"
    echo "Notice: log file is not be removed: '$LOGFILE'" >&2
    update-rc.d -f TFS remove
    rm -fv "$0"
  fi
}

case "$1" in
  start)
    start
    ;;
  stop)
    stop
    ;;
  uninstall)
    uninstall
    ;;
  restart)
    stop
    start
    ;;
  *)
    echo "Usage: $0 {start|stop|restart|uninstall}"
esac

Make sure the user chosen has access to the PID and the LOG file.

Now to enable this you need to do the following:
sudo chmod +x /etc/init.d/TFS sudo update-rc.d TFS defaults sudo update-rc.d TFS enable sudo systemctl daemon-reload sudo service TFS start


A quick FYI: I didn't test it, just wrote it within the last 2 minutes, but it should work, tell me if it doesn't and I'll modify it.
