Setting up haproxy as a daemon on your ubuntu server

haproxyd.sh

#!/bin/bash

CONFIG=/etc/haproxy/haproxy.cfg
DAEMON=$(which haproxy)

function get_pid() {
  PID=$(ps aux | grep haproxy | grep -v grep | awk '{print $2}')
}

function get_status() {
  get_pid

  if [ -z $PID ]; then
    echo 'not running'
  else
    echo "running with pid: $PID"
  fi
}

case $1 in
  start)
    echo -n 'starting haproxy '
    $DAEMON -f $CONFIG
    get_status
    ;;
  restart)
    echo -n 'restarting haproxy '
    get_pid
    $DAEMON -f $CONFIG -sf $PID
    get_status
    ;;
  stop)
    echo -n 'stopping haproxy '
    get_pid
    kill -9 $PID
    get_status
    ;;
  status)
    echo -n 'haproxy is '
    get_status
    ;;
  *)
    echo "Usage: haproxyd {start|restart|stop|status}" >&2
    exit 1
    ;;
esac

exit 0

Once the script above is available on /etc/init.d do the following (Ubuntu/Debian)

cd /etc/init.d
sudo update-rc.d haproxyd defaults

then you can

$ sudo service haproxyd status
haproxy is running with pid: 4498

root@ipXX:/etc/init.d# ./haproxy status
haproxy is ./haproxy: line 13: [: 9060: binary operator expected
running with pid: 9060
9062
