Configuring init.d service in the absence of systemd

In distributions where systemd is unavailable (e.g., older Linux versions like CentOS 6), service management is handled through init.d scripts. This article describes how to create and configure init.d-compatible services for running Smart Beat and Smart Beat Manager.

Installing Smart Beat and Smart Beat Manager​

  1. Preparing the Environment

Create system users (smartbeat and sbm) and directories for the executable files (/app/smartBeat and /app/smartBeatManager).

Copy the .elf files of Smart Beat and Smart Beat Manager to the appropriate directories and make them executable:

chmod +x /app/smartBeat/smartbeat.elf
chmod +x /app/smartBeatManager/sbm.elf
  1. Initial Launch

Run the applications with root privileges for initial initialization:

/app/smartBeat/smartbeat.elf install --ignore-systemd
/app/smartBeatManager/sbm.elf install --ignore-systemd

This will create the necessary working folders and configuration files.

After generation, assign ownership of the directories to the respective users:

chown -Rf smartbeat:smartbeat /app/smartBeat/
chown -Rf sbm:sbm /app/smartBeatManager/

Creating init.d Services​

In systems without systemd support, service processes are managed via init.d scripts. Below are working init.d scripts for Smart Beat and Smart Beat Manager.

Script for Smart Beat​

Service for smartBeat:

### BEGIN INIT INFO

# Required-Stop:     $remote_fs $network

# Description:       Service to run the Smart Beat application
### END INIT INFO

test -x $DAEMON || exit 0

case "$1" in
  start)
    echo "Starting $DESC..."
    su -c "cd $WORKDIR && nohup $DAEMON $DAEMON_OPTS > /dev/null 2>&1 &" $USER
    echo "$DESC started."

    pkill -f "$DAEMON $DAEMON_OPTS"
    echo "$DESC stopped."
    ;;
  restart)
    echo "Restarting $DESC..."
    $0 stop
    sleep 10
    $0 start
    ;;
  status)
    if pgrep -f "$DAEMON $DAEMON_OPTS" > /dev/null; then
      echo "$DESC is running."
    else
      echo "$DESC is not running."
    fi
    ;;
  *)
    echo "Usage: /etc/init.d/$NAME {start|stop|restart|status}"
    exit 1
    ;;
esac

exit 0

Script for Smart Beat Manager​

Service for smartBeatManager:

### BEGIN INIT INFO
# Provides:          smartbeatmanager
# Required-Start:    $remote_fs $network
# Required-Stop:     $remote_fs $network
# Default-Start:     2 3 4 5
# Default-Stop:
# Short-Description: Smart Beat Manager Service
# Description:       Service to run the Smart Beat Manager application
### END INIT INFO

NAME="sbm"
DESC="Smart Beat Manager Service"
DAEMON="/app/smartBeatManager/sbm.elf"
DAEMON_OPTS="run"
PIDFILE="/var/run/$NAME.pid"
USER="sbm"
WORKDIR="/app/smartBeatManager"

test -x $DAEMON || exit 0

case "$1" in
  start)
    echo "Starting $DESC..."
    su -c "cd $WORKDIR && nohup $DAEMON > /dev/null 2>&1 &" $USER
    echo "$DESC started."
    ;;
  stop)
    echo "Stopping $DESC..."
    pkill -f "$DAEMON"
    echo "$DESC stopped."
    ;;
  restart)
    echo "Restarting $DESC..."
    $0 stop
    sleep 1
    $0 start
    ;;
  status)
    if pgrep -f "$DAEMON" > /dev/null; then
      echo "$DESC is running."
    else
      echo "$DESC is not running."
    fi
    ;;
  *)
    echo "Usage: /etc/init.d/$NAME {start|stop|restart|status}"
    exit 1
    ;;
esac

exit 0

Now services can be managed using standard commands:

service smartBeat.service start

# The following commands are also available:
# service smartBeat.service stop
# service smartBeat.service status
# service smartBeat.service restart

Similarly - for smartBeatManager.service.
