I need to create ratchet service on my dedicated server (CentOS 6). I have successfully created this service on local CentOS 7. The problem is that the server has got old version of CentOS and I need to create a service there.

I have taken the following steps to create a service in CentOS 7:

Created a file named ratchet.service in /etc/systemd/system/ and put the following in it:

[Unit]

Description=Ratchet Service

After=network.target



[Service]

Type=simple

ExecStart=/usr/bin/php -f /path/to/ratchet/server$

Restart=on-abort



[Install]

WantedBy=multi-user.target

To start:

service ratchet start

Can anyone please advise how can this be achieved in CentOS 6?

UPDATE:
What i am trying to achieve is to run Ratchet Service written in php.I want to run this service on Centos 6 so that it can run persistently on my server.
I need to execute server file script (named above as /path/to/ratchet/server.php).

I am following this tutorial and code :
https://github.com/amirsanni/Video-Call-App

I'll provide the basic service script but anyone is invited to improve my answer.

This is for CentOS 6.10

The service scripts are placed in this directory: /etc/rc.d/init.d

There's a template provided by the system, open the file with your editor of choice (example vi): vi /usr/share/doc/initscripts-*/sysvinitfiles

Here's a simple example of my kafka script:

#!/bin/bash

#/etc/rc.d/init.d/kafka



# Source function library.

. /etc/init.d/functions





start() {

        echo -n "Starting kafka... "

        nohup /home/kafka/kafka/bin/kafka-server-start.sh /home/kafka/kafka/config/server.properties &

        touch /var/lock/subsys/kafka

        return 0

}



stop() {

        echo -n "Shutting down kafka... "

        nohup /home/kafka/kafka/bin/kafka-server-stop.sh &

        rm -f /var/lock/subsys/kafka

        return 0

}



case "$1" in

    start)

        start

        ;;

    stop)

        stop

        ;;

    status)

        ;;

    restart)

        stop

        start

        ;;

    reload)

        ;;

    *)

        echo "Usage: kafka {start|stop|status|reload|restart}"

 exit 1

        ;;

esac

exit $?

Based on this kafka example, this file should be saved as /etc/rc.d/init.d/kafka

I run it by typing: service kafka start

You can write the init script logic in vi editor & save in /etc/init.d path, as shown below:-

vi /etc/init.d/ratchet

write your start/stop/restart logic here

Once done, you can start the service

service ratchet start

or

/etc/init.d/rachet start
