Automatically start dwagent service while system boot in linux

edit

I need to start Dwagent service while System Boot in feodra 22(Before User login).

manually start the service using /etc/init.d/dwagent start

What i did before:

1. add a script to /root/.bash_profile

    /etc/init.d/dwagent start
   

   After Reboot, its not working for me.

2. add to chkconfig

   follow this link to add dwagent to chkconfig

    chkconfig --add dwagent
   
    chkconfig --list
   

   chkconfig --list Note:

   This output shows SysV services only and does not include native systemd services. SysV configuration data might be overridden by native systemd configuration. If you want to list systemd services use 'systemctl list-unit-files'. To see services enabled on particular target use 'systemctl list-dependencies [target]'.

   dwagent 0:off 1:off 2:on 3:on 4:on 5:on 6:off

its add to chkconfig list after the i reboot the system, now also not working for me.

1. Use the init scripts

   Add my myscript.sh script to the folder named /etc/init.d.

   myscript.sh:

   #!bin/bash
   
   /etc/init.d/dwagent start
   

   After editing and saving, i give file executable permission.

   chmod +x /etc/init.d/myscript.sh.
   

   Reboot system and But.its not start the dwagent service for me,
