Init.d start-up script

Note, this script doesn't support automatic respawn of process in case of abnormal exit (for example, due to app crash). We recommend using alternative methods which support respawn:

  • Upstart for RedHat/Centos 6.x
  • SystemD for RedHat/Centos 7.x

Create startup script miarec in directory /etc/init.d

vi /etc/init.d/miarec

Make this script executable:

chmod +x /etc/init.d/miarec

Add it to autostart during boot:

chkconfig --add miarec
chkconfig miarec on
