Start Service on Boot Ubuntu

In this example we are going to learn how to start tomcat on system startup.

1. Add following shell script to /etc/init.d/tomcat

### BEGIN INIT INFO
# Provides:        solr
# Required-Start:  $network
# Required-Stop:   $network
# Default-Start:   2 3 4 5
# Default-Stop:    0 1 6
# Short-Description: Start/Stop solr server
### END INIT INFO

PATH=/sbin:/bin:/usr/sbin:/usr/bin

start() {
   sh  /opt/apache-tomcat-8.0.36/bin/startup.sh
}

stop() {
    sh /opt/apache-tomcat-8.0.36/bin/shutdown.sh
}

case $1 in
  start|stop) $1;;
  restart) stop; start;;
  *) echo "Run as $0 <start|stop|restart>"; exit 1;;
esac


2. Make the script executable

  

 sudo chmod +x /etc/init.d/tomcat

3. List all the service and find your service in the list
   

service --status-all

 The services that have a [+] - (service name) will start on boot.  The ones with [-] - (service name) will not start on boot.

4. Starting a server

service tomcat start

5. Add service to automatic startup
  

sudo update-rc.d tomcat defaults

5. Remove service from automatic startup

sudo update-rc.d -f tomcat remove

 rm /etc/rc*/*tomcat

6. Ubuntu startup log can be found in following location

/var/log/boot.log
