I update the logstash verion from 2.4.0 to 5.4.0 using a tar file but when I start the logstash using ./bin/logstash -f conf.d/logstash.conf command . I got an error

Eep. It looks like there's something funky going on with your config/logstash.yml; can you paste what you've got?

5.4.0 is still pretty far back; if you can't upgrade to Logstash 6, you'll likely have better luck running the latest possible 5.x (which is currently 5.6.10)

Actually problem is with logstash.yml. I closed all parameters that I opened in logstash.yml. After I start it start working.
