Thanks for your reply

Actually this is the only error.

Following my config

input {

http {
port => 80
}

beats {
port => 5000

type => syslog

}
file {
path => "/var/log/httpd/*"
start_position => beginning
}

}
output {
elasticsearch {}
stdout {}
}

That port 80 is the likely culprit. Programs can't bind to privileged ports, which are <1024, unless run as root. This is not recommended for Logstash, either. I recommend you get your clients to use an unprivileged port.
