Kibana4 to listen on Port 80 instead of Port 5601

Edit file {kibana-directory}/config/kibana.yml. Find this line:

port: 5601

and change it to:

port: 80

You need to set capabilities CAP_NET_BIND_SERVICE to bind non root process to a privileged port (<1024)

to make kibana listen on port 80 :

1- edit kibana port in /etc/kibana/kibana.yml

server.port : "80"

2- run the following commands :

sudo setcap cap_net_bind_service=+epi /usr/share/kibana/bin/kibanasudo setcap cap_net_bind_service=+epi /usr/share/kibana/bin/kibana-pluginsudo setcap cap_net_bind_service=+epi /usr/share/kibana/bin/kibana-keystoresudo setcap cap_net_bind_service=+epi /usr/share/kibana/node/bin/node

Setting the port 80 in config file will trigger the following errorkibana[11777]: FATAL Error: listen EACCES: permission denied 0.0.0.0:80due to the fact that kibana service by default executes under the user kibana

You can change the user to root, but this will trigger the following warningkibana[11639]: Kibana should not be run as root. Use --allow-root to continue.

So running kibana service under root user is something not recommended. Better make a port forwarding rule, or a HTTP redirect if you have a web server.
