Nifi doesn't listen on port 8080 in some Linux distributions

[Chris Teoh <ch...@gmail.com>]

Hey all,

I've noticed trying to run Nifi on Centos 7 and a docker Ubuntu image
doesn't seem to launch the server.

Is there something I'm missing here?

Kind regards
Chris

If the firewall isn't the problem, there could be a resource conflict for
the port.  On CentOS,

netstat -ant

will show the listening and connected ports.  If something shows on
LocalAddress=0.0.0.0:8080 or <host_ip>:8080 and State=LISTEN, then the port
is already in use by another process.  You find the process with

netstat -pant

which will include a column with information about the process that is
using the port.

(Ubuntu syntax should be similar, but check the manpage if these parameters
don't work as expected.)

Chris,

Also please take a look in the 'logs/nifi-app.log' and
'logs/nifi-bootstrap.log' to see if there is anything interesting
there.

Thanks
Joe

Check your firewalls. If you have a running instance and can't open the
graph, the firewall is the first place to start. If there is a conflict on
the port, you will see it in the app log. It will say something like "Port
XXXX already in use" but if it starts and seems to be running fine, then it
is probably your firewalls.
