Can't run ONOS on my local machine

[kavya kota]

Hello,

I'm following the developer quick start (https://wiki.onosproject.org/display/ONOS/Developer+Quick+Start#). Up until building onos, everything is fine "Build completed successfully", but when I tried to run onos using the "bazel run onos-local -- clean debug" command, the process stuck, there is no "STATE READY" message. I attached some of the error messages.

Appreciate any help, thanks!

Hi kavya,

It seems that you have an app that use that tcp port, maybe you have another istance of atomix/onos that running there. Could you try to run ps -aux | grep onos  thanks to this command you can see if there are other onos istances tha running in the machine and kill them.

Hello Davide,

Thanks for the reply, unfortunately, killing the onos process (using sudo kill -9 pid) didn't work for me. The onos process persistently occurs even after I killed it (as you can see in the attached screenshot).

I also tried restarting my machine, but still onos can't be run with the same error happened.

Any other solution?

Regards

Hi Kavya,

Probably you have a service/application that use that tcp port.

You should be sure that this port is available to atomix/onos

Hi,

Davide explained it properly, you need to kill the application listening on port 9876. You can sudo netstat -tlpn | grep :9876. It will give the process name and pid that you need to call. The error  you saw in ONOS is because there was already a process listening there (ONOS docker? tar? any other process I guess can also be listening in that port).

Hope it works.

Cheers,

Hello,

Thanks for replying, I tried your suggestion, and as you can see in the screenshots, I killed the application that was listening to port 9876 (pid: 53535) then I made sure that nothing was listening to the port. But still I got the same error when running the command bazel run onos-local -- clean debug. Any other solution?

Thanks in advance.

Hi,

I would stop any process listening on that port again and remove the ~/onos folder (if you have nothing critical there). Restart the VM. I would try to clone again ONOS. Make sure to checkout a recent version like 2.6.0. Make sure you are not running any tar.gz or Docker ONOS container. Be sure you did not create any config file that autostarts an ONOS service on restart.

Then build it again locally and run. Let's see if error disappears. 

Alternatively, you could run ONOS as a Docker container if running a locally built app does not work. Let's see if that fails. Also restart

Cheers,
