change the port for ambari server

[#1]

when I start configuring My Ambari server, I put the port (3306): 8080, but I realize later that this port is the wrong port, so I restart My set up of My ambari service from scratch (sudo service ambari server setup) but i get this error when I want to start the service:

DB configs consistency check: no errors and warnings were found.
ERROR: Exiting with exit code 1.
REASON: Server not yet listening on http port 8080 after 50 seconds. Exiting.<br>

it seems like the 8080 port still exists.

How can I Force the change?

@yassine sihi,

Ambari will by default run on port 8080. 3306 is default port for mysql . If you still want to use 3306 for ambari (though it is not recommended)

You can add this line in /etc/ambari-server/conf/ambari.properties

client.api.port=3306

Restart ambari server after doing this

ambari-server restart

Also check the logs to find out exact issue, (/var/log/ambari-server/ambari-server.log)

Thanks,

Aditya

If you are planning to change the ambari server port due to the following message then you should not.

.
The following error just indicates that your Ambari Server is taking slightly more than default 50 Seconds time to open port 8080 and hence you see this message.

ERROR: Exiting with exit code 1.
REASON: Server not yet listening on http port 8080 after 50 seconds. Exiting.

You should try the following to fix this:

Edit the "/etc/ambari-server/conf/ambari.properties" and increase the following property value to 120 or 150 seconds.

server.startup.web.timeout=120 

Then restart the ambari-server again.

# ambari-server restart

.

Thank you @Jay Kumar SenSharma . This makes sense and I understand what is causing the error. But i have a bit of an issue in fixing it. I'm still fairly new in Linux, could you help me by specifying the exact commands i need to run in to adjust the 50 to 120. I'm attaching an image showing what i have tried and results thereof. runtime-error.png

Any way we can edit parameters before starting VM? I starting it first time and it is stuck on ‘ connecting ambari agent services’ . Nothing further. It really is annoying and doesn’t allow me further to work.

How can I edit file if I am starting the VM first time and the VM did not start yet. Is there a way I can edit parameter in the file before starting VM?

I am not even able to open VM, so how can I change parameters from 50 sec to 120 sec in the file suggested?

Use vi /etc/ambari-server/conf/ambari.properties , add the entry, then esc, then :, then wq for save and quite or q! for without saving
