Unable to open Control Center

[girish meena]

Hi,

I am not able to open control center UI on 2 installation. I follow these steps to install confluent and using 1 month free subscription key for CC.

https://docs.confluent.io/current/installation/installing_cp/deb-ubuntu.html#systemd-ubuntu-debian-install

I am getting unable to connect message when opening localhost:9021

As I am new to this Please let me know if needed anything from my side.

Thanks In Advance for any help!!

Did you check the logs from Confluent Control Center for errors?

I run the command sudo journalctl -f -u confluent-control-center

Hi All,

I can now see the control center UI. right now, I have 2 installation of Confluent Platform one at local machine VM, another is on VM on Network

I successfully see the UI on local VM after changing the control-center.service file, it was referring the confluent-control-center-production.properties file.though I changed confluent-control-center.properties and thought that by default it is used.

On second installation, I could not able to run the CC UI through systemctl command, I checked in log and it shows that it keeps getting restarted again and again. So, I started it manually using command /usr/bin/control-center-start /etc/confluent-control-center.properties & disown.

Thanks @Robin, you pointed me in right direction.
