Confluent Control Center UI - not coming up
hi All,
I've installed Confluent Kafka 3.2.2 & am using the following link to start
the services -
http://docs.confluent.io/current/control-center/docs/quickstart.html
I've started the services shown below, however the Contraol Center UI is
not coming up. Any ideas on this ?
screen -ls
> There are screens on:
> 16213.control-center (Detached)
> 16096.connect-distributed (Detached)
> 15961.kafka (Detached)
> 15260.zookeeper (Detached)
> 4 Sockets in /var/run/screen/S-root.
Url i'm trying to access is -> http://<fqdn>:9021/
The control-center.properties file is as shown below ->
cat /tmp/control-center.properties

Re: Confluent Control Center UI - not coming up
Posted by karan alang <ka...@gmail.com>.
Hello all- i was able to fix this by modifying the following entry
confluent.controlcenter.rest.listeners=http://0.0.0.0:9021 ->
confluent.controlcenter.rest.listeners=http://<fqdn>:9021
<http://0.0.0.0:9021/>
