Upgrading Control Center¶
Upgrading from version 3.0.0¶
NOTE: the upgrade process will delete historical stream monitoring data older than the configured retention time (
confluent.monitoring.interceptor.topic.retention.ms) for the stream monitoring topic.
Stop the Control Center process
Copy the 3.0.0 configuration file$ sudo cp /etc/confluent-control-center/control-center.properties /etc/confluent-control-center/control-center-3.0.0.properties
Upgrade to version 3.0.1$ # Via yum $ sudo yum update confluent-control-center $ # Via apt-get $ sudo apt-get update && apt-get upgrade confluent-control-center
Reset the application (deleting internal state)$ # Use the same properties file you used to launch Control Center $ /usr/bin/control-center-3_0_0-reset /etc/confluent-control-center/control-center-3.0.0.properties
Edit the Control Center properties file. Some configuration property names have changed
1. This isn’t strictly necessary but a good precaution in case any step of the reset failed.
Start Control Center$ /usr/bin/control-center-start /etc/confluent-control-center/control-center.properties
