How to solve the issue of Kafka automatically shutting down after starting up?

If Kafka shuts down automatically after starting, it could be due to a few reasons and can be resolved by:

1. Port is occupied: please check if the port used by Kafka is being used by another process, you can use the command netstat -tlnp to check the port occupation status. If the port is occupied, you can modify the port in the Kafka configuration file to another port that is not occupied.
2. Insufficient Memory: Kafka requires a certain amount of memory resources to operate properly. If the server’s memory is insufficient, Kafka may start and immediately shut down. This issue can be resolved by increasing the server’s memory or reducing Kafka’s memory configuration.
3. Configuration error: Please check if the Kafka configuration file is correct, especially if the settings in the server.properties file are set correctly. You can refer to Kafka’s official documentation for configuration.
4. Data directory permission issue: Kafka will store data in the specified directory, which is by default /tmp/kafka-logs. Make sure that this directory has sufficient permissions for Kafka to use.
5. Error messages in logs: Check the log files during Kafka startup, usually located in the /logs directory, search for error messages, and resolve them accordingly.

If the methods mentioned above fail to resolve the issue, you can also try reinstalling Kafka to ensure a proper installation process. If the problem persists, you can refer to Kafka’s official documentation or seek help from the Kafka community.
