If you use this script (Kafka server stop. SH) to close the Kafka process in the Kafka/bin directory, you will find that

No Kafka server to stop

View the modification script: VI kafka-server-stop.sh and find that:

16 PIDS=$(ps ax | grep -i 'kafka\.Kafka' | grep java | grep -v grep | awk '{print $1}')
17#PIDS=$(jps -lm | grep -i 'kafka.Kafka' | awk '{print $1}')
18 
19 if [ -z "$PIDS" ]; then
20   echo "No kafka server to stop"
21   exit 1
22 else 
23   kill -s TERM $PIDS
24 fi

At this time, you can change the PIDs = $(PS ax | grep – I ‘Kafka \. Kafka’ | grep Java | grep – V grep | awk ‘{print $1}’) to

PIDS=$(jps -lm | grep -i ‘kafka.Kafka’ | awk ‘{print $1}’)

You can use it to close Kafka successfully

Sometimes when we write the Kafka close script, we call this script to close. If we don’t modify it, the script you write will not close Kafka
