如果在kafka/bin目录下用这个脚本（kafka-server-stop.sh）关闭kafka进程会发现

报错说：No kafka server to stop

查看改脚本：vi kafka-server-stop.sh 发现：

PIDS=$(ps ax | grep -i 'kafka\.Kafka' | grep java | grep -v grep | awk '{print $1}')
 #PIDS=$(jps -lm | grep -i 'kafka.Kafka' | awk '{print $1}')

if [ -z "$PIDS" ]; then
  echo "No kafka server to stop"
  exit 1
else 
  kill -s TERM $PIDS
fi

此时可以把PIDS=$(ps ax | grep -i 'kafka\.Kafka' | grep java | grep -v grep | awk '{print $1}')这行代码修改为

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

即可成功使用它关闭kafka啦！

我们有时候写kafka关闭脚本的时候也会调用此脚本关闭，如果不修改，也会导致你写的脚本关闭不了kafka！！
