kafka集群分发其它两台：
xsync.sh kafka
kafka环境变量分发：
scp /etc/profile.d/my_env.sh root@hadoop103:/etc/profile.d/
scp /etc/profile.d/my_env.sh root@hadoop104:/etc/profile.d/
kafa启动
#! /bin/bash
case $1 in
"start"){
for i in hadoop102 hadoop103 hadoop104
do
echo " --------启动 $i Kafka-------"
ssh $i "/opt/module/kafka/bin/kafka-server-start.sh -daemon /opt/module/kafka/config/server.properties"
done
};;
"stop"){
for i in hadoop102 hadoop103 hadoop104
do
echo " --------停止 $i Kafka-------"
ssh $i "/opt/module/kafka/bin/kafka-server-stop.sh stop"
done
};;
esac
记住先关kafka再关zookeeper
