利用ssh来实现集群的启动和停止

    1. vi kf.sh
    3. #! /bin/bash
    6. case $1 in
    7. "start"){
    8.  for i in hadoop001 hadoop002 hadoop003
    9.  do
    10.   echo "-------启动 $i kafka----------"
    11.   ssh $i "source /etc/profile; /root/kafka/bin/kafka-server-start.sh -daemon /root/kafka/config/server.properties"
    12.   done
    13. };;
    14. "stop"){
    15.  for i in hadoop001 hadoop002 hadoop003
    16.  do
    17.   echo "------- 停止 $i kafka----------"
    18.   ssh $i "source /etc/profile; /root/kafka/bin/kafka-server-stop.sh stop "
    19.   done
    20. };;
    21. esac
    25. :wq
    1. chmod 777 kf.sh
    2. ./kf.sh start
