hadoop集群启动脚本和查看多台服务jps脚本

1.集群批量启动hadoop

#!/bin/bash
if [ $# -lt 1 ]
then
  echo "No Args Input..."
  exit;
fi
case $1 in
"start")
      echo "=============启动hadoop集群============"
      echo "-------------启动 hdfs-----------------"
      #尽量写绝对路径
      ssh hadoop01 "/home/software/hadoop-3.1.3/sbin/start-dfs.sh"
      echo "-------------启动 yarn-----------------"
      ssh hadoop02 "/home/software/hadoop-3.1.3/sbin/start-yarn.sh"
      echo "-------------启动 historyserver--------"
      #启动历史服务器
      ssh hadoop01 "/home/software/hadoop-3.1.3/bin/mapred --daemon start historyserver"
;;
"stop")
      echo "=============关闭hadoop集群============"
      #关闭服务器时与启动相反
      echo "-------------关闭 historyserver--------"
      ssh hadoop01 "/home/software/hadoop-3.1.3/bin/mapred --daemon stop historyserver"
      echo "-------------关闭 yarn-----------------"
      ssh hadoop02 "/home/software/hadoop-3.1.3/sbin/stop-yarn.sh"
      echo "-------------关闭 hdfs-----------------"
      ssh hadoop01 "/home/software/hadoop-3.1.3/sbin/stop-dfs.sh"
;;
*)
      echo "Input Args Error..."
;;
esac

2.查看多台服务jps脚本

#!/bin/bash

for host in hadoop01 hadoop02 hadoop03
do
     echo ===========$host==========
     ssh $host  /home/software/jdk1.8.0_321/bin/jps
done
