Hadoop啟動結束

1. 對hdfs ,yarn,historyserver服務的啟動，結束

#!/bin/bash
​
if [ $# -lt 1 ]
then
    echo "No Args Input..."
    exit;
fi
​
case $1 in
"start")
        echo "=========啟動 Hadoop叢集=========="
​
        echo "---------啟動 hdfs----------"
        ssh master "/opt/module/hadoop-3.1.3/sbin/start-dfs.sh"
        echo "---------啟動 yarn----------"
        ssh slave1 "/opt/module/hadoop-3.1.3/sbin/start-yarn.sh"
        echo "---------啟動 historyserver----------"
        ssh master "/opt/module/hadoop-3.1.3/bin/mapred --daemon starts historyserver
 
"
;;
"stop")
        echo "=========關閉 Hadoop叢集=========="
​
        echo "---------關閉 historyserver----------"
        ssh master "/opt/module/hadoop-3.1.3/bin/mapred --daemon stop historyserver"
        echo "---------關閉 yarn----------"
        ssh slave1 "/opt/module/hadoop-3.1.3/sbin/stop-yarn.sh"
        echo "---------關閉 hdfs----------"
        ssh master "/opt/module/hadoop-3.1.3/sbin/stop-dfs.sh"
;;
*)
    echo "Input Args Error..."
;;
esac
 

2. 各個叢集jps命令檢視服務

#!/bin/bash
​
for host in master slave1 slave2
do
        echo ========== $host ===========
        ssh $host jps
done
