Hadoop 启动停止集群和查看节点服务运行情况的脚本配置

centos7

启动停止集群脚本

在 /home/用户名/bin 中新建文件 myhadoop.sh 作为启动停止集群的脚本文件

内容如下:

#!/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 ---------------" 
        ssh hadoop102 "/opt/module/hadoop-3.1.3/sbin/start-dfs.sh" 
        echo " --------------- 启动 yarn ---------------" 
        ssh hadoop103 "/opt/module/hadoop-3.1.3/sbin/start-yarn.sh" 
        echo " --------------- 启动 historyserver ---------------" 
        ssh hadoop102 "/opt/module/hadoop-3.1.3/bin/mapred --daemon start historyserver" 
;; 
"stop") 
        echo " =================== 关闭 hadoop集群 ===================" 
 
        echo " --------------- 关闭 historyserver ---------------" 
        ssh hadoop102 "/opt/module/hadoop-3.1.3/bin/mapred --daemon stop historyserver" 
        echo " --------------- 关闭 yarn ---------------" 
        ssh hadoop103 "/opt/module/hadoop-3.1.3/sbin/stop-yarn.sh" 
        echo " --------------- 关闭 hdfs ---------------" 
        ssh hadoop102 "/opt/module/hadoop-3.1.3/sbin/stop-dfs.sh" 
;; 
*) 
    echo "Input Args Error..." 
;; 
esac

查看各节点服务运行情况脚本

在 /home/用户名/bin 中新建文件 jpsall 作为查看各节点服务运行情况的脚本文件

内容如下:

#!/bin/bash 
 
for host in hadoop102 hadoop103 hadoop104 
do 
        echo =============== $host =============== 
        ssh $host jps  
done

最后将两个脚本同步到其他节点上

xsync /home/cheetah/bin

需配置xsync转 xsync的配置
