如何启动Hbase,以及启动脚本

第一步 先启动hadoop

myhadoop.sh start

在bin目录下vim myhadoop.sh

查看代码

#!/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 demo02 "/opt/module/hadoop-3.1.4/sbin/start-dfs.sh"
        echo " --------------- 启动 yarn ---------------"
        ssh demo03 "/opt/module/hadoop-3.1.4/sbin/start-yarn.sh"
        echo " --------------- 启动 historyserver ---------------"
        ssh demo02 "/opt/module/hadoop-3.1.4/bin/mapred --daemon start historyserver"
;;
"stop")
        echo " =================== 关闭 hadoop集群 ==================="

        echo " --------------- 关闭 historyserver ---------------"
        ssh demo02 "/opt/module/hadoop-3.1.4/bin/mapred --daemon stop historyserver"
        echo " --------------- 关闭 yarn ---------------"
        ssh demo03 "/opt/module/hadoop-3.1.4/sbin/stop-yarn.sh"
        echo " --------------- 关闭 hdfs ---------------"
        ssh demo02 "/opt/module/hadoop-3.1.4/sbin/stop-dfs.sh"
;;
*)
    echo "Input Args Error..."
;;
esac

第二步 启动zookeeper

同样bin目录下vim zk.sh

查看代码

#!/bin/bash 
case $1 in
"start"){
for i in demo02 demo03 demo04
do
echo ---------- zookeeper $i 启动 ------------ 
ssh $i "/opt/module/zookeeper-3.5.7/bin/zkServer.sh start"
done
};;
"stop"){
for i in demo02 demo03 demo04
do
echo ---------- zookeeper $i 停止 ------------ 
ssh $i "/opt/module/zookeeper-3.5.7/bin/zkServer.sh stop"
done
};;
"status"){
for i in demo02 demo03 demo04
do
echo ---------- zookeeper $i 状态 ------------ 
ssh $i "/opt/module/zookeeper-3.5.7/bin/zkServer.sh status"
done
};;
esac

第三步启动hbase

四.查看启动情况

在bin目录下vim jpsall

查看代码

for host in demo02 demo03 demo04
do
        echo =============== $host ===============
        ssh $host jps
done

 

按下i进入输入模式

输入结束后点击esc键，输入:wq保存并退出
