linux-shell脚本收集

创建同步脚本xsync

mkdir -p /home/hadoop/bin && cd /home/hadoop/bin
vim xsync

#!/bin/bash

#1. 判断参数个数
if [ $# -lt 1 ]
then
    echo Not Arguement
    exit;
fi

#2. 遍历集群所有机器
for host in node1 node2 node3
do
    echo ====================  $host  ====================
    #3. 遍历所有目录，挨个发送

    for file in $@
    do
        #4. 判断文件是否存在
        if [ -e $file ]
            then
                #5. 获取父目录
                pdir=$(cd -P $(dirname $file); pwd)

                #6. 获取当前文件的名称
                fname=$(basename $file)
                ssh $host "mkdir -p $pdir"
                rsync -av $pdir/$fname $host:$pdir
            else
                echo $file does not exists!
        fi
    done
done

chmod +x xsync.sh

创建jps状态打印

vim /export/server/hadoop/sbin/jpsall.sh

#!/bin/bash
for host in node1 node2 node3
do
        echo =============== $host ===============
        ssh $host $JAVA_HOME/bin/jps
done

chmod +x jpsall.sh

hadoop启动脚本

cd /export/hadoop/sbin

vim exec-hadoop.sh

#!/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 node2 $HADOOP_HOME/sbin/start-dfs.sh
