远程执行命令：runRemoteCmd.sh

#!/bin/bash#set -xif [ $# -lt 2 ]then   echo "Usage: ./runRemoteCmd.sh Command MachineTag"  echo "Usage: ./runRemoteCmd.sh Command MachineTag confFile"  exit ficmd=$1tag=$2if [ 'a'$3'a' == 'aa' ]then    confFile=~/bin/deploy.confelse   confFile=$3fiif [ -f $confFile ]then    for server in `cat $confFile|grep -v '^#'|grep ','$tag','|awk -F',' '{print $1}'`     do       echo "*******************$server***************************"       ssh $server "source ~/.bash_profile; $cmd"    done else  echo "Error: Please assign config file or run runRemoteCmd.sh command with deploy.conf in same directory"fi

 使用示例

将~/.bashrc 分发到所有主机

deploy.sh ~/.bashrc ~/ all

 

runRemoteCmd.sh "source ~/.bashrc" all

 在zookeeper主机上执行cp -rf /home/hadoop/zkdata/* /home/hadoop/zkdata_upgrade命令

runRemoteCmd.sh "cp –rf /home/hadoop/zkdata/* /home/hadoop/zkdata_upgrade" zookeeper
