远程执行命令和文件分发shell脚本

deploy.conf

node01,all,other,datanode,journalnode,zookeeper,
node02,all,other,datanode,journalnode,zookeeper,
node03,all,other,datanode,journalnode,zookeeper,
node04,all,other,namenode,
node05,all,other,namenode,

 文件分发:deploy.sh

#!/bin/bash
#set -x

if [ $# -lt 3 ]
then 
  echo "Usage: ./deply.sh srcFile(or Dir) descFile(or Dir) MachineTag"
  echo "Usage: ./deply.sh srcFile(or Dir) descFile(or Dir) MachineTag confFile"
  exit 
fi

src=$1
dest=$2
tag=$3
if [ 'a'$4'a' == 'aa' ]
then
  confFile=~/bin/deploy.conf
else 
  confFile=$4
fi

if [ -f $confFile ]
then
  if [ -f $src ]
  then
    for server in `cat $confFile|grep -v '^#'|grep ','$tag','|awk -F',' '{print $1}'` 
    do
       scp $src $server":"${dest}
    done 
  elif [ -d $src ]
  then
    for server in `cat $confFile|grep -v '^#'|grep ','$tag','|awk -F',' '{print $1}'` 
    do
       scp -r $src $server":"${dest}
    done 
  else
      echo "Error: No source file exist"
  fi

else
  echo "Error: Please assign config file or run deploy.sh command with deploy.conf in same directory"
fi

远程执行命令：runRemoteCmd.sh

#!/bin/bash
#set -x

if [ $# -lt 2 ]
then 
  echo "Usage: ./runRemoteCmd.sh Command MachineTag"
  echo "Usage: ./runRemoteCmd.sh Command MachineTag confFile"
  exit 
fi

cmd=$1
tag=$2
if [ 'a'$3'a' == 'aa' ]
then
  
  confFile=~/bin/deploy.conf
else 
  confFile=$3
fi

if [ -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
