查看状态信息

 

 

 

1. xcall.sh  查看状态 的命令: xcall.sh jps

      1 #! /bin/bash
      2 
      3 for i in hadoop102 hadoop103 hadoop104
      4 do
      5         echo --------- $i ----------
      6         ssh $i "$*"
      7 done


#!/bin/bash
params=$@

for i in hadoop102 hadoop103 hadoop101
do
　　　　echo ==========s$i $params==========
　　　　ssh $i "source /etc/profile;$params"
done

 

2.复制某个目录到其他节点 xsync

 

      1 #!/bin/bash
      2 #1 获取输入参数个数，如果没有参数，直接退出
      3 pcount=$#
      4 if((pcount==0)); then
      5 echo no args;
      6 exit;
      7 fi
      8 
      9 #2 获取文件名称
     10 p1=$1
     11 fname=`basename $p1`
     12 echo fname=$fname
     13 
     14 #3 获取上级目录到绝对路径
     15 pdir=`cd -P $(dirname $p1); pwd`
     16 echo pdir=$pdir
     17 
     18 #4 获取当前用户名称
     19 user=`whoami`
     20 
     21 #5 循环
     22 for((host=103; host<105; host++)); do
     23         echo ------------------- hadoop$host --------------
     24         rsync -av $pdir/$fname $user@hadoop$host:$pdir
     25 done
       

 

 3.  启动kafka  kafka.sh start

      1 #! /bin/bash
      2 
      3 case $1 in
      4 "start"){
      5         for i in hadoop102 hadoop103 hadoop104
      6         do
      7                 ssh $i "/opt/module/kafka_2.11-1.0.0/bin/kafka-server-start.sh -daemon /opt/module/kafka_2.11-1.0.0/config/server.properties"
      8         done
      9 };;
     10 esac

 

#! /bin/bash

      case $1 in
      "start"){
              for i in hadoop102 hadoop103 hadoop101
             do
                      ssh $i "/opt/module/kafka_2.11-1.0.1/bin/kafka-server-start.sh -daemon /opt/module/kafka_2.11-1.0.1/config/server.properties"
