利用脚本批量操作Storm集群

假设有4台机，IP及主机名如下：

192.168.100.105 c1
192.168.100.110 c2
192.168.100.115 c3
192.168.100.120 c4

假设Storm安装在/home/目录下，也就是/home/storm/

* 先登录root账号再进行以下操作

1.创建脚本

创建并赋予运行权限

mk batch-storm.sh
chmod u+x batch-storm.sh

2.编辑脚本

vim batch-storm.sh

添加以下内容：

#!/bin/bash
usage="Usage: $0 (start|stop)"

if [ $# -lt 1 ]; then
  echo $usage
  exit 1
fi

action=$1
iparray=(c1 c2 c3 c4)
path="/home/storm/bin"

echo "$action Storm cluster"

case $action in
    "start")
    echo "$action Nimbus"
    $path/storm nimbus &
    sleep 3s

    for ip in ${iparray[*]}
    do
        echo "ssh to $ip - $action Supervisor"
        ssh $ip $path/storm supervisor &
        sleep 2s
    done

    echo "$action UI"
    $path/storm ui &
    ;;

    "stop")
    echo "$action UI"
    ps -ef|grep UIServer|grep -v grep|awk '{print $2}'|xargs kill -9
    sleep 3s

    for ip in ${iparray[*]}
    do
        echo "ssh to $ip - $action Supervisor"
        # ssh $ip ps -ef|grep Supervisor|grep -v grep|awk '{print $2}'|xargs kill -9
        pid=$(ssh $ip ps -ef | grep Supervisor | grep -v grep | awk '{print $2}')
        ssh $ip "kill -9 ${pid}"
        sleep 2s
    done

    echo "$action Nimbus"
    ps -ef|grep Nimbus|grep -v grep|awk '{print $2}'|xargs kill -9
    ;;
esac

exit 0

3.编辑storm文件

* 该步骤在每台机都要执行

vim /home/storm/bin/storm

添加一行内容：

export JAVA_HOME=/usr/bin/jdk1.8.0

这里的/usr/bin/jdk1.8.0是Java安装目录，请按实际情况修改。

4.运行脚本

只需要在其中一台机运行即可

批量启动：

./batch-storm.sh start

批量停止：

./batch-storm.sh stop
