Strom的集群停止以及启动

一：停止

1.概述

　　关于strom没有停止命令

2.第一种方式（kill）

　　jps之后

　　使用bin/strom -kill wordcount

3.第二种方式（书写脚本）

4.先新建supervisorHost　

5.书写脚本

　　

#!/bin/bash

STORM_HOME=/etc/opt/modules/storm-0.9.6

#1.停止本机上的nimbus和ui进程

kill -9 `ps -ef | grep daemon.nimbus | awk '{print $2}'|head -n 1`
kill -9 `ps -ef | grep ui.core | awk '{print $2}'|head -n 1`



#2.停止supervisor节点上的supervisor和logviewer进程

supervisorHost=${STORM_HOME}/bin/supervisorHost
supervisors=$(cat $supervisorHost)

for supervisor in $supervisors
do
    echo "stop supervisor and logviewer in $supervisor"
    ssh $supervisor "kill -9 `ssh $supervisor ps -ef | grep daemon.supervisor | awk '{print $2}'|head -n 1`" >/dev/null 2>&1
    ssh $supervisor "kill -9 `ssh $supervisor ps -ef | grep daemon.logviewer | awk '{print $2}'|head -n 1`" >/dev/null 2>&1
done

二：启动

1.正常命令启动

2.新建supervisorHost

　　方便寻找supervisor的pid

　　

3.书写脚本

　　

#!/bin/bash


STORM_HOME=/etc/opt/modules/storm-0.9.6
#1.在本机上启动nimbus和ui进程

nohup ${STORM_HOME}/bin/storm nimbus >/dev/null 2>&1 &
nohup ${STORM_HOME}/bin/storm ui >/dev/null 2>&1 &

#2.在指定作为Supervisor的服务器上启动supervisor和logviewer

supervisorHost=${STORM_HOME}/bin/supervisorHost
supervisors=$(cat $supervisorHost)

for supervisor in $supervisors
do
    echo "start supervisor and logviewer in $supervisor"
    ssh $supervisor "source /etc/profile && nohup ${STORM_HOME}/bin/storm supervisor >/dev/null 2>&1" >/dev/null 2>&1 &
    ssh $supervisor "source /etc/profile && nohup ${STORM_HOME}/bin/storm logviewer >/dev/null 2>&1" >/dev/null 2>&1 &
done
