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kill -9 pid

3.第二种方式（书写脚本）

4.先新建supervisorHost　

5.书写脚本

 1 #!/bin/bash
 2
 3 STORM_HOME=/etc/opt/modules/storm-0.9.6
 4
 5 #1.停止本机上的nimbus和ui进程
 6
 7 kill -9 `ps -ef | grep daemon.nimbus | awk ‘{print $2}‘|head -n 1`
 8 kill -9 `ps -ef | grep ui.core | awk ‘{print $2}‘|head -n 1`
 9
10
11
12 #2.停止supervisor节点上的supervisor和logviewer进程
13
14 supervisorHost=${STORM_HOME}/bin/supervisorHost
15 supervisors=$(cat $supervisorHost)
16
17 for supervisor in $supervisors
18 do
19     echo "stop supervisor and logviewer in $supervisor"
20     ssh $supervisor "kill -9 `ssh $supervisor ps -ef | grep daemon.supervisor | awk ‘{print $2}‘|head -n 1`" >/dev/null 2>&1
21     ssh $supervisor "kill -9 `ssh $supervisor ps -ef | grep daemon.logviewer | awk ‘{print $2}‘|head -n 1`" >/dev/null 2>&1
22 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

 1 #!/bin/bash
 2
 3
 4 STORM_HOME=/etc/opt/modules/storm-0.9.6
 5 #1.在本机上启动nimbus和ui进程
 6
 7 nohup ${STORM_HOME}/bin/storm nimbus >/dev/null 2>&1 &
 8 nohup ${STORM_HOME}/bin/storm ui >/dev/null 2>&1 &
 9
10 #2.在指定作为Supervisor的服务器上启动supervisor和logviewer
11
12 supervisorHost=${STORM_HOME}/bin/supervisorHost
13 supervisors=$(cat $supervisorHost)
14
15 for supervisor in $supervisors
16 do
17     echo "start supervisor and logviewer in $supervisor"
18     ssh $supervisor "source /etc/profile && nohup ${STORM_HOME}/bin/storm supervisor >/dev/null 2>&1" >/dev/null 2>&1 &
19     ssh $supervisor "source /etc/profile && nohup ${STORM_HOME}/bin/storm logviewer >/dev/null 2>&1" >/dev/null 2>&1 &
20 done
