一脸懵逼学习Storm的搭建--（一个开源的分布式实时计算系统）
Storm的官方网址：http://storm.apache.org/index.html 1:集群部署的基本流程(基本套路)： 集群部署的流程：下载安装包、解压安装包、修改配置文件、分发安装包、启动集群; 1：安装一个zookeeper集群，之前已经部署过，这里省略，贴一下步骤； 安装配置zooekeeper集群： 1.1：解压 tar -zxvf zookeeper-3.4.5.tar.gz 1.2：修改配置 cd /home/hadoop/zookeeper-3.4.5/conf/ cp zoo_sample.cfg zoo.cfg vim zoo.cfg 修改：dataDir=/home/hadoop/zookeeper-3.4.5/tmp 在最后添加： server.1=master:2888:3888 server.2=slaver1:2888:3888 server.3=slaver2:2888:3888 保存退出 然后创建一个tmp文件夹 mkdir /home/hadoop/zookeeper-3.4.5/tmp 再创建一个空文件 touch /home/hadoop/zookeeper-3.4.5/tmp/myid 最后向该文件写入ID echo 1 > /home/hadoop/zookeeper-3.4.5/tmp/myid 1.3将配置好的zookeeper拷贝到其他节点： scp -r /home/hadoop/zookeeper-3.4.5/ slaver1:/home/hadoop/ scp -r /home/hadoop/zookeeper-3.4.5/ slaver2:/home/hadoop/ 注意：修改slaver1、slaver2对应/home/hadoop/zookeeper-3.4.5/tmp/myid内容 slaver1： echo 2 > /home/hadoop/zookeeper-3.4.5/tmp/myid slaver2： echo 3 > /home/hadoop/zookeeper-3.4.5/tmp/myid 2、上传storm的安装包，解压缩： [root@master hadoop]# tar -zxvf apache-storm-0.9.2-incubating.tar.gz 3、修改配置文件storm.yaml： 可以创建一个软连接，方便操作storm：[root@master soft]# ln -s apache-storm-0.9.2-incubating storm 修改内容如下所示，下面两个配置均可： #指定storm使用的zk集群 storm.zookeeper.servers: - "zk01" - "zk02" - "zk03" #指定storm集群中的nimbus节点所在的服务器 nimbus.host: "storm01" #指定nimbus启动JVM最大可用内存大小 nimbus.childopts: "-Xmx1024m" #指定supervisor启动JVM最大可用内存大小 supervisor.childopts: "-Xmx1024m" #指定supervisor节点上，每个worker启动JVM最大可用内存大小 worker.childopts: "-Xmx768m" #指定ui启动JVM最大可用内存大小，ui服务一般与nimbus同在一个节点上。 ui.childopts: "-Xmx768m" #指定supervisor节点上，启动worker时对应的端口号，每个端口对应槽，每个槽位对应一个worker supervisor.slots.ports: - 6700 - 6701 - 6702 - 6703 此次配置使用下面的，进行集群安装： #所使用的zookeeper集群主机 storm.zookeeper.servers: - "master" - "slaver1" - "slaver2" #nimbus所在的主机名 nimbus.host: "master"supervisor.slots.ports-6701-6702-6703-6704-6705 然后将master修改好的storm发送到slaver1,slaver2： [root@master hadoop]# scp -r apache-storm-0.9.2-incubating/ slaver1:/home/hadoop/ [root@master hadoop]# scp -r apache-storm-0.9.2-incubating/ slaver2:/home/hadoop/ 4：启动storm集群，首先启动你的Zookeeper集群，然后再启动你的storm集群哈。 启动Zookeeper集群： 然后启动Storm集群： 启动storm 在nimbus主机上，在nimbus.host所属的机器上启动 nimbus服务： nohup ./storm nimbus 1>/dev/null 2>&1 & 或者使用命令：nohup ./storm nimbus &在nimbus.host所属的机器上启动ui服务： nohup ./storm ui 1>/dev/null 2>&1 & 或者使用命令：nohup ./storm ui & 在supervisor主机上，在其它个点击上启动supervisor服务： nohup ./storm supervisor 1>/dev/null 2>&1 & 或者使用命令：nohup ./storm supervisor & 注意，解释： 1>/dev/null：代表标准输入到这个目录； 2>&1：代表标准输出也到这个目录下面； &：代表这个是后台运行； 如下启动storm方便观察，最后一行是卡住不动的哦： 查看进程如下所示： 可以启动一下storm的ui查看： 查看一下进程如： 启动ui以后可以在浏览器访问，如： 启动supervisor [root@slaver1 bin]# ./storm supervisor 然后可以启动剩下的storm： [root@slaver2 bin]# ./storm supervisor 启动以后可以查看进程jps的启动情况，然后可以去浏览器查看自己http://192.168.3.129:8080/index.html的页面各个启动情况，如supervisor等等。 5：Storm常用操作命令： 1：有许多简单且有用的命令可以用来管理拓扑，它们可以提交、杀死、禁用、再平衡拓扑。 提交任务命令格式：storm jar 【jar路径】 【拓扑包名.拓扑类名】 【拓扑名称】 2：bin/storm jar examples/storm-starter/storm-starter-topologies-0.9.6.jar storm.starter.WordCountTopology wordcount 杀死任务命令格式：storm kill 【拓扑名称】 -w 10（执行kill命令时可以通过-w [等待秒数]指定拓扑停用以后的等待时间） 3：storm kill topology-name -w 10 停用任务命令格式：storm deactivte 【拓扑名称】 4：storm deactivte topology-name 5：我们能够挂起或停用运行中的拓扑。当停用拓扑时，所有已分发的元组都会得到处理，但是spouts的nextTuple方法不会被调用。销毁一个拓扑，可以使用kill命令。它会以一种安全的方式销毁一个拓扑，首先停用拓扑，在等待拓扑消息的时间段内允许拓扑完成当前的数据流。 启用任务命令格式：storm activate【拓扑名称】 storm activate topology-name 重新部署任务命令格式：storm rebalance 【拓扑名称】 storm rebalance topology-name 再平衡使你重分配集群任务。这是个很强大的命令。比如，你向一个运行中的集群增加了节点。再平衡命令将会停用拓扑，然后在相应超时时间之后重分配工人，并重启拓扑。 注意使用storm运行jar包的时候是没有输入输出路径的，区别于hadoop离线分析： 1 [root@master
