storm集群搭建和java应用

1. vim /etc/hosts
ssh免密登录
192.168.132.154 c0
192.168.132.156 c1
192.168.132.155 c2

storm集群：
192.168.132.154 c0
192.168.132.156 c1
192.168.132.155 c2

2. 请在官网下载，并解压。文末有文件下载地址
tar -zxvf apache-storm-1.2.3.tar.gz

  配置环境变量（c0,c1,c2都要修改）

vim /etc/profile
# storm
export STORM_HOME=/home/xiaozw/soft/java/storm
export PATH=$PATH:${JAVA_PATH}:$HADOOP_HOME/bin:$HADOOP_HOME/sbin:$ZK_HOME/bin:$SPARK_HOME/bin:${STORM_HOME}/bin
刷新生效
source /etc/profile

3. 修改storm/conf/storm.yaml配置文件

storm.zookeeper.servers:

- "192.168.132.154"
- "192.168.132.156"
- "192.168.132.155"
nimbus.seeds: ["192.168.132.154"]
storm.local.dir:"/home/xiaozw/soft/tmp/storm"
supervisor.slots.ports:
- 6700
- 6701
- 6702
- 6703

  

创建storm目录(c0,c1,c2都要创建)

mkdir /home/xiaozw/soft/tmp/storm

4. 拷贝storm文件夹到其它集群上（c1,c2）
scp -r /home/xiaozw/soft/java/storm root@c1:/home/xiaozw/soft/java/
scp -r /home/xiaozw/soft/java/storm root@c2:/home/xiaozw/soft/java/

先启动zookeeper，安装zookeeper请查看其它文档。
zkServer.sh start
5. 启动storm
c0,nimbus上启动
./storm nimbus >> /dev/null 2>&1 &
启动界面
storm ui >> /dev/null 2>&1 &

  c1,c2 supervisor上启动

./storm supervisor >> /dev/null 2>&1 &
