storm集群配置
storm配置相当简单
安装
tar -zxvf apache-storm-1.2.2.tar.gzrm apache-storm-1.2.2.tar.gzmv apache-storm-1.2.2 stormsudo vim /etc/profile export STORM_HOME=/usr/local/storm export PATH=$PATH:$STORM_HOME/binsource /etc/profileapt install python准备 master worker1 worker2 worker3 这四台机器首先确保你的zookeeper集群能够正常运行worker1 worker2 worker3为zk集群具体配置参照我的博客https://www.cnblogs.com/ye-hcj/p/9889585.html
修改配置文件
storm.yaml
sudo vim storm.yaml在四台机器中都加入如下配置 storm.zookeeper.servers: - "worker1" - "worker2" - "worker3" storm.local.dir: "/usr/local/tmpdata/storm" supervisor.slots.ports: - 6700 - 6701 - 6702 - 6703 nimbus.seeds: ["master"] storm.zookeeper.port: 2181 // 不加下面这几个你的拓扑直接跑不起来 nimbus.childopts: "-Xmx1024m" supervisor.childopts: "-Xmx1024m" worker.childopts: "-Xmx768m"
启动
在master中运行 storm nimbus >> /dev/null & storm ui >/dev/null 2>&1 &在worker1，worker2，worker3中运行 storm supervisor >/dev/null 2>&1 & storm logviewer >/dev/null 2>&1 &直接访问http://master:8080即可
使用java编写拓扑
四个文件如图
