How To Install Apache Storm into CentOS 6

About Storm:
Storm is a free and open source distributed real time computation system. Storm makes it easy to reliably process unbounded streams of data, doing for real time processing what Hadoop did for batch processing. Storm is simple, can be used with any programming language, and is a lot of fun to use!

Prerequisites:
1. Install Jdk 1.7
2. Install Zookeeper

Download Following rpms:

zeromq-2.1.7-1.el6.x86_64.rpm
jzmq-2.1.0.el6.x86_64.rpm

storm-0.9.0-rc2.zip

sudo rpm -Uvh zeromq-2.1.7-1.el6.x86_64.rpm
sudo rpm -Uvh jzmq-2.1.0.el6.x86_64.rpm
sudo groupadd -g 53001 storm
sudo useradd -u 53001 -g 53001 -d /home/storm/ -s /bin/bash storm -c "Storm service account"
sudo chmod 750 /home/storm/

su - storm

unzip download/0.9.0-rc2.zip
sudo chown -R storm:storm storm-0.9.0.1
ln -s storm-0.9.0.1 storm

mkdir -p /home/storm/data
sudo chown -R storm:storm  /home/storm/data
sudo chmod 750  /home/storm/data
cd /home/storm/conf/
mv storm.yaml storm.yaml.ori
vim storm.yaml 

storm.zookeeper.servers:
 - ""
nimbus.host: "localhost"
nimbus.childopts: "-Xmx1024m -Djava.net.preferIPv4Stack=true"
ui.childopts: "-Xmx768m -Djava.net.preferIPv4Stack=true"
supervisor.childopts: "-Djava.net.preferIPv4Stack=true"
worker.childopts: "-Xmx768m -Djava.net.preferIPv4Stack=true"
storm.local.dir: "/home/storm/data"

ui.port: 8080

supervisor.slots.ports:
 - 6700
 - 6701
 - 6702
 - 6703

For Supervisor you need following configuration:

storm.zookeeper.servers:
 - "your zookeeper server ip:port"
nimbus.host: "nimbus-host-ip"
nimbus.childopts: "-Xmx1024m -Djava.net.preferIPv4Stack=true"
ui.childopts: "-Xmx768m -Djava.net.preferIPv4Stack=true"
supervisor.childopts: "-Djava.net.preferIPv4Stack=true"
worker.childopts: "-Xmx768m -Djava.net.preferIPv4Stack=true"
storm.local.dir: "/home/storm/data"

If supervisor is in same box then above supervisor configuration is not required.

That's It from storm side
