If you have
installed a Storm cluster using my shell scripts in the previous blogs or even
otherwise, this script will save you from manually visiting each node and
starting the appropriate service(nimbus/supervisor/ui) there. All you have to
do is grab a remote machine and run the script. The script will ask for the
required information and your cluster would be up. Also, the script should work
equally fine for both Ubuntu and CentOS.
#!/bin/bash
# Directory Name
echo "Enter
the relative path to the storm setup on the machines (For example,
/opt/stormSetup/storm-0.9.0-wip4):"
read -e stormDir
# Read usernames
and ips of all the storm cluster nodes
echo "Enter
the IP of nimbus machine :"
read -e
stormNimbus;
clusterMachineIPs[0]=$stormNimbus
echo "Enter
the username of nimbus :"
read -e
usernameNimbus
clusterMachineUsernames[0]=$usernameNimbus
# Read supervisor
echo "Enter
the number of supervisor machines";
read -e n;
for (( i = 1 ;
i <= n; i++ ))
do
echo "Enter
the IP of storm supervisor machine $i:"
read -e
stormSupervisor;
clusterMachineIPs[i]=$stormSupervisor
echo "Enter
the username of machine ${clusterMachineIPs[i]}"
read -e username
clusterMachineUsernames[i]=$username
done
sshpass -p root
ssh -o StrictHostKeyChecking=no
$usernameNimbus@$stormNimbus $stormDir/bin/storm nimbus&
# Start the
supervisor nodes
for (( i = 1 ;
i <= n; i++ ))
do
sshpass -p root
ssh -o StrictHostKeyChecking=no ${clusterMachineUsernames[i]}@${clusterMachineIPs[i]}
$stormDir/bin/storm supervisor&
done
# Start the UI on
the nimbus machine
sshpass -p root
ssh -o StrictHostKeyChecking=no
$usernameNimbus@$stormNimbus $stormDir/bin/storm ui&

Visit your UI on
the browser after a few minutes. Hope it shows up fine. Cheers!
