Ansible Playbook - Setup Storm Cluster.

This is a simple Storm Cluster Setup. We are using a dedicated Zookeeper Cluster/Node, instead of the standalone zkserver. Below is how we will deploy our cluster.

                        / ---- supervisor01
Nimbus[nimbus and ui]----- 
                        \ ---- supervisor02

Before we start.

Download apache-storm-0.9.4.tar.gz to file_archives directory.

Download zookeeper-3.4.5-cdh5.1.2.tar.gz to file_archives directory.

Download jdk-7u75-linux-x64.tar.gz to file_archives directory.

Get the script from Github.

Below is the command to clone.

ahmed@ahmed-server ~]$ git clone https://github.com/zubayr/ansible_storm_tarball

Step 1: Update Hosts File.

Update the host file to reflect your server IPs. Currently hosts file looks as below.

[zookeepernodes]
10.10.18.11 zookeeper_id=1
10.10.18.12 zookeeper_id=2
10.10.18.13 zookeeper_id=3

#
# storm cluster
#

[stormnimbusnodes]
10.10.18.11

[stormsupervisornodes]
10.10.18.12
10.10.18.13

[stormcluster:children]
stormnimbusnodes
stormsupervisornodes

Step 2: Update group_vars information as required.

Update users/password and Directory information in group_vars/all file. Currently we have the below information.

# --------------------------------------
# USERs
# --------------------------------------

zookeeper_user: zkadmin
zookeeper_group: zkadmin
zookeeper_password: $6$rounds=40000$1qjG/hovLZOkcerH$CK4Or3w8rR3KabccowciZZUeD.nIwR/VINUa2uPsmGK/2xnmOt80TjDwbof9rNvnYY6icCkdAR2qrFquirBtT1

storm_user: stormadmin
storm_group: stormadmin
storm_password: $6$rounds=40000$1qjG/hovLZOkcerH$CK4Or3w8rR3KabccowciZZUeD.nIwR/VINUa2uPsmGK/2xnmOt80TjDwbof9rNvnYY6icCkdAR2qrFquirBtT1

# --------------------------------------
# STORM Variables
# --------------------------------------

storm_local_dir: /data/ansible/storm
storm_log_dir: /data/ansible/storm_logging


# --------------------------------------
# COMMON FOR INSTALL PATH
# --------------------------------------

# Common Location information.
common:
  install_base_path: /usr/local
  soft_link_base_path: /opt

Step 3: Update default information in default/main.yml.

Update the default values if required.

Step 4: Executing.

Below is the command.

ahmed@ahmed-server ansible_kafka_tarball]$ ansible-playbook ansible_storm.yml -i hosts --ask-pass
