A simple bash script that can set up a Linux node for a 3 node cluster

fusion-3node-cluster-setup.sh

#!/usr/bin/env bash
# Enter each private IP address of each node in this list
zkhost1=IPADDRESS1
zkhost2=IPADDRESS2
zkhost3=IPADDRESS3
zkhost=$zkhost1:9983,$zkhost2:9983,$zkhost3:9983

# Assign an ID to this node.
# This will be the only thing in this script that is unique on each node of the cluster.
# Use increasing IDs starting with 1, 2, 3, etc.
# IMPORTANT: Make sure the ID matches up with the zkhost# from above, or Fusion will not start!
myid=1

# The Fusion home directory. If you are using another version of fusion, update this line.
fusion_dir=$HOME/fusion/3.1.0

# This will create the data/zookeeper directory and create the myid file.
mkdir "$fusion_dir/data/zookeeper"
echo "$myid" > "$fusion_dir/data/zookeeper/myid"

# This will add each server node to the zoo.cfg
echo "server.1=$zkhost1:2888:3888" >> "$fusion_dir/conf/zookeeper/zoo.cfg"
echo "server.2=$zkhost2:2888:3888" >> "$fusion_dir/conf/zookeeper/zoo.cfg"
echo "server.3=$zkhost3:2888:3888" >> "$fusion_dir/conf/zookeeper/zoo.cfg"

# This will add zookeeper host to the agent properties.
echo "" >> "$fusion_dir/conf/fusion.properties"
echo "" >> "$fusion_dir/conf/fusion.properties"
echo "solr.zk.connect = $zkhost" >> "$fusion_dir/conf/fusion.properties"
