Switching from Solr to Elasticsearch in PoolParty

Stop PoolParty  ./bin/poolparty stop

Copy the below transition script (migrate_solr_to_elasticsearch) and paste it to the bin/ directory of your PoolParty installation.

#!/bin/bash

DIR_SCRIPT=$(cd -- "$(dirname -- "${BASH_SOURCE[0]}")" &>/dev/null && pwd)
POOLPARTY_CONF="${DIR_SCRIPT}"/../config/poolparty.conf
INSTALLER_PROPERTIES="${DIR_SCRIPT}"/../config/installer.properties
DIR_ES="${DIR_SCRIPT}"/../index/elasticsearch

# Start ES
if [[ $EUID -eq 0 ]]; then
        run_as=$(ls -l "$DIR_SCRIPT/elasticsearch" | awk '{print $3}')
	su - $run_as -c "$DIR_SCRIPT/elasticsearch start"
else
	$DIR_SCRIPT/elasticsearch start
fi

INTERVAL=5

# Check if Elasticsearch is listening on port 9200 using lsof
while [ $ELAPSED -lt $TIMEOUT ]; do
    if lsof -i :9200 | grep -q LISTEN; then
        echo "Elasticsearch is up and running on port 9200."
        break
    else
        echo "Elasticsearch is not up yet. Retrying... (Elapsed: $ELAPSED seconds)"
    fi

    # Increment the elapsed time and wait for the next interval
    ELAPSED=$((ELAPSED + INTERVAL))
    sleep $INTERVAL
done

if [ $ELAPSED -ge $TIMEOUT ]; then
    echo "Elasticsearch did not start within the timeout period."
    exit 1

# Reset the password for the elastic user and capture the output
PASSWORD_OUTPUT=$(echo "y" | "${DIR_ES}"/bin/elasticsearch-reset-password -u elastic 2>/dev/null)

# Extract the new password from the output using grep with Perl-compatible regular expressions
PASSWORD_ES=$(echo "$PASSWORD_OUTPUT" | grep -oP 'New value: \K.*')

cp "${POOLPARTY_CONF}" "${POOLPARTY_CONF}".bak
sed -i 's/^builtin=true/builtin=false/' "${POOLPARTY_CONF}"
sed -i 's/^ES_START=false/ES_START=true/' "${POOLPARTY_CONF}"


# create installer.properties
{
	echo "index.type=ELASTICSEARCH"
	echo "index.host=http://localhost:9200"
	echo "index.username=elastic"
	echo "index.password=${PASSWORD_ES}"
} > "${INSTALLER_PROPERTIES}"


echo "New ES password: ${PASSWORD_ES}"

Navigate to the bin directory and run the script by executing ./migrate_solr_to_elasticsearch

This script performs several tasks:

Script output

Initial upstart: Start PoolParty. Initially, the status of the index may be shown in RED in the Semantic Middleware Configurator indicating that it has to be started again.

Restart PoolParty: Restart PoolParty to complete the integration of Elasticsearch which will be reflected by showing the status of the index in GREEN.
