Logstash: Unable to connect to external Amazon RDS Database

问题

Am relatively new to logstash & Elasticsearch...

Installed logstash & Elasticsearch using on macOS Mojave (10.14.2):

brew install logstash
brew install elasticsearch

When I check for these versions:

brew list --versions

Receive the following output:

elasticsearch 6.5.4
logstash 6.5.4

When I open up Google Chrome and type this into the URL Address field:

localhost:9200

This is the JSON response that I receive:

{
    "name" : "9oJAP16",
    "cluster_name" : "elasticsearch_local",
    "cluster_uuid" : "PgaDRw8rSJi-NDo80v_6gQ",
    "version" : {
        "number" : "6.5.4",
        "build_flavor" : "oss",
        "build_type" : "tar",
        "build_hash" : "d2ef93d",
        "build_date" : "2018-12-17T21:17:40.758843Z",
        "build_snapshot" : false,
        "lucene_version" : "7.5.0",
        "minimum_wire_compatibility_version" : "5.6.0",
        "minimum_index_compatibility_version" : "5.0.0"
    },
    "tagline" : "You Know, for Search"
}

Inside:

/usr/local/etc/logstash/logstash.yml

Resides the following variables:

path.data: /usr/local/Cellar/logstash/6.5.4/libexec/data
pipeline.workers: 2
path.config: /usr/local/etc/logstash/conf.d
log.level: info
path.logs: /usr/local/var/log

Inside:

/usr/local/etc/logstash/pipelines.yml

Resides the following variables:

- pipeline.id: main
path.config: "/usr/local/etc/logstash/conf.d/*.conf"

Have setup the following logstash_etl.conf file underneath:

/usr/local/etc/logstash/conf.d

Its contents:

input {
    jdbc {
       jdbc_connection_string => "jdbc:mysql://myapp-production.crankbftdpmc.us-west-2.rds.amazonaws.com:3306/products"
       jdbc_user => "products_admin"
       jdbc_password => "products123"
       jdbc_driver_library => "/etc/logstash/mysql-connector/mysql-connector-java-5.1.21.jar"
       jdbc_driver_class => "com.mysql.jdbc.driver"
       schedule => "*/5 * * * *"
       statement => "select * from products"
       use_column_value => false
       clean_run => true
    }
}

# sudo /usr/share/logstash/bin/logstash-plugin install logstash-output-exec
output {
   if ([purge_task] == "yes") {
         exec {
             command => "curl -XPOST 'localhost:9200/_all/products/_delete_by_query?conflicts=proceed' -H 'Content-Type: application/json' -d'
                 {
                   \"query\": {
                     \"range\" : {
                       \"@timestamp\" : {
                         \"lte\" : \"now-3h\"
                       }
                     }
                   }
                 }
             '"
        }
    } 
    else {
        stdout { codec => json_lines}
        elasticsearch {
            "hosts" => "localhost:9200"
            "index" => "product_%{product_api_key}"
            "document_type" => "%{[@metadata][index_type]}"
            "document_id" => "%{[@metadata][index_id]}"
            "doc_as_upsert" => true
            "action" => "update"
            "retry_on_conflict" => 7
        }
    }
}

When I do this:

brew services start logstash

Receive the following inside my /usr/local/var/log/logstash-plain.log file:

[2019-01-15T14:51:15,319][INFO ][logstash.pipeline        ] Pipeline started successfully {:pipeline_id=>"main", :thread=>"#<Thread:0x399927c7 run>"}

What am I possibly doing wrong?

Is there a way to obtain a dump (e.g. mysqldump) from an Elasticsearch server (Stage or Production) and then reimport into a local instance running Elasticsearch without using logstash?

This is the same configuration file that works inside an Amazon EC-2 Production Instance but don't know why its not working in my local macOS Mojave instance?
