Hello, I'm trying to Use Elasticsearch to index the Wikipedia dump, but this error appears here ```python elastic_transport.ConnectionError: Connection error caused by: NewConnectionError(: Failed to establish a new connection: [Errno 111] Connection refused) WARNING:elastic_transport.node_pool:Node has failed for 7 times in a row, putting on 30 second timeout WARNING:elastic_transport.transport:Retrying request after failure (attempt 2 of 3) ``` And my config is as follows: ```python 'hostname': 'https://127.0.0.1:9200' , # 'hostname': 'http://localhost:9200', 'index_name': index_name, 'keys': {'title': 'title', 'body': 'txt'}, 'timeout': 600, 'retry_on_timeout': True, 'maxsize': 24, 'number_of_shards': 'default', 'language': 'english', 'file': "${workspaceFolder}/index.html" ``` What's happening. How do I fix it? ---

Hello and welcome to the forum. Hopefully we can get you started ... > [@pengdijie](#): > > `Connection refused` > \ has failed for 7 times in a row There is your first problem. Can you show some evidence that elasticsearch is up and running on the host? How did you setup elasticsearch? > [@pengdijie](#): > > `'hostname': 'https://127.0.0.1:9200'` You don't need to supply any credentials to access elasticsearch? ---

I followed this prompt to install ```python cd data # This is the path where I installed elasticsearch wget -O elasticsearch-8.15.0.tar.gz https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-8.15.0-linux-x86_64.tar.gz # download Elasticsearch tar zxvf elasticsearch-8.15.0.tar.gz rm elasticsearch-8.15.0.tar.gz cd elasticsearch-8.15.0 nohup bin/elasticsearch & # run Elasticsearch in background cd ../.. python prep_elastic.py --data_path data/dpr/psgs_w100.tsv --index_name wiki # build index ``` but when I run ```python nohup bin/elasticsearch ``` that prompt ```python nohup: ignoring input and appending output to 'nohup.out' ``` I thought it had started elasticsearch, and when I run "systemctl status elasticsearch" to checking if the Elasticsearch service is started, The following prompt appears. It confuses me. ```auto System has not been booted with systemd as init system (PID 1). Can't operate. Failed to connect to bus: Host is down ``` --------------------------------------------------------------------------------------------dividing line---------------------------------------------------------------------------------------------------------- "You don't need to supply any credentials to access elasticsearch?" Is this statement saying that I'm missing some credentials? But I'm also just following the project from the github repository, do I need to add any credentials? ---

Hi @pengdijie First and foremost I think you should look at the elasticsearch installation documentation. You appear to making some significant assumption > **[Installing Elasticsearch | Elasticsearch Guide \[8.17\] | Elastic](https://www.elastic.co/guide/en/elasticsearch/reference/current/install-elasticsearch.html#hosted-elasticsearch-service)** `nohup bin/elasticsearch &` From a tar.gz that will start elasticsearch with default security and authentication. You would have gotten authorization creds at startup the first time You should follow [this](https://www.elastic.co/guide/en/elasticsearch/reference/current/targz.html#_check_that_elasticsearch_is_running) first > [@pengdijie](#): > > "systemctl status elasticsearch" to checking if the Elasticsearch service If you want to use `systemctl` you would need to I stall from a package Either way I suggest you go back and look at the installation docs. Then after you can `curl` propely to elasticsearch connecting via Python should be pretty straightforward. ---

As explained, you just need read and follow the standard installations instructions. Is there a good reason to not use the most current release (8.17.3) ? When you follow the installation instructions, then at some point you will learn that (for secure installation, even when using self-signed certificate) there is an "elastic" user, and a password, that you should use to connect to elasticsearch over HTTPS. Elasticsearch is up and running when if you do this: ```auto EUSER="elastic" EPASS="your-elastic-password" EHOST="localhost" EPORT="9200" curl -s -k -u "${EUSER}:${EPASS}" "https://${EHOST}:${EPORT}" ``` you receive something like this: ```auto { "name" : "macmini", "cluster_name" : "my-cluster", "cluster_uuid" : "xxxxxxxxxxxxxxxxxxxxx", "version" : { "number" : "8.17.2", "build_flavor" : "default", "build_type" : "tar", "build_hash" : "747663ddda3421467150de0e4301e8d4bc636b0c", "build_date" : "2025-02-05T22:10:57.067596412Z", "build_snapshot" : false, "lucene_version" : "9.12.0", "minimum_wire_compatibility_version" : "7.17.0", "minimum_index_compatibility_version" : "7.0.0" }, "tagline" : "You Know, for Search" } ``` Good luck. If you get further but still hit issues please just ask again.
