I'm trying to install Magento open source for the first time.
I have gone through most of the process except the last part. When I try to run:
php bin/magento setup:install --base-url=http://localhost/magento2ee --db-host=localhost --db-name=magento2 --db-user=root --db-password= --admin-firstname=admin --admin-lastname=admin [email protected] --admin-user=admin --admin-password=admin123 --language=en_US --currency=USD --timezone=America/Chicago --use-rewrites=1 or :

--base-url=http://localhost/magento2ee \
--db-host=localhost \
--db-name=magento2 \
--db-user=root \
--db-password= \
--admin-firstname=admin \
--admin-lastname=admin \
[email protected] \
--admin-user=admin \
--admin-password=admin123 \
--language=en_US \
--currency=USD \
--timezone=America/Chicago \
--use-rewrites=1 \
--search-engine=opensearch \
--opensearch-host=os-host.example.com \
--opensearch-port=9200 \
--opensearch-index-prefix=magento2 \

from the Magento documentation, I get the following error:

In SearchConfig.php line 81:

  Could not validate a connection to the OpenSearch. No alive nodes found in your cluster 

I tried checking the source of the issue by testing OpenSearch, and sent couple of requests and it is working:

curl.exe -X GET http://localhost:9200


"name" : "DESKTOP-HD81RFN",
"cluster_name" : "opensearch",
"cluster_uuid" : "HwWhh2IyRIWI_C952vAbkg",
"version" : {
"distribution" : "opensearch",
"number" : "2.6.0",
"build_type" : "zip",
"build_hash" : "7203a5af21a8a009aece1474446b437a3c674db6",
"build_date" : "2023-02-24T19:18:51.456570800Z",
"build_snapshot" : false,
"lucene_version" : "9.5.0",
"minimum_wire_compatibility_version" : "7.10.0",
"minimum_index_compatibility_version" : "7.0.0"
"tagline" : "The OpenSearch Project: https://opensearch.org/"

same result when I check http://localhost:9200/ on my browser.

Another test I did was sending:netstat -ano | find "9200" to see if OpenSearch is listening to the requests on the port, and it is:

TCP               LISTENING       7148
TCP    [::]:9200              [::]:0                 LISTENING       7148
TCP    [::1]:9200             [::1]:64743            ESTABLISHED     7148
TCP    [::1]:64743            [::1]:9200             ESTABLISHED     2125

Now I don't know the possible source of the issue.

Replace --search-engine=opensearch with --search-engine= elasticsearch7, it will solve your issue.

It is intended to bypass the Magento installation/upgrade process, you can change the configuration for the search engine back to OpenSearch afterward by running:

bin/magento config:set catalog/search/engine 'opensearch'

This is an installation/upgrade issue in Magento 2.4.6, see https://github.com/magento/magento2/issues/37236

  • the search engine im using is not elasticsearch7 but rather opensearch, thats why i made it opensearch. do i uninstall opensearch and switch to elasticsearch?

  • No, you don't need. Just use that modification during setup/upgrade Magento, you can switch it back to opensearch after that by running: bin/magento config:set catalog/search/engine 'opensearch'

By default OpenSearch uses SSL, but magento doesn't use it. So it needs to disable SSL plugin in OpenSearch for successful magento installation:

sudo nano /etc/opensearch/opensearch.yml

And add this to the end of yml file:

plugins.security.disabled: true

I get it from there.

  • You also need to un-commet the line: http.port: 9200, for opensearch to listen to an insecure port Commented Sep 28, 2023 at 5:26
  • The comment from Dallas is correct. You need to do this as well.

Try changing --opensearch-host=os-host.example.com
to --opensearch-host=localhost \

HTH, Tom

  • i tried with your suggestion and it returned ``` No arguments expected for "setup:install" command, got "\--base-url=localhost/magento2ee" ```

  • Please post your complete setup:install command with all the parameters. The parameter "opensearch-host" should be set to localhost. Commented Apr 11, 2023 at 12:40
  • php bin/magento setup:install --base-url=http://localhost/magento2ee \--db-host=localhost \--db-name=magento2 \--db-user=root \--db-password= \--admin-firstname=admin \--admin-lastname=admin \[email protected] \--admin-user=admin \--admin-password=admin123 \--language=en_US \--currency=USD \--timezone=America/Chicago \--use-rewrites=1 \--search-engine=opensearch \--opensearch-host=localhost \--opensearch-port=9200 \--opensearch-index-prefix=magento2 \--opensearch-timeout=15

  • for the time being this worked for me, that's why it was weird to me to see localhost/magento2ee

This problem is possibly caused by incorrect configuration of opensearch in core_config_data. Try running the following commands in your SQL console:

update core_config_data set value = "opensearch" where path = "catalog/search/opensearch_server_hostname";

update core_config_data set value = "opensearch" where path = "catalog/search/engine";

update core_config_data set value = "9200" where path = "catalog/search/opensearch_server_port";
  • Using opensearch as hostname did the trick for me. Thank you!

From https://opensearch.org/docs/1.1/security-plugin/configuration/disable/

A more permanent option is to remove the security plugin entirely:

  • Delete the plugins/opensearch-security folder on all nodes.
  • Delete all plugins.security.* configuration entries from opensearch.yml.

Note: plugins.security.disabled: true is still needed in the opensearch.yml file.


I have experienced the similar issue and i have found that Opensearch was working but still it keep displaying "No alive nodes found in your cluster" After spending hours i was able to figure out that security issue Our local website was on http and running the cmd curl http://localhost:9200 returned curl: (52) Empty reply from server

On the other side curl https://localhost:9200 is returning the required result

Solution You need to configure the SSL locally to resolve this issue
