[iRabi]

Preconditions
After installing modules and enabling them, when I run bin/magento setup:upgrade, I get this error _'Smile_ElasticsuiteCatalog': Installing data... No alive nodes found in your cluster_. When _only_ 'Smile_ElasticsuiteCore' module is enabled, site is working but catalog is appearing blank.

Magento Version : 2.2.4, default Luma theme and demo products.
ElasticSuite Version : v5.3.2
Environment : Developer
Nginx, php 7.1.18

### Steps to reproduce

1. Installed ES modules with phonetic and UCI
2. Verified ES is running with "curl localhost:9200"
3. Followed instructions: https://github.com/Smile-SA/elasticsuite/wiki/ModuleInstall

### Expected result

1. Module should work as expected

### Actual result

1. CLI message:
   Module 'Smile_ElasticsuiteCore':
   Module 'Smile_ElasticsuiteCatalog':
   Installing data... No alive nodes found in your cluster

1. Log report:
   [2018-07-07 21:10:17] main.CRITICAL: No alive nodes found in your cluster {"exception":"[object] (Elasticsearch\Common\Exceptions\NoNodesAvailableException(code: 0): No alive nodes found in your cluster at /var/www/html/espmagento/vendor/elasticsearch/elasticsearch/src/Elasticsearch/ConnectionPool/StaticNoPingConnectionPool.php:51)"} []

Hello, thank you for giving our module a try.

Which instructions did you follow in module install ? In fact, they are all optional if your ES server is running on http://localhost:9200

Could you show me anything related to elasticsuite/elasticsearch as it appears on the core_config_data table during install or in the app/etc/env.php file ?

Regards

Hi,
Followed this instruction: https://github.com/Smile-SA/elasticsuite/wiki/ModuleInstall

Also, there is not any row related to _elasticsuite/elasticsearch_ in _core_config_data_ .

Thanks.

Does the problem still occurs if you clean the cache before running the setup:upgrade script ?

[iRabi]

Hi, I will give a try and let you know.
Thanks.

[afoucret]

Hi @iRabi,

I close this one for having no feedback from you and not being able to reproduce the bug.

[izakarim]

I faced the same issue. Is there any solution for this?

[alexpoletaev]

the next config fixed the problem for me:

'smile_elasticsuite_core_base_settings' => [
                'es_client' => [
                    'servers' => '127.0.0.1:9200',
                    'enable_https_mode' => 0,
                    'enable_http_auth' => 0,
                    'http_auth_user' => '',
                    'http_auth_pwd' => '',
                    'scheme' => 'http'
                ]
            ]

the problem is that the 'false' is a string, it returns true during validation and Magento tries to connect over https.

I'm having the same problem here is my config.

 'system' => [
        'default' => [
            'smile_elasticsuite_core_base_settings' => [
                'es_client' => [
                    'servers' => 'https://*****************.us-west-2.es.amazonaws.com:443',
                    'enable_https_mode' => '0',
                    'enable_http_auth' => '0',
                ]
            ]
        ]
    ] 

[andrewkett]

I changed

 'system' => [
        'default' => [
            'smile_elasticsuite_core_base_settings' => [
                'es_client' => [
                    'servers' => 'elasticsearch:9200',
                    'enable_https_mode' => '0',
                    'enable_http_auth' => '1',
                ]
            ]
        ]
    ] 

to

'system' => [ 'default' => [ 'smile_elasticsuite_core_base_settings' => [ 'es_client' => [ 'servers' => 'elasticsearch:9200', 'enable_https_mode' => 0, 'enable_http_auth' => 1, ] ] ] ]

which resolved this issue for me. It appears the 0 as a string was being evaluated as true as per alexpoletaevs suggestion

[Ahmed-Ayman]

for anyone who is facing the same issue and coming from a docker-compose background!
just change the 'servers' value inapp/etc/env.phpto:in my case it waselasticsearch:9200` since my docker-compose was like

 elasticsearch:
    build: images/elasticsearch
    ports:
      - "9200:9200"
      - "9300:9300"

[LavanyaCS]

i am also facing same issues

[LavanyaCS]

I dono have idea

May I know the proceduere

[LavanyaCS]

Module 'Smile_ElasticsuiteCore':
Module 'Smile_ElasticsuiteCatalog':
Installing data... No alive nodes found in your cluster

check out the comments @LavanyaCS

jeez, having protocol in the host url would break the installation, removing http(s) from url in config fixed it for me.

[mrtuvn]

the next config fixed the problem for me:

'smile_elasticsuite_core_base_settings' => [
                'es_client' => [
                    'servers' => '127.0.0.1:9200',
                    'enable_https_mode' => 0,
                    'enable_http_auth' => 0,
                    'http_auth_user' => '',
                    'http_auth_pwd' => '',
                    'scheme' => 'http'
                ]
            ]

the problem is that the 'false' is a string, it returns true during validation and Magento tries to connect over https.

works like a charm
