Answer 1

If you are using Magento and getting 'No alive nodes found in your cluster' error while reindexing.

Make sure you have updated following :

1. Your Host and port : '[host]:[port]'. Eg: 'es-node1.fqdn:9200, es-node2.fqdn:9200' or 'localhost:9200' in Admin -> Store -> Configuration -> Catalog -> Catalog -> Catalog Search.
2. Update your indices alias name and indices name pattern in admin configuration same as above.

Try this, and clear cache and reindex. It will solve your issue.

Answer 2

If you are using Magento and getting 'No alive nodes found in your cluster' error while reindexing

Please make sure you have install Elastic Search into your system.

if you are using ubantu then please run following command

sudo apt-get install elasticsearch

Then Goto Admin -> Store -> configuration -> catalog -> catalog

then configure as follow

Answer 3

First of all make sure your elasticsearch is installed and running by simply executing this command

curl localhost:9200 If not installed then: sudo apt update

Then run the installation: sudo apt install elasticsearch

First, reload the systemd configuration: sudo systemctl daemon-reload

Then, enable the Elasticsearch service with: sudo systemctl enable elasticsearch.service

And finally, after the service is enabled, start Elasticsearch: sudo systemctl start elasticsearch.service

If you make changes to configuration files, or need to restart Elasticsearch for any reason, use: sudo systemctl restart elasticsearch.service

Then made configuration in admin, that may looks like this, enter image description here

Answer 4

The issue could be caused by configuration as @Khan-arman explained or by elasticsearch service. I discovered both issues below:

Check the configuration

First let's check if your configuration is correct:

1. Update your host and port: '[host]:[port]'. E.g.: 'localhost:9200' in Stores > Settings > Configuration > Catalog > Catalog > Catalog Search or if you are you are using Elastic Suite in Stores > Configuration > ElasticSuit > Basic configuration.

2. Update your indices alias name and indices name pattern in admin configuration same as above.

   

3. Clear cache by going to System > Cache Management or using this command (on your server in Magento installation folder):

   bin/magento cache:clean
   

4. Reindex by visiting System > Index Management or running command below:

   # Update catalog search
   bin/magento indexer:reindex catalogsearch_fulltext 
   
   # Or reindex all indexers
   bin/magento indexer:reindex
   

Check Elasticsearch

If the error still stands, it might be the issue with the elasticsearch service on your server. To solve this follow the steps below:

1. Log into your server

2. Check if the elasticsearch is running:

   sudo /etc/init.d/elasticsearch status
   

3. Try to start it if it's not running, or restart it if it's running:

   # Start elasticsearch
   sudo systemctl start elasticsearch
   
   # Or restart elasticsearch
   sudo systemctl restart elasticsearch
   

   You've found the issue if you encounter an error here and your elasticsearch doesn't start. Solve the issue first. If you don't get any errors and elasticsearch starts, continue.

4. Navigate to your Magento installation folder

5. Reindex all indexers

   bin/magento indexer:reindex
   

6. Clear the cache

   bin/magento cache:flush
   

Your problem should have been solved now.
