Connection refused when running "solr create"

Question

I'm trying to automate the creation of new collections using the solr create command in Solr 8.11.1 as follows

sudo -u solr /opt/solr/bin/solr create -c collection_name

However, I get connection refused since Solr is listening on the host IP address, not localhost

ERROR: Connect to localhost:8983 [localhost/127.0.0.1] failed: Connection refused (Connection refused)

Is there a way to specify a hostname/IP address when running solr create?

Answer 1

You can set the hostname used for the bin/solr script through the SOLR_HOST environment variable:

export SOLR_HOST=<ip>
sudo -u solr /opt/solr/bin/solr create -c collection_name
