It’s important to note that the default port might be different if you have configured Solr to run on a different port during installation or in the Solr configuration files. You can check the Solr configuration files, specifically the solr.xml file or the startup scripts, to determine the exact port number.

Keep in mind that for production deployments, it’s common to run Solr behind a web server (e.g., Apache HTTP Server or Nginx) and proxy requests to Solr. In such cases, the port number you use to access Solr may be different based on the web server configuration.
