Quick Tutorial - Setup a Solr instance

Before we start installing Solr instance on any machine, we should be clear on few concepts.


  • What is Solr?
    • Solr is Apache's product and a fast open-source Java search server.
  • Why we need it?
    • Solr enables you to easily create search engine for websites, databases and files.
  • How can we install it?
    Option 1(for Windows machines) - 
      1. Extract the downloaded Solr package and copy it on C or D drive
      2. Please make sure latest version of Java is installed on machine.
      3. You can start Solr instance by below command:
        java -jar start.jar

      4. By default, Solr will run on port 8983. However you can change it ../etc/Jetty.xml file. Look for <set name="port"><SystemProperty name="jetty.port" default="8983"></set> and change it.
      5. You can keep the below command in .bet file and run it automatically.
        C:\solr-6.1.0\bin\solr" restart -h localhost -p 8984
        
        Option 2(for Mac machines)
        > brew install solr
        Once installed, it should start solr on default port 8983.

 

        Option 3 (using docker images) - 
         > docker pull solr         
        Once docker image is pulled, 
        > docker run -p 8983:8983 solr:latest        
        This should start solr on your local machine and accessible on http://localhost:8983/solr

  • Common issue of Solr and how to solve it?
    When you start creating collections in Solr, you may face this issue on Solr.
    new_core: org.apache.solr.common.SolrException:org.apache.solr.common.SolrException: Could not load conf for core new_core: Error loading solr config from /var/solr/data/new_core/conf/solrconfig.xml
    Solution:
    Copy the folder '    /opt/solr/server/solr/configsets/_default/conf' and paste it in '/var/solr/data/new_core/' folder. Once copied, now create the collection with same name('new_core' in this case) and change schema value from 'schema.xml' to 'managed-schema'. It should create collection successfully.

 Please feel free to send email for any help.

    AJAX Progrraming

    Ajax , shorthand for Asynchronous JavaScript and XML , is a web development technique for creating interactive web applications. The intent is to make web pages feel more responsive by exchanging small amounts of data with the server behind the scenes, so that the entire web page does not have to be reloaded each time the user requests a change. This is meant to increase the web page's interactivity, speed, and usability. The Ajax technique uses a combination of: XHTML (or HTML) and CSS, for marking up and styling information. The DOM accessed with a client-side scripting language, especially JavaScript and JScript, to dynamically display and interact with the information presented. The XMLHttpRequest object is used to exchange data asynchronously with the web server. In some Ajax frameworks and in certain situations, an IFrame object is used instead of the XMLHttpRequest object to exchange data with the web server, and in other implementations, dynamically added tags may be used. ...
