The bin folder has all the scripts primarily needed to get up and running with Solr. Mainly, we will be using Solr and post scripts for our day-to-day purposes. It is also the location to place the replication scripts for more advanced setup, if needed. The bin folder is home to the following utilities: it contains the solr.in.sh and solr.in.cmd files, from where you can provide input parameters to Solr. It has the install_solr_service.sh script and the oom_solr.sh and init.d folders, if you want to run it as a service on any Linux/Unix service.
Since we will be using Solr scripts very often, it is advisable to add $SOLR_HOME/bin (for example, E:solr-7.1.0solr-7.1.0in) in the path environment variable so that we can use it anywhere.
