Configuring Solr Standalone

Use the following procedure to configure Solr Standalone.

Download the solr_for_audit_setup_v3 file to the /usr/local/ directory:

wget https://issues.apache.org/jira/secure/attachment/12761323/solr_for_audit_setup_v3.tgz -O /usr/local/solr_for_audit_setup_v3.tgz

Use the following commands to switch to the /usr/local/ directory and extract the solr_for_audit_setup_v3 file.
```
cd /usr/local
tar xvf solr_for_audit_setup_v3.tgz
```
The contents of the .tgz file will be extracted into a /usr/local/solr_for_audit_setup_v3 directory.
Use the following command to switch to the /usr/local/solr_for_audit_setup_v3 directory.
```
cd /usr/local/solr_for_audit_setup
```
