You need to do some steps to activate the solr logging to file. By default it writes logs to console. While starting the Solr instance pass the following parameter to enable Solr logging to file.

-Djava.util.logging.config.file=etc/logging.properties

Modify your /example/etc/logging.properties for you Solr instance to customize your logging pattern. After restarting you'll see it's writing the logs into solr0.log file.
