As Shawn said, it is not recommended, still if you want to do this you can follow these steps(picked from following post http://lucene.472066.n3.nabble.com/Running-Solr-6-3-on-Tomcat-Help-Please-td4320874.html)
The following instructions work with Solr 6.2 + Tomcat 8.5: 1. Copy solr-6.2.0/server/solr-webapp/webapp directory to tomcat/webapps and rename it to 'solr'. 2. Copy solr-6.2.0/server/lib/ext/*.jar and solr-6.2.0/dist/solr-dataimporthandler-*.jar to solr/WEB-INF/lib 3. Uncomment env-entry for solr/home in web.xml and set the value to solr-6.2.0/server/solr 4. Copy solr-6.2.0/server/WEB-INF/resources/log4j.properties to solr/WEB-INF/classes I have tried this and was able to use basic admin ui functions, havn't tried any 6.2+ versions with this. -- View this message in context: http://lucene.472066.n3.nabble.com/Running-Solr6-on-Tomcat7-tp4330500p4331256.html Sent from the Solr - User mailing list archive at Nabble.com.
