Make sure the /var/lib/tomcat7/solr/ is the tomcat user.

sudo chown -R tomcat /var/lib/tomcat7/solr/

Then restart tomcat.

Answer 3

For me I have to update

vi $CATALINA_HOME/webapps/solr/WEB-INF/web.xml

Un-comment and update :

<env-entry>
   <env-entry-name>solr/home</env-entry-name>
   <env-entry-value>/opt/solr/example/solr</env-entry-value>
   <env-entry-type>java.lang.String</env-entry-type>
</env-entry>
