The problem is in the title. after alfresco starts there is the following exception in the catalina.out file:
ERROR [solr.tracker.CoreTracker] [SolrTrackerScheduler_Worker-1] Tracking failed

I looked at this theme but didn't understand much and the what I understood didn't help.
I must say that I'm trying to start tomcat with my alfresco.war at the server with the centOS installed. When I've tryed to start tomcat with my alfresco.war on my windows it worked well.
reinstalling alfresco solved the problem
