A problem occurred when deploying your own small project. In the tomcat server. xml modification, the port 8080 was changed to port 80. When you restart tomcat to access it directly with a domain name, you will find that the access fails. Google found that tomcat uses authbind to specify ports lower than 1023. Authbind is a tool under GNU that helps system administrators specify ports for programs. If your machine does not have authbind installed, you must first install it: sudo apt-get install authbind and then Configure port 80: sudo touch/etc/authbind/byport/80 then start tomcat to access the 80 service: sudo authbind -- deep. /catalina. sh start
