Enabling non root user to run tomcat with port 443

问题

I am trying to run tomcat with https as a non-root user. Configured server.xml with required port modification and added SSL configuration.

However when I execute sudo systemctl restart tomcat get following error in catalina.out

 org.apache.coyote.AbstractProtocol.init Failed to initialize end point associated with ProtocolHandler ["https-jsse-nio-443"]
      java.net.SocketException: Permission denied
