You have configured Tomcat for ports 80 and 443. When you start httpd:

... you get a port conflict. You have to choose: httpd or Tomcat on port
80 (and 443).

It looks like you started configuring for mod_jk, but didn't really
finish. What you have to do is proxy *all* applications from http ->
Tomcat. Then remove the HTTP <Connectors> from Tomcat and rely
exclusively on the AJP connector(s). (You really only need one single
AJP connector, since it will forward TLS information across to Tomcat.)
