The http, ajp12, and/or ajp13 services can't bind to the same port on
the same IP address. You need to modify server.xml to put things
on different ports or different IP addresses.

For development, we're doing exactly that: starting five different Tomcat

It is possible: You must have two different server.xml files. In the
server.xml file you can configure that port in the http connector
element. You also need to have 2 startup-scripts that call tomcat with
the appropriate server.xml file. You don't need Apache to do this.
Bye,

Also, when you start tomcat, use the -r option to point to the correct
server.xml file.
ex:
tomcat-start -r /usr/local/tomcat/conf/server-2.xml
tomcat-start -r /usr/local/tomcat/conf/server-1.xml
Where server-1.xml defines tomcat on port 8001, and server-2 defines
tomcat on 8002.

Yes, I've done this. You need to hand-tailor workers.properties (I copied
