How to start multiple Tomcat servers and multiple tomcat servers at the same time
If you need to start multiple Tomcat servers on one server, a port conflict will certainly occur under the default settings. To achieve this, you only need to modify the server. xml file in the conf subdirectory. Three modifications are required:

(1). Modify the http access port (default: port 8080 ):

<Connector port = "8080" protocol = "HTTP/1.1 ″
ConnectionTimeout = "20000 ″
RedirectPort = "8443" URIEncoding = "gb2312"/>

(2) modify the Shutdown port (default: Port 8005 ):

<Server port = "8005" shutdown = "SHUTDOWN">

(3) modify the JVM startup port (default: Port 8009 ):

<Connector port = "8009" protocol = "AJP/1.3" redirectPort = "8443"/>
