虽然server.xml指定了不同的端口号，但Tomcat从端口8080开始。为什么呢？

Question

我收到此错误

"Catalina";  Protocol handler start failed: 
java.net.BindException: Address already in use: JVM_Bind <null>:8080`. 

这是因为我在该端口上运行了JIRA。

对于Tomcat，我在9001中指定了端口server.xml但是当它启动时，我的地址已经在使用中。

我似乎无法弄清楚为什么会这样。

server.xml中

 <?xml version='1.0' encoding='utf-8'?>
   <Server port="8005" shutdown="SHUTDOWN">
