修改Tomcat端口号

8080是Tomcat服务器的默认端口号。我们可以通过修改Tomcat/conf文件夹下的主配置文件server.xml来更改端口号。用记事本打开server.xml文件，找出出现以下代码的部分：

    <!-- A "Connector" represents an endpoint by which requests are received
         and responses are returned. Documentation at :
         Java HTTP Connector: /docs/config/http.html (blocking & non-blocking)
         Java AJP  Connector: /docs/config/ajp.html
         APR (HTTP/AJP) Connector: /docs/apr.html
         Define a non-SSL HTTP/1.1 Connector on port 8080
    -->
    <Connector port="8080" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="8443" />

将其中port="8080"更改为新的端口号即可，比如将8080更改为8081等。
