5. 打开浏览器, 地址栏输入http://localhost:8080 或 http://127.0.0.1:8080

如果出现tomcat示例主页，则表示服务器安装成功

 

如果8080端口被占用了，可以修改tomcat的访问端口
找到 D:\Tomcat\apache-tomcat-9.0.20-windows-x64\apache-tomcat-9.0.20\conf 目录下的 server.xml
打开该文件, 找到以下内容
    <Connector port="8080" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="8443" />

将其中的 port="8080" 改为 port="9090"(或者其他端口即可)
