云服务器配置的tomcat8080端口可以访问，改成80端口就无法访问了

Question

云服务器配置的tomcat8080端口可以访问，改成80端口就无法访问tomcat了

我已经在防火墙中开启了这个端口，不过这个好像是默认开启的端口，但是tomcat的关闭时报了图三的异常

报了以下下异常

同学好，需要你查看下80端口的时候tomcat有没有启动成功，看看tomcat logs/catalina.log尾部是否报错，如果启动成功，那么请你检查相关服务器的安全组策略，确保80端口已经开放

  老师，您看一下我的tomcat logs/catalina.log的日志，报了这个异常

  非常感谢！

  /usr/local/src/java/tomcat7/webapps/upload does not exist or is not a readable directory
  这个错误说的是同学你的/usr/local/src/java/tomcat7/webapps/upload这个目录地址不是可读的，你可以用root帐号chmod 777 -R /usr/local/src/java/tomcat7/webapps/upload 修改下目录权限，前提是这些目录已经创建好了
