求救，阿里云Linux服务器Tomcat报错，被折磨了一下午也没找到问题出在哪儿。

Question

我的流程：1、阿里云Linux，重装系统盘CentOS7.6 x64，清空磁盘内容。2、用Xftp传输apache-tomcat-7.0.82和jdk-7u80-linux-x64.tar.gz并用指令解压。3、向etc/profile内export JAVA环境变量并用sorce刷新文件。4、用vim指令更改Tomcat/conf/server.xml中的8080接口为80。5、转到/bin目录下启动startup.sh，可ping通但外网无法访问，随后启动shutdown.sh。
第5步的控制台内容如下：

[root@iZj6c1q38vbvbchvmhrp3gZ bin]# ./startup.sh

Using CATALINA_BASE: /usr/web/apache-tomcat-7.0.82
Using CATALINA_HOME: /usr/web/apache-tomcat-7.0.82
Using CATALINA_TMPDIR: /usr/web/apache-tomcat-7.0.82/temp
Using JRE_HOME: /usr/web/jdk1.7.0_80/jre
Using CLASSPATH: /usr/web/apache-tomcat-7.0.82/bin/bootstrap.jar:/usr/web/apache-tomcat-7.0.82/bin/tomcat-juli.jar
Tomcat started.

[root@iZj6c1q38vbvbchvmhrp3gZ bin]# ./shutdown.sh

不尽感激！！！！

tomcat start启动后，你是80端口外网是不能访问的，需要备案，你可以改成8888端口试试。
