linux上启动tomcat远程不能访问

Question

大神们，我在腾讯上买了个云服务器，上面安装了jdk7 和 tomcat7

这是配置好了jdk

[root@VM_125_9_centos bin]# java -version
java version "1.7.0_79"
Java(TM) SE Runtime Environment (build 1.7.0_79-b15)
Java HotSpot(TM) 64-Bit Server VM (build 24.79-b02, mixed mode)

这是关闭了防火墙

[root@VM_125_9_centos bin]# service iptables status
iptables: Firewall is not running.

这是启动了tomcat

这是查看跟java相关的服务

[root@VM_125_9_centos logs]# ps -ef | grep java
root     12070     1  0 22:39 pts/1    00:00:03 /home/java_file/jdk7/jre/bin/java -Djava.util.logging.config.file=/home/java_file/tomcat-6/conf/logging.properties -Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager -Djava.endorsed.dirs=/home/java_file/tomcat-6/endorsed -classpath /home/java_file/tomcat-6/bin/bootstrap.jar -Dcatalina.base=/home/java_file/tomcat-6 -Dcatalina.home=/home/java_file/tomcat-6 -Djava.io.tmpdir=/home/java_file/tomcat-6/temp org.apache.catalina.startup.Bootstrap start
root     12629  3242  0 22:47 pts/1    00:00:00 grep java

这是查看有没有8080这个商品启动

[root@VM_125_9_centos java_file]# netstat -nlt |grep 8080
tcp        0      0 0.0.0.0:8080                0.0.0.0:*                   LISTEN 

请问我这些都显示的是正常的为什么我还是不能够远程访问启动的tomcat     浏览器输入我的 ip:8080但是不能够访问请问是什么原因，还是我有什么地方漏掉了，最近几天开始学习linux想在上面发布个网站，到这里就遇到问题了，请大神们帮我分析分析，不胜感激。

Answer 1

ping能够ping通，但是telnet在windows上说不是内部或外部命令，在linux上command not found 。我在网上找，有很多人都说用telnet 但是一次都没成功过，这个命令是怎么用的啊。

Answer 2

回复
windows telnet是在windows功能中默认没开启，打开方式如下：控制面板→程序→程序和功能（打开或关闭windows功能）→在相关telnet功能前打钩保存即可；linux 默认没有安装telnet，采用yum -y install telnet，telnet的使用方式是 telnet ip port

Answer 3

输入的是外网ip吗？ ping  或者telnet ip 8080什么结果？

Answer 4

我是新手，不是很懂，你有什么好的经验和技巧，多谢指教。

Answer 5

用root启动服务简直作大死

Answer 6

执行了还是不能访问，而且我用远程连接linux中的mysql也不能连接上，mysql中我修改了host 为'%',是不是云服务器有什么限制啊

Answer 7

回复
云服务器？哪家的哦，我用过阿里云的，没限制啊

Answer 8

回复
我用的是腾讯的，昨天才买的，这几天学了几个linux命令就想玩一下，没想到一来就出了这么个问题。

Answer 9

你试一试这个“iptables -F”然后再访问，如果能够访问了，那么需要执行“firewall-cmd --add-port=8080/tcp --permanent”保证以后也可以访问
