tomcat正在运行，但8080端口没有响应
tomcat正在运行，但8080端口没有响应
提问于 2011-12-19 04:44:12
我已经通过ssh在linux x64机器上安装了sun JDK1.6 x64和tomcat，我没有超级用户权限，所以我把它们都安装在我的主目录中。
我设法成功地运行了tomcat，但是如果我尝试进入mydomain.com:8080，服务器没有应答。
使用以下命令：
netstat -atnp|grep LISTEN我检查了端口，它正在侦听

第一步是在本地登录时运行telnet localhost 8080。然后键入类似于
GET /而且你应该把HTML找回来。如果这不起作用，那么tomcat并没有真正正常运行，或者没有在端口8080上侦听。如果可以，但在从外部尝试时，请确保您拥有正确的ip地址。请先尝试使用ip地址。如果ip地址正常工作，可能您的mydomain.com没有解析到它。如果ip是正确的(也就是您要ssh的那个)，但它仍然不能工作，那么您可能正在运行不允许8080通过的防火墙。更改防火墙配置需要root访问权限。

尝试列出在linux终端TCP和端口引用应用程序上使用以下命令，如"java“，如下所示。
[root@h5 ~]# netstat -ltnp | grep java -i --colour
tcp 0 0 10.15.11.20:9990 0.0.0.0:* LISTEN 1626/java
tcp 0 0 10.15.11.20:8080 0.0.0.0:* LISTEN 1626/java
tcp 0 0 10.15.11.20:8443 0.0.0.0:* LISTEN 1626/java 此外，首先您需要检查防火墙上的开放端口。
firewall-cmd --list-ports如果它打开了，但端口不在那里，请允许相关的端口8080，如下所示。
firewall-cmd --permanent --zone=public --add-port=8080
firewall-cmd --reloadStack Overflow用户

在CentOs上，我必须手动打开防火墙
sudo firewall-cmd --zone=public --add-port=7999/tcp --permanent
sudo firewall-cmd --reload不知道是怎么做到的，但是如果Docker在同一个端口上运行一个容器，它会自动打开防火墙，所以就把我踢开了
