Tomcat 拒绝在端口 8080 上工作

Question

如果之前有人问过这个问题，我很抱歉。

我有一个 Amazon 实例 (Ubuntu Server 12.04.1 LTS) 并安装了 Tomcat 版本 (Apache Tomcat/6.0.36)。它在端口 80 上按预期工作，但在端口 8080 上不工作。(不工作意味着“无法连接到 Web 应用程序管理器”)。

• 我的安全组配置为 http* 打开了端口 8080

22 (SSH)    0.0.0.0/0   Delete
80 (HTTP)   0.0.0.0/0   Delete
8080 (HTTP*)    0.0.0.0/0   Delete

• I have both jdk and jre installed, even I do not know why I need jdk if tomcat running on port 8080.
• I have configured tomcat to bind on IPV4 address by having

<Connector port="8080" protocol="HTTP/1.1" 
               connectionTimeout="20000" 
               redirectPort="8443" address="0.0.0.0"/>

at server.xml and adding

JAVA_OPTS="$JAVA_OPTS -Djava.net.preferIPv4Stack=true"
echo $JAVA_OPTS

to setenv.sh

Runnung netstat -ln gives me

那么，我错过了什么吗？

谢谢!!

Answer 1

登录 AWS 控制台并导航至安全组。

1. 删除 HTTP (80)(如果有)。
2. 选择自定义 TCP 规则并输入端口“8080”
3. 点击应用规则。

添加 DNS 名称:8080

现在应该可以了。
