Tomcat拒绝在端口8080上工作

Question

• 我的安全组配置已为http*
打开端口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

• 我既安装了jdk又安装了jre，即使我不知道如果tomcat在端口8080上运行，为什么还需要jdk。
• 我已将tomcat配置为绑定IPV4地址，方法是使用

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

在server.xml中添加

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

登录AWS控制台并导航到安全组。

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

添加DNS名称：8080
