aws中有一个64位的amazon linux实例。 我正在运行在该机器上运行的Apache Tomcat6。
sudo fuser -v -n tcp 8080 USER PID ACCESS COMMAND 8080/tcp: tomcat 2492 F.... java 如果我做
curl ec2-54-2xx-1xx-1xx.us-2.compute.amazonaws.com:8080
我得到以下网页。

但是，如果我尝试从外部机器的Web浏览器访问Web服务器，我得到以下错误。
Google Chrome's connection attempt to ec2-54-2xx-1xx-1xx.us-2.compute.amazonaws.com was rejected. The website may be down, or your network may not be properly configured. Currently I have configured my security groups (both inbound and outbound) to allow all traffic from any machine.
我试图从我的公司network.I这有可能是我的公司防火墙阻止它？ 如果是的话那为什么呢？
在安全设置中，我具有以下“入站”和“出站”值。
Type Protocol Port Range Source All traffic All All 0.0.0.0/0
我仍然无法从外部访问Web服务器。
loginAWS控制台并转至“安全组”部分在此处的“入站”中，添加名为“自定义TCP规则”的新规则并input自定义端口范围8080。
现在，在浏览器中input{ipaddress}：8080
默认情况下，AWS实例在没有任何端口可从Internet访问的情况下启动。 您需要更改您的VPC的安全组设置。 为此，请在EC2列表中select您的实例。 在你select你的实例的框架下，你会看到一堆关于实例的随机数据，包括“安全组” – 点击这个来修改这个实例的防火墙规则。 请注意，取决于您的VPC如何设置，更改这些规则可能会影响多个实例。
一旦你知道它的存在并且可以四处游荡，这是非常明显的。
