在 Amazon EC2 上打开 HTTP 端口 [英] Open a HTTP port on Amazon EC2

问题描述

我有一个在端口 8080 上运行的 Tomcat 7 实例，并且想在不同的端口上运行 Jenkins.另一种选择是更改 Jenkins URL.

I have a Tomcat 7 instance running on port 8080, and would like to run Jenkins on a different port. Another alternative would be to change the Jenkins URL.

如何将条目添加到允许的端口列表中?

我试过运行:sudo/sbin/iptables -A INPUT -p tcp --dport 8181 -j ACCEPT，但在 AWS 控制台中它只显示这些端口:

I have tried running: sudo /sbin/iptables -A INPUT -p tcp --dport 8181 -j ACCEPT, but in the AWS console it shows only these ports:

0 - 65535       0.0.0.0/0
22 (SSH)        0.0.0.0/0
80 (HTTP)       0.0.0.0/0
443 (HTTPS)     0.0.0.0/0
3306 (MYSQL)    0.0.0.0/0
8080 (HTTP*)    0.0.0.0/0

是否可以通过 AWS 控制台添加 HTTP 端口 (8181)?

Is it possible to add a HTTP port (8181) via the AWS console?

更新:

我已经尝试添加自定义的TCP端口，但后来没有得到HTTP协议，而且当我选择HTTP时，我无法指定端口！

I already tried adding a custom TCP port, but then it doesn't get the HTTP protocol, and when I select HTTP, I can't specify the port!

推荐答案

在 EC2 控制台中，查找您的实例的安全组"列.然后转到左侧导航菜单中网络和安全"上方的安全组"选项.它将显示您之前看到的安全组.单击它，它将显示一个分屏，其中上面的一个有 2 个选项卡:详细信息和入站.转至入站，在端口范围输入 8181 中输入您希望允许传入访问实例的 IP.不要忘记应用更改.

In EC2 console, look for the column "Security Group" of your instance. Then go to option "Security Groups" above "NETWORK & SECURITY" in navigation menu on left. It will show up the security group you saw before. Click on it, it will show a split screen where the one is above has 2 tabs: Details and Inbound. Go to Inbound, in port range input 8181 and source the ip you want to allow incoming access to instance. Don't forget to apply changes.
