ec2: cannot open port 5080 on windows instance
提问by Hoff
I'm pretty new with ec2, firewall settings etc, so I might be missing something obvious, but:
我对 ec2、防火墙设置等很陌生，所以我可能会遗漏一些明显的东西，但是：
- I've created a 'getting started with windows' instance
- with a security group that has 5080 specified
- and is associated with an elastic ip
- 我创建了一个“Windows 入门”实例
- 使用指定了 5080 的安全组
- 并与弹性 ip 相关联
On the instance I have a red5 server running. when I run the server it on 127.0.0.1:5080, i can access it from a browser on that instance, so I know the server works.
在实例上，我运行了一个 red5 服务器。当我在 127.0.0.1:5080 上运行服务器时，我可以从该实例上的浏览器访问它，所以我知道服务器正常工作。
When I run it on the elastic IP however, I can't connect to it, neither from within the instance nor from outside.
但是，当我在弹性 IP 上运行它时，无论是从实例内部还是外部，我都无法连接到它。
when I run telnet 75.101.147.86 5080 from the outside world i get 'connection refused'
当我从外界运行 telnet 75.101.147.86 5080 时，我得到“连接被拒绝”
Anyclues on how to debug this would be highly appreciated!
任何有关如何调试的线索将不胜感激！
Thanks in advance,
提前致谢，

In the AWS management console.
在 AWS 管理控制台中。
1 goto Amazon EC2tab
1 转到Amazon EC2选项卡
2 Click on Instancesand note the Security Group Namefrom the Security Groupcolumn for the instance you want to open it for.
2 单击实例并记下要为其打开的实例的安全组列中的安全组名称。
3 Click on the link Security Groups
3 单击链接安全组
4 Click on the Security Group Namefrom step 2.
4 单击步骤 2 中的安全组名称。
5 You should see a dropdown that says SSH, click it and select Custom..
5 您应该会看到一个下拉列表，上面写着SSH，单击它并选择Custom..
6 Enter:
6 输入：
Protocol TCP From Port 5080 To Port 5080 Source (IP or Group) 0.0.0.0/0 -- NOTE 1
Protocol TCP From Port 5080 To Port 5080 Source (IP or Group) 0.0.0.0/0 -- NOTE 1
7 Click Save.
7 单击保存。
If you need UDP also, then repeat using Protocol UDP in step 6.
如果您还需要 UDP，则在步骤 6 中重复使用协议 UDP。
NOTE 1: Read : http://en.wikipedia.org/wiki/Classless_Inter-Domain_Routingfor more info... but don't try to limit the subnet until you have it working for the world.
注意 1：阅读：http: //en.wikipedia.org/wiki/Classless_Inter-Domain_Routing了解更多信息......但不要试图限制子网，直到你让它为世界工作。
If it doesn't work after that then you may have a firewall on the instance. I'm more of an ubuntu guy, but try this : http://www.cyberciti.biz/faq/disable-linux-firewall-under-centos-rhel-fedora/for RedHat
如果之后它不起作用，那么您可能在实例上安装了防火墙。我更像是一个 ubuntu 人，但试试这个：http: //www.cyberciti.biz/faq/disable-linux-firewall-under-centos-rhel-fedora/for RedHat

A workaround for this problem to change the default port at ../conf/red5.properties to any other port. I changed it to 5081 and it works.
此问题的解决方法是将 ../conf/red5.properties 中的默认端口更改为任何其他端口。我将其更改为 5081 并且它有效。
