EC2:无法在Windows实例中打开端口5080 [英] ec2: cannot open port 5080 on windows instance
问题描述
我是pretty的新与EC2,防火墙设置等,所以我可能失去了一些东西很明显,但:
- 在我创建了一个开始使用Windows实例
- 在与具有5080指定的 安全组
- ,并用弹性IP相关
在该实例我有一个RED5服务器上运行。当我在127.0.0.1:5080运行服务器的话,我可以在该实例上的浏览器访问它,所以我知道了服务器的工作原理。
在我的弹性IP运行然而,我无法连接到它,无论是从实例中,也没有从外面。
当我从外面的世界运行telnet 75.101.147.86 5080我得到'连接被拒绝
任何如何调试这个线索,将是非常美联社preciated!
在此先感谢,

在AWS管理控制台。
1转到亚马逊EC2 标签
2点击实例并注意安全组名称在安集团列实例要打开它。
3点击链接安全组
4点击安全组名称第2步。
5,您应该会看到一个下拉菜单,上面写着 SSH ,单击它并选择自定义...
6输入:
协议TCP 从端口5080 到端口5080 来源(IP或集团)0.0.0.0/0 - 注1:
7单击保存。
如果您需要UDP也,然后重复步骤6使用协议UDP。
注1:阅读:<一href="http://en.wikipedia.org/wiki/Classless_Inter-Domain_Routing">http://en.wikipedia.org/wiki/Classless_Inter-Domain_Routing更多的信息...但不要尝试,直到你有它的工作为世界限制的子网。
如果它不后工作,那么你可能有一个防火墙的实例。我更多的是Ubuntu的家伙,但试试这个:<一href="http://www.cyberciti.biz/faq/disable-linux-firewall-under-centos-rhel-fedora/">http://www.cyberciti.biz/faq/disable-linux-firewall-under-centos-rhel-fedora/红帽
I'm pretty new with ec2, firewall settings etc, so I might be missing something obvious, but:
- I've created a 'getting started with windows' instance
- with a security group that has 5080 specified
- and is associated with an elastic ip
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.
When I run it on the elastic IP however, I can't connect to it, neither from within the instance nor from outside.
when I run telnet 75.101.147.86 5080 from the outside world i get 'connection refused'
Any clues on how to debug this would be highly appreciated!
Thanks in advance,
Martin
In the AWS management console.
1 goto Amazon EC2 tab
2 Click on Instances and note the Security Group Name from the Security Group column for the instance you want to open it for.
3 Click on the link Security Groups
4 Click on the Security Group Name from step 2.
5 You should see a dropdown that says SSH, click it and select Custom..
6 Enter:
Protocol TCP From Port 5080 To Port 5080 Source (IP or Group) 0.0.0.0/0 -- NOTE 1
7 Click Save.
If you need UDP also, then repeat using Protocol UDP in step 6.
NOTE 1: Read : http://en.wikipedia.org/wiki/Classless_Inter-Domain_Routing for more info... but don't try to limit the subnet until you have it working for the world.
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
