在 AWS 管理控制台中。
1 转到 Amazon EC2 选项卡
2 单击实例并记下安全组列中的安全组名称您想要打开它的实例。
3 单击链接安全组
4 单击步骤 2 中的安全组名称。
5 您应该会看到一个显示 SSH 的下拉列表,单击并选择自定义..
6 输入:
7 单击“保存”。
如果您还需要 UDP,请在步骤 6 中重复使用协议 UDP。
注意 1:阅读:http:// /en.wikipedia.org/wiki/Classless_Inter-Domain_Routing 了解更多信息...但不要尝试限制子网,直到您让它适用于全世界。
如果此后不起作用,则您的实例上可能有防火墙。我更喜欢 ubuntu,但试试这个: http://www.cyberciti.biz/faq/disable-linux-firewall-under-centos-rhel-fedora/(适用于 RedHat)
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:
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
此问题的解决方法是将 ../conf/red5.properties 处的默认端口更改为任何其他端口。我把它改成5081就可以了。
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.
