Question

我试图在EC2频道使用袜子但当我试图运行代码时,我犯了以下错误:

PHP Warning: socket_bind(): unable to bind address [99]: Cannot assign requested address in sockets_test.php on line 45

以下是相关守则的一部分:

$CFG = new stdClass();
$CFG->chat_serverip =  MY_PUBLIC_EC2_IP ;
$CFG->chat_serverport =  9111 ;

$listen_socket = socket_create(AF_INET, SOCK_STREAM, 0))
socket_bind($listen_socket, $CFG->chat_serverip, $CFG->chat_serverport)

This works just fine if I use 127.0.0.1 or the Private IP. My Security Group has the the rules:

0-65535 0.0.0.0/0 (TCP)
0-65535 0.0.0.0/0 (UDP)
ALL 0.0.0.0/0 (ICMP)

Answer 1

您无法与外部 IP 连接, 您必须与内部 IP 连接, 并设置一条规则允许该端口连接到外部 IP 和端口, 当它们连接到外部 IP 和端口时, 它会被转到内部 IP 上。

Answer 2

" 强势 " 幽灵 < /强者 " 有疑问,

we need bind the internal ip of We can see at ifconfig, not external IP of We can`t see at that.
