linux中使用php进行socket编程,报拒绝连接错误,请大家看看

本帖最后由 lovegis0101 于 2011-06-17 08:40:57 编辑 本人刚开始接触Linux和php和socket(呵呵....),在网上找了点资料,自己写了很基本的client端与server端两个php脚本,在Windows下测试,是可以通信的。之后把client端脚本放在Linux下,却报出如下错误:
PHP Warning:  socket_connect(): unable to connect [111]: Connection refused in /socketClient.php on line 12,12行是调用socket_connect方法,在这里出的错
系统环境是这样的,我在Windows系统主机里装了Linux虚拟机,Windows系统ip:192.168.0.2,Linux系统ip:192.168.102,两个系统网络通过桥接连接,Linux可以通过Windows来连接网络。
这个问题困扰我好几天了,在网上搜索,也没有找到解决方法,请大家帮忙看看啊
附上脚本代码:
server:
<br /><?php<br />// 设置一些基本的变量<br />global $lat,$lnt;<br />$host = "127.0.0.1";<br />$port = 8888;<br />// 设置超时时间<br />set_time_limit(0);<br />// 创建一个Socket<br />$commonProtocol = getprotobyname("tcp");<br />$socket = socket_create(AF_INET, SOCK_STREAM, $commonProtocol);<br /><br />//绑定Socket到端口<br />$result = socket_bind($socket, $host, $port) or die("Could not bind to socket\n");<br />$ret = socket_listen($socket, 5);<br />if($ret){<br />	while (true){<br />		$spawn = socket_accept($socket) or die("Could not accept incoming connection\n");;<br />		echo("socket connected\n");<br />		if(!$spawn) break;<br />		$output = "Welcome to the PHP Test Server.....nice\n";<br />		socket_write($spawn, $output, strlen ($output)) or die("error\n");<br />		while($input = socket_read($spawn, 64)){<br />			echo($input);<br />		}<br />		echo("\n");<br />		socket_close($spawn);<br />	}<br />}<br />?><br />

client:
<br /><?php<br />// 设置一些基本的变量<br />$host = "192.168.0.2";<br />$port = 8888;<br />// 设置超时时间<br />set_time_limit(0);<br />// 创建一个Socket<br />$commonProtocol = getprotobyname("tcp");<br />$socket = socket_create(AF_INET, SOCK_STREAM, $commonProtocol);<br />if(!$socket) echo "can't creat socket";<br />//绑定Socket到端口<br />$result = socket_connect($socket, $host, $port) or die(socket_strerror());<br />if($result){<br />	$output="hello server!";//lat:30.582029016593196;lnt:103.98662567138672<br />    socket_write($socket, $output, strlen ($output));<br />	$input = socket_read($socket, 1024);<br />	echo($input);<br />}<br />?><br />
