无法连接到本地套接字，连接被拒绝 [英] Can't connect to local socket, connection refused

问题描述

我已经在这里几天了，只是不能解决这个问题。我也把它放在Ubuntu论坛，没有听到。基本上，我有一个本地套接字在/ tmp / mysockets我在一个php脚本中创建成功 -

  if（（$ sock = socket_create（AF_UNIX，SOCK_STREAM，0））== b $ b {
 echosocket_create（）failed：reason：。 socket_strerror（socket_last_error（））。 \\\
; 
 exit（）; 
} 
  

但我无法连接，通过

  if（socket_connect（$ sock，$ sock_str）=== false）
 {
 echosocket_connect $ sock_str。 失败：原因：。 socket_strerror（socket_last_ $ 
 socket_close（$ sock）; 
 exit（）; 
} 
  

b $ b

这给我

警告：socket_connect（）：无法连接[111]：拒绝连接
在/ var / www / myscript.php在66号线上socket_connect（）
/ tmp / mysockets / sock失败：reason：Connection refused

现在，我认为这可能是一个权限问题，但我有chmod 777'/ tmp，mysockets和sock，这没有关系。可能是什么问题？

解决方案

所以，原来是应该在侦听这个套接字的进程崩溃 - 我在远程执行对我有用[0]丢个板砖[0]引用|举报|编辑删除管理回复次数：7

I've been at this for a few days now and just can't crack the problem. I've also put it up on the Ubuntu forum and heard nothing. Basically, I have a local socket in /tmp/mysockets which I create successfully in a php script--

if (($sock = socket_create(AF_UNIX, SOCK_STREAM,0)) === false) 
{
    echo "socket_create() failed: reason: " . socket_strerror(socket_last_error()) . "\n";
        exit();
}

but to which I cannot connect, via

if (socket_connect($sock, $sock_str) === false) 
{
        echo "socket_connect() on " . $sock_str . " failed: reason: " . socket_strerror(socket_last_$
        socket_close($sock);
        exit();
}

This gives me

Warning: socket_connect(): unable to connect [111]: Connection refused in /var/www/myscript.php on line 66 socket_connect() on /tmp/mysockets/sock failed: reason: Connection refused

Now, I thought this might be a permissions issue, but I've chmod 777'ed the /tmp, mysockets, and sock, and it doesn't matter. What could be the problem?

解决方案

So, it turns out that the process that was supposed to be listening for this socket crashed--I'm doing this remotely (and I'm just getting used to remote compiling/debugging) so I didn't see this at first. Sorry guys I described the problem incorrectly. @duskwuff you had the right idea.
